Assumption: All subnet values can be used and the all "0"s is the first subnet.
Question 1 - You have been assigned the 160.50.100.0/24 network address block. (10Marks)
Define an extended network prefix that allows the creation of 45 Hosts on each subnet.
a) List the network prefix and the equivalent Subnet Mask (2)
b) What is the maximum number of valid Hosts that can be assigned to each subnet AND the maximum number of subnets that can be defined?(2)
c) List the subnets with their prefix and subnet mask below (2)
d) List the first and last usable IP address in the second subnet. (2)
e) What is the broadcast address of the first and second subnet? (2)
Question 2 - You have been assigned the 14.0.0.0/8 class A network address block to deploy a Large Corporate network (10 Marks)
Subnet this network to be able to support approximately 250 networks (Subnets),
a) List the network, prefix and equivalent subnet mask. (2)
b) What is the maximum number of valid Hosts that can be assigned to each subnet AND the maximum number of subnets that can be defined?(2)
c) List the first 4 subnets with their prefix and subnet mask below (2)
d) List the first and last usable IP address in the second subnet. (2)
e) What is the broadcast address of the first and second subnet? (2)
Question 3 (VLSM) - You have been assigned the 135.16.0.0/22 network address block to deploy a network, using VLSM, subnet the above range to fulfill the following concurrent (All requirements must be met with no address re-use) requirements (10 Marks)
2 networks that can support at least 190 devices/users
2 networks that can support at least 120 devices/users
2 networks that can support at least 60 devices/users
4 networks with 25 devices/users.
a) What is the network prefix used to support the first requirement, 2 networks with 190 devices / users? List the networks with their prefix and subnet mask (2)
b) What network prefix is used to support the second requirement, 2 networks with 120 devices/users? List the networks with their prefix and subnet mask (2)
c) What is the prefix used to support the last requirement, 2 networks with 60 devices/users? List the networks with their prefix and subnet mask (2)
d) What is the prefix used to support the last requirement, 4 networks with 25 devices/users? List the networks with their prefix and subnet mask (2)
e) What is the supernet (Summary Route) that can be used to represent each of the above subnet groups? (One supernet/route with prefix/Mask for each requirement group a, b, c and d) (2)
Question 4 - You have been asked to design an IP addressing plan for a medium size corporation, Corporation (X) converting to an IP network. The corporation currently has 85 locations but plans to expand to approximately 100 Locations within the next year. Each location should have a user network that can support up to 100 users, a wireless network that can support up to 50 users, a network to support servers and printers that can support up to 30 devices. In addition to these requirements, they also have a large data centre that requires at least 75 networks that can support 200 Devices per subnet. Your design should also take into account addressing for the point to point links between the datacentre and the remote offices.
Using the 142.146.0.0 /16 Network address block, design a structured addressing plan that addresses these requirements, take into account summarization of networks for each location and identify how much address space remains for future expansion in each block of addresses. (20 Marks)
