Briefly describe three options for analyzing switched networks.

What will be an ideal response?

Hubbing out: By placing a hub between a device of interest (such as a server) and the switch, and connecting the analyzer to the hub, you can view all traffic to and from the server.
Port redirection: Many switches can be configured to redirect (actually, to copy) the packets traveling through one port to another port. By placing your analyzer on the destination port, you can listen in on all the conversations that cross the network through the port of interest.
Remote Monitoring (RMON): Uses Simple Network Management Protocol (SNMP) to collect traffic data at a remote switch and send the data to a management device.
