質問 # 262
Given the following chart showing committed work (orange) vs. actual work completed (blue) across 10 sprints:
Which of the following best describes the team's performance?
- A. The team understands its velocity and is planning in an accurate manner.
- B. The team is doing more work than planned.
- C. The team's velocity is getting better.
- D. The team needs to adjust the planned work based on results.
正解：D
解説：
To determine the best description of the team's performance, we analyze the chart showing:
Committed work (orange bars): what the team planned to do.
Actual work completed (blue bars): what the team actually accomplished.
Key Observations:
In most sprints (e.g., 1, 3, 4, 5, 6, 8, 10), the actual work is slightly less than the committed work.
In Sprints 9 and 10, the actual work exceeds the committed work.
There's inconsistency in how much work is completed compared to what's committed.
Interpretation:
The team frequently overestimates its capacity. This suggests a misalignment between planning and execution, which indicates that their velocity is not yet well-understood or accurately reflected in sprint planning.
According to the CompTIA Project+ PK0-005 Exam Objectives:
Under Domain 1.2: Compare and contrast Agile vs. Waterfall concepts, understanding team velocity, iteration planning, and the ability to plan based on past performance is key to Agile success.
"Agile teams should use velocity as a guide to improve predictability. Sprint commitments should align with the team's proven delivery capacity."
質問 # 263
Which of the following can a project manager infer from the following velocity chart?
- A. The project is at risk.
- B. The project is on schedule.
- C. The project is behind schedule.
- D. The project Is ahead of schedule.
正解：C
解説：
The velocity chart typically shows the amount of work completed over time. If the "Actual Effort" line is below the "Planned Timeline," it indicates that the project is not progressing as fast as planned, hence it is behind schedule. This is inferred by comparing the actual work completed against what was scheduled.
References = The answer is based on standard project management practices and the typical interpretation of velocity charts in project management. For detailed information, please refer to the CompTIA Project+ Study Guide and other official CompTIA resources.
質問 # 264
Given the following velocity chart:
Which of the following updates on the project status should the Scrum master provide to the senior management team?
- A. The project has scope creep.
- B. The project utilized all of its available reserve.
- C. The project is trending ahead of schedule.
- D. The project deviated from the critical path.
正解：C
解説：
A velocity chart is a tool used in agile project management to track the progress and performance of a project team over time. It shows the number of features or user stories completed in each iteration or sprint. The planned timeline line represents the expected or ideal velocity, while the actual effort line shows the actual or achieved velocity. By comparing the two lines, the Scrum master can identify any gaps, trends, or issues in the project delivery.
Based on the image, the most likely update that the Scrum master can provide to the senior management team is D.
The project is trending ahead of schedule. This is because the actual effort line is above the planned timeline line for most of the time, indicating that the project team is completing more features than expected in each sprint. This means that the project is ahead of schedule and has a positive velocity variance.
質問 # 265
Which of the following activities are performed during the closing phase? (Select three).
- A. Working with the financial team to obtain return of investment
- B. Informing the functional manager about the release of resources
- C. Recognizing project team efforts and rewarding team members
- D. Updating the risk register with new findings
- E. Revoking resource credentials from the system
- F. Monitoring project team performance
- G. Requesting project charter sign-off
正解：B、C、E
解説：
The closing phase of a project involves finalizing all project activities, delivering the project deliverables,
releasing the project resources, and closing out the project accounts. Some of the activities that are performed
during this phase are12:
*Recognizing project team efforts and rewarding team members. This is an important activity to acknowledge
the contributions of the project team, celebrate the project success, and motivate the team members for future
projects. Recognition and rewards can be given in various forms, such as certificates, bonuses, gifts, or
feedback.
*Revoking resource credentials from the system. This is a security measure to ensure that the project resources,
such as staff, contractors, vendors, or consultants, do not have access to the project systems, data, or assets
after the project is completed. Revoking credentials can prevent unauthorized access, data breaches, or misuse
of project resources.
*Informing the functional manager about the release of resources. This is a communication activity to notify
the functional manager, who is responsible for the allocation and management of resources, that the project
resources are no longer needed and can be reassigned to other projects or tasks. Informing the functional
manager can help to optimize the resource utilization, avoid resource conflicts, and plan for future resource
needs.

