In a Core-Distribution-Access Layer design, would you keep the Core L2 or
with high end L2/L3 switches such as the Cat6500 do you think it would be
better to do L3 in the core ?

It depends if you are after theoritical advice, or practical advice. I have
found it rare to have only L2 in the core (other than when using MPLS). The
focus of the exam is that the core should add minimum latency to forwarding
decisions, and thus the empahsis on why ACL's, VLAN aggregation etc,

It's best to always keep in mind where data jumps layers and then mentally
follow

Peter,
The current rumour for the Academy CCNP program is that Cisco is dropping
the 3 layer model and moving to a 2 layer model with L3 in the core for
the BCMS course. I guess I'll find out for certain at Networkers in
Orlando, Fla. this June.

Since at cisco's SJ Corp campus we run a L3 core, a L3 dist,
and a L2 access layer to the users.
