An ISDN gateway is registered to Expressway-C with a prefix of 9 and/or it has a neighbor zone specified that routes calls starting with a 9.
Which value should be entered into the "Source" field to prevent toll fraud regardless at origin of the call?

Answer: B


NEW QUESTION # 262
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: C

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.
