Networks: Ethernet, Switches

What do the status lights on the front of a 10/100 Ethernet switch indicate? (Select THREE.)

1. The connection speed of the connection
2. >>Which connections are in use by computers
3. Whether the connected computer is a server
4. >>Which protocol is in use on the network
5. >>Whether a connection is running full duplex or half duplex
6. Whether a printer is cabled to the network or not

Explanation : In a star network, all nodes on the network connect to a centralized hub or switch. Signal lights on the front of the hub or switch indicate which connections are in use by computers. Switches also indicate whether a full duplex connection is in use. Multispeed hubs and switches also indicate which connection speed is in use on each port.

There are no lights on switches that indicate which protocol is in use.

There are no lights on switches to distinguish the type of resource connected to that port. It is impossible to determine from status lights on a switch if the connected device is a server, printer, workstation, router or even another switch.
