Scrum Updated PSM-I Exam Questions and Answers by kacper

A Sprint burndown chart shows an estimate of the total work remaining for the Sprint, as stated in  3 : “A sprint burndown chart tracks work remaining in a sprint. It shows how much work remains at any given point during a sprint. It helps teams monitor whether they will finish all planned tasks by the end of a sprint.”

According to the Scrum Guide 1 , only people who are actively working on items in the Sprint Backlog participate in updating it during a Sprint; this includes tracking progress made on those items. This is typically done by Developers updating their remaining work every day after their Daily Scrum. The Development Team tracks this total work remaining at least for every Daily Scrum to project the likelihood of achieving their Sprint Goal. The Developers are self-organizing and decide how to turn Product Backlog items into an Increment of value. Therefore, the Scrum Master should allow the Development Team to self-manage and determine for itself what to do regarding the logistical challenges of meeting in different locations.

According to the Scrum Guide, estimates are made by the people doing the work, which is the Development Team. The Development Team is responsible for all estimates in the Product Backlog and the Sprint Backlog. The other options are not valid guidelines for estimating work in Scrum, as they are either too prescriptive (such as requiring story points or relative units), incorrect (such as forbidding estimating or having the Product Owner make estimates), or unnecessary (such as checking estimates with the Development Team).

The correct answer is D, because one of the services that a Scrum Master can provide in regard to the Daily Scrum is to teach the Development Team to keep the Daily Scrum within the 15 minute time-box. The Scrum Guide states that “the Scrum Master ensures that the Development Team has the meeting, but the Development Team is responsible for conducting the Daily Scrum. The Scrum Master teaches the Development Team to keep the Daily Scrum within the 15-minute time-box.”
