Which two statements about Ethernet standards are true? (choose two)
A . Ethernet is defined by IEEE standard 802.2
B . Ethernet is defined by IEEE standard 802.3
C . Ethernet 10BASE-T dose not support full-duplex.
D . When an Ethernet network uses CSMA/CD, it terminates transmission as soon as collision occurs
E . When an Ethernet network uses CSMA/CA, it terminates transmission as soon as collision occurs

Answer: BD

Explanation:

http://www.ieee802.org/3/ CSMA/CD -It uses a carrier sensing scheme in which a transmitting station detects collisions by sensing transmissions from other stations while transmitting a frame. When this collision condition is detected, the station stops transmitting that frame.
