PK0-005 Practice Test 48 — 15 Questions

Question 1

During a quality audit, the team identifies that defects are concentrated in a few areas. The project manager decides to use a Pareto chart. Which TWO statements are true about Pareto charts?

Accepted Answer

They are based on the 80/20 rule.. Pareto charts are based on the 80/20 rule, showing that 80% of effects come from 20% of causes. Bars are arranged in descending order of frequency. Control limits are for control charts. Cause-and-effect relationships are shown in fishbone diagrams.

Answer

The bars are arranged in ascending order of frequency.

Answer

They show cause-and-effect relationships.

Answer

They display control limits to identify variations.

Question 2

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 3

Which project document formally authorizes the project and provides the project manager with the authority to apply organizational resources?

Accepted Answer

Project charter. The project charter is the document that formally authorizes the project and gives the project manager authority. The project management plan describes how the project will be executed. The scope statement defines the scope. The stakeholder register lists stakeholders.

Answer

Stakeholder register

Answer

Project management plan

Answer

Scope statement

Question 4

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 5

A project team is using Jira for an Agile project. Which TWO artefacts are typically managed within Jira for sprint planning and tracking? (Choose two.)

Accepted Answer

Product backlog. Jira supports product backlog (epics, stories, tasks) and sprint backlog (selected items for current sprint). Velocity is a metric, not an artefact; burndown chart is a visualization; stakeholder register is not typically in Jira.

Answer

Burndown chart

Answer

Stakeholder register

Answer

Velocity

Question 6

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

Question 7

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 8

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 9

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 10

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 11

A project manager is reviewing earned value data: PV = $150,000, EV = $120,000, AC = $130,000. Which THREE statements are correct?

Accepted Answer

The schedule performance index (SPI) is 0.8.. SV = EV - PV = 120,000 - 150,000 = -30,000 (negative, behind schedule). CV = EV - AC = 120,000 - 130,000 = -10,000 (negative, over budget). SPI = EV/PV = 0.8 (less than 1, behind schedule). CPI = EV/AC = 0.923 (less than 1, over budget).

Answer

The cost performance index (CPI) is 1.08.

Answer

The project is under budget.

Question 12

In an Agile project, the team uses story points to estimate effort. During sprint planning, they select user stories from the product backlog and assign them to the sprint. What is the resulting list of items committed for the sprint called?

Accepted Answer

Sprint backlog. The sprint backlog is the set of product backlog items selected for the sprint, along with a plan for delivering them. The product backlog is the full list of requirements; burndown/burnup charts track progress.

Answer

Product backlog

Answer

Burndown chart

Answer

Burnup chart

Question 13

During a project, the project manager calculates the following: Earned Value (EV) = $50,000, Planned Value (PV) = $60,000, Actual Cost (AC) = $55,000. Which statement accurately describes the project's performance?

Accepted Answer

The project is behind schedule and over budget.. Schedule Variance (SV) = EV - PV = $50,000 - $60,000 = -$10,000, indicating behind schedule. Cost Variance (CV) = EV - AC = $50,000 - $55,000 = -$5,000, indicating over budget.

Answer

The project is ahead of schedule and under budget.

Answer

The project is ahead of schedule and over budget.

Answer

The project is behind schedule and under budget.

Question 14

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 15

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
