When designing using the Cisco Enterprise Architecture, in which Enterprise Campus layer do the Enterprise Edge and Enterprise WAN modules establish their connection?
A.
Building Access
B.
Building Distribution
C.
Campus Core
D.
Enterprise Branch
E.
Enterprise Data Center
Explanation:
Some VCE give the answer as Building Distribution. Checking in the Cisco 640-863 Quick Reference Sheet, it is mentioned and illustrated as Campus Core. FYI.
The connection lines drawn in figure 2-5, on P48, corroborate campus core as the answer. My interpretation is that the Enterprise WAN module, inside the Enterprise Edge block, is the focus of the question.
(The wording of this question is not the greatest. Maybe it would be clearer to phrase it something like: In the Cisco Enterprise Architecture Model, to which layer does the Enterprise WAN module, of the Enterprise Edge Block, interface?)
Wording, take 2:
In the Cisco Enterprise Architecture Model, to which Enterprise Campus layer does the Enterprise WAN module, of the Enterprise Edge Block, interface?
Some of the confusions in the VCEs may be coming from what is read on page 42 of the cert book. It talks about some of the roles of the Distribution Layer and one of those roles can be to aggregate WAN connections.
