AWS Certified DevOps Engineer – Professional (DOP-C02) — Question 157

A company has multiple development groups working in a single shared AWS account. The senior manager of the groups wants to be alerted via a third-party API call when the creation of resources approaches the service limits for the account.

Which solution will accomplish this with the LEAST amount of development effort?

Answer options

• A. Create an Amazon EventBridge rule that runs periodically and targets an AWS Lambda function. Within the Lambda function, evaluate the current state of the AWS environment and compare deployed resource values to resource limits on the account. Notify the senior manager if the account is approaching a service limit.
• B. Deploy an AWS Lambda function that refreshes AWS Trusted Advisor checks, and configure an Amazon EventBridge rule to run the Lambda function periodically. Create another EventBridge rule with an event pattern matching Trusted Advisor events and a target Lambda function. In the target Lambda function, notify the senior manager.
• C. Deploy an AWS Lambda function that refreshes AWS Health Dashboard checks, and configure an Amazon EventBridge rule to run the Lambda function periodically. Create another EventBridge rule with an event pattern matching Health Dashboard events and a target Lambda function. In the target Lambda function, notify the senior manager.
• D. Add an AWS Config custom rule that runs periodically, checks the AWS service limit status, and streams notifications to an Amazon Simple Notification Service (Amazon SNS) topic. Deploy an AWS Lambda function that notifies the senior manager, and subscribe the Lambda function to the SNS topic.

Correct answer: B

Explanation

Option B is the best choice as it directly utilizes AWS Trusted Advisor checks, which specifically monitor service limits, and it leverages EventBridge for event-driven notifications with minimal development overhead. The other options either involve more complex setups or use services that do not align as closely with the requirement to monitor service limits effectively.
