Cisco Implementing Cisco Collaboration Hybrid and Cloud Technologies (CLHCT) v2.0 Sample Questions (Q112-Q117):

NEW QUESTION # 112
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: D

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.


NEW QUESTION # 113
A video device registered with Cisco UCM failed to make an outbound B2B call. From Expressway-C diagnostic logs, an engineer found that the destination pattern is
"john@example.com:5061", and the call was dropped with a 404 response code from Expressway-C. The search rule intended for this call-in Expressway-C is configured for Alias Pattern Match, Pattern type "Suffix," and Pattern "example.com". How must the configuration be changed to allow the call?

Answer: B


NEW QUESTION # 114
Refer to the exhibit. Which option addresses the warning message "This location main number might not be attended or active."?
