Linux+ Certification Sample Questions and Answers

Here are realistic examples of what you might encounter on the actual exam, covering key topics and difficulty levels that reflect the current XK0-005 objectives.

Question 1:

A Linux administrator wants to schedule a script to run every day at 2 AM. Which of the following should the administrator use?

1. cron
   B. systemctl
   C. top
   D. ps

The Correct Answer is: A. cron

The cron daemon is used in Linux to schedule tasks to run at specific times or intervals. By editing a crontab file, an administrator can configure a script to execute every day at 2 AM. This makes cron the most effective and reliable scheduling tool for repetitive automation tasks compared to other system monitoring or process management utilities.

Why Other Options are Incorrect:

• B. systemctl: Used to control and manage systemd services, such as starting or stopping daemons. It is not designed for scheduling repetitive jobs.
• C. top: Displays real-time system processes, CPU, and memory usage. It cannot schedule tasks to run automatically.
• D. ps: Shows currently running processes and their status. It provides process information but does not execute or schedule future tasks.

Question 2:

Which command is best suited for finding specific text inside log files on a Linux system?

1. grep
   B. chmod
   C. ls
   D. df

The Correct Answer is: A. grep

The grep command searches through files for specific patterns or strings of text. When troubleshooting or analyzing logs, administrators commonly use grep to locate error messages, keywords, or event information within large log files. This makes it the most efficient and accurate command for quickly isolating relevant text in Linux environments, unlike commands that manage files or disk usage.

Why Other Options are Incorrect:

• B. chmod: Changes file permissions but cannot search for text within files.
• C. ls: Lists files and directories in a path but does not search for file contents.
• D. df: Displays disk usage and available space, not text patterns inside files.

Question 3:

A Linux administrator notices that a filesystem has reached 95% usage. Which of the following commands should be used first to identify which directories are consuming the most space?

1. du
   B. touch
   C. uname
   D. kill

The Correct Answer is: A. du

The du (disk usage) command summarizes the amount of disk space used by files and directories. By combining it with options such as du -sh *, administrators can identify which directories consume the most space. This makes du the most appropriate tool for investigating storage problems compared to commands used for process termination, file creation, or system information.

Why Other Options are Incorrect:

• B. touch: Creates empty files or updates timestamps but does not show disk usage.
• C. uname: Displays system information such as kernel version but is unrelated to storage usage.
• D. kill: Sends signals to terminate processes and has no role in disk space analysis.
