Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 62

An engineer is deploying an Expressway solution for the SIP domain Cisco.com. Which SRV record should be configured in the public DNS to support inbound
B2B calls?

Answer options

• A. _collab-edge._tls.cisco.com
• B. _cisco-uds._tcp.cisco.com
• C. _sip._tcp.cisco.com
• D. _cuplogin._tcp.cisco.com

Correct answer: C

Explanation

The correct SRV record for supporting inbound B2B calls in the SIP domain is _sip._tcp.cisco.com, as it directs SIP traffic appropriately. The other options serve different purposes: _collab-edge._tls.cisco.com is for secure connections, _cisco-uds._tcp.cisco.com is used for Cisco Unified Domain Services, and _cuplogin._tcp.cisco.com is related to CUP services, none of which support the required inbound call functionality.
