I need further clarification, Can I take any of the one (1) 642 exams in order to re-certify my CCNP?
As long as it has not expired, yes.
Yes, any 642 Level exam will recertify your CCNP :)
CCNP, CCDP, CCIP, CCSP & CCVP certifications Complete one of the following recertification options:
Pass any 642 exam that is part of the professional level curriculum after 01/01/06
Pass any current CCIE or CCDE written exam.
Hope this helps!
