Exhibit.

Dining a data mobility test on a 4-node ONTAP 9.3 cluster, the host loses direct access to its LUNs. The LUNs are hosting on node cl1-01 and are being moved to cl1-03 on a different HA pair.

Referring to the exhibit, which corrective step is needed to ensure access while the volume is moved?

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?

Which formula is appropriate for calculating target port Queue Depth?

Automatic host-side space management with SCSI T10 thin-provisioned LUNs is achieved by which feature of ONTAP?

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 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.)

You create a new iSCSI SVM and secure iSCSI sessions by using both Challenge-Handshake Authentication Protocol (CHAP) and iSCSI Access Control Lists (ACL).

In this scenario, in which two ways are you securing your iSCSI implementation? (Choose two.)

An administrator has an ONTAP cluster with SVMs and LUNs as shown in the exhibit. Hosts attempting to connect to LUNs mapped from SVM "C" are unable to see their LUNs. The hosts are not configured to connect to any other SVM.

Which action should be performed to restore multi-path connectivity to the LUNs in this scenario?

You are planning to expand a SAN-only ONTAP 9.5 cluster that consists of eight AFF A700 nodes.

In this scenario, what is the maximum number of additional AFF A700 nodes that would be added?

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 LUNs that use under 5000 IOPS are moved to a FAS8200 using the lun move command.

In this scenario, what happens to the data after the LUN is moved? (Choose two.)

An administrator is trying to configure a multiple-hop Cisco MDS switch and is receiving the error shown in the exhibit.

In this scenario, which action will solve this problem?

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?

Referring to the exhibit, what happens when you change the type for port 1a from target to initiator?

You have three Windows servers and one Linux server, each with dual-ported HBAs that are connected into a dual fabric.

In this scenario, what is the minimum number of zones that you need to create within each fabric switch?

A storage administrator needs to ensure that an ONTAP FC LUN is accessible for a remote data center. The ISL ports are reporting errors. The trunkshow command output from a Brocade switch is shown below.

You have implemented FabricPool on your AFF ASA ONTAP 9.8 Cluster. An archived database has become very active, and it requires FabricPool adjustments.

Which two steps are required to address this issue? (Choose two)

You have deployed a FAS8300 system and wait to enable SAN protocols. In this scenario, which two protocols are available to serve SAN data? (Choose two)

Referring to the exhibit, which security feature would guarantee that the host A system that is mapped to LUN XYZ on the NetApp storage system is the only host that access the LUN?

Which two requirements must be satisfied to run an Upgrade Advisor report on a Netapp All SAN Array? (choose two)

During maintenance of an AFF A250 node, you want to move the SAN LIFs that are members of a port set. In this scenario, which two statements are true? (choose two)

You have an 8-node AFF A400 ONTAP 9.8 cluster that is serving FC and ISCSI LUNs. You have three SVMs for FC and one SVM for ISCSI, each for separate VMware VSphere clusters. The VMware

clusters are on separate, non-routable, networks. You are asked to set up SnapCenter software for backups of the Virtual machine datastores. What is the minimum management LIF count that is needed to

satisfy this requirement?
