Which two UDP services are available on an MCU? (Choose two.)
The correct answer is C. H.323 gatekeeper E. encrypted SIP. MCUs expose specific UDP-based protocols for video conferencing signaling; H.323 gatekeeper and SIP both rely on UDP transport for their core functions.

Why each option
MCUs expose specific UDP-based protocols for video conferencing signaling; H.323 gatekeeper and SIP both rely on UDP transport for their core functions.
FTP relies on TCP ports 20 and 21 for reliable, connection-oriented file transfer and is not a UDP-based service.
SNMP is a network management protocol and is not among the primary UDP video conferencing services directly exposed by an MCU in this context.
H.323 gatekeeper uses UDP port 1719 for RAS (Registration, Admission, Status) messaging, making it a native UDP service on MCUs for endpoint registration and call admission control.
HTTP uses TCP port 80 for reliable web communication and does not operate over UDP.
SIP operates over UDP port 5060 by default for session signaling, and encrypted SIP variants also leverage UDP transport, establishing it as a primary UDP service available on MCUs.
