You are an enterprise application developer. You are reviewing an ASP.NET application that communicates with a Web service. The ASP.NET application experiences random performance issues. You plan to perform code profiling during a long-running load test. You need to define a code profiling strategy.
What should you do?

You are an enterprise application developer. You design an event logging mechanism for a serviced component. You need to ensure that the event logging mechanism conforms to the following requirements: All critical exceptions must be logged for debugging purposes.Administrators must be allowed to enable and disable tracing for different types of event logging.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are an enterprise application developer. You are creating a multilingual ASP.NET application. The development plan of the application specifies that the English version of the application must be released first, followed by the localized versions. You need to use a deployment mechanism for localization. You also need to ensure that the deployment mechanism requires the minimum amount of development and configuration efforts.
What should you do?

You are an enterprise application developer for a media organization. You create a Web service that provides large multimedia files to subscribers. The subscribers use a variety of client applications and browsers to access the content. You discover that during peak activity hours, multiple client applications simultaneously subscribe to the data. You need to ensure that the Web service meets the following requirements: It adheres to the WS-Security standards.It processes requests in a time-efficient manner.
What should you do?

You are an enterprise application developer. You plan to create an application that contains a user interface. The user interface calls the business layer Web Services Enhancements (WSE) Web service. You also plan to design an integration testing strategy for the application. You need to track and correlate the messages that are exchanged between the components by using the minimum amount of coding effort.
What should you do?

You work as the Microsoft.NET developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. The development and deployment of Extensible Markup Language (XML) Web Services forms part of your responsibilities at Domain.com.
The following exhibit illustrates a class definition in a Web service project:

public class MarketService
{
public Point ObtainMarket(string mobilePhoneNumber)
{
throw new SoapException(“Not implemented”, New XmlQualifiedName(“error”));
}
}

You have received instruction to configure the class in such a way so as to allow SOAP clients to invoke the ObtainMarket method.
What should you do?

You work as the Microsoft.NET developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. The development and deployment of Extensible Markup Language (XML) Web Services forms part of your responsibilities at Domain.com.
The following exhibit illustrates a class definition:

public class MarketService
{
internal string ObtainMarket(string mobilePhoneNumber)
{
return String.Empty;
}
}

You received instruction to modify this class so that it becomes a Web service, a Web service that will allow internal applications to invoke ObtainMarket as a Web method. You need to ensure that the Web method does not make use of session state and that it must make use of the default namespace.

What should you do?

You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the support and deployment of applications. You are currently developing an enterprise solution that consists of a Microsoft ASP.NET Web application and a Microsoft .NET Remoting component. The Web application connects to the .NET Remoting component via inter-process communication (IPC) channel. A Web server named Certkiller -WS01 will be used for the deployment of the enterprise solution. The following exhibit illustrates the production Web.config file configuration:

<configuration>
<system.web>
<customErrors mode=”RemoteOnly”/>
</system.web>
</configuration>
One requirement that should be kept in mind is that one should not be able to view specific error messages when accessing the Web application from the network or the Internet. Following is a list of the aspects included in the deployment design:
1. Deploy Microsoft Internet Security and Administration (ISA) Server to Certkiller -WS01.
2. Deploy the Web application to Certkiller -WS01.
3. Configure ISA server with a Web publishing rule to redirect requests to staging.fi-print.com to 127.0.0.1.

You now need to make a decision as to whether the design meets the requirements.

What conclusion can you draw?

You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the testing and stabilization of applications. You and the development team is currently busy developing an enterprise resource planning solution for Domain.com. The logical design for this application consists of a Microsoft ASP.NET Web application, a Microsoft .NET Remoting component, and a Microsoft Windows service. The Microsoft Windows service hosts the .NET Remoting component which is a marshal-by-reference component. The purpose of this component is to read and update the performance counters. The Web application is designed to access the component via Transmission Control Protocol (TCP) channel. The Web application is hosted on a Web server and the .NET Remoting component is hosted on an application server. A Developer named Mia Hamm has been instructed to perform the integration testing of the component. Following is the step-by step procedure that Mia Hamm followed during the integration testing:
1. Mia Hamm adds the component to an ASP.NET Web application project.
2. Mia Hamm does not configure Remoting in the Web application.
3. Mia Hamm accesses the Web application and invokes methods on the component.
4. The method calls fail.
You need to make a decision as to whether the test results can be considered valid.

What conclusion can you draw?

You work as the Enterprise application developer at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers in the domain run Windows Server 2003. Your responsibilities at Domain.com include the testing and stabilization of applications. Domain.com operates in the security and surveillance environment. You are currently developing a video surveillance application for Domain.com.
You perform a code review of the following class:

public class Camera
{
public Camera GetInstance()
{
return _null;
}
}

This class is supposed to make use of the Singleton design pattern to control access to a physical video camera. You need to modify the Camera class.
