- A new network is required to connect a new building on campus with (2) wings.

Question

- A new network is required to connect a new building on campus with (2) wings.

- Each wing will require a wired network with (100) wired computers in each.

- The wired network in each wing will require (4) managed Ethernet switches

- Each wing will also require a wireless network with up to (100) IP addresses for mobile users.

- The wireless network in each wing will require (4) managed 802.11 wireless access points

-You are told to use either (1) or (2) IP subnets for this new building. Your choice.

- If one subnet, the network will also require one additional address for the subnet router interface. If two subnets, the network will require two additional addresses for router interfaces.

- The network manager asks you to assign IP addresses from the range: 192.168.50.0 to 192.168.51.255 (which is 512 total addresses)

1- How many total IP addresses will be needed for computers and mobile users? ___________

2- How many total IP addresses are needed for Ethernet switches, wireless access points, and router interfaces for this new network? Show how you arrived at that number. _________________________________________________________________________

3- How many subnets will you use? Describe how you chose, and how you will use them:

__________________________________________________________________________________

4-Show your network address(es) including subnet size(s)

__________________________________________________________________________________

5- Show your broadcast address(es)

Explanation / Answer

Hi

Answer:

1) How many total IP addresses will be needed for computers and mobile users .

Answer:It is around 400 (100 LAN & 100 wifi users in each wing).

2)How many total IP addresses are needed for Ethernet switches, wireless access points, and router interfaces for this new network?

Answer: To cater 100 LAN users we need at least three switches (two 48 port one 24 ports for each wing ). however in question it is already specified the number of switches =4 . we have two option to manage the switch . A) treat all switch as individual there 4 IP required for each wing so total 8 IP in both wing . B)These switch can be in virtual chasis one master and others are as member. only one IP to be used in each wing .so total 2 IP address for switches.

Two cater wifi user we have 4 access points there 4 IP would be requiring in each wing therefore total 8.

3)How many subnets will you use.

Answer: we can use two /24 network , one for each wing since the user +device IP not exceeding 254.

192.168.50.0/24 and 192.168.51.0/24.

4)Show your network address(es) including subnet size(s):

Answer: here we are considering the user network (VLAN) and device network (VLAN)to be same in each wing .

therefore

for Wing A

192.168.50.0=network address

192.168.50.255=broadcast address

192.168.50.1 to 192.168.50.254 for users and devices

For wing B

192.168.51.0=network address

192.168.51.255=broadcast address

192.168.51.1 to 192.168.51.254 for users and devices

5) Show your broadcast address

Answer: for wing A

192.168.50.255

for wing B

192.168.51.255

Thanks
