Quick Answer
The answer is a Gantt chart. This tool is correct because it visually maps project tasks along a timeline, showing dependencies, durations, and resource assignments, while explicitly highlighting the critical path—the longest sequence of dependent tasks that determines the project’s minimum duration. When a task is delayed, the Gantt chart allows the project manager to dynamically adjust the schedule and immediately see the impact on the critical path, making it essential for schedule management and impact analysis. On the CompTIA Project+ PK0-005 exam, this question tests your ability to distinguish between scheduling tools; a common trap is confusing the Gantt chart with a network diagram, which shows task logic but lacks the timeline and resource view. Remember the memory tip: “Gantt gives the glance”—it’s the only tool that combines a timeline, dependencies, and the critical path in one visual, so you can track delays at a glance.
This PK0-005 practice question tests your understanding of tools and documentation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A project manager is using a tool to track project tasks, dependencies, and resource assignments. The team needs to see the critical path and adjust schedules when tasks are delayed. Which tool should the project manager use?
Pareto chart
Why wrong: Pareto chart prioritizes causes of problems, not project schedules.
RACI matrix
Why wrong: RACI matrix defines roles and responsibilities, not task scheduling.
Gantt chart
Gantt charts display tasks, durations, dependencies, and critical path, enabling schedule adjustments.
Kanban board
Why wrong: Kanban boards manage workflow and WIP limits, not project schedules or critical path.

Correct answer & explanation
Gantt chart
The Gantt chart is the correct tool because it visually displays project tasks, their dependencies, durations, and resource assignments along a timeline. It explicitly shows the critical path (the longest sequence of dependent tasks) and allows the project manager to adjust schedules dynamically when tasks are delayed, making it ideal for schedule management and impact analysis.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Pareto chart
Why it's wrong here
Pareto chart prioritizes causes of problems, not project schedules.
RACI matrix
Why it's wrong here
RACI matrix defines roles and responsibilities, not task scheduling.

Kanban board
Why it's wrong here
Kanban boards manage workflow and WIP limits, not project schedules or critical path.
Common exam traps
The trap here is that candidates confuse a Kanban board's visual workflow management with the scheduling and dependency-tracking capabilities of a Gantt chart, leading them to pick Kanban when the question explicitly requires critical path and schedule adjustment features.
Detailed technical explanation
A Gantt chart uses a horizontal bar chart where each bar represents a task's start and end dates, with dependency arrows (e.g., finish-to-start) linking tasks. The critical path is computed by identifying the longest path through the network diagram, where any delay on a critical task directly extends the project's finish date; modern tools like Microsoft Project or Primavera P6 automatically recalculate the critical path when task durations or dependencies change. In a real-world scenario, if a non-critical task slips, the Gantt chart shows float (slack) remaining, but if a critical task is delayed, the project end date shifts, triggering replanning.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

Variation 1. A project manager needs to track the start and end dates of tasks as well as dependencies. Which tool should be used?
easyWhy A: A Gantt chart is the correct tool because it visually displays task start and end dates along a timeline, and it can explicitly show dependencies between tasks using arrows or linking lines. This makes it ideal for project scheduling and tracking progress against planned dates.
