Question 12

Q

You are developing an application to transfer data between on-premises file servers and Azure
Blob storage. The application stores keys, secrets, and certificates in Azure Key Vault and makes
use of the Azure Key Vault APIs.
You want to configure the application to allow recovery of an accidental deletion of the key
vault or key vault objects for 90 days after deletion.
What should you do?
A. Run the Add-AzKeyVaultKey cmdlet.
B. Run the az keyvault update –enable-soft-delete true –enablepurge-protection true CLI.
C. Implement virtual network service endpoints for Azure Key Vault.
D. Run the az keyvault update –enable-soft-delete false CLI.

Answer

A

Answer: B
Explanation:
When soft-delete is enabled, resources marked as deleted resources are retained for a specified
period (90 days by default). The service further provides a mechanism for recovering the deleted
object, essentially undoing the deletion.
Purge protection is an optional Key Vault behavior and is not enabled by default. Purge
protection can only be enabled once soft-delete is enabled.
When purge protection is on, a vault or an object in the deleted state cannot be purged until the
retention period has passed. Soft-deleted vaults and objects can still be recovered, ensuring that
the retention policy will be followed.
The default retention period is 90 days, but it is possible to set the retention policy interval to a
value from 7 to 90 days through the Azure portal. Once the retention policy interval is set and
saved it cannot be changed for that vault.

photos to a web service which then stores the photos in Azure Storage Blob storage. The storage
account type is General-purpose V2.
When photos are uploaded, they must be processed to produce and save a mobile-friendly
version of the image. The process to produce a mobile-friendly version of the image must start in
less than one minute.
You need to design the process that starts the photo processing.
Solution: Trigger the photo processing from Blob storage events.
Does the solution meet the goal?
A. Yes
B. No

Answer

A

Answer: B
The answer (B) is correct. Because, the trick is in the “less than one minute” detail.
You can read about “..10-minute delay in processing new blobs..” in “3-Minimizing latency” description.
Microsoft says: “…..Use Event Grid instead of the Blob storage trigger for the following scenarios:”
1-Blob-only storage accounts: Blob-only storage accounts are supported for blob input and output bindings but not for blob triggers.
2-High-scale: High scale can be loosely defined as containers that have more than 100,000 blobs in them or storage accounts that have more than 100 blob updates per second.
3-Minimizing latency: If your function app is on the Consumption plan, there can be up to a ##10-minute delay in processing new blobs## if a function app has gone idle. To avoid this latency, you can switch to an App Service plan with Always On enabled. You can also use an Event Grid trigger with your Blob storage account. For an example, see the Event Grid tutorial.

What should you do?
A. Deploy the website to a virtual machine. Configure the virtual machine to automatically scale
when the CPU load is high.
B. Deploy the website to an App Service that uses the Shared service tier. Configure the App
Service plan to automatically scale when the CPU load is high.
C. Deploy the website to a virtual machine. Configure a Scale Set to increase the virtual machine
instance count when the CPU load is high.
D. Deploy the website to an App Service that uses the Standard service tier. Configure the App
Service plan to automatically scale when the CPU load is high.

Answer

A

Answer: D
Explanation:
Windows Azure Web Sites (WAWS) offers 3 modes: Standard, Free, and Shared.
Standard mode carries an enterprise-grade SLA (Service Level Agreement) of 99.9% monthly,
even for sites with just one instance.
Standard mode runs on dedicated instances, making it different from the other ways to buy
Windows Azure Web Sites.
Incorrect Answers:
B: Shared and Free modes do not offer the scaling flexibility of Standard, and they have some
important limits.
Shared mode, just as the name states, also uses shared Compute resources, and also has a CPU
limit. So, while neither Free nor Shared is likely to be the best choice for your production
environment due to these limits.

Question 35

Q

You develop an HTTP triggered Azure Function app to process Azure Storage blob data. The
app is triggered using an output binding on the blob.
The app continues to time out after four minutes. The app must process the blob data.
You need to ensure the app does not time out and processes the blob data.
Solution: Configure the app to use an App Service hosting plan and enable the Always On
setting.
Does the solution meet the goal?
A. Yes
B. No

Answer

A

Answer: B
Explanation:
Instead pass the HTTP trigger payload into an Azure Service Bus queue to be processed by a
queue trigger function and return an immediate HTTP success response.
Note: Large, long-running functions can cause unexpected timeout issues. General best practices
include:
Whenever possible, refactor large functions into smaller function sets that work together and
return responses fast. For example, a webhook or HTTP trigger function might require an
acknowledgment response within a certain time limit; it’s common for webhooks to require an
immediate response. You can pass the HTTP trigger payload into a queue to be processed by a
queue trigger function. This approach lets you defer the actual work and return an immediate
response.

Explanation:
Change feed support in Azure Blob Storage
The purpose of the change feed is to provide transaction logs of all the changes that occur to the
blobs and the blob metadata in your storage account. The change feed provides ordered,
guaranteed, durable, immutable, read-only log of these changes. Client applications can read
these logs at any time, either in streaming or in batch mode. The change feed enables you to
build efficient and scalable solutions that process change events that occur in your Blob Storage
account at a low cost.

“When your function app runs in the default Consumption plan, there may be a delay of up to several minutes between the blob being added or updated and the function being triggered. If you need low latency in your blob triggered functions, consider running your function app in an App Service plan.”

