CompTIA Linux+ Practice Questions
Master the System Management Domain
Test your knowledge in the System Management domain with these 10 practice questions. Each question is designed to help you prepare for the CompTIA Linux+ certification exam with detailed explanations to reinforce your learning.
Question 1
In a hybrid cloud environment, which tool would you primarily use to automate the deployment of containers?
Show Answer & Explanation
Correct Answer: C
Explanation: Kubernetes is a platform designed for automating the deployment, scaling, and operation of application containers across clusters of hosts. Ansible and Terraform are used for automation and infrastructure as code but are not specifically for container orchestration. Docker is used for building and running containers but not for orchestrating them across a cluster.
Question 2
Which command can be used to monitor real-time disk I/O on a Linux system?
Show Answer & Explanation
Correct Answer: D
Explanation: 'iotop' is a command that displays a table of current I/O usage by processes or threads on Linux systems. 'iostat' provides CPU and I/O statistics but not in real-time. 'vmstat' reports virtual memory statistics, and 'sar' collects, reports, or saves system activity information.
Question 3
In a containerized environment, which command would you use to view logs of a running Docker container?
Show Answer & Explanation
Correct Answer: B
Explanation: The 'docker logs' command is used to fetch the logs of a container. 'docker ps' lists running containers, 'docker exec' runs a command in a running container, and 'docker inspect' returns low-level information on Docker objects.
Question 4
A user needs to be added to multiple groups on a SUSE Linux server. Which command should be used?
Show Answer & Explanation
Correct Answer: A
Explanation: The 'usermod -a -G' command is used to add an existing user to one or more groups without removing them from other groups. 'groupadd' is used to create new groups, 'adduser' is used to create new users, and 'gpasswd' administers the /etc/group file.
Question 5
You are tasked with configuring a new service to start automatically on boot in a RHEL-based system. Which command should you use?
Show Answer & Explanation
Correct Answer: A
Explanation: The 'systemctl enable' command is used to enable a service to start automatically at boot time in systems using systemd, such as RHEL. 'systemctl start' starts the service immediately but does not enable it to start on boot. 'chkconfig on' is used in older SysVinit systems. 'service start' starts a service but does not configure it to start on boot.
Question 6
Which command would you use to list all currently loaded kernel modules in a Linux system?
Show Answer & Explanation
Correct Answer: A
Explanation: The 'lsmod' command is used to list all currently loaded kernel modules. 'modprobe' is used to add or remove modules from the kernel, 'insmod' is used to insert a module into the Linux kernel, and 'rmmod' is used to remove a module from the Linux kernel.
Question 7
A Linux server is experiencing high CPU load due to a specific process. Which command can you use to change the priority of this process to reduce its impact?
Show Answer & Explanation
Correct Answer: B
Explanation: The 'renice' command is used to change the priority of an already running process. 'kill' is used to terminate processes, 'ps' is used to display information about active processes, and 'top' is used to monitor processes but does not change their priority.
Question 8
A user reports that they cannot access a shared directory on a Linux server. Which command would you use first to check the permissions of the directory?
Show Answer & Explanation
Correct Answer: A
Explanation: The 'ls -l' command lists directory contents in long format, showing file permissions, ownership, and other details. 'chmod' changes file permissions, 'chown' changes file ownership, and 'umask' sets default permissions for new files and directories.
Question 9
You need to troubleshoot a network issue on an Ubuntu server. Which command will display the current IP routing table?
Show Answer & Explanation
Correct Answer: C
Explanation: The 'ip route show' command displays the current IP routing table on Linux systems. 'ifconfig' is used to configure network interfaces, 'netstat -r' can also show the routing table but is less preferred in modern systems, and 'route print' is a command used in Windows.
