Future MSCA test taker..

Hello guys! I am certified A+/ Network+. I've heard that anybody who has A+ and Network+ can pursue to MSCA? Please correct me if I'm wrong. Can someone tell me what exams should I take? Also, should I choose Windows200? or 2003? Please advise. Thank you!

If you use the CompTIA certs for your elective, then you only have to take the two server OS tests and one client OS test. Otherwise, you have to take an elective test.
Opinions may differ, but I would recommend the 2003 track, with XP as your client OS. If you know Server 2003, it would not be too hard to apply that knowledge in a 2000 environment.
Good luck!
