Which protocol and port does NTP use for time synchronization by default?
Explanation:
The Network Time Protocol (NTP) uses UDP port 123 for time synchronization. Network Management Protocol (SNMP) uses TCP/161 to listen for incoming SNMP messages. TCP/123 can be configured for NTP, but it is normally not used by default. UDP/69 is used by Trivial File Transfer (TFTP) for file transfers.
