Appreciate if any expert can explain on the answer.

Thanks!

A few key ingredients are missing:
Is there a requirement of protocols to be used?
Is there an requirement on cabling system?

Nope, our lecturer didn't mention on that, I have done it but get it wrong, didn't realize the need to consider the distance

Thanks!

@Soulja if you go for ethernet (UTP/Fibre).
Or
a) coax,
b) coax,
c) coax...
if you go for ICS, CATV, broadband, (also for ethernet).
Note that speeds have not been specified so:
could also be:
a) 2 wire phone
b) 2 wire phone
c) 2 wire phone
If simple current loop is used, etc. RS232, RS422, RS423, RS485....
So your milage may vary depending on required technology.

I believe it being a new networking class, that the expected answer isn't supposed to go a mile deep, and the presumed answers would be based on common and/or basic deployments used.

Regarding coax, I am not aware of any that exceeds 500m. Regarding 2 wire i would put that in the category of twisted copper so, distance limited.

The presumed answer will most likely be what was included in the lecture and reading materials - and not more.

@soulja, 2 wire copper could have 100's of KM (think telegraph....) or POTS (about 5 KM which would severly limit DSL speeds)
For decent bandwith the length needs to be limited.

I suspect that the class material told you which cable type is best for certain distances. Then you just match them up. If that doesn't work then I'd be surprised.
For example, cat6 is good for 100 meters.
What if you use cat6 for every connection that's less than 100 meters?
Then what's left to deal with the longer links?

Thanks for the elucidation. I stand corrected. :)

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
