Master the CompTIA Linux+ exam with our comprehensive Q&A collection. Review questions by topic, understand explanations, and build confidence for exam day.
Strategies to help you tackle CompTIA Linux+ exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for CompTIA Linux+
pstree is correct because it displays running processes in a tree format showing parent-child relationships clearly. ps aux shows processes in a flat list format without hierarchy. top -h displays the help menu for the top command. systemctl list-processes is not a valid systemctl command.
systemctl enable is correct because it creates the necessary symbolic links to configure a service to start automatically at boot time. systemctl start only starts the service immediately but doesn't configure it for automatic startup. systemctl reload reloads the configuration of a running service. systemctl status only displays the current status of the service.
grep -r 'database_password' /var/www is correct because the -r flag enables recursive searching through all subdirectories for the specified text string within file contents. find -name searches for filenames, not file contents. locate searches a database of filenames, not content. cat with wildcard won't recurse into subdirectories and will fail on directories.
firewall-cmd --permanent --add-service=https is correct because it adds the HTTPS service rule permanently to the firewall configuration. Without --permanent, the rule would only apply to the running configuration and be lost after reload or reboot. While iptables and ufw can accomplish similar goals, the question specifically asks for firewalld. The command should be followed by firewall-cmd --reload to activate the permanent rule.
The system is overloaded is correct because load average represents the number of processes waiting for CPU time. A load average significantly higher than the number of CPU cores (15.3 vs 4 cores) indicates the system is heavily overloaded. Load averages are not percentages but represent the average number of processes in a runnable or uninterruptible state. The three numbers represent 1, 5, and 15-minute averages, showing sustained high load.

Common questions about the exam format and questions
The CompTIA Linux+ exam typically contains 50-65 questions. The exact number may vary, and not all questions may be scored as some are used for statistical purposes.
The exam includes multiple choice (single answer), multiple response (multiple correct answers), and scenario-based questions. Some questions may include diagrams or code snippets that you need to analyze.
Questions are weighted based on the exam domain weights. Topics with higher percentages have more questions. Focus your study time proportionally on domains with higher weights.
Yes, most certification exams allow you to flag questions for review and return to them before submitting. Use this feature strategically for difficult questions.
Practice questions are designed to match the style, difficulty, and topic coverage of the real exam. While exact questions won't appear, the concepts and question formats will be similar.
