Which of the following will negotiate standoff timers to allow multiple devices to communicate on congested network segments?

A.
CSMA/CD

B.
OSPF

C.
DOCSIS

D.
BGP

Explanation:
Carrier Sense Multiple Access/Collision Detect (CSMA/CD) is used by devices in an Ethernet network for transmitting data on the network.

Any device on an Ethernet network can send data at any time. The network devices sense when the line is idle and therefore available for the transmission of data.
The network device then transmits a data frame onto the network. If another device sends a frame at exactly the same time, a collision occurs and the frames are
discarded. The network devices will then wait for a random period of time before attempting to send the frame again.
