Question 4

A DevOps engineer wants to optimize a GitLab CI/CD pipeline using Directed Acyclic Graph (DAG) execution to allow jobs in different stages to run in parallel when there are no explicit dependencies. The engineer writes the following .gitlab-ci.yml configuration:

Which statement best describes how this pipeline will execute?

Options :

A : The pipeline will allow jobs to run in parallel within the same stage but still enforce stage ordering.

B : The pipeline will execute all jobs simultaneously because there are no explicit dependencies.

C : The pipeline will use a DAG by default and optimize execution based on detected dependencies.

D : The pipeline will execute all jobs in a strictly sequential manner based on the stages definition.

Answer: A
