PK0-005 Practice Test 3 — 25 Questions

Question 1

During a quality audit, the project team discovers that 80% of customer complaints are caused by 20% of the defect types. Which quality tool should the project manager use to present this data and prioritize corrective actions?

Accepted Answer

Pareto chart. A Pareto chart is based on the 80/20 rule and is used to highlight the most significant factors causing defects.

Answer

Scatter diagram

Answer

Control chart

Answer

Cause-and-effect diagram

Question 2

A project manager is creating a document that formally authorizes the project and assigns the project manager. Which document is this?

Accepted Answer

Project charter. The project charter is the document that formally authorizes a project and provides the project manager with authority to apply organizational resources.

Answer

Risk register

Answer

Project management plan

Answer

WBS

Question 3

During a software development project, the team estimates story points using planning poker. A story is estimated at 8 points, while a similar story was previously estimated at 5 points. What is the primary reason for using relative sizing with story points?

Accepted Answer

To compare the effort of stories relative to each other. Story points are a relative measure of effort; the exact values are less important than the relative comparison. Planning poker facilitates consensus.

Answer

To assign story points based on the developer’s skill level

Answer

To track the number of story points completed per day

Answer

To calculate exact hours needed for each story

Question 4

A project manager is evaluating the project's performance using EVM. PV = $50,000, EV = $45,000, AC = $55,000. Which of the following is true?

Accepted Answer

The project is over budget and behind schedule.. SV = EV - PV = -$5,000 (behind schedule). CV = EV - AC = -$10,000 (over budget). CPI = EV/AC = 0.818, SPI = EV/PV = 0.9.

Answer

The project is under budget and ahead of schedule.

Answer

The project is over budget but ahead of schedule.

Answer

The project is under budget but behind schedule.

Question 5

Which TWO documents are typically found in a project's procurement management plan?

Accepted Answer

Request for Proposal (RFP). Procurement documents include SOW (Statement of Work) and RFP (Request for Proposal). The project charter and WBS are not procurement-specific; the risk register is a risk document.

Answer

Risk register

Answer

Project charter

Answer

Work Breakdown Structure (WBS)

Question 6

In an agile project using Jira, the product owner wants to prioritize the work for the next iteration. Which document or artefact should they refer to?

Accepted Answer

Question 8

A project team uses a tool that shows only major events or deadlines, such as the start and end of phases. Which type of chart are they using?

Accepted Answer

Milestone chart. A milestone chart displays key events (milestones) along a timeline. Gantt charts show all tasks, network diagrams show dependencies, and burndown charts track remaining work over time.

Answer

Gantt chart

Answer

Network diagram

Answer

Burndown chart

Question 9

A project manager is analyzing quality control data and wants to identify whether process variation is due to special causes or common causes. Which TWO tools would be most helpful?

Accepted Answer

Run chart. Control charts (with UCL/LCL) distinguish between special and common cause variation. Run charts can also show trends but may not have control limits. Cause-and-effect diagrams identify root causes, Pareto charts prioritize, histograms show distribution but not special causes.

Answer

Histogram

Answer

Cause-and-effect diagram

Answer

Pareto chart

Question 10

A project manager is reviewing the communication plan and notices that stakeholder A is listed as 'Responsible' for a task in the RACI matrix. According to RACI, what does 'Responsible' mean?

Accepted Answer

The person who performs the work. In RACI, 'Responsible' means the person who does the work to complete the task. 'Accountable' is the person who signs off.

Answer

The person who provides expert input

Answer

The person who needs to be informed of progress

Answer

The person who must approve the task

Question 11

An agile team has a velocity of 30 story points per sprint. The product backlog contains 120 story points of work. How many sprints are needed to complete the backlog assuming no changes?

Accepted Answer

4 sprints. Number of sprints = total story points / velocity = 120 / 30 = 4 sprints.

Answer

6 sprints

Answer

3 sprints

Answer

5 sprints

Question 12

A project manager is reviewing a control chart for a manufacturing process. Several data points fall outside the upper control limit (UCL). What type of variation do these points indicate?

Accepted Answer

Special cause variation. Data points outside control limits indicate special cause variation, which is unusual and not part of the normal process. Common cause variation is inherent and stays within limits. Random variation is not a standard term; it is similar to common cause. Assignable cause is another term for special cause, but the question asks for the type of variation, not the cause.

