What is Azure CDN
A content delivery network (CDN) is a distributed network of servers that can efficiently deliver web content to users. CDNs store cached content on edge servers in point-of-presence (POP) locations that are close to end users, to minimize latency.
Which pricing options are best for “maximum performance” for dynamic content with minimal latency and cost?
Pricing Tier: Standard
Profile: Akamai instead of Microsoft, Alternative Verizon
Optimization: dynamic site acceleration
Which pricing tier is best for an Azure Web App if costs should be low, but the Azure resources should run in an isolated network
Isolated
What does Isolated mean in Azure VMs
They run in a private area of Azure and are therefore ideal for connections to on-premises services.
You develop app that uses Azure Blob storage. App must read the transaction logs of all the changes that occur to the blobs and the blob metadata in the storage account for auditing. The changes must be in order in which they occured, include only create, update, delete, and copy operations and be retained for compliance reasons.
You need to process the transaction logs asynchronously. What should you do?
a) Process all Azure Blob Storage events by using azure event grid with a subscriber azure function app
b) Enable the change feed on the storage account and process all changes for available events
c) Process all Azure Storage Analytics logs for successfull blob events
d) Use Azure Monitor HPP Data Collector Api and scan the request body for successful blob events
b)
True or False? General-purpose V2 account type for Azure Blob Storage is well suited for apps that need to modify media data in less then one minute when using a azure function triggered by blob storage upload
True
In Azure Cosmos DB, what is a composite Index
Queries that have an ORDER BY clause with two or more properties require a composite index. You can also define a composite index to improve the performance of many equality and range queries. By default, no composite indexes are defined so you should add composite indexes as needed.

When reacting to events that occur over 1 million times within an hour, what is the best azure technique?
a) Azure Storage Queue
b) Azure Event hub
c) Azure Service Bus topic
d) Azure Event Grid Topic
b) Event Hub
Azure Event Hubs is a big data streaming platform and event ingestion service. It can receive and process millions of events per second
