I am an absolute newbie and beginning to slowly work through a big network+ theory study book but am struggling with some things and don't really know anyone to get help from. I have read the following practice example to try and do but just don't know where to start!! And the damn book doesn't actually have any answers for these scenarios!! Any help/explanation of how you would answer the following would be much appreciated!!!
*You are taking the role of an employee in an IT department, You have been asked to research and configure a network addressing system for a network environment. The board of your client has decided to investigate the implications of dividing the network across 3 possible new locations. One main office must be able to accommodate at least 100 hosts. the proposed other 2 new offices are only intended to provide a shop front so will need no more than 14 hosts each. Networking components should allow, where possible, for expandability in size, capacity and speed. There should be a a permanent internet gateway for entire network. Remote Management of our clients network, using terminal services technology, across the internet WAN should be available. Domain controllers shall not host services apart from DNS and DHCP. Any other required network services shall be hosted on non-Domain controller servers.
You need to design a series of subnets which would suit a network spread over 3 geographical locations, between each location there will need to be a pair of routers. each pair of routers connecting via the leased lines will require their own subnet.
1) You need to determine which subnets are required and design an appropriate addressing scheme using the network 192.168.200.0 Identify the number of subnets needed(one for each location and one for each pair of routers) for the LAN, the address ranges for each subnet and the subnet mask.
2)Identify the location and number of domain controllers, DNS servers, DHCP servers, web servers, and email servers.
3) List the server services that need to exist and that need to be configured.*
So im guessing theres 4 subnets needed? so subnet mask 255.255.255.192? Or is it more?? I have no idea where to start with the addressing stuff!! I'm struggling with subnets so please help/explain what I should have done here so i can get a better understanding and attempt the other scenarios by myself!
