Question 52 (Topic 1)

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?

○ 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).
○ 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).
○ 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.
○ 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.

Reference / correct answer:

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).

Most accepted answer: 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).

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. upvoted 1 times

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. upvoted 3 times

Question 53 (Topic 1)

A company migrated to AWS and uses AWS Business Support. The company wants to monitor the cost-effectiveness of Amazon EC2 instances across AWS accounts. The EC2 instances have tags for department, business unit, and environment. Development EC2 instances have high cost but low utilization. The company needs to detect and stop any underutilized development EC2 instances. Instances are underutilized if they had 10% or less average daily CPU utilization and 5 MB or less network I/O for at least 4 of the past 14 days. Which solution will meet these requirements with the LEAST operational overhead?

Select an option, then click Submit answer.

○ Configure Amazon CloudWatch dashboards to monitor EC2 instance utilization based on tags for department, business unit, and environment. Create an Amazon EventBridge rule that invokes an AWS Lambda function to stop underutilized development EC2 instances.
○ Configure AWS Systems Manager to track EC2 instance utilization and report underutilized instances to Amazon CloudWatch. Filter the CloudWatch data by tags for department, business unit, and environment. Create an Amazon EventBridge rule that invokes an AWS Lambda function to stop underutilized development EC2 instances.
○ Create an Amazon EventBridge rule to detect low utilization of EC2 instances reported by AWS Trusted Advisor. Configure the rule to invoke an AWS Lambda function that filters the data by tags for department, business unit, and environment and stops underutilized development EC2 instances.
○ Create an AWS Lambda function to run daily to retrieve utilization data for all EC2 instances. Save the data to an Amazon DynamoDB table. Create an Amazon QuickSight dashboard that uses the DynamoDB table as a data source to identify and stop underutilized development EC2 instances.

Reference / correct answer:

Create an Amazon EventBridge rule to detect low utilization of EC2 instances reported by AWS Trusted Advisor. Configure the rule to invoke an AWS Lambda function that filters the data by tags for department, business unit, and environment and stops underutilized development EC2 instances.

Most accepted answer: C. Create an Amazon EventBridge rule to detect low utilization of EC2 instances reported by AWS Trusted Advisor. Configure the rule to invoke an AWS Lambda function that filters the data by tags for department, business unit, and environment and stops underutilized development EC2 instances.

Selected Answer: C CloudWatch dashboards are for visual monitoring, not detection. upvoted 1 times

Selected Answer: C Due to the link posted by Kinnam and sam2ng, together with this https://docs.aws.amazon.com/awssupport/latest/user/cloudwatch-events-ta.html upvoted 1 times

Option C, This solution meets the requirements with the least operational overhead because it uses Amazon EventBridge (formerly CloudWatch Events) to trigger a response based on low utilization reports from AWS Trusted Advisor. AWS Trusted Advisor provides pre-configured dashboards that can be used to monitor various aspects of your AWS resources, including EC2 instance utilization. By leveraging these pre-configured dashboards, you don't need to set up additional monitoring infrastructure or write custom code. The EventBridge rule will automatically invoke the Lambda function when a low utilization report is received from Trusted Advisor, which eliminates the need for daily polling or manual intervention. The other options are more resource-intensive and require additional setup and maintenance: upvoted 1 times

Selected Answer: C AWS Trusted Advisor provides insights into underutilized EC2 instances automatically, including recommendations for cost-saving based on utilization metrics like CPU and network usage. Since the company is using AWS Business Support, they already have access to Trusted Advisor, making this a low-overhead solution. Amazon EventBridge can be used to create a rule that detects when Trusted Advisor reports low-utilization instances. This avoids the need for custom-built CloudWatch dashboards or manual tracking. AWS Lambda can be triggered to handle the logic of stopping instances that meet the specific criteria of low CPU utilization and network I/O, filtering by tags for department, business unit, and environment. Lambda is serverless and scales automatically, so it minimizes operational overhead. upvoted 4 times
