Oracle Communications Session Border Controller — Question 17

Your Session Border Controller is configured as the source and destination for all signaling messages and media streams coming into and leaving the providers network.
Which two SIP functions does it provide? (Choose two.)

Answer options

• A. an IP edge router
• B. Back-to-Back User Agent (B2BUA)
• C. Edge proxy
• D. Data firewall
• E. Media gateway

Correct answer: B, D

Explanation

The correct answers are B and D because a Back-to-Back User Agent (B2BUA) facilitates handling calls by separating the two endpoints, while a Data firewall provides security for the signaling and media streams. Options A, C, and E are not correct as they do not directly represent the functions of a Session Border Controller in this context.
