You have an existing 8-node Netapp Cluster serving NFS data, and you want to expand your cluster by an additional four nodes to serve ISCSI. In this scenario, where would you validate this configuration?

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.

What are two benefits of implementing VLANs for ISCSI configuration? (choose two)

An administrator enabled the FCP protocol on an SVM and created a boot LUN for a Windows Server 2019 server host. The host is attached using multiple paths to the storage SVM. After correctly adding

the LUN to the igroup and setting its LUN ID to 1, the host is unable to boot using the installed FC HB

A.  

Which two components should be installed to support VMware VMFS6 datastores in an environment with only Ethernet switches? (Choose two)

You have a 100GB volume with the space guarantee set to volume, This volume contains two space reserved 20 GB LUNs. Both LUNs are at 50% use. You then create a snapshot copy of the volume. No

modifications were performed since the snapshot copy was completed, and all actions were performed using the CLI. In this scenario, how much free space does the volume have?

You have a two node Netapp ONTAP cluster that is hosting FC LUNs for 90 SAN hosts. The hosts are experiencing occasional performance problems and receiving QFULL responses from the cluster

nodes. Which action would solve this issue?

You are a system administrator and responsible for a Netapp AFF A800 2-node ONTAP 9.8 cluster that is used only for SAN. Your SAN uses FC and FCoE on the same Cisco switches. You want to add

NVMe from the ONTAP controller to the same Cisco fabric. Which two statements are correct in this scenario? (choose two)

You created a LUN in a new volume on your Netapp ONTAP cluster. You enabled the default snapshot schedule and enabled snapshot autodelete on the volume. In this scenario, in which three situations

does the snapshot autodelete feature automatically delete snapshot copies in the volume? (choose three)

You want to perform online data migration using Foreign LUN Import. In this scenario, which two conditions are required to support this task? (choose two)

A storage administrator created a LUN using two ports on a storage system. Later, additional LUNs were added to the same node as the original LUN. After a while, the performance of the original LUN dropped beyond an acceptable level.

What would you advise to remedy the Issue?

A customer's Red Hat Linux 7.0 server's Linux native DM-MP settings for multi pa thing have not been set correctly. In this scenario, what would cause this problem?

An administrator is planning a hardware refresh and data migration from a Data ONTAP 7.3 system to new AFF A3-00 cluster that is using ONTAP 9.0. The Mode system only serves FC LUNs to a Windows 2012Rs server cluster that needs to remain connected after migration Referring to the scenario, which method would be used for the LUN migration.

You recently bought a FAS8200 series with SAS drives and want to maximize data efficiencies. Performance is not a primary Which two statements are correct in this scenario? (Choose two.)

Exhibit.

Referring to the exhibit, what is the total amount of space that is guaranteed for the LUNs in the /vo1/vo1_sanlunsiprod_03 volume?

When booting your NetApp storage system for the first time the system fails to boot.

What should you do first to address this problem?

A customer wants to use both Cisco FC and FCoE switches in their ONTAP environment. According to NetApp best practices, what are two requirements in this scenario? (Choose two.)

Exhibit.

Referring to the exhibit, which two statements are true? (Choose two.)

Which statement is correct regarding virtual machine alignment on VMware ESX?

Exhibit.

Referring to the exhibit, which FC LIF would cause a path failure on a host connecting to a LUN?

A customer experiences intermittent connectivity problems between an ESXi server and FC LUNs in an SVM. The customer has examined the nodes hosting the LUNs and both the disk and CPU performance are below 50% utilization. The customer examined the switch ports connected to the storage array, and they ate also below 50% utilization.

Which two steps would you perform next in this scenario? (Choose two.)

Exhibit.

Referring to the exhibit. What are two viable scenarios to test LUN multipathing on Host 1?

(Choose two.)

Referring to the exhibit, which two elements are required for NVMe host access with ONTAP 9.5 and using supported AFF nodes? (Choose two.)

Referring to the exhibit, you have SAN LUNs on an AFF A700s and are asked to test an SSD shelf stack failure.

What is the maximum allowed number of failed paths per controller to shelf stack before a storage failover occurs?

You want to create an additional SVM from the System Manager GUI to serve data only using block-based protocols. You know the SVM name, the aggregate containing the root volume, and the required protocols.

What other information is required to successfully create this SVM?

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?

You create a 20 GB LUN in a newly created 100 GB FlexVol volume. You then write 5 GB of data to the LUN. You have space reservation disabled on the LUN.

In this scenario, how much space do you have left on the volume?

An administrator wants to design an NVMe solution to connect Linux hosts to an ONTAP cluster. The proposed solution uses two Cisco MDS 9396T switches for each fabric in a top-of-rack design.

In this scenario, which statement is true?

A customer is planning to connect a Linux server to a FAS8200 using Brocade FC switches. During the initial configuration, the SVM does not log in to the fabric.

Which two statements are correct in this scenario? (Choose two.)

You have an SVM that serves LUNs to your hosts in an FC SAN environment. This SVM runs on a 4-node cluster and has two data LIFs on each node, according to best practices. You just created a LUN and mapped it to your initiators group. The LUN is owned by node01.

In this scenario, what would be an appropriate test for LUN mobility?

Which two are supported in ONTAP 9.5? (Choose two.)

The ESX host reports inconsistent performance for iSCSI-based connectivity.

In this scenario, what would cause this problem?

You configured a SAN host with a 4-node ONTAP 9.5 cluster that uses default settings. All paths are available from the host to the four nodes. You have a requirement to see only two paths to each LUN. One path is optimized and the other is non-optimized.

In this scenario, which NetApp SAN feature supports this requirement?
