NEW QUESTION 59
When are testers and QA experts ideally included in the project?
- A. When the developers are done
- B. After every sprint review
- C. From the beginning and throughout the sprints, but let's call them developers

- A. Design the full architecture before starting
- B. Work together and self manage to create value
- C. Creating a plan for the entire project

Architecture emerges in scrum during the adding of functionality. The plan for the rest of the project cannot be made by the developers, they should just focus on their sprint.
NEW QUESTION 61
Which three describe TDD?
- A. A predictable way to develop working well-organized code
- B. Having testers involved in the development process
- C. A software development technique based on automated tests
- D. An incremental and emergent approach to software design
- E. Creating a manual test script before writing code
Answer: A,C,D
Explanation:
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.

- B. Code being exercised by tests
- C. The quality of unit tests being written
- D. The ratio of the number of tests to lines of code in the system being tested
- E. The absence of defects in code
Answer: B
Explanation:
The ratio answer is wrong, because it doesn't say anything about the number of tests to lines of code, but it does say the percentage of lines of code that is being tested. Hence, the correct answer is code being exercised by tests.
NEW QUESTION 70
How is architecture decided in a scrum team during a project?
- A. The architect works in the early part of each sprint to define the architecture of that sprint
- B. An architect on the team undertakes all architecture tasks

- B. They clearly define the build process
- C. They ensure your product remains bug free
- D. The eliminate the need for build engineers
- E. They allow frequent validation and ensure the product remains in a potentially releasable state
Answer: A,B,E
Explanation:
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.
NEW QUESTION 78
What are three of the best ways to address non-functional requirements?

Answer: B,C,E
Explanation:
There is no hardening sprint, there are only regular sprints. If it's an ever recurring non-functional requirement, it can be added to the definition of done. If it's not it can be added (as a criteria) in the product backlog (item).
