Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 76

Which two protocols are proxied over an Expressway-E/C pair when a MRA login including phone services is performed? (Choose two.)

Answer options

• A. SCCP
• B. HTTPS
• C. H.323
• D. SRTP
• E. SIP

Correct answer: B, E

Explanation

The correct answers are B and E because HTTPS is used for secure web communication and SIP is the signaling protocol for initiating and managing communication sessions. SCCP, H.323, and SRTP are not proxied in this context, as they serve different purposes in VoIP communication.
