Amazon Web Services DOP-C02 Exam With Confidence Using Practice Dumps

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.

Activate AWS Control Tower Guardrail:

Use AWS Control Tower to activate a detective guardrail that checks whether RDS storage is encrypted.

Create SNS Topic for Notifications:

Set up an Amazon Simple Notification Service (SNS) topic in the audit account to receive notifications about non-compliant databases.

Create EventBridge Rule to Filter Non-compliant Events:

Create an Amazon EventBridge rule that filters events related to the guardrail ' s findings on non-compliant RDS instances.

Configure the rule to send notifications to the SNS topic when non-compliant events are detected.

Subscribe Security Engineer ' s Email to SNS Topic:

Subscribe the security engineer ' s email address to the SNS topic to receive notifications when non-compliant databases are detected.

By using AWS Control Tower to activate a detective guardrail and setting up SNS notifications for non-compliant events, the company can efficiently monitor and ensure that all RDS databases are encrypted at rest.

The following are the steps that the DevOps engineer should take to ensure that all EBS volumes always have the Backup_Frequency tag so that the company can perform backups at least weekly unless a different value is specified:

Set up AWS Config in the account.

Use a managed rule that returns a compliance failure for EC2::Volume resources that do not have a Backup Frequency tag applied.

Configure a remediation action that uses a custom AWS Systems Manager Automation runbook to apply the Backup_Frequency tag with a value of weekly.

The managed rule AWS::Config::EBSVolumesWithoutBackupTag will return a compliance failure for any EBS volume that does not have the Backup_Frequency tag applied. The remediation action will then use the Systems Manager Automation runbook to apply the Backup_Frequency tag with a value of weekly to the EBS volume.
