A company has deployed a critical application in two AWS Regions. The application uses an Application Load Balancer (ALB) in both Regions. The company has Amazon Route 53 alias DNS records for both ALBs. The company uses Amazon Route 53 Application Recovery Controller to ensure that the application can fail over between the two Regions. The Route 53 ARC configuration includes a routing control for both Regions. The company uses Route 53 ARC to perform quarterly disaster recovery (DR) tests. During the most recent DR test, a DevOps engineer accidentally turned off both routing controls. The company needs to ensure that at least one routing control is turned on at all times.

A DevOps learn has created a Custom Lambda rule in AWS Config. The rule monitors Amazon Elastic Container Repository (Amazon ECR) policy statements for ecr:' actions. When a noncompliant repository is detected, Amazon EventBridge uses Amazon Simple Notification Service (Amazon SNS) to route the notification to a security team.

When the custom AWS Config rule is evaluated, the AWS Lambda function fails to run.

Which solution will resolve the issue?

A.
Modify the Lambda function's resource policy to grant AWS Config permission to invoke the function.
Answers
A.
Modify the Lambda function's resource policy to grant AWS Config permission to invoke the function.
B.
Modify the SNS topic policy to include configuration changes for EventBridge to publish to the SNS topic.
Answers
B.
Modify the SNS topic policy to include configuration changes for EventBridge to publish to the SNS topic.
C.
Modify the Lambda function's execution role to include configuration changes for custom AWS Config rules.
Answers
C.
Modify the Lambda function's execution role to include configuration changes for custom AWS Config rules.
D.
Modify all the ECR repository policies to grant AWS Config access to the necessary ECR API actions.
Answers
D.
Modify all the ECR repository policies to grant AWS Config access to the necessary ECR API actions.
Suggested answer: A

Explanation:

Step 1: Understanding Lambda Permissions and AWS Config The custom AWS Config rule evaluates resources and invokes an AWS Lambda function when a compliance check is triggered. For AWS Config to invoke the Lambda function, it requires permission to do so. Issue: The Lambda function fails to execute because AWS Config doesn't have permission to invoke it. Action: Modify the resource-based policy of the Lambda function to grant AWS Config permission to invoke the Lambda function. Why: Without this permission, AWS Config cannot trigger the Lambda function, which is why the evaluation fails.

This corresponds to Option A: Modify the Lambda function's resource policy to grant AWS Config permission to invoke the function.
