Oracle Communications Session Border Controller — Question 27

Which three statements are true about SIP, per RFC 326? (Choose three.)

Answer options

• A. SIP does not provide for resource reservation.
• B. SIP defines native methods for negotiating media streams.
• C. A SIP transaction occurs between a client and a server.
• D. To set up a voice session, SIP relies on protocols such as SDP and RTP.
• E. SIP signaling can only be used for voice over IP thereby limiting its use as a general signaling protocol.

Correct answer: C, D, E

Explanation

The correct statements are C, D, and E because a SIP transaction indeed occurs between a client and a server, and it uses protocols like SDP and RTP for voice sessions. However, statement A is incorrect as SIP does not provide resource reservation, and statement B is misleading since SIP does not define native methods for negotiating media streams; it relies on other protocols for that purpose.
