Question 1

Your customer mentions that they have accidentally destroyed both root aggregates in their two-node cluster.

In this scenario, what are two actions that must be performed? (Choose two.)

ARejoin the second node to the re-created cluster.

BRe-create the cluster from the local backup.

CInstall ONTAP from a USB device.

DRe-create the cluster from the remote backup.

Answer : A, C

If both root aggregates are destroyed in a two-node cluster, the cluster will be inoperable and the data will be inaccessible. To recover from this situation, you need to perform the following actions:

Install ONTAP from a USB device on one of the nodes. This will create a new root aggregate and a new cluster on that node.

Rejoin the second node to the re-created cluster. This will also create a new root aggregate on the second node and synchronize it with the first node.

Restore the cluster configuration and data from a backup, if available.Reference=

Question 2

You want to assign storage access to an NVMe protocol host.

Which three objects must be configured to accomplish this task? (Choose three.)

Athe NVMe subsystem

Bthe NVMe broadcast domain

Can NVMe LIF

Dthe NVMe namespace

Ean NVMe LUN

Answer : A, C, D

To assign storage access to an NVMe protocol host, you need to configure the following objects:

TheNVMe subsystem, which is a logical entity that represents a group of NVMe namespaces that can be accessed by one or more hosts1.

AnNVMe LIF, which is a logical interface that provides network connectivity for the NVMe subsystem2.

TheNVMe namespace, which is a logical volume that is exposed to the host as an NVMe device1.

You do not need to configure the NVMe broadcast domain or the NVMe LUN, as these are not relevant for NVMe protocol host access.Reference=1:Configuring NVMe-oF - Hitachi Vantara Knowledge2:Basic VMware NVMe Architecture and Components

Question 3

You recently discovered the error message shown below in your ONTAP logs.

What should be your first action to correct this Issue?

APower cycle all the disk storage shelves that contain drives of the aggregate with the my_data_vol volume.

BDetermine the root cause behind the inconsistency before attempting any recovery procedure.

CUse the storage takeover command on the storage controller that contains my_data_vol.

DUse the wafliron command against my_data_vol to solve the inconsistency on the volume.

Answer : B

= The error message indicates that the volume my_data_vol is WAFL inconsistent, which means that there is a discrepancy between the data blocks and the metadata in the file system. This can be caused by various factors, such as hardware failures, software bugs, power outages, or network disruptions.The first action to correct this issue is to determine the root cause behind the inconsistency before attempting any recovery procedure, as recommended by the NetApp documentation1. This is because some recovery procedures, such as wafliron or storage takeover, may not work or may cause further damage if the underlying cause is not resolved. For example, if the inconsistency is due to a faulty disk or shelf, running wafliron may not fix the problem and may even corrupt more data.Therefore, it is important to identify and isolate the cause of the inconsistency before taking any further steps.Reference=1Volume Showing WAFL Inconsistent - NetApp Knowledge Base

Question 4

Recently, a CIFS SVM was deployed and is working. The customer wants to use the Dynamic DNS (DDNS) capability available in NetApp ONTAP to easily advertise both data UFs to their clients. Currently. DNS is only responding with one data LIF. DDNS is enabled on the domain controllers.

Referring to the exhibit, which two actions should be performed to enable DDNS updates to work? (Choose two.)

ADisable the -vserver-fqdn parameter for the SVM DDNS services.

BRemove the NFS protocol from the cifs_01 data LIF.

CEnable the -use-secure parameter for the SVM DDNS services.

DEnable the -is-enabled parameter for the SVM DDNS services

Answer : B, D

To enable DDNS updates to work, two actions should be performed:

Remove the NFS protocol from the cifs_01 data LIF.This is because DDNS updates are only supported for LIFs that have only one data protocol enabled1. The cifs_01 LIF has both NFS and CIFS protocols enabled, which prevents it from registering its DNS record dynamically. By removing the NFS protocol from the cifs_01 LIF, it will become eligible for DDNS updates.

