Which technology is used to secure signaling for Webex MRA?

• A. UDP
• B. TLS
• C. ICMP
• D. FTP

Answer: (D)

TLS is used to secure signaling for Webex MRA. Signaling carries the control messages that establish and manage the session, and securing it with TLS provides encryption, authentication, and integrity for those messages. This typically means SIP signaling runs over TLS (SIPS) or another TLS-based channel, which sits atop TCP to ensure reliable delivery. UDP doesn’t offer encryption or reliability for signaling, ICMP is a network diagnostic protocol not used for signaling, and FTP is for file transfer, not signaling. So TLS is the right choice to protect the signaling path in Webex MRA.
