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 client applications forms part of your responsibilities at Domain.com. You implemented a strong-named managed assembly that makes use of Enterprise Services. The assembly is not registered for use within a COM+ context. And no RunInstaller attributes have been applied to any of the classes in the assembly. You have been instructed to register the assembly with COM+ to accommodate the COM clients.

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 client applications forms part of your responsibilities at Domain.com. The exhibit below illustrates the currently existing class definition:

public class PropertyManager : ServicesComponent
{
public void MoveInNewCustomer(Customer customer, Unit unit) {
}
}

Client applications call the MoveInNewCustomer method to move a new customer into a unit. You have been instructed to ensure that this process occurs within the context of a transaction. If a transaction does not already exist when this method is called, a transaction should be created. Exclusively in the event of an exception being thrown you want the transaction to abort.

To this end you need to modify the class to meet these requirements. What should you do? (Choose the correct code segment.)

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. Domain.com operates as an Internet Auctioneer. The development and deployment of Microsoft.NET Remoting components forms part of your responsibilities at Domain.com. You have been instructed to develop an OrderProcessor class that is responsible for charging a customer’s credit card, notifying the shipping department of the particular product that must be shipped, as well as updating the product inventory database. A COM+ application will be hosting the OrderProcessor class. To this end you need to create the class definition.

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 Client applications forms part of your responsibilities at Domain.com. You are currently developing a Microsoft Windows Forms client application that will retrieve data from an Extensible Markup Language (XML) Web Service. This XML Web Services requires Kerberos authentication. To this end you use the Web Services Enhancements (WSE) 3.0 proxy generation tool (wsewsdl3.exe) to generate a proxy to the Web service. You then create a policy file named policies.config. Policies.config specifies the authentication requirements.

You now need to specify the policy file in the app.config file What should you do? (Choose the correct configuration.)

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 Client applications forms part of your responsibilities at Domain.com. You are currently developing a client application that will retrieve data from two Extensible Markup Language (XML) Web Services.
1. The one Web service requires the use of username/password authentication.
2. The other Web service requires the use of Kerberos authentication. You make use of the Web Services Enhancements (WSE) 3.0 proxy generation tool (wsewsdl3.exe) to generate the proxies to the two Web services that requires the different authentications. To this end you create a policy file that specifies the authentication requirements. Now you need to ensure that the requirements are enforces when you call each of the Web services.

What should you do? (Each correct answer presents part of the solution. Choose two.)

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 implementation of policies for Web applications forms part of your responsibilities. You deployed a Microsoft Web Services Enhancements (WSE) 3.0-enabled Web service application to a production server. Each Web service that is implemented in the application has a Policy attribute applied. This attribute specifies the name of a policy in a policy file. The production server has the Microsoft.NET Framework 2.0 installed, but not Microsoft Visual Studio 2005. You are required to modify the Web service on the production server to use a different set of policies than those that were used during the development.

What should you do?

You are an enterprise application developer. You are developing an application that runs in an N- tier environment. You need to design your N-tier layers to enforce client-based certificate security.

How should you complete the diagram? (To answer, drag the appropriate layers to the correct locations in the answer area.)

You are an enterprise application developer. You design an application that communicates with other applications through .NET Remoting. The application has a large DataSet. You need to improve the performance of the application.
What should you do?

You are an enterprise application developer. You develop a solution by using Microsoft Visual Studio .NET 2005 and .NET Framework 2.0. The application will be used to receive and process sales orders. The application is designed as a three-tiered application. The logical design of the application identifies the following services:
* Update the ship date on an order.
* Verify sales quantity on an order.
* Store sales order information.Display product information.
* Display order details.

The security policy has the following specifications:
* Changes to the database must be handled through stored procedures.
* Other services must be handled in other layers.
*
You need to identify the services that must be placed into the stored procedures.
Which two services should you choose? (Each correct answer presents part of the solution. Choose two.)

You are an enterprise application developer. You plan to review the design of a component. The component is used to process purchase orders from distributors. You need to ensure that the component meets the following requirements:
* It is highly available.
* It is transaction-oriented.
* It is accessible over the company intranet.
* It requires the minimum amount of coding effort.
