Thanks Priscilla

I do have your book and have read most of it your be glad to hear.  The test
is hard i have sat it once already i got a 806 needed a 825 its the time
which kills you you have to do 75 questions in 90 minutes.  Without breaking
the nda there were quite a few long questions like this which stumped me.  I
thought i would walk it with already having my ccnp and enough experience it
just goes to show.

Thanks

Stephen
