| Hello, I am in the Cisco Academy and I am having trouble with a few questions on switching I was wondering if anybody can help me out.
1. What networking technologies will switching improve?
2. How does am Ethernet Bridge handle an incoming frame? 3 ways
3. Where are the switching tables stored in a Cisco LAN switch.?
4. What is an example of a Layer 2 Broadcast address?
5. Why does a switch have a higher throughput compared to a bridge? Thanks | |

1. What networking technologies will switching improve?
hmmm .. ethernet ?
2. How does am Ethernet Bridge handle an incoming frame? 3 ways
forward, filter or flood
3. Where are the switching tables stored in a Cisco LAN switch.?
cam table
4. What is an example of a Layer 2 Broadcast address?
ffff.ffff.ffff
5. Why does a switch have a higher throughput compared to a bridge? Thanks
by segmenting collision domains to the switchport, unlike a hub. | |

| Take it with a grain of salt, I've been out of the field for almost two year now...
1. No clue. 
2. That'd be:
- nothing (bridge knows of destination, and it's on the same port)
- forward to another port (bridge knows of destination, and it's on a diferent port)
- forward to all other ports (bridge doesn't know of destination)
3. I don't remember this one.
4. For ethernet that would be 48 '1' bits.
5. Because it switches in hardware (bridges switch in software).

| Thanks for the help. I have one more question. What is designed to prevent multiple devices on an Ethernet network from transmitting at the same time? I read the book and it states that despite transmission defferal two or more ethernet hosts can transmit at the same time resulting in a collision. So I assume that Transmission defferal is the answer? Thanks | |

| The PDU that hubs are concerned with is IPX correct? This is the only PDU that I found associated with hubs. | |
