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.)
To meet the requirements of optimizing costs using AWS Trusted Advisor, the company's finance team should first use the Trusted Advisor recommendations in the management account. This is because the finance team has access to the management account, where central insights across all member accounts can be obtained. Additionally, the finance team should review the Trusted Advisor checks for Amazon RDS Reserved Instance Optimization. Since the RDS instances are running in On-Demand mode, checking for Reserved Instance Optimization can provide actionable recommendations for cost savings by switching from On-Demand to Reserved Instances where applicable.
I THINK IT'S C,D

AnswerAC We have On-Demand instances of RDS. If DB is used very often then it can occur that using Reserved Instrance can bring some $$ savings. It is mentioned in AWS docs :) https://docs.aws.amazon.com/awssupport/latest/user/cost-optimization-checks.html#amazon-ec2-reserved-instances-optimization
Instances are running On-Demand, they need to check to see if they can save money by switching the reserved instances from on-demand An important part of using AWS involves balancing your Reserved Instance (RI) purchase against your On-Demand Instance usage. This check provides recommendations on which RIs will help reduce the costs incurred from using On-Demand Instances.

Cost Optimization: By providing actionable recommendations, Trusted Advisor assists you in identifying areas of overspending and underutilization, like idle RDS DB instances or underused EBS volumes, leading to significant cost savings.
Please check with question 308. It should run in management account and review the Trusted Advisor check for Amazon RDS Idle DB Instances.
I correct myself the answer should be AC as the DB can be switch to on-demand rather than reserved and it would save save the cost.
Option A,E
i dont think AWS Compute Optimizer work with RDS
use Trusted advisor on management account
