You have been presented with the provided network topology, which represents an office network for a small-sized business. The topology consists of two Layer-3 Devices: The Core Router and the Distribution Switch. The Distribution Switch is configured as the Default Gateway for the Building A, Building B, and Internal Server networks through Inter-VLAN Routing.

One notable aspect is the presence of a Web Server that needs to be accessible by users on the internet. Additionally, there is a dedicated Server serving as the DHCP Server for the network. The client, feeling unfamiliar with these configurations, has approached you for assistance in understanding how their network should be set up.

 

Answer the questions

1.Note that the Internal Server is on a separate network to Building A/B. If a PC from Building A/B sends a DHCP request, will the Internal Server receive the request? Are there any additional configurations needed to enable the Internal Server to function as a DHCP Server for Building A/B networks?

 2.Note that the Web Server, Building A, and Building C all require access to the internet.

The Web Server needs to be accessed by users from the Internet, whereas the two Buildings just need access to the internet. The Web Server has its own Public IP Address, whereas the two Buildings are to share theirs.

How do you think NAT should be setup to allow this configuration? What NAT Types need to be used?

 3.Note that the Internal Server does not have Internet Access. How would you go about blocking this? What configuration would be made, and where?
