There is no experience reqirement for MCSE or MCSA althoug they say you should have X amount of exp for those test.... I got both those certs virtually with no exp. at all.

M$ has accepted some of Comptia certs as ELECTIVES for these certs, you still need to take the other core and elective requirements of the cert u follow. I did security+ as an elective for my MCSE:security (this is MCSE specialised in security). AFAIK, A+ and network+ combined will qualify as an elective for MCSE and MCSA.

MCSE requires 7 test.... 4 core, 1 elective form design and 2 any other elective

back to the topic.... security+ is a good test, it wasn't that hard for a n00b like me, covered bit of all security aspects, but not in depth.....

hope this helps......
