You plug a 100 Mb/s hub into a switch. What is the expected outcome?

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.

B. 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.
