AWS Certified Cloud Practitioner (CLF-C02) — Question 597

A user needs to perform a one-time backup of an Amazon Elastic Block Store (Amazon EBS) volume that is attached to an Amazon EC2 instance.

What is the MOST operationally efficient way to perform this backup?

Answer options

• A. Attach another EBS volume to the EC2 instance, and copy the contents.
• B. Copy the EBS volume to a server that is running outside AWS and is connected with AWS Direct Connect.
• C. Create an EBS snapshot of the volume.
• D. Create a custom script to copy the EBS file contents to Amazon S3.

Correct answer: C

Explanation

Creating an EBS snapshot is a native AWS feature designed specifically for point-in-time backups of EBS volumes, making it the most operationally efficient method with minimal effort. Other options, such as copying files to another volume, transferring data on-premises via AWS Direct Connect, or writing custom scripts for Amazon S3 uploads, introduce unnecessary complexity, manual labor, and infrastructure overhead.
