On the Cisco VCS-E, what is the default port number for the H.323 connection on the local traversal zone between a Cisco VCS-C and VCS-4?
The correct answer is D. 6001. The default H.323 port used on the VCS-E for the local traversal zone connection to VCS-C is 6001, which is Cisco-specific and differs from standard H.323 ports.

Why each option
The default H.323 port used on the VCS-E for the local traversal zone connection to VCS-C is 6001, which is Cisco-specific and differs from standard H.323 ports.
Port 1719 is the standard H.323 RAS (Registration, Admission, and Status) port used for gatekeeper communication, not the VCS traversal zone H.323 port.
Port 1720 is the standard H.323 call signaling (Q.931) port used in typical H.323 deployments, not the Cisco VCS local traversal zone port.
Port 5060 is the standard SIP UDP/TCP signaling port and is unrelated to H.323 traversal zone configuration on the VCS.
Port 6001 is the Cisco-proprietary default port used for H.323 signaling on the VCS-E side of the local traversal zone between a VCS-C and VCS-E. Cisco VCS uses non-standard ports for traversal to distinguish traversal traffic from standard H.323 traffic, and 6001 is the defined default for this H.323 traversal connection.
