Which two statements are true with clustered Data ONTAP support of IPv6? (Choose two)
The correct answer is A. IPv4 and IPv6 configurations are supported on the cluster management LIF B. IPv4 and IPv6 configurations are supported on the same data LIF. Clustered Data ONTAP supports dual-stack IPv4/IPv6 on cluster management and data LIFs, but not on the cluster interconnect.

Why each option
Clustered Data ONTAP supports dual-stack IPv4/IPv6 on cluster management and data LIFs, but not on the cluster interconnect.
The cluster management LIF supports both IPv4 and IPv6 addresses, allowing administrators to manage the cluster over either protocol stack.
A data LIF can be configured with both an IPv4 and an IPv6 address simultaneously (dual-stack), enabling client access over either protocol on the same logical interface.
A data LIF is always scoped to a single Vserver regardless of the IP version used; IPv6 does not grant a LIF the ability to serve multiple Vservers.
The cluster interconnect uses dedicated link-local addresses for internal node communication and does not support general IPv4/IPv6 dual-stack configuration by administrators.
