Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 122

An administrator must configure the DNS SRV records for Mobile and Remote Access for a company with the domain example.com, the Expressway-E FQDN is ExpE.example.com, and the Expressway-C FQDN is Exp-C.example.com. What must the administrator configure to allow external clients to discover the Expressway-E server?

Answer options

• A. SRV record _collab-edge._tls.example.com that resolves to ExpE.example.com on port 8443
• B. SRV record _cisco-uds._tcp.example.com that resolves to ExpE.example.com on port 5061
• C. SRV record _cisco-uds._tcp.example.com that resolves to ExpC.example.com on port 8443
• D. SRV record _collab-edge._tls.example.com that resolves ta ExpE.example.com on port 5061

Correct answer: A

Explanation

The correct answer is A because the SRV record _collab-edge._tls.example.com on port 8443 is specifically needed for external clients to discover the Expressway-E server. Options B and C are incorrect as they reference the wrong SRV record types and ports. Option D contains a typographical error ('ta' instead of 'to') and also points to an incorrect port for the Expressway-E server.
