QUESTION 22
Which configuration file should be modified to disable the ctrl-alt-delete key combination?

A. /etc/keys
B. /proc/keys
C. /etc/inittab
D. /proc/inittab
E. /etc/reboot

Correct Answer: C
Section: Part 9
Explanation

Explanation/Reference:
In Linux, this keystroke combination is recognized by the keyboard device driver in the kernel. In the absence of
more specific instructions, which will usually only be during system initialization, the kernel directly initiates a
soft reboot in response. More commonly, the kernel will send a signal to the init process, which will perform an
administrator-configured task, such as running a script, or displaying an "end current session" box in KDE.
However, Linux systems can be configured to ignore the keystroke combination. The setting is usually in the
inittab(5) configuration file under the keyword "ca".

In newer Linux systems (using upstart) /etc/inittab is replaced by /etc/event.d/

QUESTION 23
