Q12. An additional LUN is required to be created and attached to an existing VMware ESXi environment. You are asked by a VMware administrator what NetApp software would validate multi-path connections to a newly presented FC LUN.
In this scenario, which NetApp software is required?

You must install Active IQ OneCollect.

You must install Active IQ Config Advisor.

You must Install the DSM onto the virtual machine.

You must install the NetApp VSC.

Q13. When planning out a new FC SAN implementation for a AFF cluster, which two variables should be considered for a highly-available, resilient solution? (Choose two.)

Length of LC/LC optic cables

Multiple disk shelves

Multiple PDUs connected to separate circuits

Data-fabric zones using multiple switches

Q14. What are two benefits of implementing VLANs for ISCSI configuration? (choose two)

Reduced number of broadcast domains

Increased performance

Increased security

Increased resiliency

When you implement VLANs in large IP network infrastructures, you derive the following benefits:
Increased security.
VLANs enable you to leverage existing infrastructure while still providing enhanced security because they limit access between different nodes of an Ethernet network or an IP SAN.

Q15. 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.)

CHAP creates a hash value for the username and shared secret.

iSCSI ACLs are applied to the initiator configuration to provide an IP address of the targets.

CHAP encrypts all iSCSI session I/O.

iSCSI ACLs are applied to the target configuration to provide an IP address of the initiators.

Q16. Click the Exhibit button.

Referring to the exhibit, which two configuration elements are required to configure an SVM to support NVMe on Red Hat Enterprise Linux? (Choose two.)

Set the security style to Mixed (UNIX and NTFS).

In Data Protocols, choose both FC/FCoE and NVMe protocols.

In Data Protocols, choose only the NVMe protocol.

Set the security style to UNIX.

Q17. You are planning few a new AFF A700 2-node switchless FC solution with two Cisco 9100 switches. Each AFF A700 will have one 16 Gb port Connected to each Cisco 9100 switch and four FC LIKs per physical port. You want to guarantee recovery from connection loss on a NetApp physical port and you are using single initiator to multiple target zoning.
What is the minimum number of zones required to accomplish this task?

Q18. You have a 2-node AFF A220 switchless cluster serving iSCSI LUNs. NetApp Volume Encryption (NVE) is enabled on all data volumes. You are asked to consolidate identical boot LUNs that are on both controllers. You need to nondisruptively consolidate LUNs with the highest storage efficiency.
In this scenario, which NetApp ONTAP technology accomplishes this task?

aggregate relocate

LIF migrate

volume move

LUN move

Q19. When booting your NetApp storage system for the first time the system fails to boot.
What should you do first to address this problem?

You turn off your storage system and disk shelves, and then turn on the disk shelves. You then check the quick reference card that came with the disk shelf for information about LED responses.

You re-download the boot image to the compact flash card, then reboot the system.

You look for a description of the problem on the LCD and console. You then follow the instructions, if provided, on the LCD and console.

You verify disk shelf compatibility and check the disk shelf IDs to verify that the disk shelf 1 (for DS14 series) must be connected to your system.

Q20. You are configuring a VMware sphere host for FC access to a Netapp ONTAP cluster. In this scenario, which two tasks does Netapp recommend performing on the Vsphere host? (choose two)

Set the queue depth on the host to 8

Update the HBA driver

Zone the host by using the host WWNNs

Use the Netapp Virtual Storage Console to configure the host settings

Zoning the host using WWNNs is not recommended. Netapp always recommends to use WWPN to zone correctly.
We can not stablish a queue depth value because we don’t have the amount of ports and hosts to calculate the recommended queue depth Installing VSC and updating the HBA driver are best practices recommended by Netapp You can find more information on this link:
https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.exp-iscsi-esx-cpg%2FGUID-C751F905-04B4-4DE6-ADC4-A47EA9076078.html
https://docs.netapp.com/ontap-9/topic/com.netapp.doc.exp-fc-esx-cpg/FC%20express%20configuration%20for%20ESXi%20using%20VSC.pdf (page 7)

Q21. You are configuring both NVMe and FC on the same AFF A700 2-node ONTAP 9.5 cluster. You are also configuring both protocols on the same FC fabric using the same A700 HBA ports.
In this scenario, which three configurations are supported? (Choose three.)

16 GB HBAs

8 GB HBAs

16 GB fabrics

32 GB HBAs

32 GB fabrics

Q22. 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?

SCSI thick provisioned LUN

SCSI thin provisioned LUN

NetApp thin provisioned volume

NetApp thick provisioned volume

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.

Q23. An administrator is designing a SAN solution.
What are two considerations when completing this task? (Choose two.)

limiting the number of paths to eight paths per LUN

identifying the maximum number of paths that are supported by a host operating system

limiting the number of paths to eight paths per node

identifying the maximum number of paths that are supported by a multipath driver

Q24. Exhibit.

You need to configure the SnapCenter Plug-in for VMware vSphere to back up and restore VMware datastores.
Referring to the exhibit, which additional LIF type should you create before you configure the plug-in?

intercluster

node management

SVM management

cluster management

Q25. Which protocol provides multipathing and path management for both path and target failover for NVMe over Fibre Channel (NVMe/FC)?

Asynchronous Namespace Access (ANA)

N_Port ID virtualization (NPIV)

Asymmetric Logical Unit Access (ALUA)

NVMe namespaces

Q26. Click the Exhibit button.

You have an 8-node AFF A800 ONTAP 9.7 cluster. You have sixteen SVMs that serve NVMe namespaces using two 32 Gb FC ports per AFF A800 controller.
Referring to the exhibit, what is the maximum number of NVMe data LIFs that are supported on this cluster?

Pull an Ethernet cable from a Linux host.

Perform a storage controller failover.

Pull an Ethernet cable from a storage port with a cluster LIF.