Question 41

Q

You develop and deploy an Azure App Service API app to a Windows-hosted deployment slot
named Development. You create additional deployment slots named Testing and Production.
You enable auto swap on the Production deployment slot.
You need to ensure that scripts run and resources are available before a swap operation occurs.
Solution: Update the app with a method named statuscheck to run the scripts. Update the app
settings for the app. Set the WEBSITE_SWAP_WARMUP_PING_PATH and
WEBSITE_SWAP_WARMUP_PING_STATUSES with a path to the new method and
appropriate response codes.
Does the solution meet the goal?
A. No
B. Yes

Answer

A

Answer: B
Should be YES?
You can also customize the warm-up behavior with one or both of the following app settings:
WEBSITE_SWAP_WARMUP_PING_PATH: The path to ping to warm up your site. Add this app setting by specifying a custom path that begins with a slash as the value. An example is /statuscheck. The default value is /.
WEBSITE_SWAP_WARMUP_PING_STATUSES: Valid HTTP response codes for the warm-up operation. Add this app setting with a comma-separated list of HTTP codes. An example is 200,202 . If the returned status code isn’t in the list, the warmup and swap operations are stopped. By default, all response codes are valid.
WEBSITE_WARMUP_PATH: A relative path on the site that should be pinged whenever the site restarts (not only during slot swaps). Example values include /statuscheck or the root path, /.

Question 42

Q

You are developing a web app that is protected by Azure Web Application Firewall (WAF). All
traffic to the web app is routed through an Azure Application Gateway instance that is used by
multiple web apps. The web app address is contoso.azurewebsites.net.
All traffic must be secured with SSL. The Azure Application Gateway instance is used by
multiple web apps.
You need to configure the Azure Application Gateway for the web app.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. In the Azure Application Gateway’s HTTP setting, enable the Use for App service setting.
B. Convert the web app to run in an Azure App service environment (ASE).
C. Add an authentication certificate for contoso.azurewebsites.net to the Azure Application
Gateway.
D. In the Azure Application Gateway’s HTTP setting, set the value of the Override backend path
option to contoso22.azurewebsites.net.

Answer

A

Answer: AD
Explanation:
D: The ability to specify a host override is defined in the HTTP settings and can be applied to
any back-end pool during rule creation.
The ability to derive the host name from the IP or FQDN of the back-end pool members. HTTP
settings also provide an option to dynamically pick the host name from a back-end pool
member’s FQDN if configured with the option to derive host name from an individual back-end
pool member.
A (not C): SSL termination and end to end SSL with multi-tenant services.
In case of end to end SSL, trusted Azure services such as Azure App service web apps do not
require whitelisting the backends in the application gateway. Therefore, there is no need to add
any authentication certificates.

Question 43

Q

You develop a software as a service (SaaS) offering to manage photographs. Users upload
photos to a web service which then stores the photos in Azure Storage Blob storage. The storage
account type is General-purpose V2.
When photos are uploaded, they must be processed to produce and save a mobile-friendly
version of the image. The process to produce a mobile-friendly version of the image must start in
less than one minute.
You need to design the process that starts the photo processing.
Solution: Use the Azure Blob Storage change feed to trigger photo processing.
Does the solution meet the goal?
A. Yes
B. No

Answer

A

Answer: B
Explanation:
The change feed is a log of changes that are organized into hourly segments but appended to and
updated every few minutes. These segments are created only when there are blob change events
that occur in that hour.
Instead catch the triggered event, so move the photo processing to an Azure Function triggered
from the blob upload.

Question 44

Q

You are developing a web application that runs as an Azure Web App. The web application
stores data in Azure SQL Database and stores files in an Azure Storage account. The web
application makes HTTP requests to external services as part of normal operations.
The web application is instrumented with Application Insights. The external services are
OpenTelemetry compliant.
You need to ensure that the customer ID of the signed in user is associated with all operations
throughout the overall system.
What should you do?
A. Add the customer ID for the signed in user to the CorrelationContext in the web application
B. On the current SpanContext, set the TraceId to the customer ID for the signed in user
C. Set the header Ocp-Apim-Trace to the customer ID for the signed in user
D. Create a new SpanContext with the TraceFlags value set to the customer ID for the signed in
user

Answer

A

Answer: A
“I would choose option A, Add the customer ID for the signed in user to the CorrelationContext in the web application.

The CorrelationContext is a way to associate contextual information with a request as it flows through the system. It allows you to track a request as it passes through different components of the system, and to identify related log entries and telemetry data. By adding the customer ID to the CorrelationContext in the web application, you can ensure that it is associated with all operations throughout the overall system. This will allow you to track the request and identify related log entries and telemetry data for a specific customer.

Question 45

Q

You develop an HTTP triggered Azure Function app to process Azure Storage blob data. The
app is triggered using an output binding on the blob.
The app continues to time out after four minutes. The app must process the blob data.
You need to ensure the app does not time out and processes the blob data.
Solution: Update the functionTimeout property of the host.json project file to 10 minutes.
Does the solution meet the goal?
A. Yes
B. No

Answer

A

Answer: B
Explanation:
Instead pass the HTTP trigger payload into an Azure Service Bus queue to be processed by a
queue trigger function and return an immediate HTTP success response.
Note: Large, long-running functions can cause unexpected timeout issues. General best practices
include:
Whenever possible, refactor large functions into smaller function sets that work together and
return responses fast. For example, a webhook or HTTP trigger function might require an
acknowledgment response within a certain time limit; it’s common for webhooks to require an
immediate response. You can pass the HTTP trigger payload into a queue to be processed by a
queue trigger function. This approach lets you defer the actual work and return an immediate
response.

