CompTIA Linux+ Practice Questions

Master the Automation, Orchestration, and Scripting Domain

Test your knowledge in the Automation, Orchestration, and Scripting 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

Which of the following is a common mistake when writing a shell script that leads to security vulnerabilities?

A) Using 'echo' for output

B) Hardcoding sensitive information

C) Using 'read' for input

D) Using 'if' conditions

Show Answer & Explanation

Correct Answer: B

Explanation: Hardcoding sensitive information such as passwords in scripts is a common security vulnerability. 'echo' and 'read' are standard input/output operations, and 'if' conditions are control structures, none of which inherently pose security risks.

Question 2

In a containerized environment, which tool would you use to define and run multi-container Docker applications?

A) Docker CLI

B) Kubernetes

C) Docker Compose

D) OpenStack

Show Answer & Explanation

Correct Answer: C

Explanation: Docker Compose is a tool for defining and running multi-container Docker applications. It uses a YAML file to configure the application's services. Docker CLI is for managing individual Docker containers, Kubernetes is for orchestrating containers across clusters, and OpenStack is a cloud computing platform.

Question 3

In an orchestration context, what is the primary role of a tool like Terraform?

A) To monitor system performance

B) To automate software installation

C) To provision and manage infrastructure

D) To configure network settings

Show Answer & Explanation

Correct Answer: C

Explanation: Terraform is an open-source tool that enables users to provision and manage infrastructure as code. It is not used for monitoring, software installation, or configuring network settings directly.

Question 4

What is the primary function of 'Jenkins' in a DevOps pipeline?

A) Source code management

B) Continuous integration and delivery

C) Infrastructure monitoring

D) Container orchestration

Show Answer & Explanation

Correct Answer: B

Explanation: Jenkins is primarily used for continuous integration and delivery (CI/CD) in a DevOps pipeline. It automates the process of building, testing, and deploying code. Source code management is typically handled by tools like Git, infrastructure monitoring by tools like Nagios, and container orchestration by Kubernetes.

Question 5

A script needs to execute only if a specific service is running on a CentOS server. Which command would you use to check the status of the service?

A) service status

B) systemctl is-active

C) chkconfig --list

D) systemctl enable

Show Answer & Explanation

Correct Answer: B

Explanation: The 'systemctl is-active' command checks if a service is active (running) on systems using systemd, such as CentOS. 'service status' is not a valid command, 'chkconfig --list' is used for listing services and their runlevels, and 'systemctl enable' is used to enable a service to start at boot.

Question 6

You have a script that is failing intermittently when run on a CentOS server. The script is supposed to create a backup of a directory and store it in a remote location. What is the first step you should take to troubleshoot this issue?

A) Check the script for syntax errors.

B) Verify network connectivity to the remote location.

C) Review the script's logs for error messages.

D) Increase the script's execution timeout.

Show Answer & Explanation

Correct Answer: C

Explanation: Reviewing the script's logs for error messages is the first step in troubleshooting, as it can provide specific information about what went wrong during execution. Option A, checking for syntax errors, is less likely to be the cause of intermittent failures. Option B, verifying network connectivity, is important but should follow checking the logs. Option D, increasing the script's execution timeout, is not a first-step action and should be considered only if timeouts are identified as the issue.

Question 7

You need to automate the deployment of a web server on multiple servers. Which tool would be best suited for this task?

A) Bash script

B) Ansible

C) Grep

D) sed

Show Answer & Explanation

Correct Answer: B

Explanation: Ansible is an automation tool that is used for configuration management, application deployment, and task automation on multiple servers. A Bash script can automate tasks but lacks the scalability and manageability of Ansible. 'Grep' and 'sed' are text processing tools.

Question 8

A developer needs to ensure that a script only runs if a specific file is present. Which bash construct should they use?

A) if [ -f /path/to/file ]; then

B) if [ -d /path/to/file ]; then

C) if [ -e /path/to/file ]; then

D) if [ -s /path/to/file ]; then

Show Answer & Explanation

Correct Answer: A

Explanation: The '-f' flag in bash checks if a file exists and is a regular file. '-d' checks for directories, '-e' checks for existence of any file type, and '-s' checks if the file exists and is not empty.

Question 9

In a hybrid cloud environment, which tool would you use to automate the provisioning of infrastructure across multiple cloud providers?

A) Terraform

B) Kubernetes

C) Jenkins

D) Nagios

Show Answer & Explanation

Correct Answer: A

Explanation: Terraform is an open-source infrastructure as code software tool that provides a consistent CLI workflow to manage hundreds of cloud services. It is particularly useful for managing infrastructure across multiple cloud providers. Kubernetes is for container orchestration, Jenkins is for continuous integration/continuous deployment (CI/CD), and Nagios is for monitoring.

Question 10

In a hybrid cloud environment, which tool is commonly used for orchestrating container deployments?

A) Docker Compose

B) Kubernetes

C) Ansible

D) Vagrant

Show Answer & Explanation

Correct Answer: B

Explanation: Kubernetes is widely used for orchestrating container deployments in cloud and hybrid environments due to its robust features for managing containerized applications. Docker Compose is for defining and running multi-container Docker applications, Ansible is for configuration management, and Vagrant is for managing virtual machine environments.
