CompTIA PK0-005 Practice Test 56

Question 550

A PM suspects testing effort increases as defect escapes decrease. Which project-management action BEST addresses this situation?

Plot paired quantitative observations on a scatter diagram
Track accepted story points per sprint and use stable trend for planning
Use a burnup chart showing completed work and total scope as separate lines
Use a burndown chart plotting estimated work remaining over iteration time

Explanation

Correct Answer

Scatter diagrams visualize relationships between two numeric variables. Here, a pm suspects testing effort increases as defect escapes decrease; the chosen action targets that failure. Verification: check direction, strength and outliers before inferring association.

Incorrect Answers

This response addresses velocity chart, but the stated decision concerns scatter plot. Velocity reflects historical completed work in a particular team context.

This response addresses burnup chart, but the stated decision concerns scatter plot. Burnup charts make scope growth visible alongside cumulative completion.

This response addresses burndown chart, but the stated decision concerns scatter plot. Burndown charts show remaining scope against time.

Question 551

The team follows this response: Plot paired quantitative observations on a scatter diagram. Context: a pm suspects testing effort increases as defect escapes decrease. Which evidence BEST verifies the intended outcome?

Inspect values and patterns relative to established statistical control boundaries
Review rolling completed points rather than planned points alone
Inspect temporal trends and sustained shifts in the measure
Check direction, strength and outliers before inferring association

Explanation

Correct Answer

Check direction, strength and outliers before inferring association. That evidence tests the response to a pm suspects testing effort increases as defect escapes decrease instead of an unrelated project condition.

Incorrect Answers

This check would validate control chart, not the result required by the scatter plot case. Control charts distinguish expected process variation from special causes.

This check would validate velocity chart, not the result required by the scatter plot case. Velocity reflects historical completed work in a particular team context.

This check would validate run chart, not the result required by the scatter plot case. A run chart shows variation over time without requiring control limits.

Question 552

Two numeric measures may be related but team only has isolated anecdotes. Which principle MOST directly explains how the project should be managed?

Control charts distinguish expected process variation from special causes
Pareto charts rank categories to focus improvement on major contributors
Burnup charts make scope growth visible alongside cumulative completion
Scatter diagrams visualize relationships between two numeric variables

Explanation

Correct Answer

Scatter diagrams visualize relationships between two numeric variables. The situation involves two numeric measures may be related but team only has isolated anecdotes, so this is the governing distinction.

Incorrect Answers

That principle concerns control chart rather than the problem of scatter plot. Control charts distinguish expected process variation from special causes.

That principle concerns pareto chart rather than the problem of scatter plot. Pareto charts rank categories to focus improvement on major contributors.

That principle concerns burnup chart rather than the problem of scatter plot. Burnup charts make scope growth visible alongside cumulative completion.

Question 553

Two numeric measures may be related but team only has isolated anecdotes. Which caution is MOST directly relevant to the project manager's decision?

An observed point above the mean is not automatically out of control
A histogram is not best suited to showing named defect categories by rank
Correlation alone does not establish that one variable caused the other
A cause written on the diagram is a hypothesis, not confirmed root cause

Explanation

Correct Answer

Correlation alone does not establish that one variable caused the other. The underlying reason is that scatter diagrams visualize relationships between two numeric variables.

Incorrect Answers

This is a caution about control chart, not the immediate risk in scatter plot. Control charts distinguish expected process variation from special causes.

This is a caution about histogram, not the immediate risk in scatter plot. Histograms display frequencies across ranges of numeric values.

This is a caution about fishbone diagram, not the immediate risk in scatter plot. Fishbone diagrams organize potential contributors to a defined problem.

Question 554

A deployment team needs to see distribution of API response times. Which project-management action BEST addresses this situation?

Build an Ishikawa cause-and-effect diagram grouping hypotheses
Track accepted story points per sprint and use stable trend for planning
Use a burnup chart showing completed work and total scope as separate lines
Use a histogram with value intervals and observation frequencies

Explanation

Correct Answer

Histograms display frequencies across ranges of numeric values. Here, a deployment team needs to see distribution of api response times; the chosen action targets that failure. Verification: check bins reveal spread, skew and concentration in the recorded data.

