CORRECTED (Previously B) Your network contains an Active Directory domain named contoso.com. The
domain contains a server named Server1 that runs Windows Server 2012 R2 and has the DHCP Server server
role installed. Server1 has an IPv6 scope named Scope1.
You implement an additional DHCP server named Server2 that runs Windows Server 2012 R2.
You need to provide high availability for Scope1. The solution must minimize administrative effort.
What should you do?
A.
Install and configure Network Load Balancing (NLB) on Server1 and Server2.
B.
Create a scope on Server2.
C.
Configure DHCP failover on Server1.
D.
Install and configure Failover Clustering on Server1 and Server2.

Configure DHCP failover on the server that created the scope. In this case Server1 created Scope1 therefore
DHCP Failover should be configured on Server1
I believe it’s B as we’re talking IPv6:-
“DHCP failover in Windows Server 2012 provides support for a maximum of two DHCP servers, and the failover relationship is limited to IPv4 scopes and subnets. Network nodes using Internet Protocol version 6 (IPv6) typically determine their own IPv6 address using stateless IP auto configuration. In this mode, the DHCP server delivers only the DHCP option configuration, and the server does not maintain any lease state information. A high availability deployment for stateless DHCPv6 is possible by simply setting up two servers with identical option configuration.”
I am going to agree with you. I created an IPv6 Scope in my dhcp server and I don’t see a way of configuring failover on the server level unless it is within a cluster. The question does not specify a cluster. Failover can only be configured on a scope level for IPv4 scopes. It cannot be configured for IPv6 scopes.
I am going with Answer B
Agreeing with both of you.
DHCP failover and IPv6
DHCP failover is not supported for Internet Protocol version 6 (IPv6) scopes. Network adapters using IPv6 typically determine their own IPv6 address using stateless IP auto-configuration. In this mode, the DHCP server delivers only the DHCP option configuration, and the server does not maintain any lease state information. A high availability deployment for stateless DHCPv6 is possible by simply setting up two servers with identical option configuration. Even in a stateful DHCPv6 deployment, the scopes do not run under high address utilization, which makes split scope a viable solution for high availability.

I think the answer is correct according to the below link:
https://blogs.msdn.microsoft.com/clustering/2014/03/24/failover-clustering-and-ipv6-in-windows-server-2012-r2/
DHCP Failover doesn’t support ipv6 scopes.

Answer is B!
You need to configure an identical DHCP v6 Scope on different server and set the DHCP options as required.
Answer: B
IPv6 does not support failover (either as DHCP server or Failover Cluster DHCP server).
Subnet the IPv6 network and add 1 subnet as a scope in server1 & 1 subnet as a scope in server2.
