1Which command changes the permissions of a file on Linux?

A.chown

B.chmod

C.chgrp

D.usermod

Explanation: chmod changes the permission bits (read, write, execute) on a file or directory. It is the canonical way to adjust file-mode permissions on Linux systems.

2Which file typically stores user account information on a Linux system?

A./etc/shadow

B./etc/passwd

C./etc/hosts

D./etc/sudoers

Explanation: /etc/passwd lists user accounts with UID, GID, home directory, and login shell. It is world-readable so services can resolve usernames.

3Which tool starts, stops, and inspects services on a modern systemd-based Linux distribution?

A.service

B.systemctl

C.init

D.rc-update

Explanation: systemctl is the primary interface to systemd units. It starts, stops, enables, disables, and reports status for services and other units.

4A system administrator wants to schedule a script to run every day at 2:30 AM. Which mechanism fits best?

A.at

B.cron

C.nohup

D.bg

Explanation: cron is designed for recurring scheduled jobs using a time-based expression. An entry like '30 2 * * *' runs daily at 2:30 AM.

5Which command shows currently running processes with a tree view of parent-child relationships?

A.ps aux

B.pstree

C.top -H

D.htop -t

Explanation: pstree prints processes in a hierarchical tree showing parent-to-child relationships, which helps visualize process ancestry quickly.

6Which directory typically contains system-wide configuration files on Linux?

A./etc

B./var

C./usr

D./opt

Explanation: Per the Filesystem Hierarchy Standard (FHS), /etc holds host-specific system configuration files for the OS and installed packages.

7Which command installs a package on a Debian or Ubuntu system?

A.dnf install nginx

B.apt install nginx

C.zypper in nginx

D.pacman -S nginx

Explanation: apt is the standard package manager front-end on Debian-based distributions such as Ubuntu. 'apt install <pkg>' resolves dependencies and installs the package.

8What does 'chmod 755 file.sh' set as permissions?

A.rwx for owner; rw for group and others

B.rwx for owner; r-x for group and others

C.rw for owner; r for group and others

D.rwx for everyone

Explanation: Octal 755 means 7 (rwx) for owner, 5 (r-x) for group, and 5 (r-x) for others. This is a common mode for executable scripts that need to be read and run by others.

9Which log file typically records system-wide authentication events on a Debian system?

A./var/log/auth.log

B./var/log/dmesg

C./var/log/boot.log

D./var/log/wtmp

Explanation: On Debian and Ubuntu, /var/log/auth.log records authentication and authorization events such as sudo use and SSH logins. On Red Hat family systems this is /var/log/secure.

10Which command shows disk space usage per filesystem?

A.du -sh

B.df -h

C.lsblk

D.blkid

Explanation: df -h reports free and used disk space per mounted filesystem in human-readable units. It is the quickest way to spot a filesystem filling up.

3Memorize the high-level difference between IaaS, PaaS, SaaS, virtualization, and containers.

4Learn the CIA triad and authentication vs authorization before diving deeper into security tools.

5Review DevOps vocabulary including CI, CD, infrastructure as code, and monitoring at a conceptual level.
