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.

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

• Enables IPv4 and IPv6 to utilize the same network interface and media.

• Places information in the frame that identifies which network layer protocol is being used for the frame.

• Integrates various physical technologies.

• Implements a process to delimit fields within a Layer 2 frame.

• Controls the NIC responsible for sending and receiving data on the physical medium.

What action will occur if a switch receives a frame with the destination MAC address FF:FF:FF:FF:FF:FF?

• The switch forwards it out all ports except the ingress port.

• The switch shares the MAC address table entry with any connected switches.

• The switch does not forward the frame.

• The switch sends the frame to a connected router because the destination MAC address is not local.

What action will occur if a switch receives a frame with the destination MAC address 01:00:5E:00:00:D9?

• The switch forwards it out all ports except the ingress port.

• The switch does not forward the frame.

• The switch sends the frame to a connected router because the destination MAC address is not local.

• The switch shares the MAC address table entry with any connected switches.

What action will occur if a host receives a frame with a destination MAC address of FF:FF:FF:FF:FF:FF?

• The host will process the frame.

• The host forwards the frame to the router.

• The host sends the frame to the switch to update the MAC address table.

• The host forwards the frame to all other hosts.