Question 46

Q

You are developing an Azure Durable Function to manage an online ordering process.
The process must call an external API to gather product discount information.
You need to implement the Azure Durable Function.
Which Azure Durable Function types should you use? Each correct answer presents part of the
solution.
NOTE: Each correct selection is worth one point.
A. Orchestrator
B. Entity
C. Client
D. Activity

Answer

A

Answer: A, D
“ Like orchestrator functions, entity functions are functions with a special trigger type, entity trigger.” - u can not call Entity from Orchestrator… right answer is Orchestrator and Activity

Question 47

Q

You develop Azure Durable Functions to manage vehicle loans.
The loan process includes multiple actions that must be run in a specified order. One of the
actions includes a customer credit check process, which may require multiple days to process.
You need to implement Azure Durable Functions for the loan process.
Which Azure Durable Functions type should you use?
A. orchestrator
B. client
C. entity
D. activity

Answer

A

Answer: A
Explanation:
Durable Functions is an extension of Azure Functions. You can use an orchestrator function to
orchestrate the execution of other Durable functions within a function app. Orchestrator
functions have the following characteristics:
Orchestrator functions define function workflows using procedural code. No declarative schemas
or designers are needed.
Orchestrator functions can call other durable functions synchronously and asynchronously.
Output from called functions can be reliably saved to local variables.
Orchestrator functions are durable and reliable. Execution progress is automatically
checkpointed when the function “awaits” or “yields”. Local state is never lost when the process
recycles or the VM reboots.
Orchestrator functions can be long-running. The total lifespan of an orchestration instance can be
seconds, days, months, or never-ending.

Question 48

Q

You develop Azure Web Apps for a commercial diving company. Regulations require that all
divers fill out a health questionnaire every 15 days after each diving job starts.
You need to configure the Azure Web Apps so that the instance count scales up when divers are
filling out the questionnaire and scales down after they are complete.
You need to configure autoscaling.
What are two possible auto scaling configurations to achieve this goal? Each correct answer
presents a complete solution.
NOTE: Each correct selection is worth one point.
A. Recurrence profile
B. CPU usage-based autoscaling
C. Fixed date profile
D. Predictive autoscaling

Answer

A

Answer: B,D
I think it should
B. CPU usage-based autoscaling
D. Predictive autoscaling

A. Recurrence profile is used to schedule the scaling of resources at specific times or dates, but it does not meet the requirement to scale up when divers are filling out the questionnaire and scale down after they are complete. It only triggers scaling based on a set schedule, not based on actual usage.

C. Fixed date profile is used to specify the number of instances at a specific date and time, but it also does not meet the requirement to dynamically scale based on actual usage. It only sets a fixed number of instances and does not adjust based on changing workloads.

Question 49

Q

You are building a website that uses Azure Blob storage for data storage. You configure Azure
Blob storage lifecycle to move all blobs to the archive tier after 30 days.
Customers have requested a service-level agreement (SLA) for viewing data older than 30 days.
You need to document the minimum SLA for data recovery.
Which SLA should you use?
A. at least two days
B. between one and 15 hours
C. at least one day
D. between zero and 60 minutes

Answer

A

Answer: B
Explanation:
The archive access tier has the lowest storage cost. But it has higher data retrieval costs
compared to the hot and cool tiers. Data in the archive tier can take several hours to retrieve
depending on the priority of the rehydration. For small objects, a high priority rehydrate may
retrieve the object from archive in under 1 hour.

Question 50

Q

You are developing an Azure solution to collect point-of-sale (POS) device data from
2,000 stores located throughout the world. A single device can produce 2 megabytes (MB) of
data every 24 hours. Each store location has one to five devices that send data.
You must store the device data in Azure Blob storage. Device data must be correlated based on a
device identifier. Additional stores are expected to open in the future.
You need to implement a solution to receive the device data.
Solution: Provision an Azure Event Grid. Configure the machine identifier as the partition key
and enable capture.
Does the solution meet the goal?
A. Yes
B. No

Answer

A

Answer: A
Partitions - 2000 per CU - Dedicated Plan - So we can have 2K+ partitions in Event Hub
Size allowed - Yes

Question 51

Q

You develop Azure solutions.
A .NET application needs to receive a message each time an Azure virtual machine finishes
processing data. The messages must NOT persist after being processed by the receiving
application.
You need to implement the .NET object that will receive the messages.
Which object should you use?
A. QueueClient
B. SubscriptionClient
C. TopicClient
D. CloudQueueClient

Answer

A

Answer: A

Azure.Storage.Queues.QueueClient: .NET v12
Azure.Storage.Queues.CloudQueueClient: .NET v11 (Legacy)

So, the question is really about what kind of queue message tool you should use. And the key word here is that “message must NOT persist after being processed”.

Azure.Storage.Queues.QueueClient supports “At-Most-Once” deliver mode, while Azure.Storage.Queues.CloudQueueClient doesn’t.

Question 52

Q

You develop Azure solutions.
You must connect to a No-SQL globally-distributed database by using the .NET API.
You need to create an object to configure and execute requests in the database.
Which code segment should you use?
A. new Container(EndpointUri, PrimaryKey);
B. new Database(EndpointUri, PrimaryKey);
C. new CosmosClient(EndpointUri, PrimaryKey);

Answer

A

Answer: C
Explanation:
Example:
// Create a new instance of the Cosmos Client
this.cosmosClient = new CosmosClient(EndpointUri, PrimaryKey)
//ADD THIS PART TO YOUR CODE
await this.CreateDatabaseAsync();

Question 53

Q

You have an existing Azure storage account that stores large volumes of data across multiple
containers.
You need to copy all data from the existing storage account to a new storage account. The copy
process must meet the following requirements:
 Automate data movement.
 Minimize user input required to perform the operation.
 Ensure that the data movement process is recoverable.
What should you use?
A. AzCopy
B. Azure Storage Explorer
C. Azure portal
D. .NET Storage Client Library

Answer

A

Answer: A
Explanation:
You can copy blobs, directories, and containers between storage accounts by using the AzCopy
v10 command-line utility.
The copy operation is synchronous so when the command returns, that indicates that all files
have been copied.

