210-065 Question #436: Real Exam Question with Answer & Explanation

The correct answer is A: Cisco TelePresence Management Suite. Enabling public internet third-party video systems to collaborate with internal CTS endpoints on CUCM requires TMS for endpoint management and scheduling, and Expressway-E for internet-facing B2B call traversal.

Question

An engineer wants to configure third-party video conferencing systems to collaborate with internal CTS endpoints that are registered to Cisco Unified Communications Manager. The third-party endpoints are located on the public Internet. Which two components are required for this design? (Choose two.)

Options

ACisco TelePresence Management Suite
BCisco Expressway Series with MRA
CExpressway-C
DCisco MXE 3500
EExpressway-E

Explanation

Enabling public internet third-party video systems to collaborate with internal CTS endpoints on CUCM requires TMS for endpoint management and scheduling, and Expressway-E for internet-facing B2B call traversal.

Common mistakes.

B. Expressway with MRA (Mobile Remote Access) is designed for Cisco Jabber and soft clients to register to CUCM from outside the network, not for B2B federation with third-party video conferencing systems.
C. Expressway-C is the internal-facing traversal component and alone does not provide the internet-facing B2B connectivity this design requires; it must be paired with Expressway-E to function.
D. The Cisco MXE 3500 is a media encoding and transcoding appliance used for video content preparation and publishing, not a signaling or traversal component for live video collaboration.

Concept tested. Cisco TMS and Expressway-E for B2B CTS interoperability
