Which two UDP services are available on an MCU? (Choose two.)

FTP uses TCP ports 20 and 21 for data transfer and control, as it requires reliable, connection-oriented delivery.

HTTP uses TCP port 80 because it depends on reliable, ordered delivery that TCP provides, not the connectionless UDP.

SNMP (Simple Network Management Protocol) uses UDP port 161 for device polling and UDP port 162 for trap notifications, making it a native UDP service on managed network infrastructure including MCUs. Its connectionless nature suits the lightweight polling model used for device management.

Encrypted SIP (SIP over TLS) operates over TCP port 5061 because TLS requires a reliable transport layer and cannot run over connectionless UDP.

H.323 gatekeeper communication relies on the RAS (Registration, Admission, and Status) channel, which operates over UDP port 1719. This UDP-based channel handles endpoint registration, call admission control, and bandwidth management between H.323 endpoints and the gatekeeper.
