DHCP Active\Standby Failover - Server 2012 R2

We are looking to configure DHCP HA for our server 2 x 2012 DCs\DHCP servers. We want to implement an active\standby config on each scope. To test, we are thinking of temporarily deactivating the active scope to initiate the fail over to the passive scope (on the secondary DHCP server).

Does anybody have any experience with this and would deactivating the scope initiate the fail over and vice versa to fail back? Also, is there anything to look out for in terms of failing over and failing back?

Just curious why you want to use an Active/Standby method rather than using a split scope approach? Why have 1 server sitting doing nothing while the other handels all the load.

I have mainly setup split scope scenarios and this works great. I have done some testing in lab environments for failover and that is the intent is if you disbale a dhcp scope the other standby machine will failover.

What you might want to do as a test is create another scope and only have a few nodes that us it and then just failover that one, as a test. Doing this in a test enivornment first would be the best approach if you have one if not then do it with a test scope.

I have used the below technet for all of the steps and it worked for me.
