5. Which data link sublayer controls the network interface through software drivers?
- MAC

6. Which data link sublayer works with the upper layers to add application information for delivery of data to higher level protocols?
- MAC
- LLC
7. 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
