Which action should you perform?
You create Microsoft Windows-based applications. You participate in the planning phase of an incident tracking tool for technical support analysts.
The incident tracking tool must meet the following requirements:
Technical support analysts must open multiple incidents simultaneously.
The application can run only one instance at a time.
Users must be able to adjust the order and layout of the incident screens.
You need to design an application user interface that meets these requirements with the minimum amount of code.

What should you do?
You are an enterprise application developer. You create a Web-based application. When the application executes, it creates large XML documents in memory. The end users report that the application performs slowly when manipulating large XML documents. You need to analyze the cause of the problem. What should you do?
What should you do?
You are developing a Web application. The Web application uses a GridView control to display data. You build your Web Forms for the Web application by dragging and dropping tables from the Data Connections tree in Server Explorer. You need to add a connection to your data by using the Add Connection dialog box as shown in the exhibit.
During the process, you need to configure the .NET Data Provider that you use to create the data source objects.

Which solution should you use?
You create Microsoft Windows-based applications. You are designing an application that will be deployed to employees in your company. The company requires that all internal applications are branded with the corporate logo and a copyright notice. You need to ensure that all forms in the application contain the appropriate branding and copyright notice. Your solution must be extensible, maintainable, and require minimum effort to lay out.

What should you conclude?
You are an enterprise application developer. An intermediate level programmer is preparing the request to place your distributed application into the production environment. According to corporate IT policies, you must specify the production server and network requirements to the production support personnel to review the application. Your application is a mission critical system. You are using three Microsoft Windows Server 2003 application servers that are clustered by using Microsoft Windows Network Load Balancing. The three application servers have the following network configurations:
AppSrv1
o IP Address: 172.30.103.40
o Subnet Mask: 255.255.255.0
o Default Gateway: 172.30.103.1
AppSrv2
o IP Address: 172.30.102.41
o Subnet Mask: 255.255.255.0
o Default Gateway: 172.30.102.1
AppSrv3
o IP Address: 172.30.102.42
o Subnet Mask: 255.255.255.0
o Default Gateway: 172.30.102.1
You need to validate the network settings for the three application servers, making corrections if necessary. What should you conclude?
What should you do?
You develop a Web application. Your application contains two settings in the Web.config file. You deploy your application to production. You need to modify the application settings in the production environment without manually editing the XML markup in the Web.config file.

What should you do?
You create Microsoft Windows-based applications. You design a composite user control that is used to enter e-mail addresses. The control is as shown in the following exhibit. (Click the Exhibit button.) The control validates the user input by using a regular expression. The control validates e-mail addresses and prevents the user from submitting blocked e-mail addresses. The control must permit the user to correct the entry if the user enters a blocked e-mail address. You need to provide feedback if the user enters a blocked e-mail address in the txtEmailAddress text box.
What should you do?
Which test should you perform?
You are an enterprise application developer. You create a routing application that ascertains the best routes for shipment of containers.
The application contains a complex routing method that examines the following parameters:
The weight of the containers
The length of the trailer that hauls the containers Road constraints such as weight limits and bridge heights
The method returns a list of roads to use. You need to design a unit test to ensure that the routes returned do not violate any known constraints. Which test should you perform?
What should you do?
You create Web-based client applications. You create a public function for your application that must connect to a data source. The public function must also perform a series of updates to the data. Some of the operations will result in exceptions if there are errors.
Your exception handling mechanism must meet the following requirements:
Callers of the function must be able to ascertain whether the function succeeded or failed. If the function failed, callers of the function must be able to find where and why it failed. If there is any error, the function must immediately stop processing.
You need to identify the best exception handling mechanism. What should you do?
What should you conclude?
You create Microsoft Windows-based applications. You are creating a component that will encapsulate a data source. Dozens of applications will use the component.
The component must meet the following design requirements:
1.The component must be able to be modified within a Rapid Application Development environment.
2.The component must be without a user interface.
You propose to derive the component from the System.Windows.Forms.Control class and to implement the IComponent interface. You need to decide whether the component will meet the requirements.
