Scrum Updated PSM-I Exam Questions and Answers by sid

Architecture and infrastructure are handled in Scrum by implementing them along with functional development of the product, and by adding them to the Product Backlog and addressing them in early Sprints, while always requiring at least some business functionality, no matter how small, as stated in [2]: “Scrum does not distinguish between developing functionality or architecture. They are developed together, as they are both important and support each other. Architecture is not a separate phase; it is part of the product development. Architecture is added to the Product Backlog as any other feature or functionality.”

According to the Scrum Guide, the Sprint Backlog may include any items that are a decomposition of the selected Product Backlog items, such as user stories, tasks, use cases, tests, or others. The Sprint Backlog is the Developers’ plan for the Sprint, and it contains all the work that they forecast they can do to achieve the Sprint Goal and create a “Done” Increment. The other options are not valid, as they are either too specific (such as user stories or tasks) or too vague (such as tests).

The correct answer is B, because when multiple Scrum Teams work from the same Product Backlog, they should pull in work in agreement with the Product Owner. The Scrum Guide states that “multiple Scrum Teams often work together on the same product. One product goal unites them. Therefore, they must mutually define and comply with a definition of ‘Done’ that applies to their combined work product.” Therefore, they should collaborate and coordinate with each other and with the Product Owner to select Product Backlog items that align with their shared product goal.

The correct answer is A, because the best way the Scrum Master can ensure that the Development Team communicates effectively with the Product Owner is to monitor communications between them and facilitate direct collaboration. The Scrum Guide states that “the Scrum Master serves the Product Owner in several ways, including … facilitating Scrum events as requested or needed.” Therefore, the Scrum Master should help the Development Team and the Product Owner interact regularly and productively during the Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective events.
