I have been asked this question in a Cisco Packet Tracer. It is testing my knowledge of designing and implementing a vlsm addressing scheme.
The requirements are:
You will subnet the network address 192.168.72.0/24. The network has the following
Room-114 LAN will require 7 host IP addresses
Room-279 LAN will require 15 host IP addresses
Room-312 LAN will require 29 host IP addresses
Room-407 LAN will require 58 host addresses
Also a serial WAN link that requires addressing
A subnet table is asked for
Here is my solution
I was hoping someone would review my solution, and raise any problems.
I will have four /26 subnets, and the last one will be subnetted with 4 possible /28 subnets, 3 of which are unused, and 4 possible /30 subnets, 3 of which are still available. The /28 will be used for Room-114 with 7 hosts and the /30 will be used for the WAN with two hosts,
Does my solution abide by general good practices?
