Question 59 of 75 | ← Chapter 3

Q284. A company runs many workloads on AWS and uses AWS Organizations to manage its accounts. The workloads are hosted on Amazon EC2,AWS Fargate, and AWS Lambda. Some of the workloads have unpredictable demand. Accounts record high usage in some months and low usage in other months. The company wants to optimize its compute costs over the next 3 years.A solutions architect obtains a 6- month average for each of the accounts across the organization to calculate usage. Which solution will provide the MOST cost savings for all the organization's compute usage?

• A. Purchase Reserved Instances for the organization to match the size and number of the most common EC2 instances from the member accounts.
• B. Purchase a Compute Savings Plan for the organization from the management account by using the recommendation at the management account level. ✓
• C. Purchase Reserved Instances for each member account that had high EC2 usage according to the data from the last 6 months.
• D. Purchase an EC2 Instance Savings Plan for each member account from the management account based on EC2 usage data from the last 6 months.

Correct Answer: B. Purchase a Compute Savings Plan for the organization from the management account by using the recommendation at the management account level.

Explanation

A Compute Savings Plan provides flexibility and cost savings for EC2, Fargate, and Lambda usage in exchange for a commitment to use a specific amount of compute power (measured in dollars per hour) over a one- or three-year term. Compute Savings Plans apply automatically to any running instance that matches the attributes of the plan, regardless of whether they are used by EC2, Fargate, or Lambda. The Compute Savings Plan can be purchased by using the recommendation at the management account level, which will cover all member accounts across the organization. This option provides maximum flexibility and cost savings for all the organization's compute usage. Option A involves purchasing Reserved Instances for the organization to match the size and number of the most common EC2 instances from the member accounts. This option may not provide optimal cost savings as it does not consider the workload patterns of other services like Fargate and Lambda. Option C involves purchasing Reserved Instances for each member account that had high EC2 usage according to the data from the last 6 months. This option may not provide optimal cost savings as it only considers one service (EC2) and does not account for workload patterns of other services like Fargate and Lambda. Option D involves purchasing an EC2 Instance Savings Plan for each member account from the management account based on EC2 usage data from the last 6 months. While this option may provide cost savings for EC2 instances, it does not consider the workload patterns of other services like Fargate and Lambda. centralized management of multi-account environments.
