MCNE zen question

Hi, after using Novell products (mainly NetWare) since 1992, and never
having certified (shame on me!), I now have been given incentive (or
rather, a directive!) to get CNE at least, and ideally MCNE, within 2
weeks! Wish me luck!

Looking at CNE and MCNE roadmap, MCNE contains ZfD as an elective... but
since I am going to have to do ZfD anyway as part of core CNE, I just
want to confirm that I then only need to do ONE of the MCNE electives?

In detail, my roadmap would be:
- exam 50-686, foundations of NW6.5
- exam 50-690, novell network admin NW6.5
- exam 50-691, advanced novell network admin NW6.5
- exam 50-692, desktop mgmt with Zen6.5
(CNE achieved!)

- CompTIA Project+
- exam 50-649, TCPIP for networking professionals
and since I am not a GW or BM person, and got ZfD in the CNE, ONE of:
- exam 50-663, integrating edir and AD
or
- exam 50-684, edir tools/diags
(MCNE achieved!)

Total 7 exams (4 to get CNE; 3 to get MCNE)

Thanks
Graham