Question 54

Q

You are developing an Azure Cosmos DB solution by using the Azure Cosmos DB SQL API.
The data includes millions of documents. Each document may contain hundreds of properties.
The properties of the documents do not contain distinct values for partitioning. Azure Cosmos
DB must scale individual containers in the database to meet the performance needs of the
application by spreading the workload evenly across all partitions over time.
You need to select a partition key.
Which two partition keys can you use? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. a single property value that does not appear frequently in the documents
B. a value containing the collection name
C. a single property value that appears frequently in the documents
D. a concatenation of multiple property values with a random suffix appended
E. a hash suffix appended to a property value

Answer

A

Answer: D,E
Explanation:
You can form a partition key by concatenating multiple property values into a single artificial
partitionKey property. These keys are referred to as synthetic keys.
Another possible strategy to distribute the workload more evenly is to append a random number
at the end of the partition key value. When you distribute items in this way, you can perform
parallel write operations across partitions.
Note: It’s the best practice to have a partition key with many distinct values, such as hundreds or
thousands. The goal is to distribute your data and workload evenly across the items associated
with these partition key values. If such a property doesn’t exist in your data, you can construct a
synthetic partition key.

Question 55

Q

You develop and deploy a web application to Azure App Service. The application accesses data
stored in an Azure Storage account. The account contains several containers with several blobs
with large amounts of data. You deploy all Azure resources to a single region.
You need to move the Azure Storage account to the new region. You must copy all data to the
new region.
What should you do first?
A. Export the Azure Storage account Azure Resource Manager template
B. Initiate a storage account failover
C. Configure object replication for all blobs
D. Use the AzCopy command line tool
E. Create a new Azure Storage account in the current region
F. Create a new subscription in the current region

Answer

A

Answer: A
Explanation:
To move a storage account, create a copy of your storage account in another region. Then, move
your data to that account by using AzCopy, or another tool of your choice and finally, delete the
resources in the source region.
To get started, export, and then modify a Resource Manager template

Question 56

Q

An organization deploys Azure Cosmos DB.
You need to ensure that the index is updated as items are created, updated, or deleted.
What should you do?
A. Set the indexing mode to Lazy.
B. Set the value of the automatic property of the indexing policy to False.
C. Set the value of the EnableScanInQuery option to True.
D. Set the indexing mode to Consistent.

Answer

A

Answer: D
Explanation:
Azure Cosmos DB supports two indexing modes:
Consistent: The index is updated synchronously as you create, update or delete items. This
means that the consistency of your read queries will be the consistency configured for the
account.
None: Indexing is disabled on the container.

Question 57

Q

You are developing a .Net web application that stores data in Azure Cosmos DB. The application
must use the Core API and allow millions of reads and writes. The Azure Cosmos DB account
has been created with multiple write regions enabled. The application has been deployed to the
East US2 and Central US regions.
You need to update the application to support multi-region writes.
What are two possible ways to achieve this goal? Each correct answer presents part of the
solution.
NOTE: Each correct selection is worth one point.
A. Update the ConnectionPolicy class for the Cosmos client and populate the PreferredLocations
property based on the geo-proximity of the application.
B. Update Azure Cosmos DB to use the Strong consistency level. Add indexed properties to the
container to indicate region.
C. Update the ConnectionPolicy class for the Cosmos client and set the
UseMultipleWriteLocations property to true.
D. Create and deploy a custom conflict resolution policy.
E. Update Azure Cosmos DB to use the Session consistency level. Send the SessionToken
property value from the FeedResponse object of the write action to the end-user by using a
cookie.

Answer

A

Answer: A,C
The goal is

“You need to update the application to support multi-region writes”,

that is enable multi-region writes (bool, option C) and add the regions (option A)
Then you have to apply the Conflict resolution policies.This can be LLW(default, not mentioned) or custom (option D).

Hence : there is only ONE way to to support multi-region writes (both apply C AND A) and there are subsequently TWO ways to apply the Conflict resolution policies (@ SQL) to solve write, update and delete conflicts of which one is mentioned in the question (D).
To support multi-region writes I would answer A and C , but they have to be set both, not one or the other.

Question 58

Q

You are developing an application to store business-critical data in Azure Blob storage.
The application must meet the following requirements:
 Data must not be modified or deleted for a user-specified interval.
 Data must be protected from overwrites and deletes.
 Data must be written once and allowed to be read many times.
You need to protect the data in the Azure Blob storage account.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Configure a time-based retention policy for the storage account.
B. Create an account shared-access signature (SAS).
C. Enable the blob change feed for the storage account.
D. Enable version-level immutability support for the storage account.
E. Enable point-in-time restore for containers in the storage account.
F. Create a service shared-access signature (SAS).

Answer

A

Answer: A,D
A. Configure a time-based retention policy for the storage account
- A time-based retention policy stores blob data in a Write-Once, Read-Many (WORM) format for a specified interval. When a time-based retention policy is set, clients can create and read blobs, but can’t modify or delete them. After the retention interval has expired, blobs can be deleted but not overwritten.
D. Before you can apply a time-based retention policy to a blob version, you must enable support for version-level immutability.

