Question 400
An administrator needs temporary working memory for active processes, not permanent file storage. One student proposes Add or assess system RAM capacity and another proposes Run lsblk to inspect block devices. Which technical comparison is the soundest?
Explanation
Correct Answer
Correct distinction: Add or assess system RAM capacity targets RAM volatile working memory; RAM stores actively used data and is typically volatile when power is removed. The compared alternative instead serves block device inventory.
Incorrect Answers
Incorrect mapping: Run lsblk to inspect block devices is used for block device inventory. It does not displace Add or assess system RAM capacity for the described requirement.
The mechanisms are different: RAM stores actively used data and is typically volatile when power is removed. By contrast, lsblk displays block-device and partition relationships. They are not universally interchangeable.
The third option addresses device driver compatibility: A device driver allows the kernel to control supported hardware interfaces. The original action remains relevant because RAM stores actively used data and is typically volatile when power is removed.
