Network Design

[Expansion]

I am trying to create a network topology for 102 PCs. 2 PCs will be for Directors use for a company. The 100 PCs will be spread over 4 branches across 1 country. Not sure what kind of topology/design would be most effective and cost efficient.

If you are familiar with what services you want to offer these places, and you are not sure what devices to use.

suggest to contact local SE to offer you better solution for your budget, This community can also help you to design. Provided more information.

where they located and what is the distance, what kind of local breakout connection you have so on.

In my opinion, set a template for the branches.  Since you know how much users there will be per site, you can assign like a /22 per site - increase/decrease based from your needs.  Then assign a VLAN like 10 (PC), 20 (WIFI) and so on. Then each VLAN you can assign like /24. 

Internet nowadays like DSL are the cheapest and also offers more bandwidth for the price.  You can use IPSec technologies, see link below:

You can look also at cloud based solutions like Meraki if you haven't bought hardware.

Hi,

If you're searching for a scenario to interconnect those branches over a WAN connection with a cost efficient solution, I would recommend going with DMVPN. Each site will have a router with an internet connection and as overlay you will implement DMVPN. This will allow you to work in a hub and spoke fashion with the possibility to have a spoke to spoke communication as well dynamically built.
