What are two ways that the carrier-sense multiple access with collision detection (CSMA/CD) MAC protocol help devices "talk" with each other in an Ethernet network? (Choose two.)

The correct answer is A. It allows an Ethernet device to check to see if anything else is transmitting before trying to send. B. It allows a network device to either transmit data or receive data. CSMA/CD allows an Ethernet device to check if the network is idle (carrier sense) before attempting to transmit, reducing the chance of collisions. With CSMA/CD, a device can either transmit or receive data at a given time (half-duplex), not both simultaneously, which helps…

Question

What are two ways that the carrier-sense multiple access with collision detection (CSMA/CD) MAC protocol help devices “talk” with each other in an Ethernet network? (Choose two.)

Options

AIt allows an Ethernet device to check to see if anything else is transmitting before trying to send.
BIt allows a network device to either transmit data or receive data.
CIt operates in half-duplex or full-duplex mode.
DIt allows a network device to transmit and receive data simultaneously.

Explanation

CSMA/CD allows an Ethernet device to check if the network is idle (carrier sense) before attempting to transmit, reducing the chance of collisions. With CSMA/CD, a device can either transmit or receive data at a given time (half-duplex), not both simultaneously, which helps coordinate communication and manage collisions.
