To create a 64-bit aggregate, which optional switch/flag/parameter/option to the aggr create command must be
included?

A.
b 64

B.
B 64

C.
l 64

D.
L 64

E.
No optional switch/flag/parameter/option is needed because 64-bit aggregates are the default

The command to create a 64-bit aggregate is the same aggr create command that is present in Data ONTAP
7G for aggregate creation. The aggr create command has a new flag, -B, to specify the type of aggregate to
create. It takes a value of either 32 or 64 and creates the respective type of aggregate. Therefore the aggr
create command with -B 64 creates a 64-bit aggregate. The aggr create command without the -B flag by
default creates a 32-bit aggregate.
Here are some commands for creating different aggregate types in Data ONTAP 8.0:
Creating a 64-bit aggregate:
aggr create aggr_64 -B 64 5
Creating a 32-bit aggregate using –B flag:
aggr create aggr_32 -B 32 5
Creating a 32-bit aggregate without using –B flag:
aggr create default_aggr_32 5
Note: the man pages do not include this option in later versions of DOT because 64-bit is now the default.
