Automatic host-side space management with SCSI T10 thin-provisioned LUNs is achieved by which feature of ONTAP?

A. fractional reserve

B. space allocation

C. space reservation

D. volume auto-grow

You have a thin-provisioned LUN that was created by using the lun create -vserver vs1 - path /vol/vol1/lun1 -size 500G -ostype windows 2008 -space-reserve disabled -space- allocation disabled command. You verify that your Windows 2016 host reports 200 GB free on lun1. However, lun1 shows 0 bytes free on the storage cluster.

What should you do to solve this problem?

A. Change the LUN -space-allocation parameter to enabled.

B. Change the LUN -ostype parameter to windows_gpt.

C. Change the LUN -space-reserve parameter to enabled.

D. Rescan the LUN disk in your Windows host so that it will notify NetApp about the free space.

An administrator who is using the Virtual Storage Console (VSC) creates a new FC datastore on an existing volume. While the datastore was provisioned, two hosts were in maintenance mode. When the maintenance was completed, the two hosts do not have access to the new datastore, but they have access to other datastores on the same volume.

In this scenario, what caused this result?

A. The VSC cannot create datastores while hosts are in maintenance mode.

B. During host maintenance, the FC HBAs were replaced with different FC HBAs.

C. The VSC created a new igroup that contains only the hosts that were online during the datastore creation.

D. After creation using the VSC, the administrator needs to create a LUN mapping.

Which two features does Assymmetric Namespase Access (ANA) support? (Choose two.)
