[LPIC-1]Linux Filesystems 5

What does the command mount -a do?

A. It ensures that all file systems listed with the option noauto in /etc/fstab are mounted.
B. It shows all mounted file systems that have been automatically mounted.
C. It opens an editor with root privileges and loads /etc/fstab for editing.
D. It ensures that all file systems listed with the option auto in /etc/fstab are mounted.
E. It ensures that all file systems listed in /etc/fstab are mounted regardless of their options.

題解

「mount」指令用來掛載檔案系統,「-a」參數可以掛載「fstab」(/etc/fstab)內所有使用「auto」選項的檔案系統。所以答案是選項D。
