Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 20

What it is the purpose of using ICE for Mobile and Remote Access endpoints in the Cisco Collaboration infrastructure?

Answer options

• A. ICE controls the bandwidth usage for Cisco Collaboration endpoints if the endpoints are located outside the company network.
• B. ICE enables Cisco Collaboration endpoints to determine if there is direct connectivity between them.
• C. 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.
• D. ICE enablement allows for the Cisco Collaboration endpoint to register through Expressway servers to Cisco Unified Communications Manager behind a firewall.

Correct answer: B

Explanation

The correct answer is B because ICE facilitates the assessment of direct connectivity between endpoints, which is crucial for optimizing communication. Option A misrepresents ICE's role, which is not primarily about bandwidth control. Option C discusses a feature that, while related, does not directly address ICE's main function in connectivity. Option D incorrectly describes the registration process as being the primary purpose of ICE.
