AWS Certified SysOps Administrator – Associate (legacy) — Question 156

A user is trying to pre-warm a blank EBS volume attached to a Linux instance. Which of the below mentioned steps should be performed by the user?

Answer options

• A. There is no need to pre-warm an EBS volume
• B. Contact AWS support to pre-warm
• C. Unmount the volume before pre-warming
• D. Format the device

Correct answer: C

Explanation

The correct answer is C because unmounting the volume is necessary to ensure that the pre-warming process can be executed without interference from any ongoing operations. Option A is incorrect because pre-warming can enhance performance, while B is wrong as AWS support does not handle pre-warming directly. Option D is also incorrect since formatting is not a required step in the pre-warming process.
