AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A DevOps engineer is planning to deploy a Ruby-based application to production. The application needs to interact with an Amazon RDS for MySQL database and should have automatic scaling and high availability. The stored data in the database is critical and should persist regardless of the state of the application stack.

The DevOps engineer needs to set up an automated deployment strategy for the application with automatic rollbacks. The solution also must alert the application team when a deployment fails.

Which combination of steps will meet these requirements? (Select THREE.)

Options:

A.

Deploy the application on AWS Elastic Beanstalk. Deploy an Amazon RDS for MySQL DB instance as part of the Elastic Beanstalk configuration.

B.

Deploy the application on AWS Elastic Beanstalk. Deploy a separate Amazon RDS for MySQL DB instance outside of Elastic Beanstalk.

C.

Configure a notification email address that alerts the application team in the AWS Elastic Beanstalk configuration.

D.

Configure an Amazon EventBridge rule to monitor AWS Health events. Use an Amazon Simple Notification Service (Amazon SNS) topic as a target to alert the application team.

E.

Use the immutable deployment method to deploy new application versions.

F.

Use the rolling deployment method to deploy new application versions.

Question 2

A company is migrating an application to Amazon Elastic Container Service (Amazon ECS). The company wants to consolidate log data in Amazon CloudWatch in the us-west-2 Region. No CloudWatch log groups currently exist for Amazon ECS.

The company receives the following error code when an ECS task attempts to launch:

“service my-service-name was unable to place a task because no container instance met all of its requirements.”

The ECS task definition includes the following container log configuration:

"logConfiguration": {

"logDriver": "awslogs",

"options": {

"awslogs-create-group": "true",

"awslogs-group": "awslogs-mytask",

"awslogs-region": "us-west-2",

"awslogs-stream-prefix": "awslogs-mytask",

"mode": "non-blocking",

"max-buffer-size": "25m"

}

}

The ECS cluster uses an Amazon EC2 Auto Scaling group to provide capacity for tasks. EC2 instances launch an Amazon ECS-optimized AMI.

Which solution will fix the problem?

Options:

A.

Modify the ECS infrastructure IAM role to add the logs:CreateLogStream and logs:PutLogEvents permissions.

B.

Modify the ECS log configuration to use blocking mode.

C.

Modify the ECS container instance IAM role to add the logs:CreateLogStream and logs:PutLogEvents permissions.

D.

Modify the ECS log configuration by setting the awslogs-create-group option to false.

Question 3

A DevOps engineer manages an AWS CodePipeline pipeline that builds and deploys a web application on AWS. The pipeline has a source stage, a build stage, and a deploy stage. When deployed properly, the web application responds with a 200 OK HTTP response code when the URL of the home page is requested. The home page recently returned a 503 HTTP response code after CodePipeline deployed the application. The DevOps engineer needs to add an automated test into the pipeline. The automated test must ensure that the application returns a 200 OK HTTP response code after the application is deployed. The pipeline must fail if the response code is not present during the test. The DevOps engineer has added a CheckURL stage after the deploy stage in the pipeline. What should the DevOps engineer do next to implement the automated test?

Options:

A.

Configure the CheckURL stage to use an Amazon CloudWatch action. Configure the action to use a canary synthetic monitoring check on the application URL and to report a success or failure to CodePipeline.

B.

Create an AWS Lambda function to check the response code status of the URL and to report a success or failure to CodePipeline. Configure an action in the CheckURL stage to invoke the Lambda function.

C.

Configure the CheckURL stage to use an AWS CodeDeploy action. Configure the action with an input artifact that is the URL of the application and to report a success or failure to CodePipeline.

D.

Deploy an Amazon API Gateway HTTP API that checks the response code status of the URL and that reports success or failure to CodePipeline. Configure the CheckURL stage to use the AWS Device Farm test action and to provide the API Gateway HTTP API as an input artifact.
