List the two main reasons for adding a VLAN tag to an Ethernet frame

Limit broadcast domainsPrioritize traffic flows

241

This type of address is used only by the Data Link Layer

MAC (Media Access Control)

242

This duplex mode is used when devices on a network share a communication channel. Device can send or receive data but NOT at the same time.

Half-Duplex

These frames are intended for a single device on the network. The destination address is the address assigned to the receiving device.

Unicast Frames

246

These frames allow frames to be sent to a specific group of devices on the network. The destination address is a multicast address assigned by a higher level protocol or application.

Multicast Frames

247

These frames allow frames to be sent to all NEs in the same broadcast domain.  The destination address for broadcast messages is always ff:ff:ff:ff:ff:ff, which is 48 bits, all 1s, in binary notation.

MAC address tables correlate sender MAC addresses with___.
