Comprehensive and Detailed Explanation From Exact Extract:

The requirement is to prevent any product files containing unannounced product IDs (prefixed with a specific UUID) from being stored in the production S3 bucket that users can access.

To achieve this, a best practice is to use a staging bucket as a control point before files go to production, combined with Amazon Macie’s data classification capabilities.

Creating a custom data identifier in Amazon Macie allows precise detection of product IDs starting with the specific UUID, which default managed identifiers will not detect.

By running a Macie sensitive data discovery job on the staging bucket, you can identify files containing these sensitive product IDs.

Only files without findings (i.e., files that do not contain unannounced product IDs) are copied to the production bucket, ensuring no sensitive information is exposed.This approach aligns with AWS best practices for data classification and staged deployment workflows, maximizing control and reducing risk.Using Macie on the production bucket directly (options B and D) risks exposing sensitive data before detection and deletion. Option C uses managed data identifiers, which will likely not detect the custom UUID prefix pattern.

Step 1: Reacting to CloudFormation Stack Events with EventBridgeAWS CloudFormation emits events during the lifecycle of a stack, including the UPDATE_COMPLETE event after a successful stack update. You can use Amazon EventBridge to detect this event and trigger a specific action (such as invoking a Lambda function).

Action: Create an EventBridge rule that listens for the UPDATE_COMPLETE event for the CloudFormation stack.

Why: EventBridge allows you to automatically detect CloudFormation stack lifecycle events and take action based on them.

Step 2: Invoking the Lambda FunctionAfter the EventBridge rule detects the UPDATE_COMPLETE event, it can invoke the pre-configured Lambda function to apply or update the tag on the specific CloudFormation stack instance.

Action: Configure the EventBridge rule to invoke the Lambda function when the UPDATE_COMPLETE event occurs.

Why: This automation ensures that the tag is applied immediately after a successful stack update without any manual intervention.

Amazon ECR supports enhanced scanning powered by Amazon Inspector, which provides deeper security scanning for container images including OS and programming language package vulnerabilities.

Enabling enhanced scanning (Option B) allows detection of CRITICAL and HIGH vulnerabilities.

Amazon ECR emits scan completion events via EventBridge, which can trigger Lambda functions. The Lambda function can process the scan results from Amazon Inspector and programmatically approve or reject the image in the CI/CD pipeline (Option D).

Basic scanning (Option A) is limited and does not integrate with Inspector.

Options C and E describe functionalities not natively supported (ECR does not automatically submit Rejected status; Clair is not used in AWS ECR scanning).

To restore the functionality of the Auto Scaling group after the AMI was deleted, the DevOps engineer needs to create a new AMI and update the Auto Scaling group to use it. The DevOps engineer can create a new AMI by copying the most recent public AMI of the operating system that the EC2 instances use. This will ensure that the new AMI has the same operating system as the custom AMI that was deleted. The DevOps engineer can then create a new launch template that uses the new AMI and update the Auto Scaling group to use the new launch template. This will allow the Auto Scaling group to launch new instances with the new AMI.
