Question 1

The practice of decomposing a requirement into failing tests is called:

ABehavior driven development

BScrum testing

CRegression testing

DAcceptance test driven development

Answer : D

In ATDD you start with writing tests to represent the requirement. Since you start with this, there is no production code to satisfy the test which is why the tests will fail.

Question 2

What relation does scrum have to development practices?

AScrum requires a specific set of development practices

BScrum is complemented by good development practices

CScrum requires all development practices

DScrum has no relationship to development practices

Answer : B

Scrum requires no development practices, but good development practices do help and make scrum more successful.

Question 3

True or False: An Increment must be released to customers or users at the end of each Sprint.

ATrue

BFalse

Answer : B

While each Increment must meet the Definition of Done and be potentially releasable, releasing it is not mandatory. The decision to release lies with the Product Owner and stakeholders.

Question 4

What are two responsibilities of testers in the scrum team? (choose two)

AFinding bugs

BTracking quality metrics

CAll developers are responsible for quality

DVerifying the work of the programmers

EScrum has no tester role

Answer : C, E

Specific roles don't exist in scrum, developers are creating the value.

Question 5

Several scrum teams share the scrum master. Developers of multiple teams approach the scrum master, because they need fulltime commitment from the same technical specialist for the next sprint. What should the scrum master consider for the response to this problem? Choose the two best answers.

AThe need for a stable velocity

BThe benefit of the teams figuring it out theirselves

CThe need to have all developers busy with work

DThe ability of the scrum teams to produce integrated increments

Answer : B, D

The working increment is the goal of the sprint and should be kept in mind. The self-managing aspect of the teams is also crucial to take in mind. Stable velocity and optimally used developers are not the scrum master's concern.

Question 6

A team has expressed requirements as a set of failing acceptance tests. What are three benefits? (choose the best three answers)

AImproves quality in the requirement itself.

BPromotes the use of the DRY principle.

CTracking of completeness.

DUsing a code generation tool, the solution can be generated from the requirements model.
