Which Expressway node provides internal edge access to CUCM?

Which Expressway node provides internal edge access to CUCM?

• A. Expressway-C
• B. Expressway-E
• C. MRA
• D. CUCM

Answer: (A)

Expressway-C is the inside-edge component that directly interfaces with CUCM. It sits on the internal network near CUCM and forms the trusted edge with CUCM, enabling secure signaling and media paths for devices and applications that need access to CUCM services. Expressway-E lives in the DMZ and handles traversal for external traffic, while MRA describes the overall remote-access deployment that uses both Expressway-C and Expressway-E. So, the node that provides internal edge access to CUCM is Expressway-C.
