Amazon AWS Certified DevOps Engineer - Professional Sample Questions (Q186-Q191):

NEW QUESTION # 186
A company runs an application in an Amazon Elastic Container Service (Amazon ECS) service that is associated with an Elastic Load Balancing (ELB) target group. A DevOps engineer updates the service to include a new task definition version. The DevOps engineer notices that the deployment does not finish running. New tasks enter a stopped state soon after the tasks launch. The task definition references an Amazon CloudWatch Logs log group.
Which issues are most likely the cause of the failing deployment? (Select TWO.)

• A. An essential container in the ECS task is exiting.
• B. The target group health check is failing, which causes Amazon ECS to stop the tasks.
• C. The CloudWatch Logs log group that is referenced in the task definition does not exist.
• D. The task role does not have the required permissions to launch the task.
• E. The IAM role that the DevOps engineer used to update the ECS service does not have the Amazon ECS RunTask permission.

Answer: A,B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract of DevOps Engineer documents only:
During an Amazon ECS service deployment, if tasks fail the Elastic Load Balancing target group health checks, Amazon ECS considers those tasks unhealthy and stops and replaces them. This behavior can cause the deployment to remain incomplete because healthy replacement tasks never become available.
Also, if an essential container in the task exits, the entire task stops. Since the question states that the new tasks enter a stopped state soon after launch, an essential container failure is a direct and highly likely cause.
Why the other options are incorrect:
B). The IAM role used by the DevOps engineer to update the ECS service does not need RunTask permission for the tasks to remain running after launch. A permission issue here would more likely affect the update action itself rather than cause launched tasks to stop shortly afterward.
C). Although CloudWatch Logs configuration problems can affect logging, the missing log group is not the most likely direct reason for ECS tasks to repeatedly stop in this deployment scenario.
D). The task role provides permissions to the application code running inside the container. It is not the role primarily responsible for launching the task. Task startup is typically related to the task execution role, ECS service behavior, container health, and load balancer checks.

NEW QUESTION # 187
A company has an AWS CodeDeploy application. The application has a deployment group that uses a single tag group to identify instances for the deployment of ApplicationA. The single tag group configuration identifies instances that have Environment=Production and Name=ApplicattonA tags for the deployment of ApplicationA.
The company launches an additional Amazon EC2 instance with Department=Marketing Environment
