What port number is used for SNMP?

• A. 53
• B. 161
• C. 443
• D. 8080

Answer: (B)

The correct answer is 161 because this is the standard port number used for Simple Network Management Protocol (SNMP), which is a protocol used for network management and monitoring. SNMP operates primarily in the context of collecting and organizing information about managed devices on IP networks and is crucial for network administrators to monitor the performance and health of network devices. Port 161 is used for SNMP messages, enabling communication between SNMP managers and agents. This port allows the SNMP manager to query network devices for statistics, configuration data, and for management purposes, making it an essential component in network management systems. In contrast, the other choices represent different protocols: port 53 is used for Domain Name System (DNS) services, port 443 is utilized for HTTPS, providing secure web communications, and port 8080 is often used for web traffic or alternative HTTP services. Understanding these port assignments is important for managing and configuring network systems efficiently.
