When deploying Nutanix File servers, the correct minimum configurations include:

The minimum number of FSVMs is three(Option C).

A minimum of 12 GiB of memory per FSVM(Option D).

Nutanix Files is a scale-out file storage solution that uses File Server Virtual Machines (FSVMs) to provide file services via SMB and NFS protocols. The minimum configuration ensures high availability, performance, and scalability.

According to theNutanix Unified Storage Administration (NUSA)course, “Nutanix Files requires a minimum of three FSVMs to ensure high availability and load balancing across the file server.” This minimum of three FSVMs allows Nutanix Files to distribute file share operations and provide failover capabilities in case of FSVM or node failures.

The course also specifies that “each FSVM requires a minimum of 12 GiB of memory to handle file server operations effectively.” This memory allocation supports the processing needs of file services, including protocol handling, caching, and management tasks.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide elaborates that “Nutanix Files deployment requires at least three FSVMs, each configured with a minimum of 12 GiB of memory and four vCPUs, to meet the baseline requirements for production environments.” While the guide mentions four vCPUs as the minimum, the options provided in the question include eight vCPUs, which is not the minimum but a possible configuration for higher workloads.

The other options are incorrect:

The number of CVMs must be equal to or greater than the number of FSVMs: There is no strict requirement that the number of Controller VMs (CVMs) must match or exceed the number of FSVMs. CVMs manage the Nutanix cluster’s storage and services, and their count depends on the cluster size, not the number of FSVMs.

A minimum of eight vCPUs per FSVM: The minimum requirement is four vCPUs per FSVM, as specified in Nutanix documentation. Eight vCPUs may be used for larger deployments but is not the minimum.

The NUSA course documentation confirms that “a Nutanix Files deployment must include at least three FSVMs with 12 GiB of memory each to ensure a robust and highly available file storage solution.”

The Nutanix Unified Storage Administration (NUSA) course, in the module “Configuring Volume Groups for External Clients,” highlights that when configuring iSCSI boot for external (bare-metal) clients, the“Use DHCP for iSCSI Target Information”option must be enabled. This allows the iSCSI boot firmware (iBFT) to automatically discover the iSCSI target (Volume Group) using DHCP-provided parameters.

The course documentation states:

“Enabling ‘Use DHCP for iSCSI Target Information’ is essential for booting external clients from Nutanix Volumes using iSCSI. DHCP provides the iSCSI target IP and other relevant data for a successful boot.”

According to the official Nutanix Unified Storage Administration (NUSA) course documentation, NFS-enabled buckets in Nutanix Objects support access via standard NFS clients, including the Windows NFS client. This compatibility allows Windows systems to interact with Objects buckets using the NFS protocol for read/write operations.

However, the following capabilities are not supported with NFS-enabled buckets due to inherent limitations in object storage semantics and NFS protocol constraints:

Rename directories (Option A): Renaming directories is unsupported because it requires atomic renaming of all objects under the directory prefix, which object storage does not allow.

Hard links (Option B): Hard links violate object storage immutability and are disallowed.

Symbolic links (Option D): Symbolic links are not supported, as they conflict with object storage's flat namespace design.

Smart DR(Disaster Recovery) for Nutanix Files ensures that the file server VMs (FSVMs) at therecovery sitemirror 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.

In Nutanix Objects,bucket management permissionsare granularly controlled. TheEdit Bucketspermission allows a user tomodify bucket configurations(such as policy changes, tagging, and settings), but it doesnotgrant the ability todeletethe bucket.

From the NUSA training:

“The Delete Buckets permission is separate from Edit Buckets. Users with Edit Buckets can change configurations but cannot remove the bucket itself.”

Thus, the user’s inability to delete buckets stems fromlacking the explicit Delete Buckets permission.

FSVMs (File Server VMs)are essential for delivering file services (SMB/NFS) in Nutanix Files. Each FSVM is responsible for handling client connections and file access requests.Stopping an FSVMcan temporarily disrupt file share access if not properly coordinated.

TheHigh Availability (HA) stateis thecritical factorto check before stopping an FSVM because:

TheNUSA and NCP-US coursesemphasize:

“In a Nutanix Files deployment, High Availability (HA) for FSVMs ensures that client connections are redistributed to other FSVMs in the cluster when an FSVM is stopped or fails. Before stopping an FSVM, administrators must confirm that HA is enabled to avoid data access disruption.”

If HA is disabled or misconfigured:

Stopping an FSVM could lead toclient disconnectionsand potential data access issues.

Thefiles servicemay temporarily becomeunavailablefor the workloads handled by that FSVM.

The other options are not directly related tostopping FSVMs:

Data Protection status— more relevant to snapshots and replication, not FSVM runtime status.

VDI Sync— relates to desktop sync, not FSVM management.

SSR (Self-Service Restore)— depends on file share snapshots, not FSVM status.

Thus, the best practice is tocheck HA stateto ensure a seamless failover and minimal service impact before stopping the FSVM.

