NEW QUESTION 3

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 snapshot reserve space is nearly full
• B. The LUN is nearly full
• C. The overwrite reserve space is full
• D. The volume is nearly full
• E. The aggregate is nearly full

Answer: ACD

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. You can find more information on this link:

NEW QUESTION 4

During maintenance of an AFF A250 node, you want to move the SAN LIFs that are members of a port set. In this scenario, which two statements are true? (choose two)

• A. You must disable SLM for the node that hosts the LIF
• B. You need to disable the zoning of the LIF WWPN
• C. The LIF must be removed from the port set
• D. You must take the SAN LIF offline

Answer: CD

Explanation:
If the LIF is a member of a port set, the LIF must have been removed from the port set before the LIF can be moved to a different node.
Change the status of the LIF to down (offline) You can find more information on this link:

Referring to the exhibit, which three steps are required to accomplish this task? (Choose three.)

• A. Issue the ucadmin modify -node AFF_1 -adapter 0e -mode FC -type target command.
• B. Issue the ucadmin modify -node AFF_1 -adapter 0e -mode FC -type initiator command.
• C. Restart the FC service.
• D. Take ports 0e and 0f offline.
• E. Reboot the node.

Answer: BCD

NEW QUESTION 6

Exhibit.

Referring to the exhibit. What are two viable scenarios to test LUN multipathing on Host 1? (Choose two.)

• A. Reboot one of the switches.
• B. Disable one of the FC LIFs on Controller 1.
• C. Disconnect one of the host cables.
• D. Reboot Host 1.

Answer: AC

NEW QUESTION 7

Exhibit.

An administrator has an AFF A200 HA pair.
Referring to the exhibit, how many 10 Gbps connections would the customer have on a single node for SAN host connectivity?

• A. 4
• B. 6
• C. 7
• D. 2

Answer: A

NEW QUESTION 8

You have a 100GB volume with the space guarantee set to volume, This volume contains two space reserved 20 GB LUNs. Both LUNs are at 50% use. You then create a snapshot copy of the volume. No
modifications were performed since the snapshot copy was completed, and all actions were performed using the CLI. In this scenario, how much free space does the volume have?

• A. 60 GB
• B. 20 GB
• C. 40 GB
• D. 80 GB

Answer: A

Explanation:
Both LUN created are inheriting the space reserved parameter from its volume parent, so both LUNs are thick provisioned using 20 GB each one of them and the snapshots have not increased because
there has not been any changes since their creation 100GB - 20 GB - 20GB

NEW QUESTION 9


Referring to the exhibit, which two elements are required for NVMe host access with ONTAP 9.5 and using supported AFF nodes? (Choose two.)

• A. You need 16 Gb FC HBAs installed in the AFF nodes.
• B. You must have the license installed for NVMe support in the cluster.
• C. You must have the license installed for FC support in the cluster.
• D. You need 32 Gb FC HBAs installed in the AFF nodes.

Answer: CD

NEW QUESTION 10

• C. A demo license is used.
• D. Only one NVMe data LIF can be configured per SVM.

Answer: B

NEW QUESTION 11
