IP calculation Problem- number of local area networks (LANs)

IP calculation Problem

I have a school assignments about IP that I wanna get help.

Case Description
A company plans to set up a number of local area networks (LANs) for its divisions as follows:

■sales division [LAN-SA: 25 computers; 1 file server; 1 network printer]
■marketing division [LAN-MA: 18 computers; 1 file server; 1 network printer]
■purchase division [LAN-PU: 12 computers; 1 file server; 1 network printer]
■accounting division [LAN-AC: 4 computers; 1 network printer]
■human resource division [LAN-HR: 5 computers; 1 network printer]

All computers will be able to access the Internet. The existing network equipment that the company has is listed below:

■one router (to connect to the Internet)
■two 4-port routers
■two 4-port switches
■two 24-port switches
■one 48-port switch

The private CIDR IP (v4) address ranged from 192.168.1.0 - 192.168.1.255 is used for all the computers and network devices for the company. Each device obtains its IP from a DHCP server when it is switched on.

(a) Suppose a fixed-length subnet mask is used, what should it be? Show all the relevant calculation. Give the range of IPs for each LAN.

(b) Suppose a fixed variable-length subnet masking (VLSM) technique is used, show all the relevant calculation. Give the range of IPs for each LAN.

thankssssss

thankssssss

U can use with fixed mask 255.255.255.224 => 8 subnets and configure on 48-port switch 2 vlans for LAN-SA - 30 ports, LAN-PU-18
24port switch for LAN-MA
24ports to 2 vlan LAN-AC, LAN-HR

To first router u can connect 48ports switch via 2 ports and first 24ports switch.
To second router u can connect 2 vlan from second 24ports switch.
And last thingi u can connect two routers thorought 4 port switch to main router.

When u dont understandt me please contact me on ICQ 334632889

I have only CCNA1 but in thic course we was planning a network with VLSM and fixed lenght mask.