質問 # 266
Which of the following factors would be impacted the most by requirements for a project to implement an air quality control system at a coal plant?
- A. Social
- B. Governmental
- C. Regulatory
- D. Environmental
正解：D
解説：
The environmental factor would be impacted the most by requirements for a project to implement an air quality control system at a coal plant. This is because coal combustion produces various air pollutants, such as particulate matter (PM), sulfur dioxide (SO2), nitrogen oxides (NOx), carbon dioxide (CO2), and mercury, that can harm human health and the environment12. An air quality control system can reduce the emissions of these pollutants by using different technologies, such as low NOx burners, flue gas desulfurization, electrostatic precipitators, and carbon capture and storage23. However, these technologies also have environmental impacts, such as water consumption, waste generation, energy consumption, and greenhouse gas emissions4. Therefore, the project manager should consider the environmental factor in terms of the project scope, objectives, constraints, risks, and stakeholders, and evaluate the trade-offs and benefits of different air quality control options5. References = CompTIA Project+ Study Guide: Exam PK0-005, 3rd Edition, Chapter 3: Project Scope Management, p. 97; Update on air pollution control strategies for coal-fired power plants; AQCS Air Quality Control Systems; NOx control for high-ash coal-fired power plants in India; Coal Dust Control

質問 # 269
A project manager has been informed that the delivery of required IT equipment will be delayed. Which of the
following is the FIRST step the project manager should take?
- A. Make an impact assessment.
- B. Select a new vendor.
- C. Create a risk register.
- D. Prepare a new purchase order.
正解：A
解説：
The project manager should make an impact assessment after being informed that the delivery of required IT
equipment will be delayed. An impact assessment is a process of analyzing and evaluating how a change or an
issue may affect the scope, schedule, cost, quality, or risks of a project. An impact assessment can help to
determine the severity and implications of the delay on the project objectives and deliverables and identify any
possible alternatives or corrective actions to minimize or avoid its negative effects.
質問 # 270
A company that is implementing an updated version of its main product hired a new project manager to lead the project. Prior to the start of the project, the sponsor asked the project manager to prepare a report on the defects found in the previous project to avoid a decrease in production. The report shows that the two main defects are related to cosmetic and physical damage to the product. Which of the following charts would BEST prioritize which defects to address?
- A. Control
- B. Pareto
- C. Histogram
- D. Run
正解：B
解説：
The project manager should use a Pareto chart to prioritize which defects to address for the product. A Pareto chart is a type of bar chart that shows the frequency or impact of different causes of problems or defects. It also shows a cumulative line that represents the percentage of the total frequency or impact. A Pareto chart can help to prioritize the causes that have the most significant effect on the quality of the product and apply the
80/20 rule, which states that 80% of the problems are caused by 20% of the causes.
質問 # 271
Which of the following is the best example of a breach of physical security?
- A. Developers having full access to both development and production environments
- B. Printers that do not request user authentication
- C. System user IDs being used by multiple individuals
- D. Project documentation that is only kept on a removable device
正解：D
解説：
A breach of physical security is an unauthorized access or damage to physical assets, such as equipment, data, or personnel. Project documentation that is only kept on a removable device is the best example of a breach of physical security, because it exposes sensitive information to theft, loss, or corruption. If the removable device is not encrypted or protected, anyone who obtains it can access the project documentation and compromise the project integrity, confidentiality, or availability. Therefore, project documentation should be stored in a secure location, backed up regularly, and protected by access controls and encryption.
The other options are not examples of physical security breaches, but rather logical or administrative security breaches. System user IDs being used by multiple individuals is a violation of the principle of least privilege and accountability, which could lead to unauthorized access or misuse of system resources. Printers that do not request user authentication is a lack of proper access control, which could allow unauthorized printing or retrieval of confidential documents. Developers having full access to both development and production environments is a violation of the principle of separation of duties and environments, which could introduce errors, conflicts, or malicious code into the production system.

質問 # 272
Which of the following best explains why companies apply background screening during the employment process?
- A. To evaluate PHI
- B. To apply operational security
- C. To define KPIs for new employees
- D. To increase access restrictions
正解：B
解説：
Background screening is an operational security control: it helps organizations reduce the risk of insider threats, fraud, and inappropriate access by verifying identity, employment history, and other relevant checks before granting trust, credentials, and system access. This aligns with security governance practices that protect organizational assets (data, systems, finances, customers) by ensuring personnel are vetted according to policy and role sensitivity.