Question 59

Q

You are updating an application that stores data on Azure and uses Azure Cosmos DB for
storage. The application stores data in multiple documents associated with a single username.
The application requires the ability to update multiple documents for a username in a single
ACID operation.
You need to configure Azure Cosmos DB.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Create a collection sharded on username to store documents.
B. Configure Azure Cosmos DB to use the Gremlin API.
C. Create an unsharded collection to store documents.
D. Configure Azure Cosmos DB to use the MongoDB API.

Answer

A

Answer: CD
Explanation:
C: Multi-document transactions, Requirements
Multi-document transactions are supported within an unsharded collection in API version 4.0.
Multi-document transactions are not supported across collections or in sharded collections in 4.0.
D: In Azure Cosmos DB for MongoDB, operations on a single document are atomic. Multidocument transactions enable applications to execute atomic operations across multiple
documents. It offers “all-or-nothing” semantics to the operations. On commit, the changes made
inside the transactions are persisted and if the transaction fails, all changes inside the transaction
are discarded.
Multi-document transactions follow ACID semantics:
Atomicity: All operations treated as one
Consistency: Data committed is valid
Isolation: Isolated from other operations
Durability: Transaction data is persisted when client is told so

Question 60

Q

You develop Azure solutions.
You must connect to a No-SQL globally-distributed database by using the .NET API.
You need to create an object to configure and execute requests in the database.
Which code segment should you use?
A.
database_name = ‘MyDatabase’
database =
client.create_database_if_not_exists(id=database_name)
B.
client = CosmosClient(endpoint, key)
C.
container_name = ‘MyContainer’
container = database.create_container_if_not_exists(
id=container_name, partition_key=PartitionKey(path=”/lastName”),
offer_throughput=400 )

Answer

A

Answer: B
CosmosClient has to be created before you can do option A and C to create databases and execute requests.

client = CosmosClient(endpoint, key)
database_name = ‘MyDatabase’
database = client.create_database_if_not_exists(id=database_name)
container_name = ‘MyContainer’
container = database.create_container_if_not_exists(
id=container_name, partition_key=PartitionKey(path=”/lastName”), offer_throughput=400 )

Question 61

Q

You develop a web application that provides access to legal documents that are stored on Azure
Blob Storage with version-level immutability policies. Documents are protected with both timebased policies and legal hold policies. All time-based retention policies have the
AllowProtectedAppendWrites property enabled.
You have a requirement to prevent the user from attempting to perform operations that would
fail only when a legal hold is in effect and when all other policies are expired.
You need to meet the requirement.
Which two operations should you prevent? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. adding data to documents
B. deleting documents
C. creating documents
D. overwriting existing documents

Answer

A

Answer: BD
Explanation:
The Append Block operation is permitted only for policies with the
allowProtectedAppendWrites or allowProtectedAppendWritesAll property enabled.
The AllowProtectedAppendWrites property setting allows for writing new blocks to an append
blob while maintaining immutability protection and compliance. If this setting is enabled, you
can create an append blob directly in the policy-protected container, and then continue to add
new blocks of data to the end of the append blob with the Append Block operation. Only new
blocks can be added; any existing blocks can’t be modified or deleted. Enabling this setting
doesn’t affect the immutability behavior of block blobs or page blobs.

Question 62

Q

You are developing a Java application that uses Cassandra to store key and value data. You plan
to use a new Azure Cosmos DB resource and the Cassandra API in the application. You create
an Azure Active Directory (Azure AD) group named Cosmos DB Creators to enable
provisioning of Azure Cosmos accounts, databases, and containers.
The Azure AD group must not be able to access the keys that are required to access the data.
You need to restrict access to the Azure AD group.
Which role-based access control should you use?
A. DocumentDB Accounts Contributor
B. Cosmos Backup Operator
C. Cosmos DB Operator
D. Cosmos DB Account Reader

Answer

A

Answer: C
Explanation:
Azure Cosmos DB now provides a new RBAC role, Cosmos DB Operator. This new role lets
you provision Azure Cosmos accounts, databases, and containers, but can’t access the keys that
are required to access the data. This role is intended for use in scenarios where the ability to
grant access to Azure Active Directory service principals to manage deployment operations for
Cosmos DB is needed, including the account, database, and containers.

Question 63

Q

You are developing a website that will run as an Azure Web App. Users will authenticate by
using their Azure Active Directory (Azure AD) credentials.
You plan to assign users one of the following permission levels for the website: admin, normal,
and reader. A user’s Azure AD group membership must be used to determine the permission
level.
You need to configure authorization.
Solution: Configure the Azure Web App for the website to allow only authenticated requests and
require Azure AD log on.
Does the solution meet the goal?
A. Yes
B. No

Answer

A

Answer: B
Explanation:
Instead in the Azure AD application’s manifest, set value of the groupMembershipClaims option
to All. In the website, use the value of the groups claim from the JWT for the user to determine
permissions.

