Question 1

Refer to the exhibit.

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



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 2

You are attempting to connect a NetApp ONTAP cluster to a very complex network that requires LIFs to fail over across subnets.

How would you accomplish this task?



Answer : C

A LIF (Logical Interface) is a logical entity that represents a network connection point on a node1.

A VIP LIF (Virtual IP LIF) is a LIF that can fail over across subnets within an IPspace2.

BGP (Border Gateway Protocol) is a routing protocol that enables VIP LIFs to advertise their IP addresses to external routers and to update the routing tables when a failover occurs3.

To connect a NetApp ONTAP cluster to a complex network that requires LIFs to fail over across subnets, you need to configure VIP LIFs using BGP on the cluster and on the external routers3.

This way, you can ensure that the network traffic is routed to the optimal node and port for each VIP LIF, and that the network connectivity is maintained in the event of a node or port failure3.Reference:

Question 3

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?



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 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.)



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:

2: Manage DNS/DDNS services with System Manager4


Question 5

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

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



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 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?



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?



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
