AWS Certified SysOps Administrator – Associate — Question 241

Accompany wants to monitor the number of Amazon EC2 instances that it is running. The company also wants to automate a service quota increase when the number of instances reaches a specific threshold.

Which solution meets these requirements?

Answer options

• A. Create an Amazon CloudWatch alarm to monitor Service Quotas. Configure the alarm to invoke an AWS Lambda function to request a quota increase when the alarm reaches the threshold.
• B. Create an AWS Config rule to monitor Service Quotas. Call an AWS Lambda function to remediate the action and increase the quota.
• C. Create an Amazon CloudWateh alarm to monitor the AWS Health Dashboard. Configure the alarm to invoke an AWS Lambda function to request a quota increase when the alarm reaches the threshold.
• D. Create an Amazon CloudWatch alarm to monitor AWS Trusted Advisor service quotas. Configure the alarm to publish a message to an Amazon Simple Notification Service (Amazon SNS) topic to increase the quota.

Correct answer: A

Explanation

Option A is correct because it directly sets up an Amazon CloudWatch alarm to monitor Service Quotas and uses an AWS Lambda function to automate the quota increase when the threshold is reached. Options B and C are incorrect as they do not specifically monitor Service Quotas and do not automate the quota increase in the manner described. Option D is also incorrect because it focuses on AWS Trusted Advisor rather than the necessary Service Quotas for EC2 instances.
