  21. The RemoteObject extends Object and implements (overrides) which methods?

  22. Say your RMI client has a reference to a remote object which extends UnicastRemoteObject. Then, the server for that object dies but is quickly restarted. If you were to invoke a method call on that object, what would happen?

  23. The following are implementations of Distributed Object Systems (DOS):

  24. In a Distributed Object System each call to a member function of a remore object instance is sent to the object server as a message containing (pick best):

  25. The codebase property value contains:

  27. In RMI, when can a remote interface extend a non-remote interface?

  28. The following code is (assume the ... are replaced by the appropiate code): 

    public interface Hello extends Remote { 
    String sayHello() throws RemoteException;
}

public class HelloImpl extends UnicastRemoteObject
	implements Hello {

	public HelloImpl() throws RemoteException { ...};
	public String sayHello() { ...	}
	private String sayGoodbye(){ ... };
}

  29. The primary goal of a Distributed Object System is to:

  30. Your boss asks you to build a system that will allow people on their workstations to do their heavy computing work on the supercomputer. You decide to use RMI and implement remote object. Your deployment will look like:

  42. If you run the following code: 

    class IFoo{
public:
  virtual int _stdcall GetFirst();
private:
  int m_nFirst;
};

///then, later, in main()

Ifoo * i = ...(get an object)
Ifoo * j = ...(get a different object)
    How many vptr and vtbl will be created for this code?

  43. In a MIDL file, an attribute is

  44. In MIDL, the attribute that tells us that this is a COM interface is

  45. The library keyword in a MIDL interface file tells the MIDL compiler to

  46. An in-process COM component knows that it is time to kill itself when

  47. COM components keep their own reference count by

  48. Say you generate a program that implements the MIDL function 

    
HRESULT foo([in,ref] wchar_t * a, [in,ref] wchar_t *b );
    and is then called be the client with: 
    p->foo(x,x);
    inside the function foo(), a and b are:

  49. The IDispatch interface in COM supports
