NS0-158 · Question #117

What will the storage aggregate create -aggregate aggr0_rg0 -diskcount 40 -maxraidsize 20 -nodes cl-01 -disktype SAS command do?

The correct answer is A. It creates a new aggregate named aggr0_rg0 with two RAID-DP RAID groups of 20 SAS drives. The command creates a NetApp aggregate with 40 SAS disks on a specific node, limiting the size of individual RAID groups to 20 disks.

Why each option

The command creates a NetApp aggregate with 40 SAS disks on a specific node, limiting the size of individual RAID groups to 20 disks.

AIt creates a new aggregate named aggr0_rg0 with two RAID-DP RAID groups of 20 SAS drivesCorrect

The `storage aggregate create -diskcount 40 -maxraidsize 20` command instructs NetApp ONTAP to create an aggregate using 40 disks, with a maximum of 20 disks per RAID group. This configuration automatically results in the creation of two separate RAID-DP (the default RAID type for aggregates) RAID groups, each containing 20 SAS drives.

BIt creates a new aggregate named aggr0_rg0 with one RAID-DP RAID group of 40 SAS drives on

This is incorrect because the `-maxraidsize 20` parameter explicitly prevents the creation of a single RAID group with 40 drives.

CIt creates a new aggregate named aggr0_rg0 with two RAID4 RAID groups of 20 SAS drives on

This is incorrect because ONTAP aggregates use RAID-DP as the default RAID type, not RAID4, when creating new aggregates with multiple data disks.

DIt creates a new aggregate named aggr0_rg0 with two RAID4 RAID groups of 20 SAS drives on

This is incorrect as it specifies RAID4, but ONTAP aggregates use RAID-DP by default for data protection, not RAID4.
