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

To restrict direct access to API Gateway, add a custom header in the CloudFront distribution origin request and use a Lambda authorizer in API Gateway to validate that header. Only requests routed through CloudFront will include this header. This is the AWS-recommended pattern in “Secure your APIs behind CloudFront using custom headers and Lambda authorizers.”

Configure the Systems Manager Document to Use the aws-downloadContent Plugin with a sourceType of GitHub and sourcelnfo with the Repository Details:

The aws-downloadContent plugin can download content from various sources, including GitHub, which is necessary for bootstrapping the laptops with the code stored in the GitHub repository.

schemaVersion: ' 2.2 '

description: " Download and run bootstrap script from GitHub "

mainSteps:

- action: aws:downloadContent

name: downloadBootstrapScript

inputs:

sourceType: GitHub

sourceInfo: ' { " owner " : " my-org " , " repository " : " my-repo " , " path " : " scripts/bootstrap.sh " , " getOptions " : " branch:main " } '

destinationPath: /tmp/bootstrap.sh

- action: aws:runShellScript

name: runBootstrapScript

inputs:

runCommand:

- chmod +x /tmp/bootstrap.sh

- /tmp/bootstrap.sh

This setup ensures that the bootstrap code is downloaded from GitHub and executed on the laptops using Systems Manager.

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

The correct answer is B because AWS Config can continuously evaluate the account-level S3 Block Public Access configuration by using a managed rule. When the configuration becomes noncompliant, AWS Config can trigger automatic remediation through an AWS Systems Manager Automation runbook to restore the required settings.

This solution directly satisfies both requirements:

Detect changes to account-level S3 public access settings.

Automatically revert those changes so that all public access is blocked again.

Why the other options are incorrect:

A. Security Hub is primarily for aggregated security findings and controls visibility. It is not the most direct or standard service for continuous configuration evaluation with automatic remediation of this specific setting.

C. An SCP can restrict permissions, but it does not automatically detect and revert changes to S3 Block Public Access settings.

D. Amazon Macie is for discovering and protecting sensitive data, not for continuously enforcing and remediating S3 Block Public Access account settings.
