質問 # 84
When is implementation of a Product Backlog item considered complete? (Choose the best answer)

A. When the item has no work remaining in order to be potentially released.
B. When all work in the Sprint Backlog related to the item is finished.
C. At the end of the Sprint.
D. When QA reports that the item passes all acceptance criteria.

正解：A

質問 # 85
Who should make sure everyone on the Development Team does their tasks for the Sprint?

A. The Project Manager.
B. The Development Team.
C. All of the above.
D. The Product Owner.
E. The Scrum Master.

正解：B

解説：
According to the Scrum Guide1, the Developers are self-organizing and decide how to turn Product Backlog items into an Increment of value. No one tells them how to do their work. The Developers are accountable for creating a plan for the Sprint, the Sprint Backlog. The other roles are not responsible for making sure everyone on the Development Team does their tasks for the Sprint.

質問 # 86
Which technique is the best way the Scrum Master can ensure that the Development Team communicates
effectively with the Product Owner?

A. Act as a go-between for them.
B. Teach the Development Team to talk in terms of business needs and objectives.
C. Monitor communications between them and facilitate direct collaboration.
D. Teach the Product Owner about the technologies employed during the Sprints.

正解：C

質問 # 87
Marian is the Product Owner envisioning a project for a new release of her product. She made a projection of a release date based upon a sustained velocity of 17 completed units of work per Sprint. Over the first 3 Sprints, the average velocity was 13 for work that the Development Team estimated as 90% done. The Development Teams, feeling the need to meet the plan, figured that a velocity of 17 was within their reach.
A good way to continue is:

A. The Development Team should remind Marian to find funding for enough Release Sprints in which the remaining work can be done.
B. The opportunity to inspect and adapt is lost. Opaqueness has replaced transparency. Predictability has dropped below zero. The produced software is not usable. As the rules of Scrum have not been respected, it is the Scrum Master's duty to assess whether repair is possible, or a restart with a more reliable team. If not, the Scrum Master should cancel the project.
C. The Development Team makes sure that all of the selected scope per Sprint is as "Done" as possible. The undone work is estimated and added to the Sprint Backlog of the next Sprint, so it doesn't mess up the Product Backlog.
D. Add enough people to the Development Team for the deadline to be made.

正解：C

解説：
According to the Scrum Guide1, each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together. In order to provide value, the 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, a good way to continue is for the Development Team to make sure that all of the selected scope per Sprint is as "Done" as possible. The undone work is estimated and added to the Sprint Backlog of the next Sprint, so it doesn't mess up the Product Backlog.

質問 # 88
Which two things should the Scrum Team do during the first Sprint?
(choose the best two answers)

A. Analyze, describe, and document the requirements for the subsequent Sprints.
B. Define the major product features and a release plan architecture.
C. Make up a plan tor the rest of the project
D. Build at least one piece of valuable functionality.
E. Create at least one valuable, useful Increment

正解：D、E

解説：
According to the Scrum Guide, two things that the Scrum Team should do during the first Sprint are building at least one piece of valuable functionality and creating at least one valuable, useful Increment. These are the goals of every Sprint, regardless of its order. The other options are not things that the Scrum Team should do during the first Sprint, as they are either out of scope (such as defining major product features and a release plan architecture or making a plan for the rest of the project) or unnecessary (such as analyzing, describing, and documenting requirements for subsequent Sprints).

質問 # 89
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

解説：
According to the Scrum Guide1, Scrum does not require or provide any specific techniques or methods for product definition. Rather, Scrum provides a framework with roles, rules, and events within which complex products can be developed. 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.

質問 # 90
Which of the following are true about the Product Owner role? (Choose two.)

A. Multiple people can share the Product Owner role on a Scrum Team.
B. The Product Owner is accountable for ordering the Product Backlog.
C. The Product Owner role can be played by a committee or a team of people.
D. The Product Owner is one person.

正解：B、D

解説：
The correct answers are A and B, because these are true about the Product Owner role. The Product Owner is one person, not a committee or a team, who is accountable for ordering the Product Backlog and maximizing the value of the product. The Scrum Guide states that "the Product Owner is responsible for maximizing the value of the product resulting from work of the Development Team. How this is done may vary widely across organizations, Scrum Teams, and individuals. ... For the Product Owner to succeed, the entire organization must respect his or her decisions."

質問 # 91
Why does the Product Owner want the Development Team to adhere to its definition of "Done"?

A. To know what the team will deliver over the next three Sprints.
B. To have complete transparency into what has been done at the end of each Sprint.
C. To predict the team's productivity over time.
D. To be able to reprimand the team when they don't meet their velocity goal for the Sprint.

正解：B

解説：
According to the Scrum Guide1, the definition of "Done" is a formal description of the state of the Increment when it meets the quality measures required for the product. The definition guides the Development Team in creating a "Done" Increment. The definition of "Done" is created by the development organization (or Development Team if none is available from the development organization). The definition of "Done" may vary significantly per Scrum Team, depending on the context. One aspect of Scrum Teams inspecting how they work toward their Product Goal is that they improve their definition of "Done" over time. Therefore, one reason why the Product Owner wants the Development Team to adhere to its definition of "Done" is to have complete transparency into what has been done at the end of each Sprint.

