質問 # 31
Which two (2) metrics will help a Product Owner establish that value is being delivered? (Choose the best two answers)

• A. Velocity.
• B. Productivity.
• C. Time to market.
• D. Budget spent.
• E. Customer satisfaction.

正解：C、E

解説：
The Product Owner's primary accountability is maximizing the value of the product, per theScrum Guide.
Metrics should reflect outcomes, not just internal process efficiency:
* A (Time to market):Faster delivery of Increments to the market validates value through real-world feedback, a key Scrum principle.
* B (Customer satisfaction):This directly measures whether the product meets user needs, aligning with value delivery.
* C (Velocity):While useful for Developers to gauge capacity, it's an internal metric, not adirect indicator of value.
* D (Productivity):This focuses on effort, not outcome, and isn't tied to value in Scrum.

質問 # 32
In order to make investment decisions, the Product Owner is likely to look at the Total Cost of Ownership (TCO) of the product being built. What costs will a Product Owner take into account? (Choose the best answer)

• A. The accumulated cost over the earned value of the product
• B. All investments required to conceive, develop, operate, and maintain the product
• C. The money spent on development of the product, often a fixed cost per Sprint multiplied by the Sprints required

正解：B

解説：
TCO encompasses all costs across a product's lifecycle, not just development. While theScrum Guidedoesn't define TCO, the Product Owner's value focus implies a broad view: "The Product Owner is accountable for maximizing the value of the product." Option B-conception, development, operation, and maintenance- reflects this holistic perspective.
* A:Development cost alone is too narrow.

質問 # 33
True or False: The Product Owner is an optional attendee of the Sprint Retrospective.

• A. False
• B. True

正解：A

解説：
The Sprint Retrospective is a mandatory event for the entire Scrum Team, including the Product Owner. The Scrum Guidespecifies: "The Sprint Retrospective is an opportunity for the Scrum Team to inspect itself and create a plan for improvements to be enacted during the next Sprint." As a Scrum Team member, the Product Owner's participation is essential for team-wide reflection and improvement.
* A:False-attendance isn't optional.

質問 # 34
Who must do all the work to make sure Product Backlog items conform to the Definition of "Done"? (Choose the best answer)

• A. QA Specialists
• B. The Developers
• C. The Scrum Master
• D. The Product Owner
• E. The Scrum Team

正解：B

解説：
TheScrum Guideclearly assigns the responsibility for delivering a "Done" Increment to the Developers: "The Developers are the people in the Scrum Team that are committed to creating any aspect of a usable Increment each Sprint." This includes all work-development, testing, integration, etc.-needed to meet the Definition of "Done," a shared commitment that ensures quality. Option A (Scrum Team) is too broad; while the Scrum Team collaborates, only the Developers perform the hands-on work. Option C (Product Owner) is incorrect- they manage the Product Backlog, not the execution. Option D (QA Specialists) introduces a role not defined in Scrum; quality is the Developers' collective responsibility. Option E (Scrum Master) is wrong-they facilitate, not build. Thus, B is correct.

質問 # 35
How can a Product Owner use time-boxed Sprints to obtain feedback from users and the market? (Choose the best answer)

• A. Through frequent delivery of Increments of the product into the market.
• B. A business analyst represents the Product Owner to make decisions on his behalf during the Sprint. This way the Product Owner can accept the work at the Sprint Review without further involvement.
• C. At the end of each Sprint, a detailed report with all test cases and test results is available.
• D. By making sure a Sprint does not stop until all testing is done, and the work is verified by the Product Owner.
• E. Through the assurance that a Developers finishes all work on the Sprint Backlog.

