Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Code reviews
Code reviews ensure code quality and security. Static application security testing (SAST) identifies vulnerabilities in source code. Unit testing validates individual components. These are key controls in iterative development.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Formal sign-off on requirements before each iteration
Why it's wrong here
Iterative approaches welcome changing requirements; formal sign-off at each iteration is not typical.
- ✓
Code reviews
Why this is correct
Code reviews are a key control for ensuring code quality and security in each iteration.
- ✗
User acceptance testing (UAT) before each iteration
Why it's wrong here
UAT is typically performed at the end of a release or after several iterations, not after every iteration.
- ✓
Static application security testing (SAST)
Why this is correct
SAST identifies vulnerabilities in source code during development.
- ✓
Unit testing
Why this is correct
Unit testing verifies individual components and is performed during each iteration.
