New Release DOP-C02 AWS Certified Professional Questions

To implement governance controls that restrict AWS service usage to within the United States and ensure alerts for any activity outside the governance policy, the following actions will meet the requirements:

A. Create an AWS Organizations SCP that denies access to all non-global services in non-US Regions. Attach the policy to the root of the organization. This action will effectively prevent users and roles in all accounts within the organization from accessing services in non-US Regions12.

B. Configure AWS CloudTrail to send logs to Amazon CloudWatch Logs and enable it for all Regions. Use a CloudWatch Logs metric filter to send an alert on any service activity in non-US Regions. This action will allow monitoring of all AWS Regions and will trigger alerts if any activity is detected in non-US Regions, ensuring that the governance team is notified as soon as possible3.

AWS Documentation on Service Control Policies (SCPs) and how they can be used to manage permissions and restrict access based on Regions12.

AWS Documentation on monitoring CloudTrail log files with Amazon CloudWatch Logs to set up alerts for specific activities3.

 Ensure that Amazon GuardDuty is Enabled:

Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior.

It can detect port scans and generate findings for these events.

 Create an Amazon CloudWatch Alarm for Detected EC2 and Port Scan Findings:

Configure GuardDuty to monitor for port scans and other threats.

Create a CloudWatch alarm that triggers when GuardDuty detects port scan activities.

 Connect the Alarm to the SNS Topic:

The CloudWatch alarm should be configured to send notifications to the SNS topic subscribed by the security team.

This setup ensures that the security team receives near-real-time notifications when a port scan is detected on the EC2 instances.

Example configuration steps:

Enable GuardDuty and ensure it is monitoring the relevant AWS accounts.

Create a CloudWatch alarm:

{

" AlarmName " : " GuardDutyPortScanAlarm " ,

" MetricName " : " ThreatIntelIndicator " ,

" Namespace " : " AWS/GuardDuty " ,

" Statistic " : " Sum " ,

" Dimensions " : [

{

" Name " : " FindingType " ,

" Value " : " Recon:EC2/Portscan "

}

],

" Period " : 300,

" EvaluationPeriods " : 1,

" Threshold " : 1,

" ComparisonOperator " : " GreaterThanOrEqualToThreshold " ,

" AlarmActions " : [ " arn:aws:sns:region:account-id:SecurityAlerts " ]

}

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.