正解：A

解説：
Time-boxed Sprints in Scrum enable rapid feedback loops by delivering usable Incrementsregularly. The Scrum Guideemphasizes: "Sprints are the heartbeat of Scrum, where ideas are turned into value." Option B aligns with this-frequent releases to the market allow the Product Owner to gather real user and market feedback, validating assumptions and adjusting the Product Backlog.
* A:Finishing Sprint Backlog work is internal; it doesn't guarantee market feedback.
* C:Delaying Sprint end for testing contradicts the fixed time-box and "Done" requirement within the Sprint.
* D:Reports are informational, not direct market feedback.

質問 # 36
During which meeting do team members synchronize their work and progress and report any impediments to the Scrum Master for removal? (Choose the best answer)

• A. Daily Scrum
• B. Sprint Planning meeting
• C. Weekly status meeting
• D. Sprint Retrospective

正解：A

解説：
The Daily Scrum is designed for synchronization and impediment reporting. TheScrum Guidestates: "The purpose of the Daily Scrum is to inspect progress toward the Sprint Goal and adapt the Sprint Backlog as necessary, adjusting the upcoming planned work." Developers raise impediments, which the Scrum Master then addresses.
* A:Sprint Planning sets the Sprint's work, not daily sync.
* B:Correct-daily synchronization and impediment reporting.
* C:Retrospective focuses on improvement, not daily progress.

質問 # 37
What pre-conditions must be fulfilled in order to allow Sprint Planning to begin? (Choose the best answer)

• A. Formal budget approval to conduct another Sprint
• B. A clear but negotiable business objective for the Sprint
• C. A clear and non-negotiable Sprint Goal
• D. Enough "Ready" Product Backlog to fill the Sprint
• E. There are no such pre-conditions
• F. A fully refined Product Backlog

正解：E

解説：
Scrum imposes no formal pre-conditions for Sprint Planning beyond the Sprint starting. TheScrum Guide states: "Sprint Planning initiates the Sprint by laying out the work to be performed for the Sprint."
* A:A fully refined backlog isn't required; refinement is ongoing.
* B:Budget approval isn't a Scrum concept.
* C, D:The Sprint Goal is defined during, not before, Sprint Planning.
* E:Some "Ready" items help, but it's not mandatory; planning can refine items.

質問 # 38
When many Scrum Teams are working on the same product, should all of their Increments be integrated every Sprint? (Choose the best answer)

• A. No, that is far too hard and must be done in a hardening Sprint.
• B. No, each Scrum Team stands alone.
• C. Yes, otherwise the Product Owners and stakeholders may not be able to accurately inspect what is done.
• D. Yes, but only for Scrum Teams whose work has dependencies.

正解：C

解説：
TheScrum Guidemandates that when multiple Scrum Teams work on one product, they produce a single integrated Increment: "Multiple Scrum Teams often work together on the same product... The Increment must be integrated and usable so that it can provide value." This ensures transparency and stakeholder feedback at the Sprint Review. Option A (hardening Sprint) is a misconception-Scrum rejects separate phases for integration. Option B contradicts the single-product focus. Option C limits integration to dependencies, but the Scrum Guiderequires full integration regardless. Option D correctly emphasizes the need for a cohesive, inspectable Increment, making it the best answer.

質問 # 39
Who updates work remaining during the Sprint? (Choose the best answer)

• A. Product Owner
• B. Scrum Master
• C. Developers
• D. Senior Executives

正解：C

解説：
The Developers own the Sprint Backlog and update it as work progresses. TheScrum Guidestates: "The Sprint Backlog is a plan by and for the Developers... As new work is required, the Developers add it to the Sprint Backlog. As work is performed or completed, the estimated remaining work is updated."
* A:The Scrum Master facilitates, not updates.
* B:Correct-the Developers manage it.

質問 # 40
Why would the Product Owner concern themselves with technical debt? (Choose the best answer)

• A. They wouldn't, it is an issue for Developers
• B. The total cost of ownership (TCO) of the product will be impacted if technical debt is present and grows
• C. The Scrum Master is responsible for technical debt management

正解：B

解説：
Technical debt affects product value, a Product Owner's core concern. TheScrum Guidedoesn't explicitly mention technical debt, but the Product Owner's accountability for "maximizing the value of the product" implies considering factors like TCO, which rises with debt due to rework or maintenance costs.
* A:Correct-debt impacts long-term value and cost.
* B:The Scrum Master facilitates, not manages debt.

