Which port and protocol is used for SNMP traps for event notifications?

Explanation:
SNMP traps are event notifications sent by an SNMP agent to the network management system, and they travel over UDP to the trap listener. The standard destination port for these traps is 162, which is why UDP port 162 is the correct choice. Port 161 is used for normal SNMP queries from the manager to the agent, not for traps. Port 53 is the DNS port, and 158 isn’t a standard SNMP port.
