A host using a 10100 NIC is connected to a Catalyst switch T

A host using a 10/100 NIC is connected to a Catalyst switch. The switch interface is configured for autonegotiate, but the NIC is not. Assuming speed can be determined by the switch, which of the following will autonegotiation default to for this scenario?

A. 10 Mbps, half duplex

B. 10 Mbps, full duplex

C. 100 Mbps, half duplex

D. 100 Mbps, full duplex

Solution

C. 100 Mbps, half duplex

If speed is determined to be less than gigabit, then the switch always defaults to half duplex.