Question 64

Q

You are developing a website that will run as an Azure Web App. Users will authenticate by
using their Azure Active Directory (Azure AD) credentials.
You plan to assign users one of the following permission levels for the website: admin, normal,
and reader. A user’s Azure AD group membership must be used to determine the permission
level.
You need to configure authorization.
Solution:
 Create a new Azure AD application. In the application’s manifest, set value of the
groupMembershipClaims option to All.
 In the website, use the value of the groups claim from the JWT for the user to determine
permissions.
Does the solution meet the goal?
A. Yes
B. No

Answer

A

Answer: A
Explanation:
To configure Manifest to include Group Claims in Auth Token
1. Go to Azure Active Directory to configure the Manifest. Click on Azure Active
Directory, and go to App registrations to find your application:
2. Click on your application (or search for it if you have a lot of apps) and edit the Manifest
by clicking on it.
3. Locate the “groupMembershipClaims” setting. Set its value to either “SecurityGroup” or
“All”. To help you decide which:
 “SecurityGroup” - groups claim will contain the identifiers of all security groups
of which the user is a member.
 “All” - groups claim will contain the identifiers of all security groups and all
distribution lists of which the user is a member
Now your application will include group claims in your manifest and you can use this fact in
your code.

Answer 65

A

Answer:A
The roles get assigned by AD groups, so the requirement “A user’s Azure AD group membership must be used to determine the permission level” is met.

This solution should be answered with “yes”.

This scenario has 2 solutions provided as the approach using the “groupMembershipClaims” is possible as well.
That’s OK as it says “Some question sets might have more than one correct solution, while others might not have a correct solution.”

Answer 66

Storage Blob storage.

Answer 70

A

Answer: C
Explanation:
Azure Active Directory Managed Service Identity (MSI) gives your code an automatically
managed identity for authenticating to Azure services, so that you can keep credentials out of
your code.
Note: Use the authentication-managed-identity policy to authenticate with a backend service
using the managed identity. This policy essentially uses the managed identity to obtain an access
token from Azure Active Directory for accessing the specified resource. After successfully
obtaining the token, the policy will set the value of the token in the Authorization header using
the Bearer scheme.
Incorrect Answers:
A: Use the authentication-basic policy to authenticate with a backend service using Basic
authentication. This policy effectively sets the HTTP Authorization header to the value
corresponding to the credentials provided in the policy.
B: Anonymous is no authentication at all.
D: Your code needs credentials to authenticate to cloud services, but you want to limit the
visibility of those credentials as much as possible. Ideally, they never appear on a developer’s
workstation or get checked-in to source control. Azure Key Vault can store credentials securely
so they aren’t in your code, but to retrieve them you need to authenticate to Azure Key Vault. To
authenticate to Key Vault, you need a credential! A classic bootstrap problem.

These formats are supported in the lists of paths to purge:
 Single path purge: Purge individual assets by specifying the full path of the asset (without
the protocol and domain), with the file extension, for example, /pictures/strasbourg.png;
 Wildcard purge: Asterisk () may be used as a wildcard. Purge all folders, subfolders,
and files under an endpoint with / in the path or purge all subfolders and files under a
specific folder by specifying the folder followed by /, for example, /pictures/.
 Root domain purge: Purge the root of the endpoint with “/” in the path.

Answer: C
Explanation:
Use the authentication-managed-identity policy to authenticate with a backend service using the
managed identity of the API Management service. This policy essentially uses the managed
identity to obtain an access token from Azure Active Directory for accessing the specified
resource. After successfully obtaining the token, the policy will set the value of the token in the
Authorization header using the Bearer scheme.

Explanation:
Add the validate-jwt policy to validate the OAuth token for every incoming request.
Incorrect Answers:
A: The jsonp policy adds JSON with padding (JSONP) support to an operation or an API to
allow cross-domain calls from JavaScript browser-based clients. JSONP is a method used in
JavaScript programs to request data from a server in a different domain. JSONP bypasses the
limitation enforced by most web browsers where access to web pages must be in the same
domain.
JSONP - Adds JSON with padding (JSONP) support to an operation or an API to allow crossdomain calls from JavaScript browser-based clients.

Answer: A,B
To configure the Azure App Service REST API to retrieve and update user profile information stored in Azure Active Directory (Azure AD), you should use the following tools:
A. Microsoft Graph API: The Microsoft Graph API allows you to interact with data in Azure AD, including retrieving and updating user profile information.
B. Microsoft Authentication Library (MSAL): MSAL is used for handling authentication in your application. It helps you authenticate users and acquire access tokens, which are necessary when making requests to the Microsoft Graph API.
Therefore, the correct answers are A (Microsoft Graph API) and B (Microsoft Authentication Library).

Answer 79

A

Answer: A,D
There’re two ways to create a SAS:
(1). The “standard” way to generate a SAS token is to use the storage account key.
(2). by using “managed identities” with a technique is called a “user delegation” SAS, and it allows you to sign the signature with Azure AD credentials instead of with the storage account key.
This question is (2) hence A, D is correct

Answer 80

A

Answer: A
Explanation:
To give a managed identity access to an Azure resource, you need to add a role to the target
resource for that identity.
Note: To easily authenticate access to other resources that are protected by Azure Active
Directory (Azure AD) without having to sign in and provide credentials or secrets, your logic
app can use a managed identity (formerly known as Managed Service Identity or MSI). Azure
manages this identity for you and helps secure your credentials because you don’t have to
provide or rotate secrets.
If you set up your logic app to use the system-assigned identity or a manually created, userassigned identity, the function in your logic app can also use that same identity for
authentication.

Answer: C,D
C: “Because Azure Functions uses the change feed processor behind the scenes, it automatically parallelizes change processing across your container’s partitions.”
D: “You can use the change feed pull model to consume the Azure Cosmos DB change feed at your own pace. Similar to the change feed processor, you can use the change feed pull model to parallelize the processing of changes across multiple change feed consumers.”

