Single Answer
0You plug a 100 Mb/s hub into a switch. What is the expected outcome?
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
Hubs do not participate in IEEE negotiation, and therefore the speed will be detected. However, since duplex cannot be negotiated, 10 Mb/s and 100 Mb/s connections will be half-duplex and 1000 Mb/s connections will be full-duplex. Therefore the switch interface will be set to 100 Mb/s half-duplex.
