Practice 4 Flashcards
CloudTrail logs provide you with
detailed API tracking for Amazon S3 bucket-level and object-level operations
server access logs for Amazon S3 provide you
visibility into object-level operations on your data in Amazon S3 (referrer, turnaround time)
s3 hosted style format
http://bucket.s3.amazonaws.com
s3 path style format
http://s2.amazonaws.com/bucket
AWS Batch
is primarily used to efficiently run hundreds of thousands of batch computing jobs in AWS
cluster endpoint
connects to the current primary DB instance for a DB cluster (only one that can do writer operations)
each aurora db cluster has one cluster endpoint and one primary db instance - T or F
true
reader endpoint
connects to one of the available aurora replicas for that db cluster (each aurora db has one reader end point)
custom endpoint
represent a set of DB instances that you choose
instance endpoint
connects to specifc DB instance within an Aurora Cluster (to diagnose capacity or performance issues that affect one specific instance in an Aurora Cluster)
Amazon Resource Names (ARNs)
uniquely identify AWS resources
AWS Resource ID is primarily used to
find your resources in the Amazon EC2 console only and not your entire VPC or AWS accoun
AWS Service Namespaces only helps you
identify an AWS service and not a unique resource (for amazon S3 - it’s s3)
Calculation for the IOPS
50 * GiB (volume) = IOPS
ex: given a 10 GiB volume = 50 * 10GiB = 500 IOPS
You only need one public subnet per Availability Zone - T or F
true
DynamoDB auto scaling uses the ? to dynamically adjust provisioned throughput capacity on your behalf, in response to actual traffic patterns.
AWS Application Auto Scaling service
Enable Cross-Region Snapshots Copy in your Amazon Redshift Cluste
copy snapshots for a cluster to another region
Aurora is compatible with 2 dbs
Mysql and postgreSqL
DynamoDB is compatible with ? DB
NOSQL
Data pipeline is primarily used as
a cloud-based data workflow service that helps you process and move data between different AWS services and on-premises data sources.
AWS services to build a fault-tolerant and highly available architecture?
EC2 and ELB
Lambda@Edge is a
feature of Amazon CloudFront that lets you run code closer to users of your application, which improves performance and reduces latency.
Route 53 does not have any computing capability. - t or f
true
enhanced monitoring metrics that Amazon CloudWatch gathers from Amazon RDS DB instances
- RDS child processes - summary of the RDS processes that support the DB instance
- RDS processes - summary of the resources used by the RDS management agent, diagnostics monitoring processes, and other AWS processes that are required to support RDS DB instances
- OS processes - summary of the kernel and system processes, which generally have minimal impact on performance
Where can you safely import the SSL/TLS certificate of your application?
- AWS Certificate Manager (ACM)
2. IAM Certificate Store
AWS X-Ray
used to to trace and analyze user requests as they travel through your Amazon API Gateway APIs to the underlying services.
CloudWatch returns ? if the check fails
impaired
Cloudwatch status insufficient-data means
checks may still be in progress on the volume
Cloudwatch status - warning
degraded/severely degraded (volume performance is below/well below expectations)
if identity store which is currently being used is not compatible with SAML - what can be done
If your identity store is not compatible with SAML 2.0, then you can :
- build a custom identity broker application to perform a similar function.
- The broker application authenticates users, requests temporary credentials for users from AWS, and then provides them to the user to access AWS resources.
Amazon EBS can deliver performance for workloads that require thelowest-latency access to datafrom a single EC2 instance - true or false
true
the new EC2 instance does not automatically get a DNS hostname because theDNS resolutionandDNS hostnamesattributes are disabled in the newly created VPC (non default vpc) - t or f
true
Proxy Protocol is an
Internet protocol used to carry connection information from the source requesting the connection to the destination for which the connection was requested
Connection Draining
ELB configuration - To ensure that a Classic Load Balancer stops sending requests to instances that are de-registering or unhealthy while keeping the existing connections open, we use this
