Question 1

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 2

A customer's storage administrator Informs you about the deactivated Automatic Switchover (AUSO) feature on their MetroCluster IP environment.

What Information would you tell your customer in this scenario?

AThe AUSO feature cannot be activated due to a non-mirrored aggregate.

BThe AUSO feature is not available in Metrocluster IP installations by design.

CA faulty link automatically deactivated the AUSO feature.

DThis is a configuration failure, you can activate that feature for the customer.

Answer : B

The AUSO feature is a MetroCluster functionality that enables an automatic switchover to the surviving site in the event of a disaster that affects one site1.

The AUSO feature is only available in MetroCluster FC configurations, which use Fibre Channel (FC) switches and FC-to-SAS bridges to connect the nodes and disk shelves across sites1.

MetroCluster IP configurations, which use Ethernet switches and network adapters to connect the nodes and disk shelves across sites, do not support the AUSO feature2.

Instead, MetroCluster IP configurations use the ONTAP Mediator service, which is a software component that monitors the health and connectivity of the MetroCluster nodes and initiates a Mediator-assisted unplanned switchover when a disaster occurs3.

The Mediator-assisted unplanned switchover is similar to the AUSO feature, but it requires the ONTAP Mediator service to be configured and running on a separate host3.

Therefore, you would tell your customer that the AUSO feature is not available in MetroCluster IP installations by design, and that they need to use the ONTAP Mediator service instead for disaster recovery.Reference:

Question 3

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 4

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 5

You created a new NetApp ONTAP FlexGroup volume spanning six nodes and 12 aggregates with a total size of 4 TB. You added millions of files to the FlexGroup volume with a flat directory structure totaling 2 TB, and you receive an out of apace error message on your host.

What would cause this error?

AThe maximum number of volume constituents has been reached in the ONTAP software.

BAll constituent volumes are full.

CThe inode limit is exceeded in the ONTAP software.

DThe maxdirsize Is exceeded in the ONTAP software.

Answer : D

The maxdirsize is the maximum size of a directory in a FlexVol or FlexGroup volume. It is determined by the number of inodes allocated to the directory. If the directory contains more files than the maxdirsize can accommodate, then the ONTAP software will return an out of space error message to the host, even if the volume has enough free space.This can happen when a FlexGroup volume has a flat directory structure with millions of files, as the maxdirsize is not automatically adjusted for FlexGroup volumes12.Reference:1: FlexGroup volumes: Frequently asked questions | NetApp Documentation2: How to increase the maxdirsize of a FlexVol volume - NetApp Knowledge Base

Question 6

When an administrator tries to create a share for an existing volume named voll, the process fails with an error.

Referring to the exhibit, what Is the reason for the error?

AThe volume must have a type of DP.

BThe volume has not been mounted.

CThe CIFS service is not authenticating properly with the domain controller.

DThe CIFS service is not in workgroup mode.

Answer : B

The error message indicates that the specified path ''/vol1'' does not exist in the namespace belonging to Vserver ''svm1''. This means that the volume ''vol1'' has not been mounted to the Vserver's namespace, which is required for creating a share. The volume type, the CIFS service status, and the CIFS service mode are not relevant to the error.Reference=https://www.netapp.com/support-and-training/netapp-learning-services/certifications/support-engineer/

Question 7

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
