AWS Certified Cloud Practitioner — Question 416

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 the most operationally efficient method because it is a native, built-in AWS feature designed to capture point-in-time backups of an EBS volume with minimal administrative effort. In contrast, copying data to another volume, transfering files to an on-premises server, or writing custom scripts to sync to Amazon S3 introduce unnecessary complexity, operational overhead, and potential performance impacts.
