In Nutanix Files,quotascan be configured as eithersoft limitsorhard limits:
* Soft Limit:Users receive notifications (e.g., emails) when they exceed their quota, but they arestill able to write new data.
* Hard Limit:Strict enforcement-userscannot write new databeyond the quota.
In this scenario, the HR user is getting email notifications, meaning a soft limit is currently in place. However, they can still write new data because thehard limit enforcementhas not been enabled.
The NUSA course explicitly states:
"For a quota to prevent further writes, you must enable hard limit enforcement. Otherwise, users will only receive notifications but will not be blocked from writing." Therefore, torestrict HR users from writing new data, the administrator should enablehard limit enforcementon the quota policy.

When creating a new Nutanix Objects instance viaPrism Central, Prism Central must havecompleted synchronizationwith the Prism Element cluster(s). This synchronization ensures that:
Cluster details and resources(such as available storage, network configurations, and capacity) are properly displayed in Prism Central.
Prism Central can create and manage Object Storesbased on accurate data from the registered cluster.
From the NUSA deployment module:
"After registering Prism Element clusters in Prism Central, there is an initial synchronization process that must complete before clusters appear in workflows such as object store creation." The other options:
Manual syncis not required; Prism Central automatically synchronizes after registration.
CVM restartsare not part of the normal registration or synchronization process.
Object stores can indeed be added via Prism Centralonce the sync is complete.
Therefore, the administrator shouldwait for Prism Central and Prism Element to finish synchronizing before proceeding.

Smart DR(Disaster Recovery) for Nutanix Files ensures that the file server VMs (FSVMs) at therecovery site mirror the configuration of the primary site. Specifically, it requires that:
"The number of FSVMs deployed at the recovery site mustmatchthe number of FSVMs at the primary site." The primary site has3 FSVMs.
Therefore, the recovery site must also have3 FSVMsdeployed to ensure consistency and proper operation of Smart DR for file services.

To migrate physical SQL workloads from a legacy SAN platform where hosts boot from SAN to a Nutanix environment, the administrator can useNutanix Volumesto enable booting overiSCSI. Nutanix Volumes is a block storage solution that provides iSCSI-based storage, allowing external hosts (such as physical servers) to access Nutanix storage as block devices. This is ideal for replacing SAN-based boot volumes, as it supports the same iSCSI protocol used in traditional SAN environments.
According to theNutanix Unified Storage Administration (NUSA)course, Nutanix Volumes enables external hosts to connect to Nutanix storage via iSCSI, which can be used for boot volumes or data volumes.
The course emphasizes that "Nutanix Volumes supports iSCSI boot for physical servers, making it a suitable solution for migrating workloads from legacy SAN environments to Nutanix." This allows the administrator to configure the physical SQL servers to boot from iSCSI targets provisioned on Nutanix Volumes, leveraging the Nutanix cluster's storage resources.
TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further details that Nutanix Volumes can be configured to present iSCSI LUNs to physical hosts, which can be used for both operating system boot and application data storage. For the SQL workloads, the administrator can create iSCSI targets on Nutanix Volumes, configure the physical hosts' iSCSI initiators to connect to these targets, and migrate the boot and data volumes from the legacy SAN to Nutanix.
The other options are not suitable for this task:
* Boot using PXE protocol with Nutanix Files: Nutanix Files is a file storage solution that supports SMB and NFS protocols, not PXE (Preboot Execution Environment) booting. PXE is typically used for network-based OS installation, not for booting SQL workloads or replacing SAN-based boot volumes.
* Boot using the NFS protocol with Nutanix Files: Nutanix Files supports NFS for file sharing, but NFS is not designed for booting physical servers. It is used for file-level access, not block-level access required for boot volumes.
* Boot using Nutanix Object stores: Nutanix Objects is an object storage solution designed for S3- compatible APIs, not for block or file-based booting. It is unsuitable for hosting bootable volumes or SQL workloads.
The NUSA course documentation highlights that "Nutanix Volumes provides a seamless migration path for SAN-based workloads, including boot-from-SAN configurations, by leveraging iSCSI to present storage to physical hosts." This makes it the only viable option for the described migration task.

To protect a Nutanix Objects store from a single node or two-drive failure, the cluster must be comprised of a minimum of seven nodes. Nutanix Objects uses erasure coding to provide resiliency, distributing data and parity fragments across nodes to ensure fault tolerance. To withstand a single node failure or a two-drive failure, a specific number of nodes is required to maintain data availability and rebuild capability.
TheNutanix Unified Storage Administration (NUSA)course states, "Nutanix Objects requires a minimum of seven nodes to ensure resiliency against a single node failure or a two-drive failure, using erasure coding to distribute data and parity across the cluster." This configuration typically uses an erasure coding scheme like
4+2 or 5+2 (data + parity fragments), which requires at least six nodes for data distribution and an additional node to handle failures, totaling seven nodes.
TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that "to achieve resiliency against a single node or two-drive failure in Nutanix Objects, the cluster must have at least seven nodes to support the erasure coding configuration needed for this level of fault tolerance." This ensures that even if one node fails or two drives are lost, the remaining nodes have sufficient data and parity fragments to reconstruct the lost data.
The other options are incorrect:
* Multi-cluster option must be disabled for the object store: The multi-cluster option is not relevant to resiliency within a single Nutanix Objects deployment. It pertains to managing multiple clusters, not erasure coding or fault tolerance.
* Each node in the dense node platform requires 20 or more HDDs: There is no requirement for 20 or more HDDs per node to achieve this level of resiliency. Resiliency depends on the number of nodes and erasure coding, not the number of drives per node.
* New storage container is created for the object store: While Nutanix Objects uses storage containers, creating a new container is not a requirement for enabling resiliency. Resiliency is determined by the cluster configuration and erasure coding settings.
The NUSA course documentation highlights that "a minimum of seven nodes ensures Nutanix Objects can maintain data availability and rebuild data in the event of a single node or two-drive failure, leveraging erasure coding for resiliency." References:
