Several Questions

Peperpiz

Hey. I'm currently involved in the CCNA Certification program. CCNA Semester 1.

I have some questions.

1. Lets say you have one collision domain. What's the maximum number of hosts you should have on that collision domain, before you decide to add another collision domain? Same with the broadcast domain; how many hosts max until you should think about adding another broadcast domain?

2. I know that switches are capable of operating at full duplex, however, how do you configure that? By that I mean, how do you let the switch know that you want it to be full duplex?

3. What is Proxy ARP?

4. What is dial up networking?

Help would be greatly appreciated!

hey there

Most of these questions can be googled.

ProxyARP: http://www.cisco.com/warp/public/105/5.html

Dial-up Networking / DUN is your normal dial-up via a modem (56k V series) to your ISP (POP - Point of Presence) where they supply you with your gateway linking you to the net.

Full duplex on switches has the capability to negotiate full duplex or half duplex, depending on the device to which it is connected.

Collision and broadcast domains dont really have a particular maximum number of devices. If you an expert in networking you could design your network to be collision free, it depends on your applications as well. How much bandwidth you using. With broadcast domains, that really depends on your business case and design. If you have a good switched network design, you can use VLANs to spilt up broadcasts...

But try google...and cisco's website

Hope i help. Keep cool

The proxy ARP link given by cisco_trouble is a real good one with example
