Q6: A computer’s NIC is hardcoded to 1000 Mbps and full-duplex, and it is connected to a switch whose Fast Ethernet interface is set to autonegotiate speed and duplex. What speed and duplex will the switch use if the autonegotiation on the computer’s NIC is deactivated as a result of hardcoding the speed and duplex?
a. 100 Mbps and full-duplex
b. 100 Mbps and half-duplex
c. 1000 Mbps and full-duplex
d. 1000 Mbps and half-duplex
e. The link will be inactive.
