CompTIA PK0-005 Practice Test 15

Question 140

A release passes technical checks but fails stakeholder acceptance. Which caution is MOST directly relevant to the project manager's decision?

Testing only the repaired function cannot rule out side effects elsewhere
Developers' code completion is not a substitute for business acceptance
Passing unit tests alone is not proof the solution solves the user's need
A lessons-learned slide deck without follow-through rarely changes practice

Explanation

Correct Answer

Passing unit tests alone is not proof the solution solves the user's need. The underlying reason is that verification checks built requirements while validation checks intended use.

Incorrect Answers

This is a caution about regression testing, not the immediate risk in verification versus validation. Regression testing detects unintended impacts on existing behavior.

This is a caution about user acceptance tests, not the immediate risk in verification versus validation. User acceptance testing determines whether business needs are met.

This is a caution about retrospective learning, not the immediate risk in verification versus validation. Retrospectives improve how a team works, not just product feature scope.

Question 141

A patch fixes authentication but could break existing enrollment flows. Which project-management action BEST addresses this situation?

Rerun relevant existing tests after the change to detect regressions
Define outcome-based KPIs and measurable acceptance thresholds
Separate conformance verification from fitness-for-use validation
Run user acceptance testing against agreed business scenarios

Explanation

Correct Answer

Regression testing detects unintended impacts on existing behavior. Here, a patch fixes authentication but could break existing enrollment flows; the chosen action targets that failure. Verification: check unchanged workflows continue passing in a controlled test suite.

Incorrect Answers

This response addresses performance measures, but the stated decision concerns regression testing. Useful performance indicators measure progress toward defined objectives.

This response addresses verification versus validation, but the stated decision concerns regression testing. Verification checks built requirements while validation checks intended use.

This response addresses user acceptance tests, but the stated decision concerns regression testing. User acceptance testing determines whether business needs are met.

Question 142

The team follows this response: Rerun relevant existing tests after the change to detect regressions. Context: a patch fixes authentication but could break existing enrollment flows. Which evidence BEST verifies the intended outcome?

Verify improvement actions have owners and are tried in subsequent iterations
Obtain recorded acceptance from designated business owners
Check unchanged workflows continue passing in a controlled test suite
Confirm test evidence and business acceptance cover distinct criteria

Explanation

Correct Answer

Check unchanged workflows continue passing in a controlled test suite. That evidence tests the response to a patch fixes authentication but could break existing enrollment flows instead of an unrelated project condition.

Incorrect Answers

This check would validate retrospective learning, not the result required by the regression testing case. Retrospectives improve how a team works, not just product feature scope.

This check would validate user acceptance tests, not the result required by the regression testing case. User acceptance testing determines whether business needs are met.

This check would validate verification versus validation, not the result required by the regression testing case. Verification checks built requirements while validation checks intended use.

Question 143

A new API release may affect workflows that previously passed. Which principle MOST directly explains how the project should be managed?

Useful performance indicators measure progress toward defined objectives
Regression testing detects unintended impacts on existing behavior
User acceptance testing determines whether business needs are met
Retrospectives improve how a team works, not just product feature scope

Explanation

Correct Answer

Regression testing detects unintended impacts on existing behavior. The situation involves a new api release may affect workflows that previously passed, so this is the governing distinction.

Incorrect Answers

That principle concerns performance measures rather than the problem of regression testing. Useful performance indicators measure progress toward defined objectives.

That principle concerns user acceptance tests rather than the problem of regression testing. User acceptance testing determines whether business needs are met.

That principle concerns retrospective learning rather than the problem of regression testing. Retrospectives improve how a team works, not just product feature scope.

Question 144

Question 145

A PM reports hours worked but no measure of delivery value or quality. Which project-management action BEST addresses this situation?

Define outcome-based KPIs and measurable acceptance thresholds
Conduct a retrospective and assign actionable improvements
Rerun relevant existing tests after the change to detect regressions
Run user acceptance testing against agreed business scenarios

Explanation

Correct Answer

Useful performance indicators measure progress toward defined objectives. Here, a pm reports hours worked but no measure of delivery value or quality; the chosen action targets that failure. Verification: review performance measures against baselines and trend targets.

Incorrect Answers

This response addresses retrospective learning, but the stated decision concerns performance measures. Retrospectives improve how a team works, not just product feature scope.

This response addresses regression testing, but the stated decision concerns performance measures. Regression testing detects unintended impacts on existing behavior.

This response addresses user acceptance tests, but the stated decision concerns performance measures. User acceptance testing determines whether business needs are met.

Question 146

Useful performance indicators measure progress toward defined objectives
User acceptance testing determines whether business needs are met
Verification checks built requirements while validation checks intended use

Explanation

Correct Answer

Useful performance indicators measure progress toward defined objectives. The situation involves executives need to know if support response targets and outcomes are met, so this is the governing distinction.

Developers' code completion is not a substitute for business acceptance
High activity volume does not necessarily indicate high customer value
Passing unit tests alone is not proof the solution solves the user's need
