What port numbers would a technician be looking for in the captured packets for SNMP traffic?

The correct port numbers that a technician would look for in captured packets for SNMP (Simple Network Management Protocol) traffic are 161 and 162.

Port 161 is used for SNMP operations, specifically for sending queries from a management system to a managed device, which is where monitoring begins. Port 162 is used for SNMP traps, which are automated alerts triggered by devices to notify the management system of issues or significant events, allowing for proactive management of the network.

When capturing network packets for analysis, identifying traffic on these ports indicates active SNMP communication, which is crucial for network device monitoring and management. The use of these specific ports is standardized for SNMP, aiding technicians in diagnosing issues related to network management effectively.

Other port numbers associated with different protocols, such as those listed in the other answer choices, do not pertain to SNMP and serve different purposes. For instance, ports 8080 and 443 are associated with HTTP and HTTPS traffic, respectively; 25 and 110 are used for email protocols like SMTP and POP3; while 53 and 67 pertain to DNS queries and DHCP. These distinctions highlight the importance of knowing specific port assignments for effective troubleshooting and network management.
