A + B
“More generally, a zone is a collection of endpoints that share the same dialing behavior and bandwidth settings. Zones can be local to the VCS or remote.”
As far as I know, there is nothing in the VCS referred to as “Addressing Zones”. There are Zones and Subzones. Zones are used to point to peer devices on the network, such as other VCSs, CUCMs, DNS servers, and Expressways. They are not referred to anywhere as local or remote and this is a vague concept as it relates to the the VCS. Answer B describes a subzone, not a zone. Answer C is technically correct, but within the VCS the terms traversal and non-traversal typically refer to whether a call is being transcoded (SIP to H.323 or vice versa). There is a Traversal Client zone on the VCS-C (or Expressway Core) and both Traversal Client and Traversal Server Zones on the VCS-E (Or Expressway Edge) But there is nothing called a non-traversal zone – only zones that stay inside the network and zones that direct through the firewall. Answer D seems more correct to me than A because all zones are configured locally on the VCS and there is something called a Local Zone as well. E is incorrect because a DNS zone is a zone, and not a subzone. Subzones are totally different.
I feel A and C are the answers.
Traversal and nontraversal relate only to subzone.
