Your development team uses Scrum as its process framework.
You are attempting to increase efficiency, code quality, and limit scope creep by making some changes to your team's development process.
You need to identify key metrics for measuring the effect of any changes to your process.
Which three key metrics should you use? Each correct answer presents part of the solution.

• A. number of bugs reported by testers
• B. number of items added to the product backlog
• C. number of tasks added to the sprint after the sprint starts
• D. number of classes in the code-base
• E. number of manual test cases created
• F. number of story points delivered during the sprint

You are planning to develop a new application.
You need to ensure that the code is easy to test and obtain high code coverage.
What should you do?

• A. Create as many static methods as possible.
• B. Ensure that concrete classes depend only on other concrete classes.
• C. Create a fake for each class that you are testing.
• D. Ensure that each class has only one responsibility.

DRAG DROP
Your team uses Microsoft Visual Studio Team Foundation Server (TFS) to manage the software development process. You are using the Microsoft Visual Studio Scrum process template on your TFS Team Project.
Your product owner adds new product backlog items to your backlog.
You need to estimate how many sprints are necessary to complete the work in your backlog.
You have set a value for the Effort field for each product backlog item found in your backlog as a first step.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

You are developing an n-tier application. An architect has provided a layer diagram as shown in the exhibit image. (Click the Exhibit button.)

Your code is built as part of an automated team build.
A class in the data access layer is changed to utilize a utility class that resides in the business logic layer.
You need to ensure that the code and layer diagram are valid in a manner that follows good architectural and object oriented practices.
What should you do?

• A. Create a new cross-cutting layer and refactor the utility class into the new layer, allowing the new layer to reference both the data access layer and the business logic layer.
• B. Change the dependency between the data access layer and the business logic layer to be bi-directional.
• C. Create a new cross-cutting layer and refactor the utility class into the new layer, allowing the data access layer and business logic layer to have one-way dependencies to the new layer.
• D. Leave the layers the same and duplicate the utility class in both the data access layer and the business logic layer.