質問 # 41
True or False: There must be a release every Sprint.

• A. False
• B. True

正解：A

解説：
Scrum requires a "potentially releasable" Increment each Sprint, but actual release is at the Product Owner's discretion. TheScrum Guidestates: "The Increment must be usable... The Product Owner may choose to release it immediately."
* A:False-release isn't mandatory.

質問 # 42
Holding a Sprint 0 is the most effective way to: (Choose the best answer)

• A. There is no Sprint 0 in Scrum
• B. Define a reference architecture
• C. Create a complete Product Backlog
• D. Work on team development

正解：A

解説：
"Sprint 0" is a concept from pre-Scrum practices and isn't part of the official framework. TheScrum Guide mandates that Sprints deliver value: "A Sprint is a time-box of one month or less during which a 'Done', usable, and potentially releasable product Increment is created." A preparatory "Sprint 0" for architecture, team building, or backlog creation contradicts this by not producing an Increment.
* A, B, C:These may occur outside Sprints, but not as a "Sprint 0."

質問 # 43
The Product Owner is accountable for the functionality included in each Increment. Does he or she have the final say over the definition of "Done"?

• A. No, the Scrum Team is responsible for the definition of "Done". The Product Owner may be consulted.
• B. Yes, the Product Owner is responsible for the definition of "Done". The Developers may be consulted.

正解：A

解説：
TheScrum Guideclarifies that the definition of "Done" is a shared commitment created by the Scrum Team:
"The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product." While the Product Owner defines what goes into the Increment (via the Product Backlog), the definition of "Done" is a collaborative effort, often driven by the Developers' technical expertise and organizational standards, with input from the Product Owner on value and quality expectations.
Option A incorrectly gives the Product Owner sole authority, while B correctly reflects the team's collective responsibility, with the Product Owner as a contributor, not the final arbiter.

質問 # 44
Who assigns ownership of the Sprint Backlog items during the Sprint? (Choose the best answer)

• A. The Product Owner
• B. There is no single owner of a Product Backlog item, the entire team owns the Sprint Backlog
• C. Whoever has the skills
• D. Individual Team Members

正解：B

解説：
The Sprint Backlog is collectively owned by the Developers, not assigned to individuals. TheScrum Guide defines it as: "The Sprint Backlog is a plan by and for the Developers... It is a highly visible, real-time picture of the work that the Developers plan to accomplish during the Sprint." Self-organization means the Developers decide who does what, without fixed ownership of items.
* A, B:Individual assignment isn't mandated; it's a team effort.
* C:Correct-the Developers as a whole own it.

質問 # 45
True or False: A first Sprint can start before the Product Owner has a complete and exhaustive Product Backlog in place.

• A. False
• B. True

正解：B

解説：
Scrum doesn't require a fully detailed Product Backlog to begin. TheScrum Guidenotes: "The Product Backlog is an emergent, ordered list... It evolves over time." A minimal backlog with a Product Goal and some items is sufficient for the first Sprint, with refinement ongoing.
* A:True-Scrum embraces starting with what's known.

質問 # 46
True or False: Management does not have a role within Scrum.

• A. False
• B. True

正解：A

解説：
Management has a role in supporting Scrum, though not within the Scrum Team. TheScrum Guidenotes:
"Scrum Teams are cross-functional, meaning the members have all the skills necessary to create value each Sprint. They are also self-managing... Various practices exist to forecast progress, like burn-downs, burn-ups, or cumulative flows." Management provides resources, removes impediments, and sets organizational context, but doesn't manage the team directly.
* A:False-management supports externally.

