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:

= 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

The error message indicates that the ONTAP Select Deploy VM cannot connect to the vCenter server due to a network issue1.

One possible cause of this issue is that the IP address of the ONTAP Select Deploy VM is conflicting with another device on the same network2.

To correct this problem, you need to change the IP address of the ONTAP Select Deploy VM to a unique and valid address that can reach the vCenter server2.

You can change the IP address of the ONTAP Select Deploy VM by using the Deploy web interface or the Deploy CLI2.

After changing the IP address, you need to restart the Deploy services and re-add the vCenter server to the inventory2.Reference:

Having an Essentials package enables you to convert to another licensing option. This is true because the Essentials package is a capacity-based licensing option that allows you to pay for Cloud Volumes ONTAP per TiB of capacity.You can switch to another capacity-based package or to a Keystone Flex Subscription at any time1.

BYOL licenses are purchased directly from NetApp.This is true because BYOL stands for Bring Your Own License, which means you need to obtain a license from NetApp before deploying Cloud Volumes ONTAP systems in any cloud provider2.

Capacity-based license packages support only single-node configurations.This is false because capacity-based license packages support both single-node and HA configurations1.

AWS Marketplace contracts cannot be mixed with BYOL.This is false because you can mix AWS Marketplace contracts with BYOL as long as the license type matches the instance type3.Reference:1: Cloud Volumes ONTAP licensing | NetApp Documentation2: Set up licensing for Cloud Volumes ONTAP in Google Cloud - NetApp3: Set up licensing for Cloud Volumes ONTAP in AWS - NetApp

The wafl.dir.size.max event occurs when a directory has reached its maximum directory size (maxdirsize) limit, which prevents new file creation in that directory. The maxdirsize is a volume-level option that can be modified using thevolume modifycommand. To solve this issue, you should increase the maximum directory size for the volume that contains the CIFS share, as long as it does not exceed 3% of the physical memory. Alternatively, you can reorganize the directory structure to avoid having too many files in one directory.Reference=
