Hi Mini,
Explaination : Local Client might have a remote component object, in that case it can see all the above methods and infact use it. In the question only the client is local not the component.
I think you are right. Although a remote interface can give out only remote component interface references and local home can give out only local component interfaces, I think local client can access a remote home without narrowing. So, I agree with you that all the options in the given question are correct.
Looking at the answer to this question, I can tell you that the question should rather look like the following -
"Which session bean
local component interface method(s) can be called successfully, by a local client?"
But not to worry, as far as I know the questions in the real exam are stated very clearly. So, you are not likely to face this type of problem in the real exam.
Anyway, If you dont mind me asking, when is your exam due?
Regards
Suman