Answer 82

A

Answer: B
To validate the Azure AD request in the app code when using Twitter as the identity provider, you should validate the ID token signature (option B).

The ID token is a JSON Web Token (JWT) that contains claims about the user. It is signed by Azure AD using a private key, and the signature can be verified using the corresponding public key. Validating the ID token signature ensures that the token was issued by a trusted source and that it has not been tampered with in transit.

Option A, validating the ID token header, is not sufficient for validating the entire ID token. The header only contains metadata about the token, such as the algorithm used for signing.

Option C, validating the HTTP response code, is unrelated to validating the ID token.

Option D, validating the tenant ID, is important for ensuring that the app is only accepting tokens from a trusted Azure AD tenant, but it does not ensure the integrity of the token itself.

Answer 83

A

Answer: A
A. Generate a shared access signature (SAS) for the Azure Blob storage account and provide the SAS to all developers.

A shared access signature (SAS) is a secure token that can be used to grant temporary and revocable access to a blob container or individual blobs. You can specify an expiration time for the SAS, so it will automatically expire after the two-month time period, making the blob storage account no longer accessible to the developers.
This approach allows you to grant the developers the necessary access to the Azure Blob storage account while still maintaining control over the access, and it also allows you to revoke access easily after the two-month time period.

Answer 84

A

Answer: B, C
Explanation:
B: MFA Enabled by conditional access policy. It is the most flexible means to enable two-step
verification for your users. Enabling using conditional access policy only works for Azure MFA
in the cloud and is a premium feature of Azure AD.
C: Multi-Factor Authentication comes as part of the following offerings:
 Azure Active Directory Premium licenses - Full featured use of Azure Multi-Factor
Authentication Service (Cloud) or Azure Multi-Factor Authentication Server (Onpremises).
 Multi-Factor Authentication for Office 365
 Azure Active Directory Global Administrators

Answer 85

A

Answer: A
Explanation:
A service SAS is secured with the storage account key. A service SAS delegates access to a
resource in only one of the Azure Storage services: Blob storage, Queue storage, Table storage,
or Azure Files.
Stored access policies give you the option to revoke permissions for a service SAS without
having to regenerate the storage account keys.
Incorrect Answers:
B: Account SAS is specified at the account level. It is secured with the storage account key.
C: A user delegation SAS applies to Blob storage only.

Answer 86

A

Answer: C
Explanation:
oid -The object identifier for the user in Azure AD. This value is the immutable and non-reusable
identifier of the user. Use this value, not email, as a unique identifier for users; email addresses
can change. If you use the Azure AD Graph API in your app, object ID is that value used to
query profile information.

Answer: A
External collaboration settings let you specify what roles in your organization can invite external users for B2B collaboration. These settings also include options for allowing or blocking specific domains, and options for restricting what external guest users can see in your Azure AD directory.
So, you use B2B external collaboration to invite guests into your Azure AD tenant.

I vote for Custom Policies. Both Custom Policies and User Flows support external identity providers, but because of required custom in-house providers support, I’d choose Custom Policies over the User Flows

Answer 89

A

Answer: AE
Explanation:
A: Secure environment variables
Another method (another than a secret volume) for providing sensitive information to containers
(including Windows containers) is through the use of secure environment variables.
E: Use a secret volume to supply sensitive information to the containers in a container group.
The secret volume stores your secrets in files within the volume, accessible by the containers in
the container group. By storing secrets in a secret volume, you can avoid adding sensitive data
like SSH keys or database credentials to your application code.

Answer: A
Explanation:
Data Connect grants a more granular control and consent model: you can manage data, see who
is accessing it, and request specific properties of an entity. This enhances the Microsoft Graph
model, which grants or denies applications access to entire entities.
Microsoft Graph Data Connect augments Microsoft Graph’s transactional model with an
intelligent way to access rich data at scale. The data covers how workers communicate,
collaborate, and manage their time across all the applications and services in Microsoft 365.
Incorrect:
Not B: The Microsoft Graph API is a RESTful web API that enables you to access Microsoft
Cloud service resources. After you register your app and get authentication tokens for a user or
service, you can make requests to the Microsoft Graph API.
A simplistic definition of a Graph API is an API that models the data in terms of nodes and
edges (objects and relationships) and allows the client to interact with multiple nodes in a single
request.
Not C: Microsoft Graph connectors, your organization can index third-party data so that it
appears in Microsoft Search results.
With Microsoft Graph connectors, your organization can index third-party data so that it appears

Microsoft identity platform and OAuth 2.0 authorization code flow, Request an authorization
code
https://login.microsoftonline.com/{tenant}/oauth2/v2.0/authorize?
The authorization code flow begins with the client directing the user to the /authorize endpoint.
In this request, the client requests the openid, offline_access, and
https://graph.microsoft.com/mail.read permissions from the user.
Parameters include:
* scope required
A space-separated list of scopes that you want the user to consent to. For the /authorize leg of the
request, this parameter can cover multiple resources. This value allows your app to get consent
for multiple web APIs you want to call.

Answer 92

A

Answer: D Explanation: An Azure Function can be used with managed identity to rotate service principal keys. Then an app can use service principal keys to authenticate to Key Vault to check for new versions of the app secret. As long as it does so before the old secret expires it can successfully update its cache with the new secret allowing a smooth transition to the new version.

