Bert's question #3.3 -- please explain!

[Seid Myadiyev]

Can somebody please explain step by step how to go about this type of questions?
--------------------------------------------------------------------------------
3.3 For this drag and drop type question, you can use each element only once. Which interface should be matched with which fact, so that all four matches are correct?

1. remote component --- a. does not have a getHomeHandle() method
2. remote home --- b. extends 'javax.ejb.EJBObject'
3. local component --- c. methods must NOT throw 'java.rmi.RemoteException'
4. local home --- d. can be used to retrieve an EJBObject reference.
1 - b
2 - d
3 - a
4 - c
--------------------------------------------------------------------------------
For example: what does answer 4-C mean?

My answers are:
1 - ABD
2 - none
3 - AC
4 - AC
but "...each element only once...".
Please clarify!

Seid, if you match numbers with letters you will get a statement which is true, e.g.:
(4) local home (c) methods must NOT throw java.rmi.RemoteException
the same for the rest. You can use each item only once. Other combinations do not claim a TRUE statement.
On exam you will not be confused by such problems as you will 'consume' an item once put in a slot, hence you will not be able to put it in multiple places if the question suggests the opposite.
