AWS Certified Solutions Architect Professional SAP-C02 Practice Question
A company operates 400 Amazon EC2 instances that run web and micro-services workloads across 12 AWS accounts in a single AWS Organizations structure. Leadership has asked the cloud center of excellence (CCoE) to create a rightsizing strategy that will reduce compute cost without compromising application performance.
The solution must:
- Base its recommendations on at least 90 days of historical utilization data.
- Allow architects to inspect projected CPU utilization for the recommended instance types before changes are applied.
- Produce a single, organization-wide report that is accessible from a central tooling account.
- Introduce as little ongoing operational overhead as possible and must not require installing additional software on the EC2 instances.
Which approach will meet these requirements MOST effectively?
Enable AWS Compute Optimizer for the organization, assign a delegated administrator account, activate the enhanced infrastructure metrics preference, and review the projected-utilization graphs or call the GetEC2RecommendationProjectedMetrics API to validate each recommendation.
Use AWS Cost Explorer rightsizing recommendations at the management account level. Export the recommendations as a CSV report each month and distribute it to member accounts.
Schedule an AWS Systems Manager Automation runbook that exports 90 days of CloudWatch metrics to Amazon S3 and uses a custom Python script in AWS Glue to generate rightsizing reports.
Configure detailed monitoring for all EC2 instances, install the unified CloudWatch agent to capture memory metrics, and export CloudWatch metric streams to Amazon S3 for analysis with Amazon Athena and Amazon QuickSight.
