AWS Certified SysOps Administrator – Associate (legacy) — Question 668

A company has an application that is hosted on two Amazon EC2 instances in different Availability Zones. Both instances contain data that is critical for the company's business. Backups need to be retained for 7 days and need to be updated every 12 hours.
Which solution will meet these requirements with the LEAST amount of effort?

Answer options

• A. Use an Amazon EventBridge (Amazon CloudWatch Events) scheduled rule to create snapshots of the Amazon Elastic Block Store (Amazon EBS) volumes.
• B. Use Amazon Data Lifecycle Manager (Amazon DLM) to create a snapshot lifecycle policy for both instances.
• C. Create a batch job to generate automated snapshots of the Amazon Elastic Block Store (Amazon EBS) volumes.
• D. Create an AWS Lambda function to copy the data to Amazon S3 Glacier.

Correct answer: A

Explanation

Amazon EventBridge (Amazon CloudWatch Events) scheduled rules allow you to automate tasks on a regular schedule, such as triggering EBS snapshots every 12 hours to ensure business continuity. This serverless approach requires minimal setup to target the specific Amazon EBS volumes of both EC2 instances. Other options, such as writing custom batch jobs or Lambda functions to copy data to Amazon S3 Glacier, demand significantly more development and maintenance effort.
