1.create a drawing showing a private routed network.
2. On this drawing you will show your placement of the following, and explain why they were placed there (you can use one or more of the servers/router listed in your drawing):

•a) DNS Server(s)
•b) DHCP Server(s)
•c) Routers
•d) Application Server(s)
•e) Clients

would this be right ?
or
what can be a better set up useing the above things..
