AWS Certified Solutions Architect – Associate (SAA-C03) — Question 800

A company runs several Amazon RDS for Oracle On-Demand DB instances that have high utilization. The RDS DB instances run in member accounts that are in an organization in AWS Organizations.

The company's finance team has access to the organization's management account and member accounts. The finance team wants to find ways to optimize costs by using AWS Trusted Advisor.

Which combination of steps will meet these requirements? (Choose two.)

Answer options

• A. Use the Trusted Advisor recommendations in the management account.
• B. Use the Trusted Advisor recommendations in the member accounts where the RDS DB instances are running.
• C. Review the Trusted Advisor checks for Amazon RDS Reserved Instance Optimization.
• D. Review the Trusted Advisor checks for Amazon RDS Idle DB Instances.
• E. Review the Trusted Advisor checks for compute optimization. Crosscheck the results by using AWS Compute Optimizer.

Correct answer: A, C

Explanation

Because the Amazon RDS instances have high utilization, they are running continuously and are ideal candidates for Reserved Instances, making the Amazon RDS Reserved Instance Optimization check the correct focus. To get an organization-wide view of these cost savings, the recommendations must be viewed from the management account, as member accounts do not have the consolidated billing context needed for organization-wide Reserved Instance recommendations. Checking for idle DB instances is incorrect because the prompt specifies the instances have high utilization.
