Hello,

I am into testing. I am new to DHCP server configuration.
in my requirement, i have to get either dhynamic and static IP address for my devices from DHCP server with different subnet.
example:
Say my 2 devices named device A and Device B
Device A should get the IP between the range 192.16.0.100 to 192.16.0.150

Device B should get the IP between the range 192.16.1.100 to 192.16.1.150

Please help me out how to configure two different subnets in the DHCP server.

regards
S Deepak

Create two scopes in the DHCP one for each subnet, then configure your router to relay DHCP requests to your DHCP server, using this command:
ip helper-address x.x.x.x
where x.x.x.x is your DHCP server IP address.

But i noticed that you are using public IP addresses in your network, why??!!
use a private IP range instead, if you don't really need the public IP.

The question was copied from coursework incorrectly, and it should be 192.168.x.x

You are right, most probably this is the case.
It seems that he changed the IP, to not look that he copied the question, but he did a big mistake.

He has to study more :)

First you should have a router with two Ethernet ports, one connected to 192.168.0.x
lets say interface IP is 192.168.0.1
and the other interface with IP like 192.168.1.1
Your DHCP server should be inside 192.168.0.x subnet.
Once you configure the router and routing works correctly, inside the configuration of 192.168.1.1 interface use the following command if supported by the router:
ip helper-address 192.168.0.x (DHCP Server IP)
If the command is not supported by the router, you can use a relay agent.

For some resources check MS exam 70-642: TS: Windows Server 2008 Network Infrastructure, Configuring.
http://www.microsoft.com/learning/en/us/exam.aspx?ID=70-642&locale=en-us#tab2

Check the preparation material.
And use Google

Good Luck
