Question 1
A Linux administrator is making changes to local files that are part of a Git repository. The administrator needs to retrieve changes from the remote Git repository. Which of the following commands should the administrator use to save the local modifications for later review?
  1. git stash
  2. git pull
  3. git merge
  4. git fetch
Correct answer: A
Explanation:
The git stash command temporarily saves local modifications without committing them, allowing the administrator to safely run git pull or git fetch later and then reapply the saved changes.

Question 2
Which of the following best describes a use case for playbooks in a Linux system?
  1. To provide a set of tasks and configurations to deploy an application.
  2. To provide the instructions for implementing version control on a repository.
  3. To provide the security information required for a container.
  4. To provide the storage volume information required for a pod.
Correct answer: A
Explanation:
In Ansible, a playbook is a YAML file that defines tasks, configurations, and automation workflows. It is commonly used to deploy applications, configure systems, and manage infrastructure on Linux systems.

Question 3
Which of the following utilities supports the automation of security compliance and vulnerability management?
  1. SELinux
  2. Nmap
  3. AIDE
  4. OpenSCAP
Correct answer: D
Explanation:
OpenSCAP is a framework that automates security compliance checking and vulnerability management by using standardized security content (SCAP). It helps administrators enforce policies and detect vulnerabilities.

Question 4
To perform a live migration, which of the following must match on both host servers? (Choose two.)
  1. USB ports.
  2. Network speed.
  3. Available swap.
  4. CPU architecture.
  5. Available memory.
  6. Disk storage path.
Correct answer: DF
Explanation:
CPU architecture must match because live migration requires CPU compatibility to continue running the virtual machine without errors.Disk storage path must match so the migrated VM can access its virtual disks seamlessly on the destination host.

Question 5
A Linux systems administrator needs to extract the contents of a file named /home/dev/web.bkp to the /var/www/html/ directory. Which of the following commands should the administrator use?
  1. cd /var/www/html/ && gzip -c /home/dev/web.bkp | tar xf –
  2. pushd /var/www/html/ $$ cpio -idv < /home/dev/web.bkp && popd
  3. tar -c -f /home/dev/web.bkp /var/www/html/
  4. unzip -c /home/dev/web.bkp /var/www/html/
Correct answer: B
Explanation:
The .bkp file here is a cpio archive, not a tar or zip. The correct way to extract it is by changing into the target directory (/var/www/html/) and using cpio -idv < /home/dev/web.bkp. The pushd and popd commands ensure the administrator returns to the original directory afterward.

Question 6
A Linux administrator needs to create and then connect to the app-01-image container. Which of the following commands accomplishes this task?
  1. docker run -it app-01-image
  2. docker start -td app-01-image
  3. docker build -ic app-01-image
  4. docker exec -dc app-01-image
Correct answer: A
Explanation:
The docker run -it command both creates a new container from the specified image and attaches to it interactively, which is exactly what the administrator needs.

Question 7
Which of the following filesystems contains non-persistent or volatile data?
  1. /boot
  2. /usr
  3. /proc
  4. /var
Correct answer: C
Explanation:
The /proc filesystem is a virtual filesystem that provides process and kernel information. It is non-persistent and volatile, meaning its contents exist only in memory and are regenerated at each system boot.

Question 8
In the echo “profile-$num-$name” line of a shell script, the variable $num seems to not be expanding during execution. Which of the following notations ensures the value is expanded?
  1. echo “profile-$(num)-$name”
  2. echo ‘profile-$num-$name’
  3. echo “profile-‘Snum‘-$name”
  4. echo “profile-${num}-$name”
Correct answer: D
Explanation:
Using ${num} ensures correct variable expansion, especially when variables are adjacent to other characters or hyphens. This prevents ambiguity and guarantees $num is properly expanded within the string.

Question 9
Which of the following describes the method of consolidating system events to a single location?
  1. Log aggregation.
  2. Health checks.
  3. Webhooks.
  4. Threshold monitoring.
Correct answer: A
Explanation:
Log aggregation is the process of collecting and consolidating logs from multiple sources into a single location, making it easier to analyze and manage system events.

Question 10
A Linux administrator wants to add a user to the Docker group without changing their primary group. Which of the following commands should the administrator use to complete this task?
  1. sudo groupmod docker user
  2. sudo usermod -g docker user
  3. sudo usermod -aG docker user
  4. sudo groupmod -G docker user
Correct answer: C
Explanation:
The usermod -aG command appends (-a) the user to a supplementary group (-G) without changing their primary group. This is the correct way to add a user to the docker group.
The usermod -aG command appends (-a) the user to a supplementary group (-G) without changing their primary group. This is the correct way to add a user to the docker group.
Question 11
A DevOps engineer made some changes to files on a local repository. The engineer realizes that the changes broke the application and the changes need to be reverted back. Which of the following commands is the best way to accomplish this task?
  1. git pull
  2. git reset
  3. git rebase
  4. git stash
Correct answer: B
Explanation:
The git reset command reverts changes in the local repository to a previous commit, effectively discarding the problematic modifications and restoring the application to a working state.
