You are designing updates to an existing Windows Presentation Foundation (WPF)
application that connects to a Microsoft SQL Server 2008 database. The application
updates will require updates to the database. You have the following requirements: Prevent
data loss. Recover the database if the database update fails. You need to recommend a
database deployment strategy. Which two actions should you recommend? (Each correct
answer presents part of the solution. Choose two.)

You are designing a .NET Framework 4 solution that contains a Windows Presentation
Foundation (WPF) application and a Windows Communication Framework (WCF) Web
service. The WPF application will be deployed to users’ desktops located in the company’s
corporate network. The WCF Web service will be deployed to a Web farm located in the
company’s perimeter network. The firewall between the perimeter network and the Internet
allows only HTTP and HTTPS traffic. You need to recommend an approach for minimizing
the attack surface of the WCF Web service. What should you recommend?

You are preparing to deploy a solution that includes a Windows Forms application and
several COM components. Unsigned interop assemblies have been created for each of the
COM components. You need to recommend an approach for deploying the solution. What
should you recommend?

You are designing a multi-tenant Windows Presentation Foundation (WPF) application that
will connect to a Microsoft SQL Server 2008 database. The WPF application will change the
structure of database tables and views at runtime based on the tenant’s configuration. The
WPF application must meet the following requirements: Keep each tenant’s data separate.
Allow changes to the structure of the tables and views for each tenant without interfering
with other tenants’ data. You need to recommend an approach for managing the database
structure. What should you recommend?

You are designing a Windows Presentation Foundation (WPF) application that accesses a
business tier. The business tier is implemented as a Windows Communication Foundation
(WCF) service and stores data in a Microsoft SQL Server 2008 database. The WCF service
will be accessed by external applications that do not use the .NET Framework. You need to
recommend an approach for passing data between layers. What should you recommend?

You are designing a Windows Presentation Foundation (WPF) application. The WPF
application must run against either Microsoft SQL Server 2008 or a third-party database
system without duplicating data access logic. You need to recommend a data access
technology. What should you recommend?

You are designing a .NET Framework 4 solution that contains a Windows Presentation
Foundation (WPF) application. The WPF application includes CPU-intensive calculations.
The calculations can be run on a separate process and can effectively be isolated from the
rest of the WPF application. You need to recommend a deployment strategy that maximizes
the scalability of the calculations for each user. What should you recommend?

You are designing a .NET Framework 4 solution that includes a Windows Presentation
Foundation (WPF) application, a Windows service, and a private assembly shared by the
WPF application and by the Windows service. The solution stores data in a local Microsoft
SQL Server Compact 3.5 database. The WPF application and Windows service will each
access the database directly. The solution will be installed by using Windows Installer. You
have the following requirements: • The installer must allow users to specify the installation
folders for the WPF application and for the database. • The solution must support the
deployment of updates to the WPF application without restarting the Windows service. You
need to recommend an approach for installing the solution. Which two actions should you
recommend? (Each correct answer presents part of the solution. Choose two.)

You are designing an n-tier .NET Framework 4 solution that includes a Windows
Presentation Foundation (WPF) application and a Windows Workflow Foundation (WF)
component. The WF component contains functionality to incorporate frequently changing
rules. You need to recommend a tier for the deployment of the WF component that will not
degrade the performance of the WPF application. Which tier should you recommend?

You are designing a Windows Presentation Foundation (WPF) application that uses .NET
Framework 4. The WPF application will be deployed to 5,000 users worldwide. You need to
recommend an approach for identifying problems that users will experience. Which testing
methodology should you recommend?
