DOP-C02 Exam Dumps : AWS Certified DevOps Engineer - Professional

Enable AWS Config Across the Organization:

AWS Config provides a detailed view of the configuration of AWS resources in your AWS account. It can be used to assess, audit, and evaluate the configurations of your resources.

Enabling AWS Config across the organization ensures that all accounts are monitored for compliance.

Create a Conformance Pack Using the approved-amis-by-id AWS Config Managed Rule:

A conformance pack is a collection of AWS Config rules and remediation actions that can be easily deployed across an organization.

The approved-amis-by-id managed rule checks whether running instances are using approved AMIs.

Deploy the Conformance Pack Across the Organization:

Deploying the conformance pack across the organization ensures that all accounts adhere to the policy of using only approved AMIs.

The conformance pack can be deployed via the AWS Management Console, CLI, or SDKs.

Configure the Rule to Run the AWS-StopEC2Instance AWS Systems Manager Automation Runbook for Non-Compliant EC2 Instances:

The AWS-StopEC2Instance runbook can be configured to automatically stop any EC2 instances that are found to be non-compliant (i.e., not using approved AMIs).

This remediation action ensures that any unauthorized instances are promptly stopped, enforcing the policy without manual intervention.

By following these steps, the solution ensures that all EC2 instances across the organization use approved AMIs, and any non-compliant instances are remediated automatically.

The correct answer is C. Updating the SCP in the child OU to allow all actions for Amazon EC2 will enable the DevOps engineer to launch the EC2 instance in the vendor-data account. SCPs are applied to OUs and accounts in a hierarchical manner, meaning that the SCPs attached to the parent OU are inherited by the child OU and accounts. Therefore, the SCP in the child OU overrides the SCP in the root OU and denies all actions except for DynamoDB and Lambda. By adding EC2 to the allowed actions in the child OU’s SCP, the DevOps engineer can access EC2 resources in the vendor-data account.

Option A is incorrect because attaching the AmazonEC2FullAccess IAM policy to the IAM user will not grant the user access to EC2 resources. IAM policies are evaluated after SCPs, so even if the IAM policy allows EC2 actions, the SCP will still deny them.

Option B is incorrect because creating a new SCP that allows all actions for EC2 and attaching it to the vendor-data account will not work. SCPs are not cumulative, meaning that only one SCP is applied to an account at a time. The SCP attached to the account will be the SCP attached to the OU that contains the account. Therefore, option B will not change the SCP that is applied to the vendor-data account.

Option D is incorrect because creating a new SCP that allows all actions for EC2 and attaching it to the root OU will not work. As explained earlier, the SCP in the child OU overrides the SCP in the root OU and denies all actions except for DynamoDB and Lambda. Therefore, option D will not affect the SCP that is applied to the vendor-data account.

Comprehensive and Detailed Explanation From Exact Extract of DevOps Engineer documents only:

The correct answer is D because AWS Secrets Manager supports automatic secret rotation and provides built-in rotation templates for supported services, including Amazon ElastiCache for Redis OSS. This gives the least operational overhead for rotating the secret every 60 days.

The requirement also states that employees and applications must access secrets and parameters through AWS Systems Manager Parameter Store. Parameter Store can reference Secrets Manager secrets by using a reserved path, which allows the application to retrieve the secret through Parameter Store while the secret is actually stored and rotated in Secrets Manager.

Why the other options are incorrect:

A. This option correctly uses Secrets Manager rotation, but it does not specifically use the reserved Parameter Store reference path approach that satisfies the access requirement through Parameter Store as clearly as option D.

B. Parameter Store does not provide native automatic rotation for secrets in the same way that Secrets Manager does.

C. This option is possible, but it requires custom Lambda and EventBridge automation, which creates more operational overhead than using native Secrets Manager rotation with the provided template.