質問 # 47
What three factors are best considered when establishing the Sprint length? (Choose the best three answers)

• A. The level of uncertainty over the technology to be used.
• B. The frequency at which team formation can be changed.
• C. The ability to go to market with a product release.
• D. Sprints must have the same length throughout an organization.
• E. The risk of being disconnected from the stakeholders.

正解：A、C、E

解説：
Sprint length in Scrum is a critical decision that impacts the team's ability to deliver value and adapt. The Scrum Guidestates that Sprints are fixed in length (typically one month or less) to create consistency and enable regular inspection and adaptation. While it doesn't explicitly list factors, practical application and Scrum principles suggest:
* A (The ability to go to market with a product release):Shorter Sprints allow faster feedback and releases, aligning with Scrum's focus on delivering value frequently.
* D (The level of uncertainty over the technology to be used):High uncertainty may warrant shorter Sprints to mitigate risk and validate assumptions, a key aspect of empirical process control.

質問 # 48
True or False: Scrum mandates the use of burndown charts.

• A. False
• B. True

正解：A

解説：
Scrum does not mandate specific tools like burndown charts; it focuses on outcomes (e.g., a "Done" Increment) rather than prescriptive practices. TheScrum Guidementions progress tracking as optional:
"Various practices exist to forecast progress, like burn-downs, burn-ups, or cumulative flows. While proven useful, these do not replace the importance of empiricism."
* A:False-burndown charts are optional.

質問 # 49
If the Product Owner is not collaborating with the Developers during the Sprint, what should the Scrum Master do? (Choose the best answer)

• A. Coach the Product Owner on the values and benefits of Scrum and incremental delivery
• B. Cancel Scrum until a better Product Owner is identified
• C. Escalate to senior management

正解：A

解説：
The Scrum Master serves the Product Owner by fostering Scrum adoption: "The Scrum Master serves the Product Owner in several ways, including... Helping find techniques for effective Product Goal definition and Product Backlog management." If collaboration is lacking, coaching (C) aligns with this role, emphasizing Scrum's collaborative nature and incremental value delivery.
* A:Escalation bypasses the Scrum Master's responsibility to resolve issues.

質問 # 50
What are the purposes of the Definition of "Done"? (Choose the best two answers)

• A. Help ensure the Increment is releasable
• B. Provide transparency
• C. Document the Sprint Goal
• D. Ensure unit testing occurs

正解：A、B

解説：
The Definition of "Done" ensures quality and clarity. TheScrum Guidestates: "The Definition of Done is a formal description of the state of the Increment when it meets the quality measures required for the product."
* A:It ensures the Increment is usable/releasable: "In order to provide value, the Increment must be usable."
* B:It provides transparency by setting a shared standard: "The Definition of Done creates transparency by providing everyone a shared understanding of what work was completed."
* C:The Sprint Goal is separate, defined in Sprint Planning.

質問 # 51
The process of regular inspection and adaptation employs knowledgeable and skilled inspectors. What are two ways in which the Product Owner takes the lead in the inspection process? (Choose the best two answers)

• A. At the end of Sprint Planning the Product Owner verifies the Sprint Backlog for completeness in order to allow the Sprint to start.
• B. At the Sprint Review the Product Owner shares the current state of Product Backlog, which, combined with the inspection of the Increment, leads to an updated Product Backlog.
• C. At the Daily Scrum the Product Owner inspects the Sprint burn-down for progress towards a complete Increment and re-planning the team's work.
• D. The Product Owner invites stakeholders to the Sprint Review to learn how the current state of the marketplace influences what is the most valuable thing to do next.

正解：B、D

解説：
The Product Owner leads inspection related to value and backlog management:
* A:At the Sprint Review, they present the Product Backlog state, adapting it based on Increment feedback, per: "The Product Owner discusses the Product Backlog as it stands."
* D:Inviting stakeholders ensures market insights inform value, aligning with: "The Product Owner may invite other people to attend."
* B:Daily Scrum is for Developers; the Product Owner doesn't inspect burn-downs there.