Enable the -is-enabled parameter for the SVM DDNS services.This is because the -is-enabled parameter controls whether the SVM sends DDNS updates to the DNS servers2. The exhibit shows that the -is-enabled parameter is set to false for the svm1 SVM, which means that it does not send any DDNS updates. By enabling the -is-enabled parameter, the SVM will start sending DDNS updates for its eligible LIFs.Reference:

Question 5

Refer to the exhibit.

Referring to the exhibit, what do you need to do to return the MetroCluster to a normal state?

AEnter the metroclustor switchback command on Site B.

BEnter the metrocluster switchback command on Site A.

CEnter the storage failover giveback command on Site B.

DEnter the storage failover giveback command on Site A.

Answer : B

The question refers to a MetroCluster configuration, which is a disaster recovery solution that uses two physically separated, mirrored clusters1.

The exhibit shows a MetroCluster switchover scenario, where Site A has experienced a disaster and Site B has taken over the tasks of Site A2.

To return the MetroCluster to a normal state, you need to perform a MetroCluster switchback operation, which reverses the switchover and activates the original sync-source storage virtual machines (SVMs) on Site A3.

To perform a MetroCluster switchback, you need to enter themetrocluster switchbackcommand on the cluster that was the source of the switchover, which is Site A in this case3.

The other options are not correct, because:

A)Entering themetrocluster switchbackcommand on Site B will not work, as Site B is the destination of the switchover, not the source3.

C)Entering thestorage failover givebackcommand on Site B will not work, as this command is used for local HA failover within a cluster, not for MetroCluster switchover between clusters4.

D)Entering thestorage failover givebackcommand on Site A will not work, as this command is used for local HA failover within a cluster, not for MetroCluster switchover between clusters4.Reference:

Question 6

Your customer is running a NetApp AFF A800 system with NetApp ONTAP 9.8 software and states that their NS224 shelf is not showing with the correct shelf ID. You analyze the data and the shelf shows an identification of ''1.SHFHUXXXXXXXXXX."

What is the cause of the reported Issue?

AThe shelf has been power cycled.

BA new shelf was added to the controller.

CThe shelf had a disk replaced too quickly.

DThe shelf was cabled Incorrectly.

Answer : D

According to the NetApp Knowledge Base, adding a second NS224 shelf to an existing stack can cause the first shelf ID to change to the serial number if the cables are not connected properly1.This can also result in a Medium Impact error message: Shelves with both connections via the same SAS path detected2. This situation is not normal for a NetApp AFF A800 system and can affect performance and availability.The cables should be reconnected according to the SAS cabling rules and concepts for shelves with IOM12/IOM12B modules3and the controller-to-stack cabling worksheet template for quad-pathed connectivity4.Reference=Shelves with both connections via the same SAS path detected,Adding a second NS224 shelf, changes first shelf ID to the serial number,SAS cabling rules and concepts - shelves with IOM12/IOM12B modules,Controller-to-stack cabling worksheet template for quad-pathed connectivity.

Question 7

Your customer Informs you about SnapMlrror problems after upgrading NetApp ONTAP software to a newer version. After investigating the event logs and the SnapMirror history, you see information about delayed updates of the SnapMirror relationships.

How would your customer prevent such problems in the future?

AQuiesce the SnapMirror relationships before upgrading the ONTAP software.

BVerify that the cabling of the hardware port that Is responsible for SnapMirror transfers Is correct.

CModify the schedules of the SnapMirror relationships after upgrading the ONTAP software.

DDelete the SnapMirror relationships and create them new after upgrading the ONTAP software.

Answer : A

Quiescing the SnapMirror relationships before upgrading the ONTAP software ensures that the data replication is completed and consistent across the source and destination volumes. This prevents any data loss or corruption due to the upgrade process. Quiescing also suspends the scheduled updates until the relationships are resumed, avoiding any delays or failures in the transfers. The other options are not effective in preventing the SnapMirror problems after the upgrade.Reference= https://docs.netapp.com/us-en/ontap/upgrade/concept_upgrade_requirements_for_snapmirror.html
