AWS Certified Developer – Associate (DVA-C02) — Question 440

A company generates SSL certificates from a third-party provider. The company imports the certificates into AWS Certificate Manager (ACM) to use with public web applications.

A developer must implement a solution to notify the company’s security team 90 days before an imported certificate expires. The company already has configured an Amazon Simple Queue Service (Amazon SQS) queue. The company also has configured an Amazon Simple Notification Service (Amazon SNS) topic that has the security team’s email address as a subscriber.

Which solution will provide the security team with the required notification about certificates?

Answer options

• A. Create an Amazon EventBridge rule that specifies the ACM Certificate Approaching Expiration event type. Set the SNS topic as the EventBridge rule’s target.
• B. Create an AWS Lambda function to search for all certificates that are expiring within 90 days. Program the Lambda function to send each identified certificate’s Amazon Resource Name (ARN) in a message to the SQS queue.
• C. Create an AWS Step Functions workflow that is invoked by each certificate’s expiration notification from AWS CloudTrail. Create an AWS Lambda function to send each certificate's Amazon Resource Name (ARN) in a message to the SQS queue.
• D. Configure AWS Config with the acm-certificate-expiration-check managed rule to run every 24 hours. Create an Amazon EventBridge rule that includes an event pattern that specifies the Config Rules Compliance Change detail type and the configured rule. Set the SNS topic as the EventBridge rule’s target.

Correct answer: A

Explanation

AWS Certificate Manager (ACM) natively integrates with Amazon EventBridge to emit 'ACM Certificate Approaching Expiration' events as certificates near their expiration date. By creating an EventBridge rule to detect this event type and setting the existing SNS topic as the target, the security team will automatically receive email notifications without the need for custom code. Other options involving AWS Config, Lambda, or Step Functions add unnecessary operational overhead and complexity.
