  A. Builds should be self-testing. That allows us maximum flexibility in spotting breaking changes and prevents a lot of staff time spent trying to both integrate a change and determine why it broke the build.

  B. We should really use a single source repository. That makes it easier for us to manage what gets into the build pipeline.

  C. Build everything manually, because that prevents errors.

  D. Every commit should be built. That ensures we don't wind up with a lot of stray code and that any future change will be testable.

  Correct Answer: C

  CI relies heavily on automation, especially build automation, to enable the sped-up pace of code commits. If things are built manually, the pipeline is slowed down, and the ability to maintain a fast change pace is inhibited.
