Question

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

Options

A32-bit
B64-bit
C0% aggr reserve
D5% aggr reserve

Explanation

In Data ONTAP 8.1 and later, the root aggregate is created as 64-bit by default with 0% aggregate-level space reserve.

Common mistakes.

A. 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.
D. 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%.
