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?
- A. SRV record _collab-edge._tls.example.com that resolves to ExpE.example.com on port 8443
- B. SRV record _collab-edge._tls.example.com that resolves ta 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 _cisco-uds._tcp.example.com that resolves to ExpE.example.com on port 5061
Answer: A
Explanation:
To allow external clients to discover the Expressway-E server, the administrator must configure the SRV record _collab-edge._tls.example.com that resolves to ExpE.example.com on port 8443.
This SRV record is used for Mobile and Remote Access to allow external clients to connect securely to the Expressway-E server. The _collab-edge._tls prefix is used to identify the service as a "collaboration edge" service and the .example.com suffix is the domain name for the organization. Port 8443 is the default port used for secure HTTPS connections to the Expressway-E server.

An engineer must configure the zone to connect to an Expressway-E using Single NIC with NAT.
The internal IP address is 192.168.10.63, and the NAT address is 203.0.113.5. What must the engineer configure on the Expressway-C to meet this requirement?
