A mock exam question

Hi all,
Here is a mock exam question:
What is true about BMP?
(A) Improves your ability to move your EJB from one App server to another.
(B) Reduces your ability to move your EJB from one App server to another.
Answer is B
I wonder why?
Thanks,
Tom

This question is poorly worded and very indicative to the quality of questions most mock exams ask. I have yet to see a mock exam that comes anywhere close to the type of questions asked on the actual exam. That is not to say the mocks are easier or harder, just different. Full Disclosure: I have not tried the WhizLabs Exam.
Back to the question: "What is true about BMP?" We are given only two choices:
(A) Improves your ability to move your EJB from one App server to another.
Improves portability compared to what? To CMP? Sure, without a doubt BMP is easier to port than CMP.
(B) Reduces your ability to move your EJB from one App server to another.
Reduces portability compared to what? To not using ejbs at all? In that case I would have to agree given the choices.
With nothing to compare BMP with, it is impossible to give a reasonable answer to this question. Don't worry, the questions on the actual exam are not nearly as vague.
If you are keeping score at home then I would mark both answers as correct.

I always agree with Chris Mathews.
I believe BMP has evolved in the aging of the EJB specification: 1.0 - 1.1 - 2.0.
Correct me if I'm wrong, but I believe you are
taking an old mock exam.