Incorrect Answers

This response addresses fishbone diagram, but the stated decision concerns histogram. Fishbone diagrams organize potential contributors to a defined problem.

This response addresses velocity chart, but the stated decision concerns histogram. Velocity reflects historical completed work in a particular team context.

This response addresses burnup chart, but the stated decision concerns histogram. Burnup charts make scope growth visible alongside cumulative completion.

Question 555

The team follows this response: Use a histogram with value intervals and observation frequencies. Context: a deployment team needs to see distribution of api response times. Which evidence BEST verifies the intended outcome?

Check whether the dominant categories account for most observed loss
Check the gap between completed effort and current total requirement
Verify each suspected cause is tested with evidence before corrective action
Check bins reveal spread, skew and concentration in the recorded data

Explanation

Correct Answer

Check bins reveal spread, skew and concentration in the recorded data. That evidence tests the response to a deployment team needs to see distribution of api response times instead of an unrelated project condition.

Incorrect Answers

This check would validate pareto chart, not the result required by the histogram case. Pareto charts rank categories to focus improvement on major contributors.

This check would validate burnup chart, not the result required by the histogram case. Burnup charts make scope growth visible alongside cumulative completion.

This check would validate fishbone diagram, not the result required by the histogram case. Fishbone diagrams organize potential contributors to a defined problem.

Question 556

A quality analyst needs frequency counts for continuous measured durations. Which principle MOST directly explains how the project should be managed?

Control charts distinguish expected process variation from special causes
Pareto charts rank categories to focus improvement on major contributors
Histograms display frequencies across ranges of numeric values
Fishbone diagrams organize potential contributors to a defined problem

Explanation

Correct Answer

Histograms display frequencies across ranges of numeric values. The situation involves a quality analyst needs frequency counts for continuous measured durations, so this is the governing distinction.

That principle concerns fishbone diagram rather than the problem of histogram. Fishbone diagrams organize potential contributors to a defined problem.

Question 557

A quality analyst needs frequency counts for continuous measured durations. Which caution is MOST directly relevant to the project manager's decision?

A single remaining-work line cannot distinguish delivery from scope additions as clearly
A histogram is not best suited to showing named defect categories by rank
An observed point above the mean is not automatically out of control
A decision tree is not proof of outcome certainty when probabilities are estimates

Explanation

Correct Answer

A histogram is not best suited to showing named defect categories by rank. The underlying reason is that histograms display frequencies across ranges of numeric values.

Incorrect Answers

This is a caution about burnup chart, not the immediate risk in histogram. Burnup charts make scope growth visible alongside cumulative completion.

This is a caution about control chart, not the immediate risk in histogram. Control charts distinguish expected process variation from special causes.

This is a caution about decision tree, not the immediate risk in histogram. Decision trees structure sequential choices under uncertainty.

Question 558

A sprint manager wants to know how much work remains each day. Which project-management action BEST addresses this situation?

Use a Pareto chart ranking defect categories by frequency or impact
Build an Ishikawa cause-and-effect diagram grouping hypotheses
Use a burndown chart plotting estimated work remaining over iteration time
Plot paired quantitative observations on a scatter diagram

Explanation

Correct Answer

Burndown charts show remaining scope against time. Here, a sprint manager wants to know how much work remains each day; the chosen action targets that failure. Verification: compare remaining-work trend against planned completion trajectory.

Incorrect Answers

This response addresses pareto chart, but the stated decision concerns burndown chart. Pareto charts rank categories to focus improvement on major contributors.

This response addresses fishbone diagram, but the stated decision concerns burndown chart. Fishbone diagrams organize potential contributors to a defined problem.

This response addresses scatter plot, but the stated decision concerns burndown chart. Scatter diagrams visualize relationships between two numeric variables.