質問 # 52
When is a Sprint finished? (Choose the best answer)

• A. When the time-boxed duration is met
• B. When the work remaining is zero
• C. When the Definition of Done is met
• D. When the Product Owner accepts the Increment

正解：A

解説：
A Sprint is a fixed-length, time-boxed event that ends when its duration expires, regardless of work completion. TheScrum Guidestates: "Sprints are the heartbeat of Scrum, where ideas are turned into value.
They are fixed length events of one month or less to create consistency." The end is determined by the time- box, not by acceptance, quality standards, or task completion.
* A:Product Owner acceptance occurs at Sprint Review, but doesn't define Sprint end.
* B:The Definition of "Done" applies to the Increment, not the Sprint's duration.
* C:Correct-the time-box dictates the end.

質問 # 53
The Product Owner's authority to change and update the Product Backlog is unlimited, except for: (Choose the best answer)

• A. Nothing. The entire organization must respect a Product Owner's decisions.
• B. Technical and architectural work that needs to be done first, as indicated by the chief enterprisearchitect.
• C. Decisions by the CFO, the CEO, or the board of directors.
• D. Work for which impediments exist that the Scrum Master still needs to resolve.
• E. High impact changes that have not been approved by the change request board.
• F. Decisions by the chief program manager.

正解：A

解説：
TheScrum Guidegrants the Product Owner sole authority over the Product Backlog: "The Product Owner is one person, not a committee... For Product Owners to succeed, the entire organization must respect their decisions." No external roles or processes override this.
* A, C, D, E:These introduce roles (CFO, CEO, program manager, architect, change board) not recognized in Scrum as limiting the Product Owner's authority.
* F:Impediments affect execution, not the Product Owner's right to update the backlog.

質問 # 54
A Product Owner is entitled to postpone the start of a new Sprint after the conclusion of a previous Sprint for the following reason: (Choose the best answer)

• A. The stakeholders are not happy with the value produced in the previous Sprint.
• B. The QA department needs more time to make the previous Increment "Done".
• C. Not enough Product Backlog items are "Ready".
• D. The Product Owner has not identified a Sprint Goal.
• E. There is no acceptable reason. A new Sprint starts immediately after the conclusion of the previous Sprint.

正解：E

解説：
In Scrum, Sprints are continuous and fixed-length, with no gaps allowed between them. TheScrum Guide explicitly states: "A new Sprint starts immediately after the conclusion of the previous Sprint." This ensures a consistent cadence of delivery and adaptation, a cornerstone of Scrum's empirical process. Let's examine each option:
* A (Not enough "Ready" items):The Product Backlog can be refined incrementally; a lack of "Ready" items doesn't justify delaying a Sprint. The team can start with what's available and refine further during the Sprint.
* B (No Sprint Goal):The Sprint Goal is defined during Sprint Planning, not beforehand. Its absence pre- Sprint isn't a valid delay reason.
* C:This aligns with theScrum Guide's mandate for immediate succession, making it correct.
* D (QA needs more time):Scrum rejects external dependencies like a separate QAdepartment; the Developers must deliver a "Done" Increment within the Sprint. Delaying contradicts this.

質問 # 55
What is typical work for a Product Owner in a Sprint? (Choose the best two answers)

• A. Work with the Developers on Product Backlog refinement.
• B. Update the work plan for the Developers on a daily basis.
• C. Attend every Daily Scrum to answer functional questions on the discussed Sprint Backlog items.
• D. Collaborate with stakeholders, user communities, and product managers.
• E. Create financial reporting upon the spent hours reported by the Developers.

正解：A、D

解説：
TheScrum Guideoutlines the Product Owner's responsibilities as maximizing value through Product Backlog management, which includes:
* C:"Developing and explicitly communicating the Product Goal" and refining the Product Backlog with Developers to ensure clarity and readiness.
