Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 519 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 519
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

A company is running a large containerized workload in the AWS Cloud. The workload consists of approximately 100 different services. The company uses Amazon Elastic Container Service (Amazon ECS) to orchestrate the workload.

Recently the company’s development team started using AWS Fargate instead of Amazon EC2 instances in the ECS cluster. In the past, the workload has come close to running the maximum number of EC2 instances that are available in the account.

The company is worried that the workload could reach the maximum number of ECS tasks that are allowed. A solutions architect must implement a solution that will notify the development team when Fargate reaches 80% of the maximum number of tasks.

What should the solutions architect do to meet this requirement?

  • A. Use Amazon CloudWatch to monitor the Sample Count statistic for each service in the ECS cluster. Set an alarm for when the math expression sample count/SERVICE_QUOTA(service)*100 is greater than 80. Notify the development team by using Amazon Simple Notification Service (Amazon SNS).
  • B. Use Amazon CloudWatch to monitor service quotas that are published under the AWS/Usage metric namespace. Set an alarm for when the math expression metric/SERVICE_QUOTA(metric)*100 is greater than 80. Notify the development team by using Amazon Simple Notification Service (Amazon SNS).
  • C. Create an AWS Lambda function to poll detailed metrics from the ECS cluster. When the number of running Fargate tasks is greater than 80, invoke Amazon Simple Email Service (Amazon SES) to notify the development team.
  • D. Create an AWS Config rule to evaluate whether the Fargate SERVICE_QUOTA is greater than 80. Use Amazon Simple Email Service (Amazon SES) to notify the development team when the AWS Config rule is not compliant.

Selected Answer: B
C and D are out due to using SES and not SNS for simple notification. Among A and B, A is out because CloudWatch alarm was set with SERVICE_QUOTA but the option choose to monitor sample count stats instead of service quota published.

Selected Answer: B
Why this is the correct choice: AWS/Usage metric namespace: This namespace provides detailed metrics for service usage and quotas, including the number of running ECS Fargate tasks. You can use this data to monitor how close you are to the service quotas. Service quota monitoring: The math expression metric/SERVICE_QUOTA(metric)*100 allows you to calculate the percentage of the quota being used, making it easy to set an alarm when usage reaches 80%. CloudWatch Alarm: This is a native and efficient way to monitor service usage, and you can easily configure notifications via Amazon SNS to alert the development team when the threshold is crossed.
