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 is using AWS CodeDeploy across a fleet of Amazon EC2 instances in an EC2 Auto Scaling group. The associated CodeDeploy deployment group, which is integrated with EC2 Auto Scaling, is configured to perform in-place deployments with codeDeployDefault.oneAtATime During an ongoing new deployment, the engineer discovers that, although the overall deployment finished successfully, two out of five instances have the previous application revision deployed. The other three instances have the newest application revision

What is likely causing this issue?

Options:

A.

The two affected instances failed to fetch the new deployment.

B.

A failed Afterinstall lifecycle event hook caused the CodeDeploy agent to roll back to the previous version on the affected instances

C.

The CodeDeploy agent was not installed in two affected instances.

D.

EC2 Auto Scaling launched two new instances while the new deployment had not yet finished, causing the previous version to be deployed on the affected instances.
