AWS Certified SysOps Administrator – Associate — Question 82

A company uses AWS Organizations to manage its AWS accounts. A SysOps administrator must create a backup strategy for all Amazon EC2 instances across all the company’s AWS accounts.

Which solution will meet these requirements in the MOST operationally efficient way?

Answer options

• A. Deploy an AWS Lambda function to each account to run EC2 instance snapshots on a scheduled basis.
• B. Create an AWS CloudFormation stack set in the management account to add an AutoBackup=True tag to every EC2 instance.
• C. Use AWS Backup in the management account to deploy policies for all accounts and resources.
• D. Use a service control policy (SCP) to run EC2 instance snapshots on a scheduled basis in each account.

Correct answer: C

Explanation

The correct answer is C because AWS Backup provides a centralized way to manage backup policies across multiple accounts, ensuring efficiency and consistency. Options A and D involve manual processes that require management in each account, making them less efficient. Option B focuses on tagging, which does not directly implement a backup strategy.
