What is the supported NVMe OS multipathing stack for VMware ESXi?
- A . dm-multipath
- B . MPIO
- C . NMP
- D . PVlinks
Which resource would you use to verify whether a specific SAN configuration is supported by NetApp?

You have a 2-node cluster in a single-fabric SAN. Host 1 and Host 2 are part of a VMware cluster and access the same LUNs that reside in your NetApp storage.
Referring to the exhibit, what would be a way to test whether the multipathing is properly configured in your environment?
- A . Verify whether all destination storage target ports are contained in the same zone as Host 1.
- B . Administratively set ports 0a and 0c on Controller 1 to the offline setting.
- C . Disconnect Host 1 port and verify whether Host 2 is still able to run the VMs.
- D . Power off the SAN switch.
An administrator configures NVMe within an SVM for a test environment. The administrator creates an NVMe namespace and an NVMe subsystem. The administrator then maps the namespace to the subsystem.
However, when the administrator establishes a connection to a supported host, the following error message appears: No discovery log entries to fetch.
What is the solution to this error?
- A . Add the host WWPN to the subsystem
- B . Disable the host HBA and re-enable it to clear the buffers
- C . Add the host NQN to the subsystem
- D . Use the nvme ns-rescan /dev/nvme0 command to rescan the bus
After the addition of extra DS224C disk shelves, you notice that the output of the system node run – node node_1 sysconfig command shows Mixed-path. You need to investigate why the additional shelves are providing this error.
In this scenario, which two tools would help diagnose this issue? (Choose two.)
- A . Config Advisor
- B . Active IQ
- C . Hardware Universe (HWU)
- D . Interoperability Matrix Tool (IMT)
A customer’s NetApp infrastructure is reaching end-of-life (EOL), and they want to inventory their NetApp cluster. The customer wants to make sure that the proposed technical refresh satisfies their growing data demands.
Which two tools would you use to help with this recommendation? (Choose two.)
- A . Upgrade Advisor
- B . OneCollect
- C . Config Advisor
- D . Active IQ
A customer is expanding an ONTAP 9.4 switchless 2-node FAS2750 cluster. Two AFF A220 nodes will be added to the cluster.
In addition to the cluster nodes, what else is required to perform the cluster expansion?
- A . Additional management switches are required.
- B . An upgrade to ONTAP 9.5 is required.
- C . Cluster switches are required.
- D . Additional DS224C shelves are needed.
What is the recommended minimum of data LIFs per node for iSCSI in a dual-fabric configuration with four SVMs?
- A . 8
- B . 12
- C . 16
- D . 4
Click the Exhibit button.
The LUN that is shown in the exhibit is mounted by a Windows 2016 server.
In this scenario, which two statements are correct? (Choose two.)
- A . The LUN has misaligned I/O.
- B . The LUN has aligned I/O.
- C . The LUN’s space is reserved.
- D . The LUN’s space is not reserved.
A customer recently added two nodes with FC ports to a 4-node cluster.
Which SVM configuration is needed before the customer creates LUNs on the new nodes?
- A . The FC service needs to be enabled on the data SVM.
- B . The existing LIFs need to be migrated to the new nodes.
- C . New FC LIFs need to be created on the cluster SVM.
- D . New FC LIFs need to be created on the new nodes.
