What is the end result if a 10/100/1000 IEEE 802.3u Gigabit Ethernet link has autonegotiation
enabled on the switch port and the host NIC is statically configured for 100 Mb/s and full-duplex?

What is the end result if a 10/100/1000 IEEE 802.3u Gigabit Ethernet link has autonegotiation
enabled on the switch port and the host NIC is statically configured for 100 Mb/s and full-duplex?

A.
The link comes up, because autonegotiation sets the switch port to 100Mb/s and full-duplex.

B.
The link does not come up because autonegotiation must be enabled or disabled on both sides
of the link.

C.
Autonegotiation sets the switch port to 100Mb/s and half-duplex.

D.
Autonegotiation sets the switch port to the defaults of 1000Mb/s and full-duplex.

E.
Autonegotiation sets the switch port to the defaults of 1000Mb/s and half-duplex.
