Question 3
What it is the purpose of using ICE for Mobile and Remote Access endpoints in the Cisco Collaboration infrastructure?
  1. ICE controls the bandwidth usage for Cisco Collaboration endpoints if the endpoints are located outside the company network.
  2. ICE enables Cisco Collaboration endpoints to determine if there is direct connectivity between them.
  3. ICE uses FAST updates to optimize the video quality in case of packet loss. This technology is available only from Cisco Unified CM version 11.5 and later.
  4. ICE enablement allows for the Cisco Collaboration endpoint to register through Expressway servers to Cisco Unified Communications Manager behind a firewall. 
Correct answer: B
