Single Answer
0You have auto-negotiation turned off on the node, but it is turned on at the switch's interface connecting the node. The interface is a 10/100/1000 Mb/s interface and the node is 100 Mb/s full-duplex. What will the outcome be when you plug in the node?
Answer Options
A
The switch interface will be set to the 100 Mb/s full-duplex.
B
The switch interface will be set to the 100 Mb/s half-duplex.
C
The switch interface will be set to the 10 Mb/s full-duplex.
D
The switch interface will be set to the 10 Mb/s half-duplex.
Correct Answer: B
Explanation
Cisco switches can auto-detect speed, so the speed sensed will be 100 Mb/s. However, if the switch cannot detect the speed, then it will fall back to 10 Mb/s. Duplex is decided upon by bandwidth when IEEE auto-negotiation is turned off. If the speed is 10 Mb/s or 100 Mb/s, then the duplex will be half-duplex; otherwise it will be full-duplex on 1000 Mb/s links.