Answer: B
Explanation:
Encryption keys
Customer-managed keys
Before DEKs get stored in Azure Cosmos DB, they are wrapped by a customer-managed key
(CMK). By controlling the wrapping and unwrapping of DEKs, CMKs effectively control the
access to the data that’s encrypted with their corresponding DEKs. CMK storage is designed as
an extensible, with a default implementation that expects them to be stored in Azure Key Vault.

Share Session State Across Applications: While PostgreSQL can store session state, sharing session state across multiple ASP.NET applications is not its primary use case. It requires additional configuration and programming to handle session state management.
Controlled, Concurrent Access for Multiple Readers and a Single Writer: PostgreSQL supports concurrent access, but managing this for session state data would require additional programming effort.
Save Full HTTP Responses for Concurrent Requests: PostgreSQL is not designed for caching full HTTP responses. It is primarily a relational database for structured data, not a cache for HTTP responses.

B, E: DeliveryCount
Number of deliveries that have been attempted for this message. The count is incremented when
a message lock expires, or the message is explicitly abandoned by the receiver. This property is
read-only.
C, E: SequenceNumber
The sequence number is a unique 64-bit integer assigned to a message as it is accepted and
stored by the broker and functions as its true identifier. For partitioned entities, the topmost 16
bits reflect the partition identifier. Sequence numbers monotonically increase and are gapless.
They roll over to 0 when the 48-64 bit range is exhausted. This property is read-only.

Answer: B, C
Explanation:
There are three types of availability tests:
 URL ping test: a simple test that you can create in the Azure portal.
 Multi-step web test: A recording of a sequence of web requests, which can be played
back to test more complex scenarios. Multi-step web tests are created in Visual Studio
Enterprise and uploaded to the portal for execution.
 Custom Track Availability Tests: If you decide to create a custom application to run
availability tests, the TrackAvailability() method can be used to send the results to
Application Insights.

Answer 102

A

Answer: B
Explanation:
You can create an Azure Function with TrackAvailability() that will run periodically according
to the configuration given in TimerTrigger function with your own business logic. The results of
this test will be sent to your Application Insights resource, where you will be able to query for
and alert on the availability results data. This allows you to create customized tests similar to
what you can do via Availability Monitoring in the portal. Customized tests will allow you to
write more complex availability tests than is possible using the portal UI, monitor an app inside
of your Azure VNET, change the endpoint address, or create an availability test even if this
feature is not available in your region.

B: The allkeys-lru policy evict keys by trying to remove the less recently used (LRU) keys first,
in order to make space for the new data added. Use the allkeys-lru policy when you expect a
power-law distribution in the popularity of your requests, that is, you expect that a subset of
elements will be accessed far more often than the rest.
C: volatile-lru: evict keys by trying to remove the less recently used (LRU) keys first, but only
among keys that have an expire set, in order to make space for the new data added.
Note: The allkeys-lru policy is more memory efficient since there is no need to set an expire for
the key to be evicted under memory pressure.

D. Build an Azure Monitor action group that suppresses the alerts: Incorrect. This requires additional configuration and may not specifically target the offline processing alerts.

Answer 110

A

Answer: B
There must be a way to tell our redis that logged off users must not be prioritized.

Answer 111

A

Answer: C
Explanation:
Exceptions in web applications can be reported with Application Insights. You can correlate
failed requests with exceptions and other events on both the client and server so that you can
quickly diagnose the causes.
When an exception occurs, you can automatically collect a debug snapshot from your live web
application. The debug snapshot shows the state of source code and variables at the moment the
exception was thrown. The Snapshot Debugger in Azure Application Insights:
Monitors system-generated logs from your web app.
Collects snapshots on your top-throwing exceptions.
Provides information you need to diagnose issues in production.

Answer 112

A

Answer: AB
Explanation:
The App Configuration .NET provider library supports updating configuration on demand
without causing an application to restart.
A: Request-driven configuration refresh
The configuration refresh is triggered by the incoming requests to your web app. No refresh will
occur if your app is idle. When your app is active, the App Configuration middleware monitors
the sentinel key, or any other keys you registered for refreshing in the ConfigureRefresh call.
The middleware is triggered upon every incoming request to your app. However, the middleware
will only send requests to check the value in App Configuration when the cache expiration time
you set has passed.
B, not C: The SetCacheExpiration method specifies the minimum time that must elapse before a
new request is made to App Configuration to check for any configuration changes. Default
expiration time is 30 seconds. Adjust to a higher value if you need to reduce the number of
requests made to your App Configuration store.

Answer 113

A

Answer: B, D, E

Gotta enable App Insights.
Always On can solve the performance issues.
Profiler can help find performance issues.
You can eliminate Premium upgrade because it says minimize costs, snapshot debugger is for debugging exceptions and has nothing to do with performance issues, restarting app impacts users and it says minimize impact.

Answer: B

Explanation:
- topics allows multiple subscribers, and here we need to process each event once
- correlation filter is for subscriptions, not topics
- even when assuming there is typo in the question and correlation filter is defined on the subscription level - it still is not a valid solution, because new stores can be opened in the future with many new device identifiers which you can’t know in advance. Besides that filter make no sense in this scenario whatsoever, you just need to save data in storage account and basically partition it by device identifier.

Answer 116

The first and second case are fairly straight forward to handle. Try to open the connection again. When you succeed, the transient error has been mitigated by the system. You can use your Azure Database for MySQL again. We recommend having waits before retrying the connection. Back off if the initial retries fail. This way the system can use all resources available to overcome the error situation. A good pattern to follow is:

Wait for 5 seconds before your first retry.
For each following retry, the increase the wait exponentially, up to 60 seconds.
Set a max number of retries at which point your application considers the operation failed.
