1) Using the diagram provided please identify the routers and the switches? (10 points)
Device Image Name Functionality
Router A router is a networking device whose
functionality is to route packets from one to
another. The redirects the packets as per the
routing table configuration.
Switch A switch is a networking device that expands the
operability of a network. That is to say, it
provides more ports for the computing devices
to connect to the network.
(Todd, 2016)
2) Please Assign IP addressing to each of the devices shown. If a device is meant to be a DHCP
client, then indicate as such. For each system, please include the subnet mask and gateway for
each system. If a system does not have a gateway address, indicate by not applicable. (Add
additional rows as needed) (50 points)

Explanations and assumptions
Assumptions
i. We assume that our public IP as provided by ISP is 200.200.167.2/2.
ii. We assume that our private IP is 172.16.168.0/24.
iii. We assume that system admin system is in a different VLAN
iv. We assume that ISP router is represented inform of a cloud.
v. We assume that the router, switch and cloud interfaces are connected as image below
Explanations
Given the IP address of 172.16.168.0/24 we had to come up with five subnets. Four of the subnets are
treated equally in terms of number of address hosts (254 valid hosts) except for the subnet that is
between the upper and lower router whose address host has only 2 hosts.
