NS0-193 Online Practice Questions and Answers

You have configured an ONTAP system. You want to verify that AutoSupport is being delivered to NetApp. In this scenario, what are two ways to accomplish this task? (Choose two.)

A. Review AutoSupport messages in Active IQ.

B. Review the AutoSupport section in OnCommand Unified Manager.

C. Review the AutoSupport section in OnCommand System Manager.

D. Use the system node autosupport history show command.

During a maintenance window, the administrator attempts to take over node-01 from node-02. The

command failed, and the following message was displayed:

Error: command failed: Failed to initiate takeover. Reason: Node can't see some of the partner's disks.

What should the administrator do in this scenario?

A. Look for missing nodes using the storage disk show -fields nodelist command.

B. Look for missing nodes using the storage aggregate show -fields node command.

C. Look for missing nodes using the storage failover show -fields node command.

D. Look for missing nodes using the storage pool show -fields node command.

Which two statements are true about space-reserved LUNs? (Choose two.)

A. If the LUN's volume has a space guarantee of "none", then free space is allocated to the LUN at creation time.

B. If the LUN's volume has a space guarantee of "volume", then free space is allocated to the LUN at write time.

C. If the LUN's volume has a space guarantee of "volume", then free space is allocated to the LUN at creation time.

D. If the LUN's volume has a space guarantee of "none", then free space is allocated to the LUN at write time.

You provision a new ONTAP volume to use as a VMware vSphere NFS datastore. You successfully mount the volume to the vSphere (ESXi) hosts, and you can read, write, and delete small (less than 1 KB) test files. However, you cannot upload large files or Storage vMotion VMs to the new datastore. You verify that the volume is reporting adequate free space.

Which action should you perform to troubleshoot this problem?

A. Verify that the NFS LIF is on its home port.

B. Verify the MTU configuration along the network path.

C. Verify that the security style is set correctly on the volume.

D. Verify that the export policy is correct for the volume.

Your SAN customer is experiencing database latency, that is backed by an AFF A300 cluster. The LUNs are connected using a 16Gb fabric.

Referring to the exhibit, which two steps would you take to determine the issue? (Choose two.)

A. Inspect the controller for CPU utilization.

B. Determine if there are issues on the hosts.

C. Investigate the switch for underruns or other problems.

D. Examine the controller for faults with the SSDs.

A client is attempting to mount a UNIX security style volume using NFSv4. The client receives the "permission denied" message, but mounting NFSv3 works fine. You have confirmed both NFSv4 and NFSv3 are allowed in the export policy.

Which statement describes this behavior?

A. Extended groups for AUTH_SYS are enabled.

B. NFSv4 takes file permissions into account when mounting.

C. There is no proper name-mapping rule for the user mounting.

D. The export policy applied to the volume has superuser set to none.

Your database administrator is complaining of slow read and write performance.

Referring to the exhibit, which action would be taken to improve performance for both reads and writes?

A. Replace the node's NVRAM.

B. Move the workload to an SSD aggregate.

C. Apply a QoS minimum policy to the csdata-wid1234 workload.

D. Balance the network load among the cluster nodes.

What is NVRAM used for when a node performs a takeover?

A. The NVRAM contains all the outstanding write operations that were pending to the node that was taken over.

B. The NVRAM contains only the metadata operations that were pending to the node that was taken over.

C. The NVRAM contains only the Snapshot copies that were pending to the node that was taken over.

D. The NVRAM contains all the outstanding read operations that were pending to the node that was taken over.

Users complain that they are experiencing problems accessing production data due to timeouts. You review the QoS output for a volume that handles the manufacturing production data.

Referring to the exhibit, which command would help to identify the problem?

A. statit

B. storage disk show

C. storage failover show

D. disk show

How does SnapCenter communicate to ONTAP?

A. through the admin SVM

B. directly through a dedicated node

C. through the Service Processor

D. through a data SVM
