Which protocols does clustered Data ONTAP HA support with Infinite Volumes?
The correct answer is A. NFSv3, NFSv4.1, and SMB1.0. Infinite Volumes in clustered Data ONTAP HA support only a specific NAS protocol subset - NFSv3, NFSv4.1, and SMB1.0 - and do not support SAN protocols or all NFS versions.

Why each option
Infinite Volumes in clustered Data ONTAP HA support only a specific NAS protocol subset - NFSv3, NFSv4.1, and SMB1.0 - and do not support SAN protocols or all NFS versions.
Infinite Volumes are NAS-only constructs and are validated to work with NFSv3 for broad Unix/Linux client compatibility, NFSv4.1 for features such as pNFS and stronger locking semantics, and SMB1.0 for Windows file sharing. This defined subset reflects the architectural constraints of Infinite Volumes in the ONTAP 8.2 HA configuration.
NFSv2 is not supported with Infinite Volumes, and this choice omits NFSv4.1 which is a supported and required protocol option.
NFSv1 is not a valid or supported protocol in any modern ONTAP release, and this choice incorrectly excludes SMB and NFSv4.1 support.
Infinite Volumes support NFSv4.1, not NFSv4.0; these are distinct protocol versions with different feature sets, and SMB1.0 support is also omitted here.
NFSv3-only is incorrect because Infinite Volumes also support NFSv4.1 and SMB1.0 in clustered ONTAP HA configurations.
Infinite Volumes do not support SAN protocols such as iSCSI, FCP, or FCoE; they are exclusively NAS-capable constructs.
Concept tested: Infinite Volumes supported NAS protocol subset in clustered ONTAP
