You have a DHCP server named Server1 that runs Windows Server 2012 R2. You need to configure Server1
as a stateless DHCPv6 server.
Which cmdlet should you run?

A.
Add-DHCPServerv6Scope

B.
Add-DHCPServerv6OptionDefinition

C.
Set-DHCPServerv6Class

D.
Set-DHCPServerv6OptionValue

Explanation:
The parameters Parent Domain and IPv6 DNS Server, which the installation wizard asked for during the DHCP
server role installation if you chose “enable stateless mode,” can be added manually to the Server Options
node in the DHCP management console. The Set-DhcpServerv6OptionValue cmdlet sets an IPv6 option value
at the server, scope, or reservation level.
