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.)
Correct answers: A, D
You are designing a new 4-node AFF A400 SAN cluster with 20 ISCSI hosts. Each AFF A400 node will have four data LIFs. Each ISCSI host needs to access every LUN over two LIFs per node on every SAN node.
In this scenario, which Netapp SAN feature enable this connectivity?
Correct answer: A
SLM will choose 4 LIFs per node, being 8 LIF total (owner and HA partner), enabling portsets will help to limit the ports per node... that way we can stablish only 2 LIF per node. Creating port sets and binding igroups to port sets In addition to using Selective LUN Map (SLM), you can create a port set and bind the port set to an igroup to further limit which LIFs can be used by an initiator to access a LUN. If you do not bind a port set to an igroup, then all of the initiators in the igroup can access mapped LUNs through all of the LIFs on the node owning the LUN and the owning node's HA partner.

You have a SAN host that is only sending traffic to an ONTAP cluster using active non-optimized paths.
In this scenario, over which network type does the node that is hosting the target LUN receive the traffic?
Correct answer: B
The Cluster Network
This is used for traffic that is going between the nodes themselves, such as system information that is being replicated between the nodes. Also, if incoming client data traffic hits a network port on a different controller than the one which owns the disks, that traffic will also go over the cluster network.
Which tool collects configuration data from hosts and switches to assist in evaluating a qualified configuration?
Correct answer: D
Which path selection policy is used by Windows Servers using NetApp LUNs that are greater than 2 TB?
Correct answer: C
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.)
Correct answers: B, D
What is the supported NVMe OS multipathing stack for VMware ESXi?

An administrator is asked to provision a SAN environment in which host applications can monitor LUN space and performance space reclamation.
Which LUN type would satisfy these requirements?
Correct answer: B
Automatic host-side space management with SCSI thinly provisioned LUNs If your host supports SCSI thin provisioning, you can enable the space-allocation option in ONTAP to turn on automatic host-side space management.

A customer has a 4-node cluster consisting of a FAS8020 system and an AFF A220 that is running ISCSI workloads across two separate SVMs. The FAS8020 system is reaching end of support, so they add a new AFF A400 system to migrate workloads off the FAS8020 system. The customer wants to migrate data off the FAS8020 aggregate n1_aggr1 on SVM2 to the AFF A400 aggregate n5_aggr1 on SVM1.
Correct answer: B
Moving a Volume will only work if you are doing it within the same SVM Volume Reallocation is used when you add new disks to an aggregate and you need to redistribute the data Aggregate Reallocation can be used only when you are moving data from an AFF filer to another AFF filer
Rehosting a volume from one SVM to another SVM Volume rehost enables you to reassign NAS or SAN volumes from one storage virtual machine (SVM, formerly known as Vserver) to another SVM without requiring a SnapMirror copy. The volume rehost procedures depend upon the protocol type and the volume type. Volume rehost is a disruptive operation for data access and volume management.

You are testing iSCSI LUN failover across a 4-node FAS9000 fabric-attached MetroCluster configuration.
In this scenario, which front end configuration is required for non-disruptive host LUN failover between sites?
Correct answer: A
