• Question 81:

  Click the Exhibit button.

  

  A customer has an AFF A700 connected to a Cisco switch and has verified connectivity but cannot see any LUNs. The customer issued the run -node scaling-01 -command fcp topology show command to verify the connection.

  Referring to the exhibit, what needs to be enabled on the Cisco switch?

  A. Trunking needs to be enabled.

  B. VSAN needs to be enabled.

  C. NPIV needs to be enabled.

  D. VFC needs to be enabled.

  Correct Answer: D

• Question 82:

  You are provisioning storage to an ESX host that uses iSCSI.

  According to NetApp best practice, which three actions accomplish this task? (Choose three.)

  A. Enable the iSCSI service.

  B. Bind the iSCSI ports to the software iSCSI adapter.

  C. Install Virtual Storage Console (VSC) for VMware.

  D. Enable BGP on the switch.

  E. Configure MTU 1500 on the switch.

  Correct Answer: BCE

• Question 83:

  You want to ensure maximum performance of iSCSI LUNs on an AFF A220. In this scenario, which two actions will accomplish this task? (Choose two.)

  A. Disable flow control.

  B. Configure virtual LAN (VLAN).

  C. Enable flow control.

  D. Enable jumbo frames.

  Correct Answer: CD

• Question 84:

  Click the Exhibit button.

  

  You have a requirement to serve LUNs with under 200 microsecond latency using local server lass memory. You also are required to use a shared SAN.

  Using MAX Data as shown in the exhibit, which two LUN access protocols are supported with this solution? (Choose two.)

  A. iSCSI

  B. FCoE

  C. FC

  D. NVMe

  Correct Answer: AC

• Question 85:

  A company has 20 ESX hosts. Ten of the hosts are connected using FC, and the rest are connected over iSCSI. The FC host HBA queue depth is set to 32, and the iSCSI LUN queue depth is set to 64. The FC hosts are now experiencing random connectivity issues.

  In this scenario, what would be the reason for the disconnects?

  A. The FC host has a lower queue depth.

  B. According to the IMT, unsupported HBA firmware is in use.

  C. All of the hosts are part of the same cluster.

  D. The queue depth is not consistent across the cluster.

  Correct Answer: A

• Question 86:

  You have a 4-node cluster with an AFF A300 HA pair and a FAS8200 HA pair. You plan on using the default storage efficiency settings. With inline data compaction, you estimate that you can save 6% of storage space. AFF A300 volumes that use under 5,000 IOPS are moved to a FAS8200 using the volume move command.

  In this scenario, what happens to the data after the volume is moved? (Choose two.)

  A. The new written data is not compacted.

  B. The existing data is compacted.

  C. The new written data is compacted.

  D. The existing data is not compacted.

  Correct Answer: AB

  A. Enable both inline and post process efficiencies.

  B. Enable always-on compaction.

  C. Enable always-on deduplication.

  D. Enable compression.

  Correct Answer: AC

  D. 8

  Correct Answer: B

• Question 89:

  Click the Exhibit button.

  

  You are asked to serve iSCSI LUNs in an existing SVM on your AFF A220 using ONTAP 9.5. You verified that the iSCSI license is configured on your cluster and that the iSCSI protocol is enabled.

  Referring to the exhibit, what is needed to allow hosts to log into the iSCSI target?

  A. Create new LIFs with the iSCSI data protocol.

  B. Create new igroups with the host IQNs.

  C. Add iSCSI to the data protocol of the existing LIFs.

  D. Map LUNs to the igroups.

  Correct Answer: D

• Question 90:

  In this scenario, which front end configuration is required for nondisruptive host LUN failover between sites?

  A. an intercluster LIF

  B. a stretched Layer 2 network

  C. IPv6

  D. a stretched VSAN
