Which of the following best describes an increment of working software?
Answer(s): B
According to the Scrum Guide1, an Increment is a concrete stepping stone toward the Product Goal. Each Increment is additive to all prior Increments and thoroughly verified, ensuring that all Increments work together. In order to provide value, an Increment must be usable. Multiple Increments may be created within a Sprint. The sum of the Increments is presented at the Sprint Review thus supporting empiricism. However, an Increment may be delivered to stakeholders prior to the end of the Sprint. The Sprint Review should never be considered a gate to releasing value. Therefore, the best description of an increment of working software is additional features in a usable state that complement those delivered in previous iterations.

The Product Owner determines how many Product Backlog items the Development Team selects for a Sprint.
Answer(s): A
The correct answer is A, because the Product Owner does not determine how many Product Backlog items the Development Team selects for a Sprint. 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.
Which three of the following are feedback loops in Scrum? (Choose three.)
Answer(s): A,C,E
The correct answers are A, C, and E, because these are feedback loops in Scrum. The Sprint Review is a feedback loop that allows the Scrum Team and the stakeholders to inspect the Increment and adapt the Product Backlog. The Sprint Retrospective is a feedback loop that allows the Scrum Team to inspect itself and create a plan for improvements. The Daily Scrum is a feedback loop that allows the Development Team to inspect its progress and plan its work for the next 24 hours.
When a Development Team is having trouble delivering a working Increment because they don't understand a functional requirement, what should they do?
Answer(s): C
The correct answer is C, because when a Development Team is having trouble delivering a working Increment because they don't understand a functional requirement, they should collaborate with the Product Owner to determine what is possible and acceptable. The Scrum Guide states that "the Product Owner is responsible for maximizing the value of the product resulting from work of the Development Team. How this is done may vary widely across organizations, Scrum Teams, and individuals." Therefore, the Product Owner should clarify the functional requirement and negotiate the scope of work with the Development Team.
