Q1. 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. Leave the layers the same and duplicate the utility class in both the data access layer and the business logic layer.
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. Change the dependency between the data access layer and the business logic layer to be bi-directional.
Answer: C
Q2. You are utilizing the Microsoft Solution Framework (MSF) for Agile Software Development 6.0 process template.

A. Review team capacity.
B. From the Product Backlog view of the current sprint, review the By Work capacity bars for each contributor.
C. Review the task board.
D. Review the burndown chart.

Answer: ACE
Q3. Your development team uses the Microsoft Visual Studio Scrum 2.0 process template. You are the scrum master.
The product owner has created product backlog items and assigned them to a release.
You need to work with the development team to estimate when the release will be completed.
Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)
A. Review the sprint backlog.
B. Review the product backlog with the Forecast option set to on to determine if the release can be completed based on the team’s velocity.
C. Have the team create tasks for each item in the product backlog and assign hour estimates to the task.
D. Review the sprint burndown chart.
E. Set each team member’s per day capacity.
F. Establish a sprint duration and a sprint velocity. Create enough sprints to complete the release.
G. Estimate effort for each item in the product backlog.
Answer: BFG
Explanation: By using the forecasting tool in Web Access, you can plan the number of Sprints it will take to complete a set of work. The forecasting tool is available only in the Product Backlog, not any of the Sprint Backlogs. Prior to being able to use the forecasting tool, your Product Backlog must have PBI and Bug work items already created with the effort specified. You can turn on forecasting by clicking the Off hyperlink next to Forecast on the right side of the backlog page. The first time you do this, Web Access prompts you for the Velocity. Using your Development Team’s Velocity, Web Access will add a Forecast column and horizontal lines to the Product Backlog. In the Forecast column, it will display the Sprint that it predicts the PBI or Bug work item will be developed in.

Q4. Your development team uses the Microsoft Solution Framework (MSF) for Agile Software Development 6.0 process template.
You need to determine the process to obtain the most accurate estimates for each user story in your product backlog.
What should you do?
A. Have the development team estimate and use the longest estimates.
B. Ask the product owner to provide the estimates.
C. Ask the scrum master to provide estimates.
D. Have the development team estimate until team members reach consensus.
Answer: D
Q5. Your company network includes Microsoft Visual Studio Team Foundation Server (TFS) 2012 and Microsoft System Center 2012.
You need to monitor your company’s application infrastructure.
What should you configure?
A. Event Log data collector
B. Configuration Manager
C. Application Controller
D. IntelliSense collector
E. Operations Manager
Answer: E
Explanation: Operations Manager is a component of Microsoft System Center 2012 that helps the organization monitor services, devices, and operations for multiple computers from a single console. This guide leads the reader through the process of planning the Operations Manager infrastructure by addressing the following fundamental decisions and tasks:
.ullet Identifying which services, applications, and infrastructure need to be monitored.
.ullet Determining the resources needed to employ Operations Manager to monitor the selected resources.
.ullet Designing the components, layout, security, and connectivity of the Operations Manager infrastructure.
See "Microsoft System Center 2012 - Operations Manager Guide"
http://technet.microsoft.com/en-us/library/cc507089.aspx
Configuration Manager provides key management capabilities around application delivery, desktop virtualization, device management, and security that make it possible to enable productivity amidst device proliferation – while also reducing costs.
Application Controller provides a unified console that helps you manage public clouds and private clouds, as well as cloud-based virtual machines and services.
There is no such thing as IntelliSense collector.
Q6. Business analysts in your organization create large, extremely detailed requirements specifications.
Some business analysts report that developers are not delivering according to specifications.
You need to improve requirements management and delivery.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Require the business analysts to give the developers summaries of each requirement instead of the detailed specification.
B. Require the developers to prioritize requirements.
C. Use Microsoft PowerPoint storyboarding to improve the understanding of requirements.
D. Use the Feedback Manager tool to gather feedback from the business analysts regularly.
Answer: CD
Q7. A development team in your company has been unsuccessful delivering software by its deadline. You join the team as its new scrum master.
The previous scrum master did not understand the importance of the length of a sprint.
You need to define how long the sprints should be.
Which two factors should you consider to determine sprint length? (Each correct answer presents part of the solution. Choose two.)
A. The iteration length should be long enough to ensure than no more than 20 percent of the total effort is spent performing deployment and administrative tasks.
B. The iteration length should be consistent.
C. The iteration length should be flexible.
D. The sprint length should be long enough to create a usable and potentially releasable product.
E. The iteration length should be longer than one month.
Answer: BD
Explanation: Sprint length I asked Ken Schwaber once how long a Sprint should be. His answer was, “As short as possible and no shorter.” Sprints of longer than four weeks (one month) have a smell—the smell of water falling. When a Sprint’s length is longer than a month, the definition of what is being built may change or complexity and risk may increase. By limiting the maximum length of a Sprint, at most one month of development effort would be wasted, rather than several months in a classic waterfall project. Conversely, Sprints with a length of less than one week are possible, but should be executed only by a high-performance Scrum Team. Even with very short Sprints, the overhead of the inner events must be factored in, leaving even less time for actual software development. Teams working in ”micro sprints” like these need to be on their A-game every day. Ideally, the length of the Sprint does not change. If it must, it can only change in between Sprints, as a result of a decision made collaboratively during the prior Sprint’s retrospective meeting. Any change to the length of a Sprint will cause disruption to the Development Team’s cadence. This will correct over time, as will its Velocity.

Q8. You create a layered web application. The service layer includes a suite of nUnit tests for the code. The web application contains JavaScript and has no tests.

You need to include unit testing in the development and automated build of the application. You need to achieve this goal with the least amount of impact to the development team.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Configure the build to use the existing nUnit tests.
B. Create QUnit tests to test the Javascript in the web application.
C. Use Coded UI Tests to test the JavaScript in the web application.
D. Convert all the nUnit tests for the business logic layer into MSTests.
