PK0-005 Project Life Cycle Phases — Timed 10 Questions

Question 1

A 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?

Accepted Answer

Establish a change control board during the planning phase to review and approve any change requests.. 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.

Answer

Close the project early if any scope changes are requested.

Answer

Involve all stakeholders in the project planning phase to ensure requirements are fully captured.

Answer

Include a detailed list of all deliverables in the project charter to avoid ambiguity.

Question 2

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?

Accepted Answer

Immediately stop using the library, assess the impact on the schedule, and develop a plan to replace it.. 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.

Answer

Document the issue in the lessons learned and continue with the library to avoid delay.

Answer

Continue using the library but add a note in the risk register about potential licensing issues.

Answer

Escalate the issue to the project sponsor and request a decision on whether to continue using the library.

Question 3

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?

Accepted Answer

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

Iterative

Answer

Agile

Answer

Spiral

Question 4

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?

Accepted Answer

Update the project management plan and baseline to reflect the approved change.. 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.

Answer

Conduct a meeting with stakeholders to discuss the impact of the change.

Answer

Defer the change to the next project phase to minimize disruption.

Answer

Inform the development team to continue with the original scope and ignore the change.

Question 5

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?

Accepted Answer

Work package. 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.

Answer

Planning package

Answer

Control account

Answer

Activity

Question 6

During the closing phase of a project, which TWO activities should be performed?

Accepted Answer

Archive project documents and lessons learned.. Archiving project documents and lessons learned (Option A) is a key closing-phase activity because it preserves project knowledge for future reference and organizational process assets. Formal acceptance of deliverables from stakeholders (Option C) ensures that all project outputs have been reviewed and approved, formally closing the project scope. Both activities are explicitly part of the closing process group in the CompTIA PK0-005 exam objectives.

Answer

Update the risk register with new risks identified during execution.

Answer

Create the project charter.

Answer

Develop a work breakdown structure.

Question 7

A project manager is using a predictive (waterfall) life cycle for a construction project. Which THREE documents are typically created during the planning phase?

Accepted Answer

Risk register. In a predictive (waterfall) life cycle, the planning phase produces detailed documents that define how the project will be executed, monitored, and controlled. The risk register (B) is created to identify, assess, and plan responses to potential risks. The schedule baseline (C) is the approved version of the project schedule that becomes the reference for performance measurement. The scope statement (E) formally documents the project scope, including deliverables, assumptions, and constraints. These three artifacts are all outputs of the planning process group in a waterfall methodology.

Answer

Project charter

Answer

Lessons learned register

Question 8

Refer to the exhibit. A server administrator is troubleshooting a failed backup job. Based on the logs and configuration files, what is the most likely cause of the error?

Accepted Answer

The backup volume's filesystem label or UUID does not match the expected value in the backup software configuration.. The backup software configuration specifies a filesystem label or UUID for the backup volume, but the actual volume has a different label or UUID. This mismatch causes the backup job to fail because the software cannot locate the intended target volume. The logs would show errors related to mounting or accessing the volume by its expected identifier.

Answer

The backup volume has a corrupted filesystem.

Answer

The backup volume is out of space.

Answer

The backup script is not scheduled to run at the correct time.

Question 9

Refer to the exhibit. A developer deployed a new version of an application to production. After restarting the service, the application fails to connect to the database. What is the most likely cause?

Accepted Answer

The database user 'app_user' does not have permission to access the 'SalesDB' database.. The exhibit shows that the connection string in the application configuration explicitly references the 'SalesDB' database and uses the 'app_user' account. The error message indicates a login failure for user 'app_user', which in SQL Server typically means the login succeeded at the server level but the user lacks a mapped database user or the CONNECT permission on the specified database. Since the database name and server are correctly specified, the most likely cause is that 'app_user' does not have permission to access 'SalesDB'.

Answer

The database server name in the configuration is incorrect.

Answer

The application is not configured to use the correct environment.

Answer

The password in the connection string is incorrect.

Question 10

During the execution phase of a software development project, the team discovers that the database schema needs to be altered to accommodate a new regulatory requirement. The project manager is reviewing the change request. What is the MOST important factor to consider before approving the change?

Accepted Answer

The change's impact on the project's schedule, cost, and scope must be analyzed.. Option C is correct because any change to a database schema during the execution phase of a software development project carries significant risk to schedule, cost, and scope. The project manager must perform a formal impact analysis to understand how the schema alteration affects existing data integrity, application code dependencies, testing cycles, and deployment timelines before approving the change. This aligns with the integrated change control process defined in the PMBOK Guide and is critical for maintaining project baselines.

Answer

The project manager must approve the change to avoid delaying the project.

Answer

The team should implement the change immediately to meet the regulatory deadline.

Answer

The change should be approved if it is within the current phase's budget.
