Frame flooding not configured with mac addresses or port security

ARP request MAC address of FFFF,FFFF,FFFF. ALL THREE switches flood the frame copy of the frame is forwarded to all active interfaces in VLAN 1

CD

Each switch port creates a separate collision domain Hubs do not separate collision or broadcast domains

A switch receives a frame whose source MAC address has not been seen by the switch since the switch was most recently powered on. What is the first thing a switch does in reaction to this frame?

It adds the source MAC address to its MAC table THEN it forwards the frame appropriately

Which of the following statements describes part of the process of how a switch decides to forward a frame destined for a known unicast MAC address?

It compares the unicast destination address to the bridging, or MAC address, table

Which of the following comparisons does a switch make when deciding whether a new MAC address should be added to its MAC address table

It compares the unicast source address to the bridging, or MAC address, or table

Which of the following statements best describes what a switch does with a frame destined for an unknown unicast address

It forwards out all interfaces in the same VLAN except for the incoming interface

Which of the following statements describes part of the process of how a LAN switch decides to forward a frame destined to forward a frame destined for a broadcast MAC address

It forwards the frame out all interfaces in the same VLAN except for the incoming interface

Bridges and switches help decrease Ethernet congestion by using which two of the following methods?

Separating collision domains increasing bandwidth

Standard Tree Protocol

Stops the flooding from continuing PREVENTS looping

Which of the following are reasons to create a VLAN?

To limit Broadcast Propagation New broadcast domain created. increases number of broadcast domains

Frame flooding If configured with MAC addresses

frame will not be forwarded to B because on the same switch Frame will be forwarded to next switch, but it recognizes the ping so only to that interface Frame forwarded to switch 3 and to all devices on there
