A.An end-station connected to a hub will always be half-duplex.

B.Ethernet switches only support half-duplex transmission.

C.All of the above.

D.Half-duplex transmission is less efficient because the frame MTU is smaller.

A.The Data Link Layer is responsible for encapsulating the packet into a frame for transmission on the transmission media.

B.The Data Link Layer is responsible for encapsulating the packet into an IP header and routing the packet.

C.The Data Link Layer is responsible for timing of the signals on the transmission media

D.The Data Link Layer is responsible for formatting the packet for applications such as JPEG format.

A.A regional Internet registry

C.Small optical module available in a variety of formats.

D.Contains the CPU that runs the routing protocol software as well as the switch fabric.

A.A device that receives a signal and based on the Layer 2 destination address, makes a decision on which ports the signal should be retransmitted.

B.A device that receives a signal and based on the Layer 3 destination address, makes a decision on which ports the signal should be retransmitted.

C.A passive device simply used to connect two or more cables. Does not generate or amplify any signals.

D.A device that receives and retransmits a signal out its other ports, but does not do any Layer 2 analysis of the data.
