(Choose two.)

A. You can deploy Edge servers with multiple network interfaces or with a single network interface.
In both scenarios, you must enable NAT for the Internet-facing interface if you are using private Ip addresses.
B. Make sure that Expressway-Edge and Expressway-Core servers have their server certificates signed by the same certification authority and the CA certificate is uploaded to the trusted CA store otherwise the Traversal zone will not work.
C. Configure DNS SRV records according. Make sure that you can resolve DNS SRV record_collab-edge_tls.yourdomain.com outside your company network. Make sure that you cannot resolve it inside your company network.
D. Configure your firewalls to allow traffic from Expressway-Core to Expressway-Edge servers and to allow traffic from internet hosts to Expressway-Edge servers.
You do not need to configure firewall rules for traffic from Expressway-Edge to Expressway Core servers.

正解：B、C

解説：
Inside DNS SRV should be _cisco-uds._tcp.yourdomain.com with A record pointing to CallManager UDS service, could be running on TFTP server using 8443.
Outside DNS SRV should be _collab-edge._tls.yourdomain.com. TLS is required for external encryption pointing to A record of Expressway-E on port 8443.
Note: _cuplogin._tcp.yourdomain.com is NO longer needed, as Jabber gets Profile from Cisco CM.

A. Although a traversal client zone exists, there is no Unified Communications traversal client zone. One must be created.
B. Mobile and remote access login has not been enabled for the domain configured in the Expressway-C. The domain must be edited to allow Cisco UCM registrations.
C. SIP is disabled on the Expressway-E. The SIP protocol must be enabled on the server.
D. No Cisco UCM servers are configured in the Expressway-C. Servers must be added for CallManager and IM and Presence services.
