AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A development team manually builds an artifact locally and then places it in an Amazon S3 bucket. The application has a local cache that must be cleared when a deployment occurs. The team runs a command to do this downloads the artifact from Amazon S3 and unzips the artifact to complete the deployment.

A DevOps team wants to migrate to a CI/CD process and build in checks to stop and roll back the deployment when a failure occurs. This requires the team to track the progression of the deployment.

Which combination of actions will accomplish this? (Select THREE)

Options:

A.

Allow developers to check the code into a code repository Using Amazon EventBridge on every pull into the mam branch invoke an AWS Lambda function to build the artifact and store it in Amazon S3.

B.

Create a custom script to clear the cache Specify the script in the Beforelnstall lifecycle hook in the AppSpec file.

C.

Create user data for each Amazon EC2 instance that contains the clear cache script Once deployed test the application If it is not successful deploy it again.

D.

Set up AWS CodePipeline to deploy the application Allow developers to check the code into a code repository as a source tor the pipeline.

E.

Use AWS CodeBuild to build the artifact and place it in Amazon S3 Use AWS CodeDeploy to deploy the artifact to Amazon EC2 instances.

F.

Use AWS Systems Manager to fetch the artifact from Amazon S3 and deploy it to all the instances.

Question 2

A company has an organization in AWS Organizations with many OUs that contain many AWS accounts. The organization has a dedicated delegated administrator AWS account.

The company needs the accounts in one OU to have server-side encryption enforced for all Amazon Elastic Block Store (Amazon EBS) volumes and Amazon Simple Queue Service (Amazon SQS) queues that are created or updated on an AWS CloudFormation stack.

Which solution will enforce this policy before a CloudFormation stack operation in the accounts of this OU?

Options:

A.

Activate trusted access to CloudFormation StackSets. Create a CloudFormation Hook that enforces server-side encryption on EBS volumes and SQS queues. Deploy the Hook across the accounts in the OU by using StackSets.

B.

Set up AWS Config in all the accounts in the OU. Use AWS Systems Manager to deploy AWS Config rules that enforce server-side encryption for EBS volumes and SQS queues across the accounts in the OU.

C.

Write an SCP to deny the creation of EBS volumes and SQS queues unless the EBS volumes and SQS queues have server-side encryption. Attach the SCP to the OU.

D.

Create an AWS Lambda function in the delegated administrator account that checks whether server-side encryption is enforced for EBS volumes and SQS queues. Create an IAM role to provide the Lambda function access to the accounts in the OU.

Question 3

A company has an application that is using a MySQL-compatible Amazon Aurora Multi-AZ DB cluster as the database. A cross-Region read replica has been created for disaster recovery purposes. A DevOps engineer wants to automate the promotion of the replica so it becomes the primary database instance in the event of a failure.

Which solution will accomplish this?

Options:

A.

Configure a latency-based Amazon Route 53 CNAME with health checks so it points to both the primary and replica endpoints. Subscribe an Amazon SNS topic to Amazon RDS failure notifications from AWS CloudTrail and use that topic to invoke an AWS Lambda function that will promote the replica instance as the primary.

B.

Create an Aurora custom endpoint to point to the primary database instance. Configure the application to use this endpoint. Configure AWS CloudTrail to run an AWS Lambda function to promote the replica instance and modify the custom endpoint to point to the newly promoted instance.

C.

Create an AWS Lambda function to modify the application ' s AWS CloudFormation template to promote the replica, apply the template to update the stack, and point the application to the newly promoted instance. Create an Amazon CloudWatch alarm to invoke this Lambda function after the failure event occurs.

D.

Store the Aurora endpoint in AWS Systems Manager Parameter Store. Create an Amazon EventBridge event that detects the database failure and runs an AWS Lambda function to promote the replica instance and update the endpoint URL stored in AWS Systems Manager Parameter Store. Code the application to reload the endpoint from Parameter Store if a database connection fails.
