Which two functions are performed at the MAC sublayer of the OSI data link layer? (Choose two.)

• Adds Layer 2 control information to network protocol data.
• Places information in the frame that identifies which network layer protocol is being used for the frame.
• Controls the NIC responsible for sending and receiving data on the physical medium.
• Implements a trailer to detect transmission errors.
• Enables IPv4 and IPv6 to utilize the same network interface and media.

Case 2:

• Provides synchronization between source and target nodes.
• Integrates various physical technologies.
• Communicates between the networking software at the upper layers and the device hardware at the lower layers.
• Adds Layer 2 control information to network protocol data.
• Enables IPv4 and IPv6 to utilize the same network interface and media.
