A CI/CD pipeline for a Python application is failing intermittently during the test stage. The error message indicates that a test database is not reachable. The tests run in a Docker container, and the database is also a container. What is the most likely cause?

The test code has a syntax error.

The build artifacts are corrupted.

The pipeline is using the wrong branch.

The test container is starting before the database container is ready.

A company's CI/CD pipeline is experiencing long queue times during peak hours. The pipeline uses a fixed number of build agents. The team wants to reduce wait times without over-provisioning resources during off-peak hours. Which solution is most cost-effective?

Move to a cloud-based CI service with a fixed number of runners.

Use auto-scaling build agents that scale up during peak hours and scale down during off-peak hours.

Increase the number of build agents permanently.

Limit the number of concurrent builds.

What is the main benefit of automating the build process in a CI/CD pipeline?

It automatically fixes code errors

It ensures consistent compilation and packaging across environments

It removes the need for automated testing

It eliminates the need for version control
