Which data link sublayer controls the network interface through software drivers?

Which data link sublayer works with the upper layers to add application information for delivery of data to higher level protocols?

• MAC

• LLC

What is a function of the MAC sublayer? (Choose three.)

• controls access to the media

• checks for errors in received bits

• uses CSMA/CD or CSMA/CA to support Ethernet technology

• communicates between software at the upper layers and the device hardware at the lower layers

• allows multiple Layer 3 protocols to use the same network interface and media
