Question
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?
Options
- ACreate an Amazon EventBridge rule that runs periodically and targets an AWS Lambda function.
- BDeploy an AWS Lambda function that refreshes AWS Trusted Advisor checks, and configure an
- CDeploy an AWS Lambda function that refreshes AWS Health Dashboard checks, and configure
- DAdd an AWS Config custom rule that runs periodically, checks the AWS service limit status, and
Explanation
Explanation
Option B is correct because AWS Trusted Advisor natively monitors service limits and provides built-in checks for over 50 service limits across your AWS account. By creating a Lambda function that refreshes Trusted Advisor checks and then triggers a third-party API call (via Amazon SNS or EventBridge) when limits are approached, you leverage existing AWS functionality with minimal custom development - making it the least-effort solution.
Why the distractors are wrong:
- Option A (EventBridge + Lambda alone) is too vague and would require significant custom code to query and evaluate service limits from scratch, increasing development effort.
- Option C (AWS Health Dashboard) is designed to notify you of AWS service disruptions and scheduled maintenance affecting your account, not for proactively tracking resource usage against service limits.
- Option D (AWS Config custom rule) would require writing and maintaining custom logic to check service limits, which involves considerably more development effort than leveraging Trusted Advisor's pre-built limit checks.
Memory Tip 🧠
Think "Trusted Advisor = Trusted Limit Watcher" - whenever an exam question mentions monitoring service limits with minimal effort, Trusted Advisor is almost always the right tool, since it already has this functionality built in and ready to use.
