What should you do?
You are creating a Windows application by using the .NET Framework 3.5.
The application retrieves individual product details from a database within the network. The product
details frequently change.
The product details available to the application can be up to one hour old.
The details of a single product can be retrieved multiple times during a single execution of the application.
You need to design a caching strategy that uses the minimum amount of network bandwidth.

What should you do?
You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
You plan to add an existing .NET component into the current application. The .NET component has insufficient documentation.
The structure of the classes in the component must be analyzed before they are incorporated in the application.
You need to analyze the members in the component and the dependencies among them.

What should you do?
You are an enterprise application developer. You are reviewing the design of a component. The component is used to monitor an FTP folder on a Microsoft Windows 2003 Server computer.
You need to ensure that the component meets the following requirements: It is transaction-oriented.It copies data from files in the FTP folder.It runs without the intervention of the user. It requires the minimum amount of development effort.
What should you do?
Which two actions should you perform?
You create a Windows application by using the .NET Framework 3.5.
The application uses a Microsoft SQL Server 2008 database.
You discover that the application is non-responsive and performs slowly at certain times during the day.
Twenty-five additional users are added to the application to meet a deadline.
You need to ensure that all users experience a consistent level of high application performance
throughout the day. You want to achieve this goal by using minimum development effort.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
Which type of test should you use?
You create an ASP.NET application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
You are developing a test strategy for the application. The application must meet the following requirements:
– Render reports by using Microsoft SQL Server 2005 Reporting Services (SSRS).
– Support 750 concurrent users.
You need to identify a test strategy that ensures that the application meets the requirements.
Which type of test should you use?
Which code segment should you use?
You are an enterprise application developer. You are working on a component in an application that provides a business workflow solution. The component will be used as a workflow to manage purchase requisitions. You discover that a WebException is raised when you use the GetApprover private method to invoke a method of a Web Service.
You need identify a code that allows the component to invoke the following methods:
* The GetDefaultApprover method if a WebException is raised
* The ReportError method if any other exception is raised.
* The GoToNextStep method if no exception is raised.
Which code segment should you use?
What should you recommend?
You are creating a Windows application by using the .NET Framework 3.5.
You plan to evaluate the design strategy of the application.
The design strategy contains the following elements:
The application uses the ClickOnce deployment.
The application runs on computers that have the Microsoft Windows 98 operating system, a 256-MB RAM,
and a 1-GB disk space.
The application transmits the collected data to a server by using a Windows Communication Foundation
(WCF) service.
The application must meet the following requirements:
It displays real-time data.
It gathers data from a serial interface.
The code written for it is small and can be easily deployed.
You discover that the design strategy does not function properly.
You need to ensure that the design strategy functions appropriately.
What should you recommend?
What should you do?
You create an application by using Microsoft Visual Studio .NET 2008 and the .NET Framework 3.5.
The application will be used on personal computers and mobile-based devices. The current application design is composed of the following three layers:
– User interface layer
– Business layer
– Data access layer
You need to ensure that the application offers a custom experience to the end user based on the type of device used.
You also need to ensure that code duplication is avoided.
What should you do?
What should you do?
You are an enterprise application developer. You are reviewing the design of a component. The component is used to communicate with a legacy system. The component must meet the following requirements: It must handle high-latency network communications.It must accept synchronous calls from Windows and Web-based applications developed by using .NET Framework 2.0 in the local network.It must use asynchronous communications. You need to implement the design of the component.
What should you do?
Which proof of concept should you create?
You plan to create a Windows application by using the .NET Framework 3.5.
The Windows application must use a proprietary protocol to connect to a Windows Communication
Foundation (WCF) service. The application persists data to a Microsoft SQL Server 2008 database by
using the WCF service.
You need to analyze the feasibility of creating the application.
