• Question 162:

  An administrator has a new AFF A220 system with two DS224C disk shelves and wants to validate if the shelf cabling is correct. Which resource would be used to accomplish this task?

  A. Config Advisor

  B. OnCommand Unified Manager (OCUM)

  C. OneCollect

  D. Interoperability Matrix Tool (IMT)

  Correct Answer: A

• Question 163:

  While expanding a 200 GB LUN in an ONTAP 9.4 system, the following error is observed:

  

  What is the cause of this error?

  A. The volume auto-grow is disabled.

  B. The LUN reached maximum capacity.

  C. The LUN can be expanded up to 10 times its original size.

  D. Space reservation is enabled.

  Correct Answer: A

• Question 164:

  An administrator who is using the Virtual Storage Console (VSC) creates a new FC datastore on an existing volume. While the datastore was provisioned, two hosts were in maintenance mode. When the maintenance was completed, the two hosts do not have access to the new datastore, but they have access to other datastores on the same volume.

  In this scenario, what caused this result?

  A. The VSC cannot create datastores while hosts are in maintenance mode.

  B. During host maintenance, the FC HBAs were replaced with different FC HBAs.

  C. The VSC created a new igroup that contains only the hosts that were online during the datastore creation.

  D. After creation using the VSC, the administrator needs to create a LUN mapping.

  Correct Answer: C

• Question 165:

  You currently have a FAS8200 with ONTAP 9.5. You want to expand the front end FC I/O capabilities. However, you are unsure which target adapters are supported. What would you use to confirm which adapters are supported with your current configuration?

  A. Hardware Universe (HWU)

  B. Upgrade Advisor

  C. OneCollect

  D. Interoperability Matrix Tool (IMT)

  Correct Answer: A

• Question 166:

  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 5000 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: A

• Question 167:

  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 168:

  An administrator is asked to configure NVMe on an ONTAP 9.5 cluster for host access. Which three steps must the administrator perform to accomplish this task? (Choose three.)

  A. Create a namespace.

  B. Provision a subsystem.

  C. Configure the FC port.

  D. Gather the IQN from the host initiator software.

  E. Gather the NQN from the host system.

  Correct Answer: ABE

• Question 169:

  

  You have an existing 2-node AFF A300 cluster with premium bundle licensing applied. You need to have consistently low front end latency, and have determined that NVMe satisfies this requirement. Referring to the exhibit, which two actions would accomplish this task? (Choose two.)

  A. Add a UTA2 adapter to each of the two AFF A300 nodes.

  B. Add a 32 GB FC HBA to each of the two AFF A300 nodes.

  C. Apply the license for FCP.

  D. Apply the license for NVMe.

  Correct Answer: B

• Question 170:

  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
