Which combination of steps will meet these requirements?
(Choose two.)
Use the Trusted Advisor recommendations in the management account.
Use the Trusted Advisor recommendations in the member accounts where the RDS DB instances are running.
Review the Trusted Advisor checks for Amazon RDS Reserved Instance Optimization.
Review the Trusted Advisor checks for Amazon RDS Idle DB Instances.
Review the Trusted Advisor checks for compute optimization. Crosscheck the results by using AWS Compute Optimizer.
Explanations:
The Trusted Advisor recommendations in the management account can provide a consolidated view of all accounts in the AWS Organization, including the member accounts where the RDS DB instances are running.
Trusted Advisor recommendations are only available in the individual member accounts, not the management account, unless the management account has explicit access to those accounts’ Trusted Advisor checks.
The Amazon RDS Reserved Instance Optimization check in Trusted Advisor helps identify opportunities for cost optimization by recommending Reserved Instances based on usage patterns, which is relevant for high-utilization DB instances.
The Amazon RDS Idle DB Instances check does not apply to high-utilization instances. This check is intended to identify underutilized or idle instances, which is not the case here.
The compute optimization checks are related to EC2 instances and not relevant to RDS DB instances. AWS Compute Optimizer focuses on EC2 instances, not RDS instances.
I judge that the answer is:
Use the Trusted Advisor recommendations in the management account.
