The correct answer is B, because the Product Owner does not make sure the team selects enough from the Product Backlog for a Sprint to satisfy the stakeholders. The Scrum Guide states that “the number of items selected from the Product Backlog for the Sprint is solely up to the Development Team. Only the Development Team can assess what it can accomplish over the upcoming Sprint.” Therefore, the Development Team is responsible for choosing the scope of work for a Sprint.

The Developers determine how many Product Backlog items they select for a Sprint, as stated in the Scrum Guide: “The Developers select items from the Product Backlog to include in the current Sprint. The Scrum Team may refine these items during this process, which increases understanding and confidence.”

The correct answer is D. 10 or fewer. According to the Scrum Guide 20201, “The Scrum Team is small enough to remain nimble and large enough to complete significant work within a Sprint, typically 10 or fewer people.” The other options are outdated or incorrect. Option A was based on the previous version of the Scrum Guide, which suggested a range of 3 to 9 developers2. Option B is too vague and does not account for the upper limit of team size. Option C is too specific and does not allow for flexibility.

The correct answer is B, because the Scrum Guide states that “at the end of a Sprint, the new Increment must be ‘Done,’ which means it must be in useable condition and meet the Scrum Team’s definition of ‘Done’. An increment is a body of inspectable, done work that supports empiricism at the end of the Sprint. The increment is a step toward a vision or goal.” Therefore, all the increments from different Scrum Teams working on the same product should be integrated every Sprint to enable inspection and adaptation by the Product Owner and stakeholders.

According to the Scrum Guide, the timebox for a Sprint Planning event is 8 hours for a one-month Sprint, proportionally shorter for shorter Sprints. The other options are not valid, as they are either too long (such as monthly), too vague (such as whenever it’s done), or too short (such as 4 hours for a one-month Sprint).

The Sprint Backlog is the Development Team’s plan for the Sprint, as stated in the Scrum Guide1: “The Sprint Backlog is a plan with enough detail that changes in progress can be understood in the Daily Scrum. The Development Team modifies the Sprint Backlog throughout the Sprint, and the Sprint Backlog emerges during the Sprint.”

The correct answer is C, because the second Sprint starts immediately after the first Sprint. The Scrum Guide states that “Sprints have consistent durations throughout a development effort. A new Sprint starts immediately after the conclusion of the previous Sprint.”
