20+ practice questions focused on Project Life Cycle Phases — one of the most tested topics on the CompTIA Project+ PK0-005 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Project Life Cycle Phases PracticeA project manager is reviewing lessons learned from a previous project and notices that scope creep occurred because stakeholders requested changes after the project moved into the execution phase. Which action should the project manager take in the current project to prevent this issue?
Explanation: Option D is correct because establishing a change control board (CCB) during the planning phase provides a formal, documented process for reviewing and approving or rejecting scope changes. This prevents uncontrolled scope creep by ensuring that any change request is evaluated for impact on cost, schedule, and resources before implementation, which is a key practice in the PMBOK Guide for the execution phase.
During the execution phase, a project manager discovers that the development team has been using an unauthorized software library to accelerate work. The library has a license that could create legal risks for the company. What is the best course of action?
Explanation: Option B is correct because using an unauthorized software library with a license that creates legal risks must be stopped immediately to protect the company from potential litigation. The project manager must then assess the schedule impact and develop a replacement plan, as continuing use without addressing the legal risk violates compliance and project governance standards.
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?
Explanation: 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.
A project is in the execution phase, and the project manager receives a change request to add a new feature that is not in the scope statement. The change request has been approved by the change control board. What must the project manager do next?
Explanation: Once the change control board (CCB) approves a change request, the project manager must formally integrate the approved change into the project by updating the project management plan and the associated baselines (scope, schedule, cost). This ensures that all future project work, performance measurement, and reporting are aligned with the new approved scope, maintaining the integrity of the project's control processes as defined in the PMBOK Guide.
A project manager is creating a work breakdown structure (WBS) during the planning phase. The WBS should decompose the project deliverables into smaller, manageable components. What is the lowest level of a WBS called?
Explanation: The lowest level of a work breakdown structure (WBS) is the work package, which represents the smallest unit of work that can be reliably estimated, assigned, and managed. Decomposing deliverables into work packages enables precise cost, resource, and schedule planning during the project planning phase.

Practice all Project Life Cycle Phases questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Project Life Cycle Phases. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Project Life Cycle Phases questions on the PK0-005 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Project Life Cycle Phases is tested as part of the CompTIA Project+ PK0-005 blueprint. Practicing with targeted Project Life Cycle Phases questions ensures you can handle any format or difficulty that appears.
