Linux Essentials (010-160) — Question 24

Which of the following directories must be mounted with read and write access if it resides on its own dedicated file system?

Answer options

• A. /opt
• B. /lib
• C. /etc
• D. /var
• E. /usr

Correct answer: D

Explanation

/var is the directory that typically requires read and write access as it stores variable data like logs, databases, and spool files. In contrast, /lib, /etc, /usr, and /opt are generally mounted with read-only access since they contain system binaries and configuration files that do not change frequently.
