Your network contains an Active Directory domain. The domain contains a site named Site1.
All of the client computers in Site1 use static IPv4 addresses on a single subnet. Site1 contains a Storage
Area Network (SAN) device and two servers named Server1 and Server2 that run Windows Server 2012.
You plan to implement a DHCP infrastructure that will contain Server1 and Server2. The infrastructure
will contain several IP address reservations. You need to recommend a solution for the DHCP
infrastructure to ensure that clients can receive IP addresses from a DHCP server if either Server1 or
Server2 fails.
What should you recommend? (Each correct answer is a complete solution. Choose all that apply.)
A.
Configure all of the client computers to use IPv6 addresses, and then configure Server1 and Server2
to run DHCP in stateless mode.
B.
Configure Server1 and Server2 as members of a failover cluster, and then configure DHCP as a
clustered resource.
C.
Configure a DHCP failover relationship that contains Server1 and Server2.
D.
Create a scope for each server, and then configure each scope to contain half of the IP addresses.

B,C.

Option D is for IPv6 “high availability” as you cannot configure IPv6 in failover mode.

I call BS.
C and D is the answer. You don’t need to configure a FoC with DHCP as it is built right into the DHCP service. Once you create the DHCP failover (say, on Server1) you add the partner server (Server2), then you tell it the percentage of addresses to are available to each node.
Answer B has no place in DHCP failover.

C,D are the most common one, but B is also an option as it’s an supporterd fail over cluster role. –> https://technet.microsoft.com/en-us/library/dn505754(v=ws.11).aspx
