Question 1

In CI, what does a 'broken build' notification ideally trigger first?

Accepted Answer

Developer who broke the build fixes it before committing more code

Answer

The developer responsible for the failing commit should stop other work and fix the build immediately to unblock the team.

Question 2

Which metric best indicates the health of a CI pipeline over time?

Accepted Answer

Mean time to restore a broken build

Answer

Mean time to restore (MTTR) reflects how quickly the team responds to and resolves build failures.

Question 3

What is 'test flakiness' in the context of CI?

Accepted Answer

Tests that randomly pass or fail without code changes

Answer

Flaky tests produce inconsistent results, eroding trust in the CI pipeline and hiding real failures.

Question 4

A team notices their CI build takes 45 minutes. What is the recommended Agile approach?

Accepted Answer

Parallelize tests and optimize the pipeline to keep builds under 10 minutes

Answer

Fast feedback is essential to CI; pipelines exceeding ~10 minutes discourage frequent commits and slow the feedback loop.

Question 5

What is the purpose of a 'staging' environment in a CI/CD pipeline?

Accepted Answer

To provide a production-like environment for final validation before release

Answer

Staging mirrors production to catch integration, configuration, and environment-specific issues before deployment.
