NEW QUESTION 4

Exhibit.

A customer is testing a dual-fabric FC SAN configuration as shown in the exhibit and the zones are implemented on the switches shown below.

If all the nodes are in the SLM reporting nodes list, hoe many path per LUN should the customer expect when simulating an FC SFP failure by bringing LIF_3 offline?

• A. 15 paths
• B. 3 paths
• C. 4 paths

NEW QUESTION 6

Your customer asks you how to connect a host for SAN access to the newly installed AFF A400 system. In this scenario, which two statements are correct? (choose two)

• A. Direct Connection to the nodes from the hosts with ISCSI is supported
• B. Direct Connection to the nodes from the hosts with ISCSI is not supported
• C. Direct Connection to the nodes from the hosts with FC is not supported
• D. Direct Connection to the nodes from the hosts with FC is supported

Answer: AC

Explanation:
ISCSI-Direct-attachment: In a direct-attached configuration, one or more hosts are directly connected to the controllers.
You cannot directly attach FC or FC-NMVE SAN hosts to single nodes without using an FC switch. You can find more information on this link:

NEW QUESTION 7

You have a 4-node cluster with a FAS8200 HA pair and an AFF A300 HA pair. You need to migrate a LUN from a FAS8200 node to an AFF A300 node for faster performance.
Which method will non-disruptively migrate the LUN to the AFF A300 while retaining snapshots of the LUN on the FAS8200?

• A. You move the LUN.
• B. You relocate the aggregate.
• C. You move the volume.
• D. You copy the LUN.

Answer: D

NEW QUESTION 8

You are installing an AFF A250 system with ONTAP 9.8 software. Your customer asks you about the recommended LIF configuration for the ISCSI protocol. In this scenario, which two statements are correct
(choose two)

• A. Each node in an ISCSI configuration must be connected to a minimum of two ethernet switches
• B. All LIFs from the SVM are connected to a single Ethernet switch
• C. Each SVM in an ISCSI configuration must have a minimum of two LIFs per node
• D. Each SVM in an ISCSI configuration must have a minimum of one LIF per node

Answer: AC

Explanation:
It is recommended that all SVMs in ISCSI configurations have a minimum of two LIF's per node in separate Ethernet networks for redundancy and MPIO across multiple paths.

NEW QUESTION 9

You want to provision an iSCSl LUN.
Which two steps are required to accomplish this task? (Choose two.)

• A. Add the initiator IP address to the igroup.
• B. Map the LUN to the igroup.
• C. Add the target WWPN to the igroup.
• D. Add the initiator 1QN to th«t igroup.

Answer: BD

NEW QUESTION 10

Which two components must be verified for a supported NetApp SAN confutation? (Choose two.)

• A. host memory
• B. host GPU
• C. host multipath
• D. host bus adapter

Answer: CD

NEW QUESTION 11

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)

• A. Set the queue depth on the host to 8
• B. Update the HBA driver
• C. Zone the host by using the host WWNNs
• D. Use the Netapp Virtual Storage Console to configure the host settings

Answer: BD

Explanation:
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

NEW QUESTION 12

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?

• A. SCSI thick provisioned LUN
• B. SCSI thin provisioned LUN
• C. NetApp thin provisioned volume
• D. NetApp thick provisioned volume

Answer: B

Explanation:
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.

NEW QUESTION 13

You want configure namespaces to support NVMe over Fibre Channel (NVMe/FC) using ONTAP 9.8. Which action will accomplish this task?

• A. Add FC to the list of SVM protocols
• B. Remove any protocols from the SVM before adding the NVMe protocol
• C. Enable ALUA on the namespaces that should use the NVMe protocol
• D. Configure a LIF for the NVMe protocol

Answer: D

Explanation:
Although ONTAP uses a NVMe/FC LIF that is separate from the FCP LIFs, both LIFs can be hosted on the same physical HBA port at both the host initiator and storage target. NVMe/FC and FCP can
share the same physical infrastructure concurrently, so the same physical port, cable, switch port, and target port can simultaneously host and transmit both FCP and NVMe/FC frames
NVMe can use the same FC infraestructure, but it needs to create a separate NVMe LIF to work. You can find more information on this link:

NEW QUESTION 14

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 HBA.

• A. The LUN ID must be set to 0
• B. The LUN ID must be set to 255
• C. During the boot process, using FCP is not supported by Netapp
• D. During the boot process, using FCP is not supported by Microsoft

Answer: A

Explanation:
Create the LUN that you want to use as a boot device, and map it to the igroup as LUN ID 0 You can find more information on this link:
