Exam : Microsoft 70-549
Title : PRO:Design & Develop
10. You are an enterprise application developer. You are creating an application. Within your application, an order
contains order lines. Order lines are always contained within an order.
You need to analyze this structure and show the link between the order and the order line by using a class diagram.
Which diagram should you choose?
A.
B.
C.
D.
Answer: A
11. You are an enterprise application developer. You create a component that exposes a Shared method.
The Shared method performs a complex business algorithm and the method must support concurrent callers. You
use asynchronous processing to implement the method.
You need to ensure that the client application is notified about the completion of the method.
What should you do?
A. Add a Public Shared Event to the component and raise the event when processing is complete.
B. Pass a callback Delegate from the client application as a parameter to the processing method. Invoke the Delegate
when processing is complete.
C. Add a Public Shared Property to the component and permit the client application to poll the component for
completion.
D. Add a constructor that accepts a callback Delegate as parameter from the client application. Invoke the Delegate
when processing is complete.
Answer: B
12. You are an enterprise application developer. You are creating a component that processes loan requests. Your
component will be used inside Microsoft Windows Forms client applications.
The loan request form is complex and time consuming to complete. Loan data is saved to a Microsoft SQL Server
2005 database.
You need to ensure that in case of a system failure the loan officer does not need to re-enter any loan data.
What should you do?
A. Implement a Private Save method that saves all Property values to the database. Call the Save method from inside
your components finalizer.
B. Implement code inside the Set accessor for each Property that saves the Property value to the database.
C. Implement a Public Save method that saves all Property values to a Shared variable.
D. Implement code inside the Set accessor that saves the Property value to a Shared variable.
Answer: B
13. You are an enterprise application developer. You are creating a client/server application. You need to install the
application on the company network.
The client/server application must meet the following criteria:
The server component is a class library that is created by using the .NET Framework.
The client component is a Microsoft Windows-based application that is created by using the .NET Framework.
The client component and the server component must communicate by using a binary protocol.
The fewest possible ports are opened between the client component and the server component.
You need to identify a technology that permits the server to communicate with the client component through the
TCP/IP protocol.
Which technology should you use?
A. Message Queuing
B. .NET Remoting
C. Web services
D. DCOM
Answer: B
14. You are an enterprise application developer. You are implementing a new component for an application. The
component accesses a database to populate a list of customer objects and exposes a method that is named
GetAllCustomers.
The component uses a design pattern to access the database only on an as-needed basis. A caching mechanism
exists in a lower tier of the application architecture. The component must not cache data.
You need to implement the logic for populating a list of customer objects by using a database query. You also need
to ensure that you meet the company guidelines for the component design pattern.
What should you do?
A. Execute a query in the constructor of the component to populate a field of type List(Of Customer). Return the List
reference in the call to the GetAllCustomers method.
B. Execute a query in the static constructor of the component to populate a static field of type List(Of Customer).
Return the List reference in the call to the GetAllCustomers method.
C. Execute a query in the GetAllCustomers method to populate a local variable of type List(Of Customer). Return the
List reference.
D. Execute a query in the GetAllCustomers method to populate a field of type List(Of Customer) only if the field is
null. Return the List reference.
Answer: C
15. You are an enterprise application developer. You are creating an application that will track shipments.
This application must support integration with applications that run on different platforms and operating systems. The
application that you are creating can be invoked only through SOAP messages over HTTP.
You choose Web services instead of .NET Remoting to meet these requirements.
You need to specify the reason for choosing Web services.
Which statement should influence your decision?
A. SOAP messages cannot be exchanged in .NET Remoting.
B. Web Services Description Language documents cannot be generated from .NET Remoting class definitions.
C. .NET Remoting objects will not be interoperable with other platforms.
D. .NET Remoting objects cannot be invoked through HTTP.
Answer: C
