Implementing Cisco Collaboration Cloud and Edge Infrastructure (CLCEI) — Question 175

What is a capability of Interactive Connectivity Establishment passthrough in Cisco Expressway?

Answer options

• A. It enables media path optimization between endpoints by leveraging a TURN relay.
• B. It allows direct SIP communication between Mobile and Remote Access registered endpoints without passing through Expressway.
• C. It enables the integration of Cisco UCM call services and Cisco Webex Cloud.
• D. It allows media between Mobile and Remote Access registered endpoints through Expressway.

Correct answer: D

Explanation

The correct answer is D because it specifically describes how Expressway facilitates media between Mobile and Remote Access endpoints. Option A is incorrect as it refers to media path optimization which is not the primary function of the passthrough feature. Option B is wrong since it suggests that communication bypasses Expressway entirely, which contradicts the passthrough concept. Option C is unrelated to the passthrough functionality and focuses on integration instead.
