CompTIA Linux+ (XK0-004) — Question 130

A systems administrator needs to conduct maintenance on a server.
Which of the following commands will place the administrator in the appropriate runlevel?

Answer options

• A. init 0
• B. telinit 1
• C. init 3
• D. telinit 6

Correct answer: A

Explanation

The correct command is 'init 0', which brings the system down to runlevel 0 for maintenance. The other options, such as 'telinit 1', 'init 3', and 'telinit 6', either change to a single-user mode, multi-user mode, or restart the system, which do not serve the purpose of maintenance mode.
