topology for 5 story building - cisco

First, Is there a budget assocaited with this Case?

You would need an IDF on each floor which should have your networking gear inside. Inside would be your patch panel/punchdown block and your switch. Most likely you need only one switch since you only have 20 hosts on the floor and there are 24 port switches out there. Plus you can use a port on the switch to connect your WAP on the top 2 floors.

On the ground floor would be your MDF. Inside you would have your router that connects your switches from each floor, including the first floor switch. The cabling connecting each floor should be fiber.

You could put a subnet per floor. Also, you could divide departments with VLANs if you are that far into the course that you know how to do that.

Not sure if i missed anything, any more questions go ahead and post

The cabling from each outlet comes into the IDF to a patch panel which allows all the runs to be done first. Now you are just working with smaller patch cables instead of the long cable runs coming out of the cieling. Also, the long runs from the jacks come into the IDF and once punched down are marked for a certain outlet.

It is easier to work with shorter cable runs to networking devices instead of working with the actual run and trying to make it work; ie. if you move a networking device, the cable may no longer reach because it was made a certain length. You don't want to be tugging on that long cable run.

This makes it easier when plugging and unplugging the patch cables from the networking device because you know where the cable is going, and what port it should be plugged into ( if the network is setup this way).
