Question: 1 / 1055

Which port number is commonly used for the SNMP protocol?

69

161

The SNMP (Simple Network Management Protocol) primarily operates over UDP and uses port number 161 for its standard operations. SNMP is used for network management purposes, allowing the monitoring and management of devices in IP networks. This involves collecting information from devices such as routers, switches, servers, and more. The protocol allows network administrators to tune performance, find and solve network problems, and plan for growth.

Port number 69 is used for TFTP (Trivial File Transfer Protocol), port 80 is designated for HTTP (Hypertext Transfer Protocol), and port 25 is traditionally used for SMTP (Simple Mail Transfer Protocol). These ports serve different purposes and are not associated with network management tasks, which distinguishes port 161 as the appropriate choice for SNMP activities.
