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 creating a message queue programmatically. This message queue will be accessed by two applications. Each message represents an instance of a public class named OrderInfo. The OrderInfo class does not derive from ServicedComponent, and it does not implement any interfaces. You need to ensure that the state of the class is preserved when a message is sent to and received from the message queue. This state of the class would include the values of private members. The message receiving application understands only the basic .NET Framework classes, and the OrderInfo class. To this end you need to specify the formatter that will be used to serialize and deserialize messages.

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. You have received instruction to develop and order fulfillment application. This order fulfillment application must send multiple messages to the queue in the case of it receiving an order. After the application sends the messages to the queue, it must update an inventory database accordingly. In the event of an error occurring for one of the messages while it is busy updating the database, the application must automatically remove all messages that were sent for the current order. In the event of the database update being successful, another application on the same computer must read and process the messages. Only these two applications must be allowed to access the messages.
Now you need to create the message queue manually.

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 have received instruction to create an instance of the PropertyManager class from a client application. Following are the circumstances that you need to keep in mind in your attempts to accomplish the task at hand:
1. A class named PropertyManager exists in an assembly named PropertyManagement.dll.
2. The class and component are registered with COM+ services.
3. The COM+ application that hosts this class id configured as a server application. 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. The development and deployment of client applications forms part of your responsibilities at Domain.com. You have developed a serviced component that will be used by both managed and unmanaged applications within Domain.com. A remote computer will be hosting this serviced component. The serviced component will be accessible through DCOM. The computers that host the client applications have the .NET Framework 2.0 installed. You have received instruction to allow both managed and unmanaged client applications to reference the serviced component.

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.

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.

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.
