When using Data ONTAP 8.1 Cluster-Mode and later, what is the default for new aggregates?
The correct answer is B. 64-bit aggregates. Data ONTAP 8.1 Cluster-Mode creates all new aggregates as 64-bit by default, removing the 16 TB per-aggregate capacity ceiling of the legacy 32-bit format.

Why each option
Data ONTAP 8.1 Cluster-Mode creates all new aggregates as 64-bit by default, removing the 16 TB per-aggregate capacity ceiling of the legacy 32-bit format.
32-bit is the legacy aggregate format from older ONTAP versions and is not the default in Data ONTAP 8.1 Cluster-Mode.
Starting with Data ONTAP 8.1 Cluster-Mode, the system defaults to creating 64-bit aggregates, which support significantly larger aggregate and volume sizes than 32-bit and are required for multi-petabyte scale-out deployments.
128-bit is not a defined or supported aggregate format in any version of Data ONTAP or ONTAP.
'Cluster aggregates' is not a valid aggregate type designation in Data ONTAP terminology.
Traditional aggregates are a 7-Mode concept and are not a recognized type designation within Cluster-Mode.
'Vserver aggregates' is not a recognized aggregate classification; aggregates in Cluster-Mode are assigned to SVMs but are not typed as Vserver aggregates.