Answer

Common cause variation

Answer

Assignable cause

Answer

Random variation

Question 13

A project manager is reviewing quality control results and sees a pattern of increasing defects over time. Which THREE quality tools would be most appropriate to analyze this situation?

Accepted Answer

Histogram. Run chart shows trends over time. Histogram shows distribution. Control chart shows variations and trends. Pareto prioritizes causes but not trends. Fishbone is root cause analysis.

Answer

Pareto chart

Answer

Fishbone diagram

Question 14

In an agile project, the team is defining the 'Definition of Done' (DoD). Which TWO statements are typically included in a good DoD?

Accepted Answer

Unit tests have been written and passed.. DoD includes criteria that must be met for a user story to be considered complete, such as code review, testing, and documentation. Prioritizing the backlog is not part of DoD; that's product owner role. Assigning story points is done during estimation.

Answer

The product owner has prioritized the backlog.

Answer

Story points have been assigned to the story.

Answer

The story has been added to the product backlog.

Question 15

Which project scheduling tool displays tasks as horizontal bars on a timeline, shows dependencies between tasks, and can highlight the critical path?

Accepted Answer

Gantt chart. A Gantt chart uses horizontal bars to represent tasks, shows dependencies with arrows, and can highlight the critical path. A network diagram uses nodes and arrows but not horizontal bars. A milestone chart only shows key events. A Kanban board visualizes workflow columns.

Answer

Kanban board

Answer

Network diagram

Answer

Milestone chart

Question 16

During sprint planning, the team uses a technique where each member privately selects a card representing a number of story points for a user story. After revealing, they discuss discrepancies. This technique is known as:

Accepted Answer

Planning poker. Planning poker is an agile estimation technique where team members use numbered cards to vote on story point estimates. Pairs programming is a development practice, not estimation. Delphi technique is a consensus method but typically anonymous and iterative without cards. T-shirt sizing is a relative sizing method but does not involve simultaneous card reveal.

Answer

Pairs programming

Answer

T-shirt sizing

Answer

Delphi technique

Question 17

A project manager notices that the actual cost (AC) is $50,000, the earned value (EV) is $45,000, and the planned value (PV) is $55,000. Which statement is true regarding schedule and cost performance?

Accepted Answer

The project is behind schedule and over budget.. Schedule variance (SV) = EV - PV = $45,000 - $55,000 = -$10,000 (negative, behind schedule). Cost variance (CV) = EV - AC = $45,000 - $50,000 = -$5,000 (negative, over budget).

Answer

The project is ahead of schedule and over budget.

Answer

The project is behind schedule and under budget.

Answer

The project is ahead of schedule and under budget.

Question 18

A project manager uses a diagram to identify the most frequent causes of defects in a process. The diagram displays bars in descending order and a cumulative line. Which quality tool is being used?

Accepted Answer

Pareto chart. A Pareto chart is a bar chart where bars are ordered from highest to lowest frequency, often with a cumulative line, to highlight the 'vital few' causes (80/20 rule). A fishbone diagram shows potential causes but not frequency. A control chart tracks variation over time. A scatter diagram shows correlation between two variables.

Answer

Fishbone diagram

Answer

Scatter diagram

Answer

Control chart

Question 19

A project team is using a tool to track user stories, epics, and bugs within sprints. The tool allows the team to view work in columns such as 'To Do', 'In Progress', and 'Done'. Which tool feature is being described?

Accepted Answer

Kanban board. A Kanban board visualizes workflow with columns representing stages. A Gantt chart uses a timeline. A burndown chart tracks remaining work. A product backlog is a list of items, not a board with columns.

Answer

Gantt chart view

Answer

Product backlog

Answer

Burndown chart

Question 20

A project has a budget at completion (BAC) of $200,000. After 3 months, the earned value (EV) is $80,000, and the actual cost (AC) is $100,000. What is the estimate at completion (EAC) assuming the cost performance index (CPI) will remain the same for the remainder of the project?

Accepted Answer

$250,000. CPI = EV / AC = $80,000 / $100,000 = 0.8. The formula EAC = BAC / CPI is used when current cost performance is expected to continue. EAC = $200,000 / 0.8 = $250,000.

Answer

$220,000

Answer

$300,000

Answer

$200,000
