Question 1

You are working on a project in GitLab that involves multiple environments (development, staging, production). Each environment requires different configurations and credentials. Recently, you’ve observed that the deployment to the production environment sometimes fails due to incorrect configurations being used. Which approach is best to ensure that each environment gets the correct configurations and credentials during deployment?

Options :

A : Manually change the configurations and credentials in the code before each deployment.

B : Store all configurations and credentials directly in the .gitlab-ci.yml file.

C : Use GitLab environment variables to manage different configurations and credentials.

D : Deploy only to the development environment and manually move the code to staging and production.

Answer: C

Question 2

You are managing a GitLab instance with several projects under a single group. To optimize resource usage and manage CI/CD pipelines more efficiently, you decide to use Group Runners instead of project-specific runners. Which of the following statements correctly describes the benefit of using Group Runners in this context?

Options :

A : Group Runners provide a unique configuration per project, leading to more customizable CI/CD pipelines.

B : Group Runners can only be used by projects that have a premium subscription.

C : Group Runners can be shared among all projects within the group, reducing the need to manage multiple runners for each project.

D : Group Runners are automatically assigned to each project, and cannot be unassigned.

Answer: C

Question 3

A DevOps engineer is configuring a GitLab CI/CD pipeline with multiple jobs. They need to ensure that certain jobs execute before others while optimizing the pipeline's efficiency. Which of the following best describes how GitLab determines the order of job execution in a pipeline?

Options :

A : Jobs execute sequentially from top to bottom as they appear in .gitlab-ci.yml.

B : Jobs are executed in parallel by default, unless defined in separate stages.

C : The needs keyword forces all jobs to run in strict sequential order, one after another.

D : Jobs in different stages execute randomly, without any predefined sequence.

Answer: B

Question 4

You are managing a CI/CD pipeline in GitLab for a large application with multiple services. You notice that the pipeline is taking too long to complete due to numerous sequential jobs. How can you optimize the pipeline to reduce the total execution time?

Options :

A : Use pipeline caching.

B : Disable artifacts.

C : Increase the number of sequential jobs.

D : Implement parallel jobs.

Answer: D

Question 5

You want to integrate Container Scanning into your GitLab CI/CD pipeline to automatically detect vulnerabilities in your Docker images. What steps should you take to properly configure Container Scanning?

Options :

A : Add a container_scanning job in the .gitlab-ci.yml file and include security/container-scanning template.

B : Write a custom script to scan Docker images for vulnerabilities and integrate it into the build stage of the pipeline.

C : Install a third-party container scanning tool on your CI runners and configure it to run during the pipeline.

D : Use the before_script section to run container scans before any other job in the pipeline.
