However, the deploy stage should only run if the build and test stages are successful. How can you ensure that the deploy stage only runs after the successful completion of the build and test stages?

Options :

A : Use dependencies keyword to specify that the deploy stage depends on the build and test stages.

B : Use allow_failure: true in the build and test stages.

C : Place the deploy stage after the build and test stages in the pipeline configuration.

D : Use needs keyword to ensure the deploy stage waits for build and test stages to complete.

Answer: C

Question 5

In a GitLab CI/CD pipeline, how can you ensure that a job named deploy will only run after the successful completion of the build and test jobs?

Options :

A : Use the dependencies keyword to specify build and test in the deploy job.

B : Use the before_script keyword in the deploy job to run build and test scripts.

C : Use the stages keyword to define build, test, and deploy stages.
