PSD Scrum Professional Scrum Developer 1 (PSD I) Free Practice Exam Questions (2025 Updated)

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.

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.

Hiding the bug won't make it go away. Discussing with the product owner is a good step to take, because he knows what work leads to maximum value.

Detailed Explanation: Security ensures the application protects data and systems, while scalability ensures it can handle increased loads efficiently. These are key quality attributes for a robust application architecture.

This is not a decision the CEO or the developers can make, this should go via the PO, since that is the maximumizer of value

Merging means combining two different versions of the code into one version.

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.

Detailed Explanation: User Stories are not required in the Product Backlog as per the Scrum Guide. The Product Backlog is a collection of all work to be done on the product, and it can include a variety of formats, such as tasks, features, and technical requirements, not just user stories.

Detailed Explanation: The Definition of Done ensures an Increment is releasable and provides transparency. It can be refined over time to enhance quality, and its application can be reviewed during Retrospectives.

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.

Never should they reduce the DoD. They should be able to do the work their selves and therefore work with the product owner to reduce the scope. Since the product owner is responsible for maximizing value and making priorities, he is the go to person for matteres like this.

It should be a working increment, but it's not mandatory to release it.

This way there are no surprises near the end of the sprint or during delivery and the increment will be most stable as possible.

It is false, the developers select the items, because they will have to commit to it.

The product owner can cancel the sprint if the sprint goal becomes obsolete. This is a very rare event. It can happen when a company losing a client or the client decides to take a completely different turn.

Detailed Explanation: Product documentation can be part of a Done Increment if it adds value and meets the Definition of Done. Scrum does not prescribe documentation but emphasizes delivering value to stakeholders.

Detailed Explanation: Automated test harnesses include Functional, Unit, Integration, and Performance tests to ensure robust and reliable quality control. Exploratory and manual tests are typically not automated.

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.

Detailed Explanation: Scrum promotes self-management by empowering the team to decide what work they take on, removing hierarchical titles to foster equality and collaboration, and having the Scrum Master shield the team from external disruptions so they can focus on their goals.
