質問 # 67
What are three ways Scrum promotes self-organization? (Choose three.)
- A. By being a lightweight framework.
- B. By removing titles for Development Team members.
- C. By the Development Team deciding what work to do in a Sprint.
- D. By not allowing documentation.
- E. By preventing stakeholders from entering the development room.
正解：A、B、C
解説：
According to the Scrum Guide1, Scrum promotes self-organization by giving autonomy and empowerment to the Developers who decide how to do their work within a Sprint. The Developers have no titles other than Developer, regardless of their specialization or skills. Scrum is a lightweight framework that minimizes prescription and maximizes flexibility and adaptability.
質問 # 68
How much of the Sprint Backlog must be defined during the Sprint Planning event?
- A. Just enough to understand design and architectural implications.
- B. Just enough tasks for the Scrum Master to be confident in the Development Team's understanding of the Sprint.
- C. The entire Sprint Backlog must be identified and estimated by the end of the Sprint Planning meeting.
- D. Enough so the Development Team can create its best forecast of what is can do, and to start the first several days of the Sprint.
正解：D
解説：
The correct answer is C, because the Scrum Guide states that "the Development Team usually starts by designing the system and the work needed to convert the Product Backlog into a working product Increment. Work planned for the first days of the Sprint by the Development Team is decomposed by the end of this meeting, often to units of one day or less. The Development Team self-organizes to undertake the work in the Sprint Backlog, both during Sprint Planning and as needed throughout the Sprint." Therefore, enough work should be defined during the Sprint Planning event so that the Development Team can create its best forecast of what it can do, and to start the first several days of the Sprint.
質問 # 69
Which of the following best describes an increment of working software? (Choose the best answer.)
- A. A decomposition of all Product Backlog items into tasks for future Sprint Backlog lists.
- B. Additional features in a usable state that complement those delivered in previous iterations.
- C. UML diagrams that describe how to deliver functionality in future iterations.
- D. An automated test suite to verify functionality delivered in previous iterations.
- E. A new user interface design for functionality delivered in previous iterations.
正解：B
質問 # 70
When does the second Sprint start?
- A. Once the architectural changes for the second Sprint have been approved by the senior architect.
- B. Immediately after the first Sprint.
- C. After the customer completes acceptance testing of the first Sprint.
- D. After the Product Backlog for the second Sprint has been selected.
正解：B
解説：
The correct answer is C, because the second Sprint starts immediately after the first Sprint. The Scrum Guide states that "Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous Sprint."
質問 # 71
Why is the Daily Scrum held at the same time and same place?
- A. Rooms are hard to book and this lets it be booked in advance.
- B. The consistency reduces complexity.
- C. The place can be named.
- D. The Product Owner demands it.
正解：B
解説：
According to the Scrum Guide, the Daily Scrum is held at the same time and same place to reduce complexity and promote consistency. The other options are not valid reasons for holding the Daily Scrum at the same time and same place, as they are either irrelevant (such as naming the place) or incorrect (such as being demanded by the Product Owner or booking rooms in advance).
質問 # 72
What does it mean to say that an event has a time-box?
- A. The event must take at least a minimum amount of time.
- B. The event must happen by a given time.
- C. The event must happen at a set time.
- D. The event can take no more than a maximum amount of time.
正解：D
解説：
According to the Scrum Guide1, each event in Scrum is a formal opportunity to inspect and adapt something. These events are specifically designed to enable critical transparency and inspection. Failure to include any of these events results in reduced transparency and is a lost opportunity to inspect and adapt. All events are time-boxed events, such that every event has a maximum duration. Once a Sprint begins, its duration is fixed and cannot be shortened or lengthened. The remaining events may end whenever the purpose of the event is achieved, ensuring an appropriate amount of time is spent without allowing waste in the process.
質問 # 73
During the Sprint Retrospective a Scrum Team has identified several high priority process improvements.
Which of the following statements is most accurate? (Choose the best answer.)
- A. The Scrum Team should decline to add a process improvement to the Sprint Backlog when things are running smoothly.
- B. The Scrum Team may add items to the Sprint Backlog for the next Sprint.
- C. The Scrum Team should choose at least one high priority process improvement to place in the Product Backlog.
- D. The Scrum Master selects the most important process improvement and places it in the Sprint Backlog
正解：B
質問 # 74
The Sprint Goal is a result of Sprint Planning, as is the Sprint Backlog.
- A. True
- B. False
正解：A
解説：
According to the Scrum Guide1, the Sprint Goal is an objective set for the Sprint that can be met through the implementation of Product Backlog. It provides guidance to the Developers on why it is building the Increment. It also provides a basis for inspecting and adapting during the Sprint Review and Sprint Retrospective. The Sprint Goal is a result of Sprint Planning, as is the Sprint Backlog.
質問 # 75
To get started in terms of what to build, Scrum requires no more than a Product Owner with enough ideas for a first Sprint, a Development Team to implement those ideas and a Scrum Master to help guide the process.
- A. True
- B. False
正解：A
質問 # 76
How should a Development Team deal with non-functional requirements?
- A. Handle them during the Integration Sprint preceding the Release Sprint.
- B. Ensure every Increment meets them.
- C. Assign them to the lead developers on the team.
- D. Makesure the release department understands these requirements, but it is not the Development Team's responsibility.
正解：B

正解：B、D
質問 # 81
A Scrum Master is working with a Development Team that has members in different physical locations. The Development Team meets in a variety of meeting rooms and has much to do logistically (for example, set up conference calls) before the Daily Scrum. What action should the Scrum Master take? (Choose the best answer.)
- A. Set up the meeting and tell the Development Team that is how it will be done.
- B. Ask the Development Team members to alternate who is responsible for meeting setup.
- C. Inform management and ask them to solve it.
- D. Allow the Development Team to self-manage and determine for itself what to do.
正解：D
質問 # 82
The Development Team should have all the skills needed to:
- A. Complete the project within the date and cost as calculated by the Product Owner.
- B. Do all of the development work, except for specialized testing that requires additional tools and environments.
- C. Turn Product Backlog items into an Increment of potentially releasable product functionality.
正解：C
解説：
According to the Scrum Guide1, an Increment is a concrete stepping stone toward the Product Goal. Each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together. In order to provide value, an Increment must be usable. Multiple Increments may be created within a Sprint. The sum of the Increments is presented at the Sprint Review thus supporting empiricism. However, an Increment may be delivered to stakeholders prior to the end of the Sprint. The Sprint Review should never be considered a gate to releasing value. Therefore, in order to turn Product Backlog items into an Increment of potentially releasable product functionality, the Development Team should have all the skills needed.
質問 # 83
Which two things should the Development Team do during the first Sprint? (Choose two.)
- A. Analyze, describe, and document the requirements for the subsequent Sprints.
- B. Create an increment of potentially releasable software.
- C. Analyze, design, and describe the complete architecture and infrastructure.
- D. Develop at least one piece of functionality.
- E. Make up a plan for the rest of the project.
正解：B、D
解説：
According to the Scrum Guide1, each Sprint is a project with no more than a one-month horizon. The Sprint Goal gives guidance to why the Scrum Team is building an Increment. The Development Team consists of professionals who do the work of delivering a potentially releasable Increment of "Done" product at the end of each Sprint. Therefore, in the first Sprint, as in any other Sprint, the Development Team should develop at least one piece of functionality and create an increment of potentially releasable software. The other options are not consistent with Scrum values and principles.
