CompTIA Linux+ Sample Questions

Here are three realistic practice questions to demonstrate the exam format:

Question 1:

Which command is used to display the current disk usage of files and directories in Linux?
A. df
B. du
C. lsblk
D. mount

Correct Answer: B. du

The du command reports the amount of disk space used by files and directories. It is commonly used with options like -h for human-readable format and -s for summaries, providing detailed insights into storage consumption.

Why Other Options are Incorrect:

• A. df
  Incorrect because df displays filesystem-level disk space usage, not directory-level or file-level details. It shows available and used space across mounted filesystems, not specific directory sizes.
• C. lsblk
  Incorrect because lsblk lists block devices and their mount points. It provides hardware-level information about disks and partitions, not actual disk usage statistics for files and directories.
• D. mount
  Incorrect because mount is used to attach filesystems to the Linux directory tree. It does not provide information about storage consumption or directory-specific disk usage.

Question 2:

In Linux, which file contains user account information such as usernames and UIDs?
A. /etc/shadow
B. /etc/group
C. /etc/passwd
D. /etc/login.defs

Correct Answer: C. /etc/passwd

The /etc/passwd file contains essential information for user accounts, including username, UID, GID, home directory, and shell. Passwords were historically stored here but are now kept in /etc/shadow for better security.

Why Other Options are Incorrect:

• A. /etc/shadow
  Incorrect because /etc/shadow stores encrypted user passwords and related settings, not general user account details such as usernames and shells. Access is restricted for security reasons.
• B. /etc/group
  Incorrect because /etc/group contains group information such as group names and GIDs. It does not maintain user-specific information like home directories or login shells.
• D. /etc/login.defs
  Incorrect because /etc/login.defs contains configuration defaults for user account creation, not actual account information. It specifies policies like password aging but not user details.

Question 3:

Which runlevel or systemd target is used for multi-user mode with networking but without a graphical interface?
A. Runlevel 0 / poweroff.target
B. Runlevel 3 / multi-user.target
C. Runlevel 5 / graphical.target
D. Runlevel 1 / rescue.target

Correct Answer: B. Runlevel 3 / multi-user.target

Runlevel 3 (or multi-user.target in systemd) provides a non-graphical, multi-user environment with networking enabled. It is ideal for servers and headless systems that do not require a graphical desktop environment.

Why Other Options are Incorrect:

• A. Runlevel 0 / poweroff.target
  Incorrect because runlevel 0 shuts down the system and powers it off. It is not used for providing user access or running services.
• C. Runlevel 5 / graphical.target
  Incorrect because runlevel 5 enables a graphical user interface (GUI) along with networking. This is different from the text-only environment of runlevel 3.
• D. Runlevel 1 / rescue.target
  Incorrect because runlevel 1 is single-user mode, used for system maintenance or troubleshooting. It does not provide networking or multi-user functionality.
