Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 16

An engineer must extend the corporate phone system to mobile users connecting through the internet with their own devices. One requirement is to keep that as simple as possible for end users. Which infrastructure element achieves these goals?

Answer options

Correct answer: B

Explanation

The correct choice is B, Cisco Expressway-C and Expressway-E, as they provide a secure and seamless way for mobile users to connect to the corporate phone system over the internet. Option A, Cisco Express Mobility, focuses on enhancing wireless connectivity but does not specifically address internet connections for mobile devices. Option C, Cisco Unified Border Element, is mainly for managing call sessions and may not simplify access for mobile users, while Option D, Cisco Unified Instant Messaging and Presence, is not relevant to extending telephony services.
