質問 # 37
What is code coverage? (choose the best answer)
- A. The degree to which the system under test has been exercised by tests.
- B. The number of Developers that understand how the code works.
- C. An insurance policy that covers the code for defects.
- D. The percentage of code in version control included in a build.
正解：A
解説：
Detailed Explanation: Code coverage measures the percentage of code executed during testing. It helps identify untested parts of a codebase, ensuring better quality and fewer defects.
質問 # 38
Who owns the Sprint Backlog? (choose the best answer)
- A. The Product Owner.
- B. The Scrum Team.
- C. The Scrum Master.
- D. The Developers.
正解：D
解説：
Detailed Explanation: The Developers own the Sprint Backlog as it represents their plan for achieving the Sprint Goal. They update it throughout the Sprint to reflect their progress.
質問 # 39

- B. A mock is a way to initialize the database for testing
- C. A mock helps you create a build script

正解：A
質問 # 40
Which metric is least useful when measuring code maintainability?
- A. Function points
- B. Depth of inheritance
- C. Cyclometic complexity
正解：A
解説：
The other two are good metrics. Function points are the points representing the amount of business functionality.
質問 # 41
Which of the following are advantages of Continuous Integration? (choose the best two answers)
- A. Readability of code is improved.
- B. Know immediately how a change affected the product.
- C. Reduce effort and risk when integrating changes.
- D. The feature-branch is generally kept in a buildable state.
正解：B、C
解説：
Detailed Explanation: Continuous Integration ensures that changes are integrated and tested frequently, providing immediate feedback on their impact. It reduces the effort and risks associated with late integrations.
質問 # 42
Choose three reasons why automated builds are important.
- A. The eliminate the need for build engineers
- B. They clearly define the build process
- C. They support Continuous Integration
- D. They allow frequent validation and ensure the product remains in a potentially releasable state
- E. They ensure your product remains bug free
正解：B、C、D
解説：
Automated builds are making builds of the code after every change to the codebase. As soon as something breaks, the developers get informed. In order to automate it, the build process needs to be cleary defined. They're a corner stone for CI.
質問 # 43
When a continuous integration build fails, who should fix it?
- A. The person who is responsible for configuration management within the team
- B. The next person who needs the build to complete successfully
- C. The person who broke the build
- D. The tester responsible for validating builds
正解：C
解説：
The build should be fixed asap, the first person to notice is the person who broke it. This person usually best understands why and is therefore the best person to fix it.
質問 # 44
In software development DRY refers to:
- A. Code with minimal duplication
- B. Code that has been peer reviewed
- C. Code with low cyclomatic complexity
- D. Code that has not been peer reviewed (yet)
正解：A
解説：
DRY, don't repeat yourself
質問 # 45
Which three of the following are code quality metrics?
- A. Depth of inheritance
- B. Number of check-ins per day
- C. Class coupling
- D. Cyclomatic complexity
- E. Cycle time per product backlog item
- F. Unit tests per class
正解：A、C、D
解説：
Number of checkins per day says something about whether the developers are committing often enough.
Depth of inheritance says some about complexiity, just like class coupling and cyclomatic complexity. Unit tests per class don't say anything about quality, though no unit tests might indicate a maintenance problem.
Cycle time per product backlog item says something about the scrum process.
質問 # 46
True or False: A high-performance Scrum Team ensures that each Increment is complete by running a Release Sprint.
- A. False
- B. True
正解：A
解説：
Detailed Explanation: Scrum does not have a concept of a "Release Sprint." Each Sprint must result in a Done Increment, which may be released as required. The focus is on continuous delivery of value, not specific release cycles.
質問 # 47
Which phrase best describes a product owner?
- A. Project manager
- B. Requirements engineer
- C. Mediator for the developers and customers
- D. Value optimizer
- E. Team manager
正解：D
解説：
The scrum guide says: "The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team." The key here is the value maximizing part. Of course, he also comes up with requirements and acts as a go-between between developers and customers, but that is definitely not the best answer here.
質問 # 48
In what ways do Developers contribute to refining the Product Backlog? (choose the best three answers)
- A. They ask questions to clarify the intent of Product Backlog items.
- B. They do not. The Developers are only responsible for prioritizing technical work.
- C. They give input on technical dependencies.
- D. They may update estimates for Product Backlog items.
- E. They do not. The Scrum Master and the Product Owner are responsible for Product Backlog refinement.
正解：A、C、D
解説：
Detailed Explanation: Developers actively participate in Product Backlog refinement by updating estimates, identifying technical dependencies, and asking clarifying questions to ensure shared understanding.
質問 # 49
Which three describe TDD?
- A. An incremental and emergent approach to software design
- B. Creating a manual test script before writing code
- C. A predictable way to develop working well-organized code
- D. Having testers involved in the development process
- E. A software development technique based on automated tests
正解：A、C、E
解説：
TDD stands for test driven development. It makes developers think before starting to code. This leads to better organized code. It requires the developer to write the code for the test first, this means that it's based on automated tests. There are no testers in scrum, they are called developers as well.
質問 # 50
Which output from sprint planning provides the developers with a target and overarching direction for the sprint?
- A. The product goal
- B. The Sprint goal
- C. The sprint backlog

- A. All of these
- B. The scrum process
- C. Coding and engineering practices

質問 # 52
Which of the following best describes Emergent Architecture? (choose the best answer)
- A. An approach to make decisions easier to change in the future and find the best possible point in time to make decisions.
- B. Enterprise Architects must be involved to create the foundation of each software product.
- C. In Scrum there is no Architect-Role; therefore, architecture emerges naturally.
- D. Starting development of a software product requires a clear understanding of the underlying software architecture, and Emergent Architecture describes the process of creating this final architecture.
- E. The software architecture emerges solely from decisions the Developers make from a technical perspective.
正解：A
解説：
Detailed Explanation: Emergent Architecture emphasizes deferring decisions until the last responsible moment, enabling better adaptability and minimal waste in a complex, ever-changing environment, as per Agile principles.
質問 # 53
Why are automated builds important?
- A. You are unable to check in code without them
- B. They help you find defects and configuration management issues
- C. Without them you can't tell if your code works
- D. They are part of the Definition of Done
正解：B
解説：
Automated builds will be made every time the code base gets changed. If a change to the code base breaks the build, the developers get informed immediately and can fix the build again without drifting off to far.
質問 # 54
Which concept is described by the Last Responsible Moment? (choose the best answer)
- A. The last moment a Developer is responsible for quality; after this, the Tester is responsible.
- B. Discover decisions to be made as soon as possible but postpone making those decisions until the latest reasonable moment.
- C. The last moment in a Sprint when code changes are allowed; after this, only stabilization work should be conducted.
- D. Making decisions as soon as possible to close feedback loops as soon as possible.

When more teams are working on the same product. How should they go about their definition of done?
- A. Every team must make their own DoD, a meeting should be organised so that the differences are known.
- B. All development teams must have a DoD that makes their combined work releasable.
- C. Every team uses its own. The differences are discussed in a hardening sprint.
- D. It depends on the product owner
正解：B
解説：
The product must be releasable and done must mean the same for all additions to the product. So they must have a DoD that can combined. There is no hardening sprint.

- A. Whenever the product owner asks
- B. During the sprint review
- C. All of these
- D. Anytime the developers need feedback from the product owner
