You've written all the UML diagrams you need for your companies online store. Other developers and architects have approved them. Now you are deciding which Enterprise Beans will use Container Managed Persistence (CMP) and which will use Bean Managed Persistence (BMP). When should you use BMP?


AWhen performance is essential and you are storing standard data types.
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.

Please help !!!

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

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
