• Question 104:

  You must relocate a LUN from one AFF A700 HA pair to another AFF A300 HA pair while preserving all storage efficiencies. What are two ways to accomplish this task? (Choose two.)

  A. Copy the volume.

  B. Copy the LUN.

  C. Move the volume.

  D. Move the LUN.

  Correct Answer: AB

• Question 105:

  You have a 4-node FAS8200 A300 cluster that are using ONTAP 9.3 default settings. For faster performance, you move a volume with LUNs from a node on the FAS8200 to a node on the AFF A300. You determine that your SAN host is still using all active/optimized FC paths to the FAS8300 HA pair.

  What do you need to troubleshoot to move all active/optimized FC paths to the AFF A300 HA pair?

  A. reporting nodes list

  B. host MPIO and ALUA

  C. LUN mapping

  D. igroup WWPNs

  Correct Answer: A

• Question 106:

  When does Fractional Reservation reserve space from the volume?

  A. Volume Creation

  B. LUN Creation

  C. LUN SnapMirror

  D. Volume Snapshot

  Correct Answer: D

• Question 107:

  A customer wants to move its iSCSI SAN data from the edge locations into the cloud for data analytics, while keeping the ability to access modify the data. Which two combined solutions meet the customer's requirements in this scenario? (Choose two.)

  A. Use Microsoft Azure compute resources to access the near cloud AFF SnapMirror data for analytics.

  B. Deploy ONTAP Cloud at edge locations find use SnapVault to move the data into an AFF on-premises data center.

  C. Deploy ONTAP Select at edge locations and use SnapMirror to move the data to AFF near cloud with the NetApp Private Storage (NPS) service.

  D. Use Amazon Web Services (AWS) compute resources to access ONTAP Select data at the edge office locations for analytics.

  Correct Answer: AD

• Question 108:

  You are provisioning a LUN using an ISCSI initiator on an ESX host. You disable Ethernet flow control for all ports but are experiencing Performance issues. In this scenario, which two actions would improve the performance issue? (Choose two.)

  A. Set the MTU settings 1500 for optimal performance.

  B. Dedicate your ports to ISCSI traffic.

  C. Enable jumbo frames across the entire data path.

  D. Confirm that your host .mil storage polls are connected to a different network.

  Correct Answer: BC

• Question 109:

  A customer experiences intermittent connectivity problems between an ESXi server and FC LUNs in an SVM. The customer has examined the nodes hosting the LUNs and both the disk and CPU performance are below 50% utilization. The customer examined the switch ports connected to the storage array, and they ate also below 50% utilization.

  Which two steps would you perform next in this scenario? (Choose two.)

  A. Verify that the host is using SnapDrive.

  B. Verify that the host Ethernet interfaces are using jumbo frames.

  C. Verify that the host recommended settings were applied by Virtual Storage Console.

  D. Verify that the HBA queue depth is set properly.

  Correct Answer: CD

• Question 110:
