CompTIA PK0-005 Practice Test 13

Question 120

An application deployment must follow final security approval. Which caution is MOST directly relevant to the project manager's decision?

A visual order on a Gantt chart is not proof the dependency is enforced
A delay on a noncritical task with float need not delay final delivery
One team's story point is not necessarily comparable to another team's hour
A forecast change alone is not automatically authority to erase the baseline

Explanation

Correct Answer

A visual order on a Gantt chart is not proof the dependency is enforced. The underlying reason is that finish-to-start enforces ordered completion before dependent work starts.

Incorrect Answers

This is a caution about critical path impact, not the immediate risk in finish-to-start dependency. Critical path activities govern the earliest possible completion date.

This is a caution about agile estimation, not the immediate risk in finish-to-start dependency. Story points express relative effort and uncertainty within a team.

This is a caution about baseline revision, not the immediate risk in finish-to-start dependency. Baseline control distinguishes approved commitments from current forecasts.

Question 121

Two critical tasks simultaneously require one unavailable database engineer. Which project-management action BEST addresses this situation?

Recalculate critical path and forecast milestone impact from the delay
Model the required finish-to-start predecessor relationship
Resolve resource over-allocation by sequencing or changing assignments
Use relative story estimation and capacity forecasts for iterative planning

Explanation

Correct Answer

Resource leveling may change activity dates to match capacity. Here, two critical tasks simultaneously require one unavailable database engineer; the chosen action targets that failure. Verification: review resource loading to confirm no individual is double-booked.

Incorrect Answers

This response addresses critical path impact, but the stated decision concerns resource leveling. Critical path activities govern the earliest possible completion date.

This response addresses finish-to-start dependency, but the stated decision concerns resource leveling. Finish-to-start enforces ordered completion before dependent work starts.

This response addresses agile estimation, but the stated decision concerns resource leveling. Story points express relative effort and uncertainty within a team.

Question 122

The team follows this response: Resolve resource over-allocation by sequencing or changing assignments. Context: two critical tasks simultaneously require one unavailable database engineer. Which evidence BEST verifies the intended outcome?

Verify recalculated finish date and zero-float tasks are documented
Review resource loading to confirm no individual is double-booked
Confirm reserve assumptions and usage triggers are documented
Check velocity trends rather than treating points as universal labor hours

Explanation

Correct Answer

Review resource loading to confirm no individual is double-booked. That evidence tests the response to two critical tasks simultaneously require one unavailable database engineer instead of an unrelated project condition.

Incorrect Answers

This check would validate critical path impact, not the result required by the resource leveling case. Critical path activities govern the earliest possible completion date.

This check would validate estimation reserve, not the result required by the resource leveling case. Contingency reserves address identified variation within a controlled plan.

This check would validate agile estimation, not the result required by the resource leveling case. Story points express relative effort and uncertainty within a team.

Question 123

A schedule assumes a shared technician works full time on parallel activities. Which principle MOST directly explains how the project should be managed?

Critical path activities govern the earliest possible completion date
Story points express relative effort and uncertainty within a team
Contingency reserves address identified variation within a controlled plan
Resource leveling may change activity dates to match capacity

Explanation

Correct Answer

Resource leveling may change activity dates to match capacity. The situation involves a schedule assumes a shared technician works full time on parallel activities, so this is the governing distinction.

Incorrect Answers

That principle concerns critical path impact rather than the problem of resource leveling. Critical path activities govern the earliest possible completion date.

That principle concerns agile estimation rather than the problem of resource leveling. Story points express relative effort and uncertainty within a team.

That principle concerns estimation reserve rather than the problem of resource leveling. Contingency reserves address identified variation within a controlled plan.

Question 124

A schedule assumes a shared technician works full time on parallel activities. Which caution is MOST directly relevant to the project manager's decision?

A visual order on a Gantt chart is not proof the dependency is enforced
One team's story point is not necessarily comparable to another team's hour
A forecast change alone is not automatically authority to erase the baseline
An unbounded resource plan is not executable merely because task durations add up

Explanation

Correct Answer

An unbounded resource plan is not executable merely because task durations add up. The underlying reason is that resource leveling may change activity dates to match capacity.

Incorrect Answers

This is a caution about finish-to-start dependency, not the immediate risk in resource leveling. Finish-to-start enforces ordered completion before dependent work starts.

This is a caution about agile estimation, not the immediate risk in resource leveling. Story points express relative effort and uncertainty within a team.

This is a caution about baseline revision, not the immediate risk in resource leveling. Baseline control distinguishes approved commitments from current forecasts.

Question 125

An uncertain network migration estimate excludes any contingency. Which project-management action BEST addresses this situation?

Use relative story estimation and capacity forecasts for iterative planning
Recalculate critical path and forecast milestone impact from the delay
Rebaseline only after authorized substantive changes, retaining variance history
Add a justified contingency buffer tied to identified uncertainty

Explanation

Correct Answer

Contingency reserves address identified variation within a controlled plan. Here, an uncertain network migration estimate excludes any contingency; the chosen action targets that failure. Verification: confirm reserve assumptions and usage triggers are documented.

Incorrect Answers

This response addresses agile estimation, but the stated decision concerns estimation reserve. Story points express relative effort and uncertainty within a team.

This response addresses critical path impact, but the stated decision concerns estimation reserve. Critical path activities govern the earliest possible completion date.

This response addresses baseline revision, but the stated decision concerns estimation reserve. Baseline control distinguishes approved commitments from current forecasts.

Question 126

The team follows this response: Add a justified contingency buffer tied to identified uncertainty. Context: an uncertain network migration estimate excludes any contingency. Which evidence BEST verifies the intended outcome?

Confirm reserve assumptions and usage triggers are documented
Check the successor starts only after the predecessor is complete
Compare approved baseline versions and decision records against the forecast
Review resource loading to confirm no individual is double-booked

Explanation

Correct Answer

Confirm reserve assumptions and usage triggers are documented. That evidence tests the response to an uncertain network migration estimate excludes any contingency instead of an unrelated project condition.

Incorrect Answers
