CompTIA PK0-005 Practice Test 45

Question 440

An initiative expects $300,000 in total benefits against $200,000 in total investment over the same period. What is ROI when defined as net gain divided by investment?

150%
33.3%
100%
50%

Explanation

Correct Answer

Net gain is $300,000 − $200,000 = $100,000; divided by $200,000 invested gives 0.50, or 50%.

Incorrect Answers

150% is gross benefit divided by investment, not net gain divided by investment.

33.3% divides net gain by gross benefits rather than investment.

100% overstates the net return relative to the stated cost.

Question 441

An approved schedule baseline sets completion on 30 September, but the forecast now shows 10 October. Which date should remain the baseline until an authorized rebaseline occurs?

10 October
The midpoint of the two dates
The latest date reported in team chat
30 September

Explanation

Correct Answer

30 September remains the approved baseline; the 10 October forecast is a variance until change control authorizes a revised baseline.

Incorrect Answers

10 October is the current forecast, not automatically the authorized baseline.

A mathematical midpoint has no governance basis for selecting a baseline.

An informal date cannot supersede the approved baseline without authority.

Question 442

A PM needs to show planned task durations and dependencies on a calendar. Which project-management action BEST addresses this situation?

Use a Gantt chart to visualize activities, dependencies and timing
Provide a concise periodic status report with scope, progress, issues and forecast
Record reproducible defects with severity, owner and fix verification
Maintain change requests, decisions, impact and implementation status in a change log

Explanation

Correct Answer

Gantt charts display planned work over time and dependency relationships. Here, a pm needs to show planned task durations and dependencies on a calendar; the chosen action targets that failure. Verification: check critical tasks and milestones appear against the baseline calendar.

Incorrect Answers

This response addresses project status report, but the stated decision concerns gantt chart. Status reporting conveys decisions needed and material project variance.

This response addresses defect tracking, but the stated decision concerns gantt chart. Defect logs manage identifiable product faults and resolution evidence.

This response addresses change log, but the stated decision concerns gantt chart. A change log provides auditable history of baseline modifications.

Question 443

The team follows this response: Use a Gantt chart to visualize activities, dependencies and timing. Context: a pm needs to show planned task durations and dependencies on a calendar. Which evidence BEST verifies the intended outcome?

Verify report claims reconcile to schedule, budget and issue sources
Recalculate expected duration using the agreed three-point estimate method
Check critical tasks and milestones appear against the baseline calendar
Confirm current status and corrective work are visible until resolution

Explanation

Correct Answer

Check critical tasks and milestones appear against the baseline calendar. That evidence tests the response to a pm needs to show planned task durations and dependencies on a calendar instead of an unrelated project condition.

Incorrect Answers

This check would validate project status report, not the result required by the gantt chart case. Status reporting conveys decisions needed and material project variance.

This check would validate pert estimation, not the result required by the gantt chart case. PERT can model an uncertain task using optimistic, most likely and pessimistic estimates.

This check would validate issue log, not the result required by the gantt chart case. An issue log tracks existing problems that require intervention.

Question 444

Sponsors ask for a date-oriented view of overlapping activities. Which principle MOST directly explains how the project should be managed?

Gantt charts display planned work over time and dependency relationships
Status reporting conveys decisions needed and material project variance
An issue log tracks existing problems that require intervention
A risk register manages uncertain future events and response commitments

Explanation

Correct Answer

Gantt charts display planned work over time and dependency relationships. The situation involves sponsors ask for a date-oriented view of overlapping activities, so this is the governing distinction.

Incorrect Answers

That principle concerns project status report rather than the problem of gantt chart. Status reporting conveys decisions needed and material project variance.

That principle concerns issue log rather than the problem of gantt chart. An issue log tracks existing problems that require intervention.

That principle concerns risk register rather than the problem of gantt chart. A risk register manages uncertain future events and response commitments.

Question 445

Sponsors ask for a date-oriented view of overlapping activities. Which caution is MOST directly relevant to the project manager's decision?

Logged hours alone do not prove a deliverable meets quality criteria
One optimistic estimate is not equivalent to a three-point expectation
A Gantt bar is not proof the work is complete until progress is recorded
Moving a card to done does not automatically validate its acceptance criteria

Explanation

Correct Answer

A Gantt bar is not proof the work is complete until progress is recorded. The underlying reason is that gantt charts display planned work over time and dependency relationships.

Incorrect Answers

This is a caution about time tracking, not the immediate risk in gantt chart. Time logs support effort, utilization and contract cost review.

This is a caution about pert estimation, not the immediate risk in gantt chart. PERT can model an uncertain task using optimistic, most likely and pessimistic estimates.

