Lab Exercise 3 (In lab exercise)
Simulate the real network environment by using following devices and Services.
Maximum number of network Devices used.
 2 PCs
 1 switch
 2 Servers
Network services and servers configured are HTTP and DNS
IP address configuration of Devices

192.168.1.3
255.255.255.0
192.168.1.4
255.255.255.0
Check the end to end connectivity between the devices by using PING command.
All devices must be connected and access across the network
Using simulation mode check the PDUs’ detail of every device as described in LAB-3.
