What do ports 161/162 primarily communicate with in a network?

Ports 161 and 162 primarily facilitate communication through the Simple Network Management Protocol (SNMP). Port 161 is used for sending requests and receiving responses from SNMP agents on network devices, such as routers and switches, which allows for monitoring and management of these devices. Port 162 is utilized for receiving SNMP trap messages, which are alerts or notifications sent from the monitored devices to the management system.

This protocol plays a crucial role in network management, enabling administrators to oversee the health and status of network components, making it essential for effective network administration. The other options do not accurately represent the function of these ports: DHCP (Dynamic Host Configuration Protocol) operates on a different port and is used for IP address configuration; firewalls involve different configuration protocols; and file transfers typically use protocols like FTP, SFTP, or HTTP, not SNMP.
