NO.47 Who owns the Sprint Backlog? (choose the best answer)

The Product Owner.

The Scrum Team.

The Scrum Master.

The Developers.

Detailed Explanation: The Developers own the Sprint Backlog as it represents their plan for achieving the Sprint Goal. They update it throughout the Sprint to reflect their progress.

NO.48 Choose three reasons why automated builds are important.

They support Continuous Integration

The eliminate the need for build engineers

They ensure your product remains bug free

They clearly define the build process

They allow frequent validation and ensure the product remains in a potentially releasable state

Automated builds are making builds of the code after every change to the codebase. As soon as something breaks, the developers get informed. In order to automate it, the build process needs to be cleary defined. They’re a corner stone for CI.

NO.49 What are some disadvantages of code coverage as a measure for how well a system or product is tested? (three answers)

It does not measure usability

It is too complicated to explain to management

It only provides insights to programmers

It does not ensure that the most important or highest risk areas of the code are being exercised by tests

It could create incentives to write tests that simply increase code coverage, rather than tests that find bugs without increasing code coverage

Not being able to explain to management should never be the reason to not do it. It doesn’t only provide some data to programmers, the problem is that code coverage alone is not meaning a lot.

NO.50 What are the developers responsible for? (choose two)

Resolving conflicts amongst the developers

Selecting the product owner

Organizing work required to meet the sprint goal

Reporting productivity

They are concerned with everything that needs to happen to create a working increment. And they are self-managing, so resolving conflicts is something they should arrange as well.

NO.51 Upon what type of process control is scrum based?

Deductive

Hybrid

Empirical

Technical

If you are not sure, please review the Scrum theory section in the scrum guide

NO.52 How long is the daily scrum?

The scrum master ends the meeting when it is done

This is for the developers to decide

At most 15 minutes

At least 15 minutes

Around 15 minutes, but more if necessary

The timebox for the daily scrum is 15 minutes. The timebox doesn’t say anything about a minimum length, just about a maximum length.

NO.53 You are asked to refactor part of the codebase for an application. When you are done, all unit tests pass with 50% code coverage. What can you infer from this?

Less than 50% of the application is working correctly

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.

NO.54 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.

NO.55 What is the size of the scrum team?

typically 10 or fewer people

this differs every sprint

at least 8 people

3 to 11

The scrum guide says: “The Scrum Team is small enough to remain nimble and large enough to complete significant work within a Sprint, typically 10 or fewer people. “

NO.56 Which phrase best describes a product owner?

Team manager

Project manager

Requirements engineer

Mediator for the developers and customers

Value optimizer

The scrum guide says: “The Product Owner is accountable for maximizing the value of the product resulting from the work of the Scrum Team.” The key here is the value maximizing part. Of course, he also comes up with requirements and acts as a go-between between developers and customers, but that is definitely not the best answer here.

NO.57 What are possible benefits from practicing Test-Driven Development? (choose the best three answers)

It is a great way for Testers to contribute early in the Sprint as they can start creating all the tests from the beginning.

It increases collaboration between Developers as it requires Pair Programming.

It helps to identify gaps in understanding the desired behavior.

It might lead to better code as refactoring is part of the Test-Driven Development cycle.

It helps break down complex problems into smaller ones that are much easier to be tackled.

It makes Integration Tests obsolete and by doing so saves a lot of time.

Detailed Explanation: Test-Driven Development (TDD) helps identify gaps in understanding by requiring tests that outline the desired behavior. Refactoring ensures better code quality, and breaking problems into smaller units makes them manageable.

NO.58 What is a sprint burn down chart?

Visual representation of work that is still to do and time that is left

A chart showing progress towards the product goal

A chart that shows whether bugs came up

Visual representation of the product backlog items left

NO.59 Your team is one of seven teams working on a product. All teams use the same version control system. Which is the best approach to deliver high-quality increments?

Each team’s automated build is integrated toward the end of the sprint

Developers should perform a combination of local and private builds

Each team should have its own automated build

There is one automated build for all teams

This way there are no surprises near the end of the sprint or during delivery and the increment will be most stable as possible.

NO.60 What are the scrum values?

commitment, empiricism, focus, respect

commitment, focus, respect, transparency and courage

transparency, inspection, adaptations

commitment, focus, openness, respect and courage

NO.61 Which are obligatory scrum events?

sprint retrospective

sprint goal meeting

backlog refinement

sprint planning

sprint review

daily scrum

If you are not sure, please review the Scrum events section in the scrum guide

NO.62 Which three of the following are code quality metrics?

Unit tests per class

Cycle time per product backlog item

Number of check-ins per day

Depth of inheritance

Cyclomatic complexity

Class coupling

Number of checkins per day says something about whether the developers are committing often enough.
Depth of inheritance says some about complexiity, just like class coupling and cyclomatic complexity. Unit tests per class don’t say anything about quality, though no unit tests might indicate a maintenance problem.
Cycle time per product backlog item says something about the scrum process.
