Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 122

What are two functions of Cisco Expressway in the Collaboration Edge? (Choose two.)

Answer options

• 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.

Correct answer: C, D

Explanation

The correct answers are C and D because Expressway-E does indeed create a perimeter network that separates the enterprise network from the Internet, while the combination of Expressway-C and Expressway-E enables interconnection between H.323 and SIP calls. Options A and B are incorrect as they do not accurately describe the functions of the Expressway in the context given, and E is not a primary function of the Expressway pair.