Option A ("increase access restrictions") is related but incomplete-screening doesn't restrict access by itself; it supports decisions about whether access should be granted at all, and at what level. Option B (define KPIs) is performance management, not security. Option C (evaluate PHI) is healthcare-data specific and not the purpose of background checks.
In project environments, especially those handling sensitive data (PII/financial/customer records) or regulated work, background screening supports compliance and reduces risk exposure. It's part of broader operational security controls alongside least privilege, need-to-know, MFA, monitoring, and offboarding. Therefore, the best explanation is to apply operational security.
質問 # 273
A project manager is beginning a new project that will include a high number of complex deliverables. Which of the following is the best to use to track deliverables that are yet to be completed?
- A. Ticketing system
- B. Resource management system
- C. Issue log
- D. Backlog
正解：D
解説：
A backlog is commonly used in agile project management to list deliverables and tasks that have not yet been completed. It allows the project manager to prioritize and organize the workload, especially for complex projects. This aligns with agile principles as outlined in CompTIA Project+.
質問 # 274
A PM is working on the preliminary scope statement and identifies that this project has the same approach as another project that was completed last year. Which of the following actions would the PM most likely perform?
- A. Use existing artifacts and accommodate based on the current project success criteria.
- B. Ask the project sponsor to provide previous final project report results.
- C. Call the previous PM for advice on risks and issues.
- D. Complete the project charter using the other PM's subject matter expertise.
正解：A
解説：
This answer is based on the best practice of using historical information and lessons learned from previous projects to improve the planning and execution of current projects12. By using existing artifacts, such as scope statements, project plans, risk registers, and change logs, the PM can leverage the knowledge and experience of the previous PM and avoid repeating the same mistakes or oversights. However, the PM should also accommodate the artifacts based on the current project success criteria, which may differ from the previous project in terms of scope, schedule, budget, quality, or stakeholder expectations34. The PM should not rely solely on the previous PM's advice, the project sponsor's report, or the project charter, as these sources may not provide enough detail or accuracy for the current project's scope statement.

質問 # 276
Which of the following tools is best to use when conducting project meetings across time zones?
- A. Email
- B. Text
- C. Videoconference
- D. Calendaring tools
正解：C
解説：
Videoconference is the best tool to use when conducting project meetings across time zones, as it allows real-time communication, visual cues, screen sharing, and collaboration among the participants. Videoconference can also help build rapport and trust among the team members, and reduce the risk of misunderstandings or miscommunication. Videoconference tools such as Zoom, Skype, or Google Meet can also accommodate different time zones by showing the local time of each participant and allowing them to schedule meetings in advance12.
質問 # 277
A PM is working on the schedule for a project that has technical tasks and requires a SME's knowledge. The
PM decides the best way to track this project is to have the project lead provide high-level updates. Which of
the following is the best tool to track this data?
- A. Gantt chart
- B. Milestone chart
- C. Project organization chart
- D. Program Evaluation Review Technique chart
正解：B
解説：
A milestone chart is a tool that shows the key events or deliverables of a project along a timeline12. A
milestone chart is useful for tracking the progress of a project that has technical tasks and requires a SME's
knowledge, because it can provide a high-level overview of the project status, without getting into the details
of each task or activity34. A milestone chart can help the PM and the project lead communicate the project
achievements, challenges, and expectations to the stakeholders, and also identify any potential risks or delays
that may affect the project completion56. A milestone chart is better than the other options because:
A Gantt chart is a tool that shows the tasks, dependencies, durations, and resources of a project along a
timeline7. A Gantt chart is more detailed and complex than a milestone chart, and may not be suitable
for providing high-level updates to the stakeholders8.
A project organization chart is a tool that shows the roles, responsibilities, and reporting relationships of
the project team members and other stakeholders9. A project organization chart is not a tool for tracking
project data, but rather for defining the project structure and authority10.
A Program Evaluation Review Technique (PERT) chart is a tool that shows the tasks, dependencies, and
critical path of a project along a network diagram. A PERT chart is more focused on the sequence and
timing of the project tasks, and may not capture the key milestones or deliverables of the project.
