PK0-005 Constraints and Changes — Timed 30 Questions

Question 1

A project manager is creating the WBS. Which rule ensures that all deliverables and work required for the project are included in the WBS and no work is omitted?

Accepted Answer

100% rule. The 100% rule states that the WBS must capture all work defined in the project scope, ensuring nothing is left out.

Answer

Question 2

During project execution, a customer requests a new feature that was not in the original scope. The project manager receives a change request. What is the NEXT step the project manager should take?

Accepted Answer

Evaluate the impact on the triple constraint.. The first step in the integrated change control process is to evaluate the impact of the change on the triple constraint (scope, schedule, cost, quality).

Answer

Implement the change immediately to satisfy the customer.

Answer

Submit the change request to the change control board (CCB).

Answer

Update the project baselines.

Question 3

A project team is analyzing potential risks. They gather experts who provide anonymous responses to a questionnaire, and then the facilitator shares a summary for further rounds of feedback. Which risk identification technique is being used?

Accepted Answer

Delphi technique. The Delphi technique uses anonymous expert feedback through multiple rounds to reach consensus.

Answer

Brainstorming

Answer

SWOT analysis

Answer

Assumptions analysis

Question 4

A project manager is using a schedule compression technique that adds resources to critical path activities to shorten the project duration. Which technique is being used, and what is its primary trade-off?

Accepted Answer

Crashing; increases cost. Crashing adds resources to critical path activities, which increases cost but does not necessarily increase risk as much as fast-tracking.

Answer

Fast-tracking; increases cost

Answer

Crashing; increases risk

Answer

Fast-tracking; increases risk

Question 5

A project team discovers a problem that is currently happening and affecting project deliverables. The project manager needs to document this situation. Which document should be used to record this?

Accepted Answer

Issue log. An issue log is used to document current problems that have occurred, as opposed to risks which are uncertain future events.

Answer

Change log

Answer

Risk register

Answer

Lessons learned

Question 6

In a construction project, the foundation must be completed before the framing can begin. This is an example of which type of dependency?

Accepted Answer

Mandatory dependency. Mandatory dependencies, also known as hard logic, are inherent in the nature of the work and cannot be changed.

Answer

Resource constraint

Answer

External dependency

Answer

Discretionary dependency

Question 7

A project manager has identified a risk with a probability of 0.3 and an impact of 4 on a scale of 1-5. What is the risk score?

Accepted Answer

1.2. Risk score is calculated as probability × impact. Here, 0.3 × 4 = 1.2.

Answer

4.3

Answer

0.75

Answer

12

Question 8

Which document contains the deliverables, acceptance criteria, exclusions, assumptions, and constraints for a project?

Accepted Answer

Scope statement. The scope statement formally documents all these elements to define the project scope.

Answer

Work breakdown structure (WBS)

Answer

Project charter

Answer

Requirements traceability matrix

Question 9

A project team is performing quantitative risk analysis using a technique that runs thousands of simulations to determine the probability of completing the project on a specific date. Which technique is being used?

Accepted Answer

Monte Carlo simulation. Monte Carlo simulation uses repeated random sampling to model the probability of different outcomes, commonly used for schedule and cost risk analysis.

Answer

Sensitivity analysis

Answer

SWOT analysis

Answer

Decision tree analysis

Question 10

A project team is facing a critical issue that the project manager cannot resolve. According to best practices, what should the project manager do?

Accepted Answer

Escalate the issue. When an issue cannot be resolved at the project manager's level, it should be escalated to higher management or the appropriate authority.

Answer

Ignore the issue and hope it resolves

Answer

Close the project

Answer

Update the risk register

Question 11

A project has a constraint that a key piece of equipment must be sourced from a specific vendor due to organizational policy. This is an example of which type of constraint?

Accepted Answer

Technical constraint. Technical constraints are imposed technology choices or specifications, including sourcing from approved vendors.

Answer

External dependency

Answer

Mandatory dependency

Answer

Resource constraint

Question 12

During project planning, the team identifies that a key developer is only available 50% of the time. This is an example of which type of constraint?

Accepted Answer

Resource constraint. Resource constraints are limitations on the availability of resources, such as personnel, equipment, or materials.

Answer

Technical constraint

Answer

Schedule constraint

Answer

Cost constraint

Question 13

A project manager is updating the risk register. Which TWO fields are typically included in a risk register?

Accepted Answer

Trigger. Common risk register fields include risk ID, description, owner, probability, impact, risk score, response strategy, residual risk, and trigger.

Answer

Priority

Answer

Issue ID

Answer

Resolution date

Question 14

A project manager is reviewing change requests. Which THREE types of changes would be subject to integrated change control?

Accepted Answer

Schedule change. Change control applies to any change that affects the project baselines, including scope, schedule, cost, and quality.

Answer

Office supply order

Answer

Team member vacation request

Question 15

A project sponsor asks the project manager to accelerate the schedule. Which TWO schedule compression techniques could the project manager consider?

Accepted Answer

Fast-tracking. Fast-tracking and crashing are the two primary schedule compression techniques.

Answer

Monte Carlo simulation

Answer

Resource leveling

Answer

Scope reduction

Question 16

Which document formally defines the deliverables, acceptance criteria, exclusions, assumptions, and constraints of a project?

Accepted Answer

Scope statement. The scope statement documents the project's scope including deliverables, acceptance criteria, exclusions, assumptions, and constraints.

Answer

Work Breakdown Structure

Answer

Project charter

Answer

Question 17

A project team is creating a WBS. They ensure that every deliverable and work package is included and that the sum of the work at the lower levels equals the total work at the higher levels. Which principle are they applying?

Accepted Answer

100% rule. The 100% rule states that the WBS includes all work defined by the scope and that the sum of lower-level work equals the total work at higher levels.

Answer
