BWhen performance is not essential and you are storing standard data types.
CWhen performance is essential and you are storing complex data types.
DWhen performance is not essential and you are storing complex data types.

guys a question related to this one.

in the real part-1 exam, the multiple choice exam do they mention how many you need to choose or they are open ended.

i mean if a question has 2 right answers and 5 options provided to choose. Do they explicity say (choose 2).

please clarify

[Devendra Dave]

I checked the site nothing is mentioned stating more than on answers is correct or not. Also solution description is contradicting. It says first correct answers are A, C and D but in solution description itself it says that choice C is incorrect. Please check this statement.
"Choice C is incorrect because using Container Managed Persistence will increase the portability of the Enterprise Bean and should be used wherever possible."

Could any one provide me the correct answers for this questions
I may be wrong.

Thanks & Regards
Dave
