PK0-005 Practice Question: A project manager is planning a software…
A project manager is planning a software development project and needs to determine the sequence of activities. The team will first gather requirements, then design the architecture, then develop the code, then test, and finally deploy. Which project life cycle model is being used?
⚠ Common exam trap
Watch out — candidates often confuse the sequential phase names with Agile or Iterative terminology, forgetting that Waterfall is defined by its strict linearity and lack of overlapping phases or feedback cycles.

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
✓
Waterfall
The Waterfall model (Option C) is correct because it follows a strictly sequential, phase-by-phase progression: requirements, design, development, testing, and deployment, with no overlap or iteration. This linear approach is characteristic of the Waterfall life cycle, where each phase must be completed before the next begins, as described in the PMBOK Guide for predictive life cycles.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Iterative
Why it's wrong here
Iterative models repeat phases to refine deliverables, not a single pass.
- ✗
Agile
Why it's wrong here
Agile uses short iterations and adapts to change, not a rigid sequence.
- ✓
Waterfall
Why this is correct
Waterfall is linear and sequential, with phases completed one after another.
- ✗
Spiral
Why it's wrong here
Spiral focuses on risk assessment and iterative prototyping.
