質問 # 16
A new developer is having continuing conflicts with existing Development Team members and creating the hostile environment. If necessary, who is responsible for removing the team member?
- A. The hiring manager is responsible, because he/she hired the developer.
- B. The Product Owner is responsible, because he/she controls the return on investment (ROI).
- C. The Scrum Manager is responsible, because he/she removes Impediments.
- D. The Development Team is responsible, and may need help from the Scrum Master.
正解：D
解説：
The correct answer is C, because if necessary, the Development Team is responsible for removing a team member who is creating a hostile environment. The Scrum Guide states that "development Teams are self-organizing. No one (not even the Scrum Master) tells the Development Team how to turn Product Backlog into Increments of potentially releasable functionality." Therefore, the Development Team should manage its own composition and dynamics, and may need help from the Scrum Master to facilitate this process.
質問 # 17
Which statement best describes the Sprint Backlog as outcome of the Sprint Planning?
- A. Every item has a designated owner.
- B. It is ordered by the Product Owner.
- C. It is the Development Team's plan for the Sprint.
- D. It is a complete list of all work to be done in a Sprint.
- E. Each task is estimated in hours.
正解：C
解説：
The Sprint Backlog is the Development Team's plan for the Sprint, as stated in the Scrum Guide1: "The Sprint Backlog is a plan with enough detail that changes in progress can be understood in the Daily Scrum. The Development Team modifies the Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint."
質問 # 18
When many Development Teams are working on a single product, what best describes the definition of "Done"? (Choose the best answer.)
- A. It depends.
- B. Each Development Team uses its own but must make their definition clear to all other teams so the differences are known.
- C. Each Development Team defines and uses its own. The differences are discussed and reconciled during a hardening Sprint.
- D. All Development Teams must have a definition of "Done" that makes their combined work potentially releasable.
正解：D
質問 # 19
The Product Owner determines how many Product Backlog items the Development Team selects for a Sprint. (Choose the best answer.)
- A. True, but only after confirmation by the resource manager that the Team has enough capacity.
- B. False, the Scrum Master does that.
- C. True, accordingly to what was committed to the stakeholders.
- D. False.
- E. True.
- F. False, capacity and commitment are the Project manager's responsibility.
正解：D

質問 # 21
When must the Product Owner participate in the Dairy Scrum? (choose the best answer)
- A. When the Scrum Master asks the Product Owner to attend
- B. When there are impediments to discuss
- C. When the Product Owner needs to represent the stakeholders point of view to the Developers
- D. When the Product Owner is actively working on items on the Sprint Backlog; however, they participate as a Developer
正解：D
解説：
According to the Scrum Guide, the Product Owner must participate in the Daily Scrum when he or she is actively working on items on the Sprint Backlog; however, they participate as a Developer, not as an authority figure. This means that the Product Owner can share progress, plans, and impediments with the other Developers and collaborate with them on delivering value. The other options are not valid reasons for the Product Owner to participate in the Daily Scrum, as they are either irrelevant (such as representing stakeholders or discussing impediments) or inappropriate (such as being asked by the Scrum Master).
質問 # 22
A Development Team asks their Product Owner to re-order the Product Backlog. The team is waiting for an external supplier to deliver a specific software component.Without that component there won't be enough work in the next Sprint to occupy the full team. The Product Owner asks the Scrum Master for help. What would be good advice to give the Product Owner?
- A. Tell the Product Owner that the Product Backlog should be ordered to maximize utilization of the Development Team.
- B. Tell the Product Owner to re-order the Product Backlog so the work involving the external component can be planned in a separate sprint.
- C. Tell the Product Owner that his primary concern isthe flow of value reflected in the ordering of the Product Backlog.
正解：C
質問 # 23

- A. If the stakeholders agree, the Product Owner can accept it and release it to the users.
- B. Put it on the Product Backlog for the Product Owner to decide what to do with it.
- C. Do not include the item in the Increment this Sprint.
- D. Review the item, add the "Done" part of the estimate to the velocity and create a Story for the remaining work.
正解：B、C
質問 # 25
You have just been hired by a company new to Scrum. Your management has assigned you to be the Scrum Master of six new Scrum Teams. These teams will build one product. Select two conditions you should strive for in this scenario. (Choose two.)
- A. There should be six Product Owners, reporting to a chief Product Owner.
- B. There should be only one Product Owner.
- C. The product has one Product Backlog.
- D. There should be six Product Owners, one for each Scrum Team.
- E. Each Scrum Team should have a separate Product Backlog.
正解：B、C
解説：
The product has one Product Backlog, as it is a single source of requirements for any changes to be made to the product. There should be only one Product Owner, who is accountable for maximizing the value of the product and the work of the Development Team. Having multiple Product Owners or Product Backlogs would create confusion, inconsistency, and waste.