When deploying Nutanix Files, the client network requiresone additional IP address than the number of File Server Virtual Machines (FSVMs). Nutanix Files uses a distributed architecture where each FSVM handles file services for clients via protocols like SMB or NFS. The client network is used for client-facing traffic, and it requires one IP address per FSVM plus an additional virtual IP address (VIP) that serves as the primary access point for clients.

According to theNutanix Unified Storage Administration (NUSA)course, “Nutanix Files requires one IP address per FSVM on the client network for client communication, plus one additional VIP that provides a unified endpoint for accessing file shares.” The VIP is load-balanced across the FSVMs, ensuring high availability and seamless client access even if an FSVM fails.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further clarifies that “the client network for Nutanix Files must be configured with one IP address for each FSVM and an additional VIP, resulting in a total of N+1 IP addresses, where N is the number of FSVMs.” For example, a deployment with three FSVMs requires four IP addresses: three for the FSVMs and one for the VIP.

The other options are incorrect:

The same number of IP addresses as the number of FSVM nodes: This does not account for the additional VIP required for client access, which is essential for load balancing and failover.

One less IP address as the number of FSVMs: This is not feasible, as each FSVM requires its own IP address, and the VIP adds an additional requirement.

Twice as many IP addresses as the number of FSVMs: This overestimates the IP address needs, as only one additional VIP is required, not double the number of FSVMs.

The NUSA course documentation emphasizes that “the client network VIP simplifies client access to Nutanix Files by providing a single IP address that abstracts the underlying FSVMs, requiring one additional IP address beyond the FSVM count.”

Nutanix Files includes several features for managing data availability and mobility across sites. Here’s the detailed breakdown:

Data Sync— This feature is designed toreplicate user data between file servers at different locations. It enablesbi-directional or one-way file-level replicationfor use cases such as:

Branch office file sharing

Geo-dispersed data access

Centralized backups of branch data

From the NUSA course materials:

“Data Sync provides file-level replication across geographically distributed Nutanix Files deployments, ensuring consistent data access and synchronization across multiple sites.”

This feature is purpose-built forcross-location file data replication, meeting the administrator’s need.

Data Protection— Refers to snapshot-based local or remote protection of theentire file server or shares, not file-level sync across different locations.

Smart Sync— Specific to Object data within Nutanix Objects, not for Files.

VDI Sync— Designed for syncing user profiles in VDI environments, not general file share replication.

Thus, the administrator should useData Syncfor replicating user data across file servers in different locations.

The issue involves a user on an Ubuntu client (a Linux-based system) who is unable to create files on a Nutanix Files share configured to support both Windows and Linux clients. Since Ubuntu typically uses the NFS protocol to access file shares, the problem is likely related to the NFS configuration on the Nutanix Files share. The correct action is tomodify NFS Client Access to read-write, as the current setting may be restricting the Ubuntu client to read-only access.

TheNutanix Unified Storage Administration (NUSA)course explains that “Nutanix Files supports NFS for Linux clients, and administrators can configure NFS Client Access settings to control permissions, such as read-only or read-write access, for specific clients or subnets.” If the NFS Client Access is set to read-only for the Ubuntu client’s IP or subnet, the user would be able to read files but not create or modify them, which matches the described issue.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further states that “troubleshooting access issues for Linux clients on Nutanix Files often involves verifying the NFS Client Access settings, ensuring that the client has read-write permissions to create or modify files on NFS shares.” The administrator should check the NFS export settings for the share and update the client access rules to grant read-write permissions to the Ubuntu client’s IP address or subnet.

The other options are incorrect:

Allow simultaneous read access to same files: This setting is relevant for managing concurrent access to files (e.g., in SMB environments) but does not address the Ubuntu client’s inability to create files via NFS.

Update the blocked file types in the file server: Blocked file types prevent specific file extensions from being stored, but the issue is about creating files, not a specific file type being blocked.

Add NTFS permissions for the user account: NTFS permissions are relevant for SMB shares used by Windows clients, not for NFS shares accessed by Linux clients like Ubuntu.

The NUSA course documentation emphasizes that “for Linux clients experiencing permission issues on NFS shares, administrators should review and modify the NFS Client Access settings to ensure read-write permissions are granted, resolving issues like the inability to create files.”

Lifecycle Policiesin Nutanix Objects allow administrators toautomate data tiering and archivalbased on specific criteria, including object tagging. According to the NUSA training:

“A Lifecycle Policy, combined with a Cloud Bucket Endpoint, enables automatic movement of objects (based on tags) to a remote Nutanix Objects instance or compatible S3 storage.”

Here’s the detailed process:

The administrator first configures aCloud Bucket Endpointto establish connectivity to theremote Nutanix Objects instance.

Then, they create aLifecycle Policythat targets objects with specific tags for tiering.

This policy ensures that onlytagged objectsmeeting the policy’s criteria are moved to the remote storage location.

Enabling WORM on the bucket is not required for tiering; WORM is forimmutability. Thekey mechanismfor tiering tagged objects is:

????Cloud Bucket Endpoint + Lifecycle Policy for tagged objects.