This is a caution about task board, not the immediate risk in gantt chart. A task board visualizes workflow and accountability.

Question 446

A schedule slips because teams do not understand predecessor relationships. Which project-management action BEST addresses this situation?

Construct a project network diagram of activity dependencies
Provide a concise periodic status report with scope, progress, issues and forecast
Track the active issue, urgency, owner and resolution path in an issue log
Record reproducible defects with severity, owner and fix verification

Explanation

Correct Answer

Network diagrams expose logic and sequencing among project activities. Here, a schedule slips because teams do not understand predecessor relationships; the chosen action targets that failure. Verification: validate predecessor paths and potential critical sequences.

Incorrect Answers

This response addresses project status report, but the stated decision concerns network diagram. Status reporting conveys decisions needed and material project variance.

This response addresses issue log, but the stated decision concerns network diagram. An issue log tracks existing problems that require intervention.

This response addresses defect tracking, but the stated decision concerns network diagram. Defect logs manage identifiable product faults and resolution evidence.

Question 447

The team follows this response: Construct a project network diagram of activity dependencies. Context: a schedule slips because teams do not understand predecessor relationships. Which evidence BEST verifies the intended outcome?

Check current risk ratings, triggers and response status are traceable
Validate predecessor paths and potential critical sequences
Recalculate expected duration using the agreed three-point estimate method
Check each gate date reconciles to the detailed schedule

Explanation

Correct Answer

Validate predecessor paths and potential critical sequences. That evidence tests the response to a schedule slips because teams do not understand predecessor relationships instead of an unrelated project condition.

Incorrect Answers

This check would validate risk register, not the result required by the network diagram case. A risk register manages uncertain future events and response commitments.

This check would validate pert estimation, not the result required by the network diagram case. PERT can model an uncertain task using optimistic, most likely and pessimistic estimates.

This check would validate milestone chart, not the result required by the network diagram case. Milestone charts emphasize key checkpoints rather than complete task effort.

Question 448

An integration has parallel tasks with dependencies not visible in a flat checklist. Which principle MOST directly explains how the project should be managed?

Dashboards summarize reliable project performance for quick decisions
PERT can model an uncertain task using optimistic, most likely and pessimistic estimates
Network diagrams expose logic and sequencing among project activities
Milestone charts emphasize key checkpoints rather than complete task effort

Explanation

Correct Answer

Network diagrams expose logic and sequencing among project activities. The situation involves an integration has parallel tasks with dependencies not visible in a flat checklist, so this is the governing distinction.

Incorrect Answers

That principle concerns project dashboard rather than the problem of network diagram. Dashboards summarize reliable project performance for quick decisions.

That principle concerns pert estimation rather than the problem of network diagram. PERT can model an uncertain task using optimistic, most likely and pessimistic estimates.

That principle concerns milestone chart rather than the problem of network diagram. Milestone charts emphasize key checkpoints rather than complete task effort.

Question 449

An integration has parallel tasks with dependencies not visible in a flat checklist. Which caution is MOST directly relevant to the project manager's decision?

A possible future threat should not be mislabeled as an ongoing incident
A Gantt bar is not proof the work is complete until progress is recorded
An issue log is not an exact substitute for a risk register
Sorting tasks by date alone does not identify all logical dependencies

Explanation

Correct Answer

Sorting tasks by date alone does not identify all logical dependencies. The underlying reason is that network diagrams expose logic and sequencing among project activities.

Incorrect Answers

This is a caution about issue log, not the immediate risk in network diagram. An issue log tracks existing problems that require intervention.

This is a caution about gantt chart, not the immediate risk in network diagram. Gantt charts display planned work over time and dependency relationships.

This is a caution about risk register, not the immediate risk in network diagram. A risk register manages uncertain future events and response commitments.

Question 450

A new program has a list of concerns without owners or responses. Which project-management action BEST addresses this situation?

Use a Gantt chart to visualize activities, dependencies and timing
Maintain a risk register with probability, impact, ownership and planned responses
Use a shared task board with clear work states and owners
Use time tracking linked to authorized activities and invoicing rules

Explanation

Correct Answer

A risk register manages uncertain future events and response commitments. Here, a new program has a list of concerns without owners or responses; the chosen action targets that failure. Verification: check current risk ratings, triggers and response status are traceable.

Incorrect Answers

This response addresses gantt chart, but the stated decision concerns risk register. Gantt charts display planned work over time and dependency relationships.

This response addresses task board, but the stated decision concerns risk register. A task board visualizes workflow and accountability.

This response addresses time tracking, but the stated decision concerns risk register. Time logs support effort, utilization and contract cost review.
