Question 3

An administrator installs a new webserver (server1.example.com – 10.1.1.90) for storing Cisco Jabber update files to the network, but all Mobile and Remote Access registered clients still run the old Jabber software version, and the update fails. Which configuration task on an Expressway server solves the Jabber software update issue?

Options:

A.

Add a rule with the URL http://server1.example.com:80/ to the outbound HTTP allow list manually to allow pushing the new software to the clients.

B.

Add a rule with the URL http://server1.example.com:80/ to the inbound HTTP allow list manually to allow access to the new web server.

C.

Add a rule with the server IP address 10.1.1.90 in the URL to the inbound HTTP allow list because server names and FQDNs are not supported.

D.

Run an IM and Presence server discovery process on Expressway-C to add the new web server to the inbound HTTP allow list automatically.