質問 # 27
Which three behaviors demonstrate that a team is self-organizing? (Choose three.)
- A. Development Team members collaboratively selecting their own work during the Sprint.
- B. The Product Owner doesn't need to be at Sprint Retrospectives.
- C. The Development Team members are working within the boundaries of their functional description and nicely handing off work from analyst to developer to tester to integration.
- D. The Development Team inviting external people to the Sprint Planning to ask them how to turn a Product Backlog item into an Increment via a complete and detailed Sprint Backlog.
- E. The Scrum Master is no longer needed.
- F. The Development Team has all the skills needed to create a releasable Increment.
- G. Stakeholders walking in at the Daily Scrum to check progress and work with the Scrum Master to optimize the functional scope for the Sprint.
- H. The Development Team creating their own sprint backlog, reflecting all work that is part of the definition of "Done".
正解：A、F、H
解説：
According to the Scrum Guide, three behaviors that demonstrate that a team is self-organizing are creating their own sprint backlog, having all the skills needed to create a releasable Increment, and collaboratively selecting their own work during the Sprint. The other options are not behaviors that demonstrate self-organization, as they are either contrary to Scrum values and principles (such as stakeholders walking in at the Daily Scrum or working within functional boundaries) or unnecessary for self-organization (such as the Product Owner not being at Sprint Retrospectives or the Development Team inviting external people to the Sprint Planning).
質問 # 28
Where are two good ways for the Development Team to make non-functional requirements visible? (Choose two.)
- A. Run the integration and regression tests before the end of the Sprint, and capture the open work for the Sprint Backlog of the next Sprint.
- B. Put them on aseparate list on the Scrum board, available for all to see.
- C. Add them to the Product Backlog and keep the Product Owner posted on the expected effort.
- D. Add them to the definition of "Done" so the work is taken care of every Sprint.
- E. Run the integration and regression tests before the end of the Sprint, and capture the open work forthe Sprint Backlog of the next Sprint.
正解：C、D
質問 # 29
When many Scrum Teams are working on a single product, what best describes the Definition of Done?
(Choose the best answer.)
- A. Each Scrum Team uses its own, but must make their definition clear to all other teams so the differences are known.
- B. Each Scrum Team defines and uses its own. The differences are discussed and reconciled during a hardening Sprint.
- C. All Scrum Teams must have a Definition of Done that makes their combined work potentially releasable.
- D. The Scrum Masters from each Scrum Team define a common Definition of Done.
正解：C
解説：
According to the Scrum Guide, when many Scrum Teams are working on a single product, they must have a Definition of Done that makes their combined work potentially releasable. This ensures that there is a clear and consistent understanding of what "Done" means for the product and that there is no technical debt or unfinished work at the end of each Sprint. The other options are not valid descriptions of the Definition of Done for multiple Scrum Teams, as they either create inconsistency, confusion, or waste (such as having different definitions, discussing and reconciling differences during a hardening Sprint, or having the Scrum Masters define a common Definition of Done).
質問 # 30
What are two ways that regulatory compliance issues are dealt with in Scrum?
(choose the best two answers)
- A. They are discussed, determined, and documented before the actual feature development Sprints.
- B. They are addressed by a separate team who is responsible for compliance issues.
- C. They are addressed along with functional development of the product.
- D. They are added to the Product Backlog and addressed in early Sprints, while always requiring at least some business functionality, no matter how small.
正解：C、D
解説：
The best two answers are B and D. These two ways of dealing with regulatory compliance issues are consistent with Scrum's values and principles, as they allow the Scrum Team to deliver valuable and potentially releasable increments of the product while meeting the necessary standards and regulations. They also enable the Scrum Team to inspect and adapt their compliance strategy based on feedback and changing requirements.
A is not a good answer because it creates a separate silo of responsibility for compliance issues, which can lead to delays, conflicts, and inefficiencies. It also violates the Scrum value of transparency, as the compliance team may not have full visibility into the product development process.
C is not a good answer because it implies a waterfall approach that assumes all the compliance requirements are known and fixed upfront, which is rarely the case. It also reduces the flexibility and responsiveness of the Scrum Team, as they may have to follow a rigid plan that does not reflect the current reality of the product or the market.
質問 # 31
What are two responsibilities of testers in a Development Team? (Choose two.)
- A. Verifying the work of programmers.
- B. Everyone in the Development Team is responsible for quality.
- C. Scrum has no "tester" role.
- D. Finding bugs.
- E. Tracking quality metrics.
正解：B、C
解説：
Explanation
質問 # 32
A Scrum Team is only allowed to meet with stakeholders during Sprint Review.
- A. False
- B. True
正解：A
解説：
According to the Scrum Guide, a Scrum Team is not only allowed to meet with stakeholders during Sprint Review, but also during Sprint Planning and throughout the Sprint as needed. The Sprint Review is an opportunity for the Scrum Team and the stakeholders to collaborate on what was done in the Sprint and what to do next. However, it is not the only time that stakeholder feedback is welcomed and valued.
質問 # 33

- A. False
- B. True
正解：A
解説：
A Scrum Master fulfills a different role than a traditional project manager, as stated in 2: "A project manager helps manage the project timeline, resources, and scope in order to meet business requirements. A Scrum Master, however, helps ensure the Scrum Team follows Scrum theory, practices, and rules. The Scrum Master is a servant-leader who helps optimize the value created by the Scrum Team."
質問 # 35
What it the main reason for the Scrum Master to be at the Daily Scrum?
- A. To write down any changes to the Sprint Backlog,including adding new items, and tracking progress on the burn-down.
- B. To gather status and progress information to report to management.
- C. To make sure every team member answers the three questions.
- D. He or she does not have to be there; he or she only has to ensure the Development Team has a Daily Scrum.

質問 # 36
When is the Sprint Backlog created?
- A. Prior to the Sprint Planning meeting.
- B. During the Sprint.
- C. At the beginning of the project.
- D. During the Sprint Planning meeting.
正解：D
解説：
The correct answer is B, because the Sprint Backlog is created during the Sprint Planning meeting. The Scrum Guide states that "the Sprint Backlog is the set of Product Backlog items selected for the Sprint, plus a plan for delivering the product Increment and realizing the Sprint Goal."
