NEW QUESTION 32
Click the Exhibit button.
You have an existing legacy Fibre Channel SAN environment and have deployed an ONTAP AFF A800 cluster. You are planning to migrate a NetApp Foreign LUN Import using the existing SAN environment.

- A. Configure the CNA to target mode.
- B. Configure the CNA to initiator mode.
- C. Configure the FCP to initiator mode.
- D. Configure the FCP to target mode.
Answer: C
NEW QUESTION 33

- A. The space-slo parameter must be set to none.
- B. The space-allocation parameter must be enabled.
- C. The space-slo parameter must be set to semi-thick.

Answer: B
NEW QUESTION 34
An administrator has migrated an ISCSI LUN with Foreign LUN Import (FLI) tool. The migrated LUN is presented on the new system, but it is not visible to the host. In this scenario which additional action must be completed to make the LUN visible?
- A. Install ANA software on the host
- B. Stop the FCP service
- C. Map the LUN to an ISCSI igroup
- D. Bind the igroup to a port set
Answer: C
Explanation:
Installing ANA is related with NVMe protocol
Binding an igroup to a port set will only limit our paths
Stopping the FCP service will not affect at anything, because this is an ISCSI LUN When you migrate ISCSI using FLI, you need to map the LUNs to an igroup where the destination arrays is added, after the LUN has been imported, you can create a new iSCSI igroup and add the hosts to the igroup You can find more information on this link:

NEW QUESTION 43
You created a LUN in a new volume on your Netapp ONTAP cluster. You enabled the default snapshot schedule and enabled snapshot autodelete on the volume. In this scenario, in which three situations does the snapshot autodelete feature automatically delete snapshot copies in the volume? (choose three)
- A. The volume is nearly full
- B. The snapshot reserve space is nearly full
- C. The LUN is nearly full
- D. The aggregate is nearly full
- E. The overwrite reserve space is full
Answer: A,B,E
Explanation:
Depending on what is selected in the "Trigger" option, Snapshot Autodelete will automatically delete a snapshot when, either the volume space utilized, or the snapshot reserve reaches a threshold capacity specified below.
Automatic deletion of Snapshot copies from flexible volumes Data ONTAP can automatically delete one or more Snapshot copies on the volume, provided the Data ONTAP Snapshot copy autodeletion policy is enabled and set to trigger when the overwrite reserve is nearly full on the volume.
