Quick Answer
The answer is the iterative life cycle. This is the correct choice because an agile approach with iterative cycles explicitly defines a project life cycle where scope is refined through repeated cycles of planning, execution, and evaluation, allowing the team to adapt to feedback and evolving requirements. On the CompTIA Project+ PK0-005 exam, this question tests your ability to distinguish between predictive, iterative, incremental, and adaptive life cycles; a common trap is confusing iterative with incremental, but remember that iterative focuses on progressively improving a product through repeated loops, while incremental adds new features piece by piece. A helpful memory tip is to think of the word “iterate” as meaning “to repeat”—just like an agile sprint cycle, you keep looping back to refine the work until it meets the customer’s needs.
This PK0-005 practice question tests your understanding of project life cycle phases. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A project manager is leading a software development project. The team is using an agile approach with iterative cycles. Which project life cycle model best describes this approach?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Waterfall life cycle
Why wrong: Waterfall is a sequential, predictive model.
Predictive life cycle
Why wrong: Predictive life cycles are plan-driven, with fixed scope upfront.
Iterative life cycle
Iterative cycles allow for refinement through repeated phases.
Spiral life cycle
Why wrong: Spiral is a risk-driven model not specifically describing agile iterative cycles.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Iterative life cycle
An agile approach with iterative cycles is characteristic of an iterative or adaptive life cycle, where scope is refined through repeated cycles.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Waterfall life cycle
Why it's wrong here
Waterfall is a sequential, predictive model.
Predictive life cycle
Why it's wrong here
Predictive life cycles are plan-driven, with fixed scope upfront.
Iterative life cycle
Why this is correct
Iterative cycles allow for refinement through repeated phases.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept

Spiral life cycle
Why it's wrong here
Spiral is a risk-driven model not specifically describing agile iterative cycles.
Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
