Objective 1.1

XK0-005

Summarize Linux fundamentals.

Objective 1.1 sits in System Management, which carries 32% of the Linux+ exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

1-1System Management

An administrator must change a daemon's machine-local settings on one server without touching its binaries. Which directory holds that file?

/etcCorrect · your answerCorrect: /etc holds configuration local to this machine.
/usr/bin/usr/bin holds executables, the thing the task avoids touching.
/var/var holds changing data such as logs and spools, not settings.
/proc/proc exposes kernel and process state, and is not editable configuration.

Correct.

Checked against man7.org, August 2026

Concept

The hierarchy separates a program's executable code from the settings that make one machine differ from another, so configuration lives in its own tree.

Why A

Machine-local configuration files live under /etc, so the daemon's settings file is edited there while its binaries stay untouched elsewhere.

Source

/etc Contains configuration files which are local to the machine.

No account needed. The explanation opens when you answer.

Sample question 1 of 3

1-1System Management

A rebuilt system fails to start because its kernel image was copied to a nonstandard path. Which locations does the hierarchy permit for the kernel?

Sample question 2 of 3

1-1System Management

A job writes scratch files that keep vanishing after reboots, with no errors logged. The files sit in a directory whose contract allows exactly that. Which one?

Sample question 3 of 3

1-1System Management

Disk monitoring shows one top-level directory growing daily on a mail server, driven by queues and logs. Which directory is behaving as designed?
