A production fix must be reviewed and traceable. What workflow is best?

  1. A small branch and pull request with tests
  2. Edit the server directly
  3. Rewrite shared history
  4. Email a zip file
Show answer and explanation

Correct answer: A small branch and pull request with tests

A focused reviewed change preserves history and supports automated validation.

Tests pass locally but fail intermittently in CI because they share mutable data. What is the priority?

  1. Isolate test state and make setup deterministic
  2. Retry forever
  3. Ignore failures on main
  4. Run tests less often
Show answer and explanation

Correct answer: Isolate test state and make setup deterministic

Hermetic, deterministic tests remove order and shared-state dependence.

Why should the same build artifact progress through environments?

  1. It prevents environment-specific rebuild drift
  2. It makes source control unnecessary
  3. It disables rollback
  4. It guarantees zero bugs
Show answer and explanation

Correct answer: It prevents environment-specific rebuild drift

Promoting one immutable artifact ensures the tested bits are the released bits.
