HI,
I think the answer is a.

The rest would be valid in the case of CMR fields

Hi,

I'm sure about option D and if you are required to select only 1 option then D is the right one.

Hi Paresh,

I agree with ur answer.
But I've a doubt.
For CMR,I feel the option C is wrong.It cannot be a remote interface of another EJB?
Can anyone let me know this,Please?

HI Satheesh,
I agree with you as the specification mentions that the CMR field needs to have a Local interface.
However yesterday I tried with two beans with one being a CMR field of the other.And for the both the beans I had kept them as remote and I had no issues in deployment as well as in select operation.
I am not sure at what stage and in what form the rule of CMR fields having Local interfaces come in oepration.

Maybe someone can clarify on this matter
