FC0-U71 Practice Question: A project has frequent requirement changes and…
A project has frequent requirement changes and the team needs to deliver working software in short cycles. Which software development methodology is most appropriate?
⚠ Common exam trap
CompTIA often tests the distinction between Agile (a development methodology) and DevOps (a deployment/operations practice), leading candidates to confuse the two when the question focuses on requirement changes and short delivery cycles.
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
✓
Agile
Agile methodology is the most appropriate because it explicitly supports iterative development, frequent requirement changes, and short delivery cycles through practices like sprints and continuous feedback. Unlike rigid sequential models, Agile embraces change even late in development, making it ideal for projects where requirements evolve rapidly.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Waterfall
Why it's wrong here
Waterfall completes sequential phases with requirements frozen before design, so late changes force costly rework and no working software appears until the end. It suits stable, well-understood requirements with fixed scope, not this scenario's frequent changes and short delivery cycles.
- ✓
Agile
Why this is correct
Agile delivers working software in short, fixed-length iterations, so changing requirements are absorbed between sprints rather than frozen at the outset. This directly satisfies the stem's demand for frequent requirement changes plus rapid delivery cycles, unlike sequential waterfall, which locks scope before development begins.
- ✗
DevOps
Why it's wrong here
DevOps is a culture and toolchain practice automating build, test and deployment between development and operations; it does not itself define how requirements are gathered or iterations structured. Agile methods such as Scrum provide the short-cycle delivery this project needs.
- ✗
Spiral
Why it's wrong here
Spiral iterates through risk analysis and prototyping, suiting large, high-risk projects with evolving architecture, but its long cycles and heavy documentation do not deliver working software in short repeated increments. Scrum or XP would fit the frequent-change, short-cycle requirement.
