Which WebSphere Exam Should I consider?

[Shalbha Jindal]

Hello All,
I am HIGHLY confused about which websphere certification should I consider. There are so many of them.
It would be great if someone could let me know the relative popularity and importance of the following websphere exams:
286
287
340
341
Also if there is any other exam which is more famous, please let me know.
Thank you