質問 # 92
The Sprint Review is mainly an inspect and adapt opportunity for which group?

A. The Scrum Team and stakeholders.
B. The Product Owner and Development Team.
C. The Product Owner and management.
D. The Development Team and management.
E. The Product Owner and stakeholders.
F. The Development Team and stakeholders.

正解：A

解説：
According to the Scrum Guide1, the Sprint Review is an informal meeting at the end of the Sprint, where the Scrum Team and stakeholders collaborate about what was done in the Sprint. Based on that and any changes to the Product Backlog during the Sprint, attendees collaborate on what to do next. The Product Owner explains what Product Backlog items have been "Done" and what has not been "Done"; the Development Team discusses what went well during the Sprint, what problems it ran into, and how those problems were solved; and the Development Team demonstrates the work that it has "Done" and answers questions about the Increment. The entire group collaborates on what to do next, so that the Sprint Review provides valuable input to subsequent Sprint Planning. The Sprint Review is mainly an inspect and adapt opportunity for the Scrum Team and stakeholders.

質問 # 93
The Product Backlog is ordered by:

A. The Product Owner with the most valuable items placed at the top.
B. Size, where small items ale at the top and large items are at the bottom.
C. Items are randomly arranged.
D. Risk, where safer items are at the top, and riskier items are at the bottom.

正解：A

質問 # 94
As the Development Team starts work during the Sprint, it realizes it has selected too much work to finish in the Sprint. What should it do?

A. Inform the Product Owner at the Sprint Review, but prior to the demonstration.
B. Reduce the definition of "Done" and get all of the Product Backlog items "Done" by the new definition.
C. Find another Scrum Team to give the excess work to.
D. As soon as possible in the Sprint, work with the Product Owner to remove some work or Product Backlog items.

正解：D

解説：
The correct answer is C, because as soon as possible in the Sprint, the Development Team should work with the Product Owner to remove some work or Product Backlog items if they realize they have selected too much work to finish in the Sprint. The Scrum Guide states that "the Development Team may renegotiate the selected Product Backlog items with the Product Owner. If the Development Team realizes it has too much or too little work, it may renegotiate the selected Product Backlog items with the Product Owner. The Development Team may also invite other people to attend to provide technical or domain advice."

質問 # 95
What is the key concern when multiple Development Teams are working from the same Product Backlog?

A. Meeting original scope projections.
B. Minimizing dependencies between teams.
C. Maximizing velocity.
D. Clear definition of requirements.
E. Making sure there's enough work for everyone on every team.

正解：B

解説：
According to the Scrum Guide1, when multiple Scrum Teams are working together on one product, they must coordinate their work with each other. One way to do this is through Nexus, a framework for scaling Scrum. Nexus helps to reduce cross-team dependencies and integration issues by making them more transparent. The key concern when multiple Development Teams are working from the same Product Backlog is minimizing dependencies between teams so that they can deliver an integrated Increment that meets the definition of "Done".

質問 # 96
Which three of the following are time-boxed events in Scrum? (Choose three.)

A. Sprint 0.
B. Release Retrospective.
C. Sprint Planning.
D. Sprint Testing.
E. Sprint Retrospective.
F. Daily Scrum.
G. Release Testing.

正解：C、E、F

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. The time-boxed events in Scrum are:
Sprint Planning (eight hours or less for a one-month Sprint)
Daily Scrum (15 minutes or less for a one-month Sprint)
Sprint Review (four hours or less for a one-month Sprint)
Sprint Retrospective (three hours or less for a one-month Sprint)
The other options are not time-boxed events in Scrum.

質問 # 97
The IT manager asks a Development Team for a status report describing the progress throughout the Sprint.
The Development Team asks the Scrum Master for advice. The Scrum Master should:
(Choose the best answer.)

A. Tell the Development Team to fit the report into the Sprint Backlog.
B. Ask the Product Owner to send the manager the report.
C. Talk to the IT manager and explain that progress in Scrum comes from inspecting an Increment at the Sprint Review.
D. Create and deliver the report to the manager herself.
E. Tell the Development Team to figure it out themselves.

正解：C

質問 # 98
If burndown charts are used to visualize progress, what does a trend line through a release burndown chart indicate?

A. When all work will be completed to the Scrum Team can be released for other work.
B. When the work remaining will likely be completed if nothing changes on the Product Backlog or the Development Team.
C. The evolution of the cost spent on the project.
D. When the project will be over if the Product Owner removes work that is equal in effort to any new work that is added.

正解：B

解説：
a burndown chart is a graphical representation of work left to do versus time. It is very useful for predicting when all of the work will be completed. It is often used in agile software development methodologies such as Scrum. However, burndown charts can be applied to any project containing measurable progress over time. A release burndown chart tracks progress across multiple Sprints towards a product release. It shows how much work remains in the Product Backlog at any given time during the release cycle. A trend line through a release burndown chart indicates when the work remaining will likely be completed if nothing changes on the Product Backlog or the Development Team.
