You are implementing an ONTAP 9.5 AFF A300 SAN cluster with the NVMe, FC, and FCoE protocols. Referring to the exhibit, which three protocols and physical port pairs are supported? (Choose three.)

NEW QUESTION 5

You are configuring a VMware sphere host for FC access to a Netapp ONTAP cluster. In this scenario, which two tasks does Netapp recommend performing on the Vsphere host? (choose two)

• A. Set the queue depth on the host to 8
• B. Update the HBA driver
• C. Zone the host by using the host WWNNs
• D. Use the Netapp Virtual Storage Console to configure the host settings

Answer: BD

Explanation:
Zoning the host using WWNNs is not recommended. Netapp always recommends to use WWPN to zone correctly.
We can not stablish a queue depth value because we don't have the amount of ports and hosts to calculate the recommended queue depth
Installing VSC and updating the HBA driver are best practices recommended by Netapp

• B. iSCSI ACLs are applied to the initiator configuration to provide an IP address of the targets.
• C. CHAP encrypts all iSCSI session I/O.

NEW QUESTION 9

An administrator is migrating from a third-party's SAN to a newly purchased FAS9000. The administrator decides to use the NetApp Foreign LUN Import (FL1) process.
What must the administrator do for this process to work properly?

• A. Create multiple igroups for the Initiator ports.
• B. Create six distinct zones that include specific ports within each zone.
• C. Zone target ports of source storage with initiator ports of destination storage.
• D. Make the destination LUN larger than the foreign LUN.

Answer: C

NEW QUESTION 10

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:
