design, implementation, and testing.
3. What is a key characteristic of Agile methodology?
A) Fixed requirements
B) Iterative development
C) Minimal customer involvement
D) Single delivery phase

A) Automate testing
B) Manage source code changes
C) Design user interfaces
D) Deploy software
Correct Answer: B) Manage source code changes
Rationale: Version control tracks code changes, enabling collaboration and rollback.
6. Which testing level focuses on individual components or modules?
A) System testing
B) Integration testing
C) Unit testing
D) Acceptance testing
Correct Answer: C) Unit testing
Rationale: Unit testing verifies the functionality of individual code units in isolation.
