NEW QUESTION 20
Cyclomatic complexity is a metric for:
- A. Measuring branching structures and nesting levels in code
- B. Assessing if code is written in as few lines as possible
- C. Demonstrating code is well structured and cleanly implemented
- D. Determining the number of unit tests required to ensure correctness
Answer: A
Explanation:

- A. A fundamental architectural problem found in an existing application
- B. A decision made by a systems architect to settle disagreement amongst the developers
- C. A small development activity to learn about technical elements of a proposed solution
- D. The result of an exhaustive architectural planning effort

Answer: A
NEW QUESTION 23
Which three of the following are feedback loops in scrum?
- A. Release planning
- B. Sprint review
- C. Sprint retrospective
- D. Daily scrum
- E. Refinement meeting
Answer: B,C,D
Explanation:
Refinement meeting and release planing are no scrum events. The others are, and they are all about feedback: inspection and adaptation. (And in order for the inspection to have a good outcome, the artifacts need to be transparent)
NEW QUESTION 24
The right time to refactor code using TDD is
- A. When preparing legacy code for unit tests
- B. After the tests fails
- C. When I can see the debt building in the code
- D. After the tests passes
Answer: D
Explanation:
You should refactor as soon as possible, but before the tests passes it cannot be refactored, because then it is not esatablished just yet. So it would still be part of the first version if changes would be made then.

NEW QUESTION 27
Which are two benefits of establishing naming conventions for code?
- A. To ensure that orphan functions are not created
- B. To make the code more readable
- C. To communicate the identity of the developer that wrote the code
- D. To make it easy to distinguish between different software products
- E. To reduce friction in a shared codebase
Answer: B,C

- B. A chart showing progress towards the product goal
- C. Visual representation of the product backlog items left
- D. Visual representation of work that is still to do and time that is left
Answer: D
NEW QUESTION 29
Which three of the following are code quality metrics?
- A. Cyclomatic complexity
- B. Number of check-ins per day
- C. Class coupling
- D. Depth of inheritance
- E. Unit tests per class
- F. Cycle time per product backlog item
Answer: A,C,D
Explanation:
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.
NEW QUESTION 30

- A. Code with minimal duplication
- B. Code that has not been peer reviewed (yet)
- C. Code with low cyclomatic complexity

Select three criteria for the definition of done
- A. The product is released at the end of every sprint
- B. Regression tests pass
- C. Code review is done
- D. Acceptance tests pass
- E. Code coverage 90%
Answer: B,C,D
Explanation:
Releasing the product at the end of the sprint doesn't relate to one item and when it's done. Code coverage does, but it's the worst criteria in this list, because it's a stimulus to write tests that cover a lot of lines rather than cover the functionality.
NEW QUESTION 35
