PK0-005 Practice Question: Which TWO of the following are characteristics of…
Which TWO of the following are characteristics of the waterfall project management methodology?
⚠ Common exam trap
The PK0-005 exam often tests the misconception that waterfall allows for iterative feedback or incremental delivery, when in reality it is strictly sequential and phase-gated, and candidates may confuse 'phase gates' with 'sprint reviews' from agile.
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
✓
Distinct phase gates
The waterfall methodology enforces distinct phase gates (e.g., requirements, design, implementation, testing, deployment) where each phase must be fully completed and formally reviewed before the next phase begins. This gate-based approach ensures that deliverables are approved at each stage, preventing overlapping or concurrent work.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Continuous delivery of small increments
Why it's wrong here
This describes Agile, not Waterfall.
- ✗
Iterative cycles with feedback
Why it's wrong here
Iterative cycles are Agile.
- ✓
Distinct phase gates
Why this is correct
Waterfall has review gates between phases.
- ✓
Linear and sequential phases
Why this is correct
Waterfall progresses through phases in order.
- ✗
Flexible scope changes
Why it's wrong here
