NEW QUESTION 63
During the sprint the developers realize that they have selected too many product backlog items. How should they go from there?

Inform the product owner and the stakeholders during the sprint review

As soon as they realize they should work with the product owner to remove some work while not endangering the sprint goal

Outsource the work to another team

Use a definition of done with lower standards to be able to finish all the work they committed to

Never should they reduce the DoD. They should be able to do the work their selves and therefore work with the product owner to reduce the scope. Since the product owner is responsible for maximizing value and making priorities, he is the go to person for matteres like this.

Code with low cyclomatic complexity

Code with minimal duplication

Code that has not been peer reviewed (yet)

Code that has been peer reviewed

DRY, don’t repeat yourself

NEW QUESTION 65
What is the role of modeling in scrum teams?

Models are not used by agile teams

Models are maintained along with the software as it emerges

Models are assembly instructions for the developers

Modeling may be useful to increase shared understanding

Models are in no way mandatory, however their value as increasing shared language is acknowledged.

NEW QUESTION 66
Which of the following describes an architecture spike?

A fundamental architectural problem found in an existing application

The result of an exhaustive architectural planning effort

A small development activity to learn about technical elements of a proposed solution

A decision made by a systems architect to settle disagreement amongst the developers

An architecture spike is a small development activity to learn about technical elements of a proposed solution.

NEW QUESTION 67
What statement best describes the product backlog?

It is an emergent, ordered list of what is needed to improve the product

It is the diary of the product owner

It is mainly meant as inspiration for the sprint planning

It is a list of all the requirements that will have to be added to the product

It is not fixed, it is a live artifact that will grow and change as more is learnt. The product owner orders it by value.

NEW QUESTION 68

During the sprint planning when they can’t fit enough into the sprint

Prior to starting a new sprint

In the retrospective when it turns out they can improve quality

Prior to starting a new project

The definition of done can be changed when more is learnt. This always needs to be done aiming at a high quality usable increment. The best time to reflect on this is the retrospective.

NEW QUESTION 69
Which best describes the practice of expressing requirements as acceptance tests?

Regression testing

Acceptance test driven development

Objective Driven Development

Quality Oriented Requirements Development

This is pretty much the definition of ATDD.

NEW QUESTION 70
What activities would a Product Owner typically undertake in the phase between the end of the current sprint and the start of the next sprint?

Work with the QA departments on the increment of the current sprint

There are no bugs in the application

At least 50% of the application is working correctly

You did not break any of the unit tests that already existed

You can’t really say anything because you don’t know what the unit tests are testing and whether they are correctly representing whether the application is working correctly. However, if all the tests passes you didn’t break any already existing tests. Also, if none tests existed yet, you did not break them.
