Which connections allow the use of full-duplex Ethernet?(Choose three.)

A.
switch to hub

B.
switch to host

C.
hub to hub

D.
switch to switch

E.
host to host

Explanation:
Full-duplex Ethernet uses two pairs of wires, instead of one wire pair like half duplex. And full
duplex uses a point-to-point connection between the transmitter of the transmitting device and the
receiver of the receiving device. This means that with full-duplex data transfer, you get a faster
data transfer compared to half duplex. And because the transmitted data is sent on a different set
of wires than the received data, no collisions will occur.
Full-duplex Ethernet can be used in three situations:
* With a connection from a switch to a host
* With a connection from a switch to a switch
* With a connection from a host to a host using a crossover cable
