Question

Which two functions does Cisco Expressway perform in the Collaboration Edge?

Choose two

A Expressway-C provides encryption for Mobile and Remote Access but not for business-to-business communications.
B Expressway-E provides a VPN entry point for Cisco IP phones with a Cisco AnyConnect client using authentication based on certificates.
C Expressway-E provides a perimeter network that separates the enterprise network from the Internet.
D The Expressway-C and Expressway-E pair can interconnect H.323-to-SIP calls for voice.
E The Expressway-C and Expressway-E pair can enable connectivity from the corporate network to the PSTN via a T1/E1 trunk.

Explanation

Expressway-E is the Internet-facing edge component, normally deployed in a DMZ/perimeter between the enterprise network and the Internet. An Expressway-C and Expressway-E deployment can also provide traversal for voice calls involving H.323 and SIP, including H.323-to-SIP interworking.
