What are two defaults for a new Data ONTAP 8.1 or later system root aggregate? (Choose two.)

32-bit was the aggregate default in Data ONTAP versions prior to 8.1; systems running 8.1 or later default to 64-bit for all new aggregates.

Data ONTAP 8.1 made 64-bit the default aggregate format for all new aggregates including root, enabling support for aggregate sizes well beyond the 16 TB ceiling imposed by the 32-bit format.

The root aggregate is initialized with 0% aggregate reserve by default in Data ONTAP 8.1 and later, meaning no space is pre-allocated at the aggregate level as a reserve buffer.

A 5% aggregate reserve is not the default for any aggregate on a new Data ONTAP 8.1 or later system; the default reserve is 0%.
