Genesys Cloud CX Professional — Question 126

Which protocol is used to transport digitized audio?

Answer options

• A. TLS
• B. TCP
• C. RTP over UDP
• D. SIP over UDP

Correct answer: C

Explanation

The correct answer is C, as RTP over UDP is specifically designed for real-time audio and video streaming. Option A, TLS, is a security protocol that encrypts data rather than transporting audio, while TCP (Option B) is a connection-oriented protocol that is not optimized for real-time audio delivery. SIP over UDP (Option D) is used for initiating and managing communication sessions but does not transport the audio itself.
