What is true about the Definition of Done?

2. All Sprints of a project have the same DoD

The Scrum Guide says:

"During each Sprint Retrospective, the Scrum Team plans ways to increase product quality by adapting the definition of “Done” as appropriate."

Can any of the four answers therefore be said to be true?

I choose 1.The DoD of a Sprint is unique and depends on the content and purpose of the Sprint

There should be only one DoD in a Sprint.
DoD should be confirmed during Scrum planning.

DoD should be confirmed during Scrum planning.

Sorry!
I want to say "DoD should be confirmed during Spring planning."

I am agree with Ian's comments but out of given four option, 1st one looks most apposite.

"During each Sprint Retrospective, the Scrum Team plans ways to increase product quality by adapting the definition of “Done” as appropriate."

What does adapting the definition of “Done” as appropriate mean?
As Scrum Teams mature, it is expected that their definitions of “Done” will expand to include more stringent criteria for higher quality.
For example:
In order to increase product quality, we must add the following criteria to the definition of “Done”:
1. For UI Application, it must pass a 4-hours Exploratory test.
2. For Windows service, it must take an stable running for 48 hours.
3. The code coverage must be raised from 80% to 90% average.
4. The code coverage of buniness logic componet developed via TDD must be 100% from now on.
5. …

On the other hand:
The purpose of each Sprint is to deliver Increments of potentially releasable functionality that adhere to the Scrum Team’s current definition of “Done.”
During sprint planning, The Development Team works to forecast the functionality that will be developed during the Sprint. The Product Owner discusses the objective that the Sprint should achieve and the Product Backlog items that, if completed in the Sprint, would achieve the Sprint Goal.

I think the definition of “Done.” Includes both features and quality and must be confirmed during Sprint planning.

So, the answer is the First One.

1. The DoD of a Sprint is unique and depends on the content and purpose of the Sprint.

The DoD doesn't depend on the "content and purpose of the Sprint", even when it is improved each Sprint. Rather, it depends on the quality and purpose of the expected release.

It's the Sprint Goal that depends upon the "content and purpose of the Sprint", in so far as it should express a coherence of these things.

None of the answers are satisfactory in my view.

I'm on your side.

But as s test taker, I would choose the First One. :)

Does anyone know where this question actually comes from, and to which test it is meant to relate?

Hi! This question comes from europeanscrum.org - it's Scrum & Scrum Master Exam Simulator

This example shows that coming up with good questions can be harder than coming up with good answers.

And this thread shows that essay questions are much more interesting than true/false questions ! ;-)

Yes, I couldn't agree with you more.

But there would be a trade-off for non-native English speaker like me.

Essay questions would be a big problem for me!
