NCP-US-6.10 Practice Exam Questions with Answers Nutanix Certified Professional - Unified Storage (NCP-US) v6.10 Certification

According to the Nutanix Unified Storage Administration (NUSA) course, specifically in the module “Deploying and Configuring Nutanix Objects,” theObject Store creationprocess within Prism Central depends on theregistration and access synchronizationbetween Prism Central and Prism Element. The documentation explicitly states:

“When Prism Central is first connected to a Prism Element cluster, there may be a delay of up to 15 minutes for the access control and cluster data to fully synchronize. During this time, certain cluster resources may not appear when attempting to create new object stores.”

This statement confirms that if the access was granted to Prism Elementless than 5 minutes ago, the cluster will not yet be visible in the “Cluster” drop-down list. This delay in synchronization is the reason for the empty cluster list in the interface.

Option Ais incorrect because Prism Central administrators, not just local Prism Element admins, have the authority to create object stores.

Option Bis incorrect because the delay is not tied to the 1-hour registration time, but rather the few minutes required for initial synchronization.

Option Cis incorrect because the Prism Element admin role is not a prerequisite for this task within Prism Central.

The Nutanix Unified Storage Administration (NUSA) course module “Configuring and Securing Volume Groups” specifies that to secure access to volume groups (VGs) containing sensitive data:

CHAP Authentication(Challenge-Handshake Authentication Protocol) provides an additional layer of security by requiring authentication before iSCSI connections are established. This satisfies the second requirement: “The access needs to be secured with an additional security login.”

IQN-based Access Controlensures that only the intended initiator (the client OS) can access the VG by explicitly specifying the IQN of the client in the VG configuration. This meets the first requirement: “The VG must be accessible only by the OS where the data is going to be used by the application.”

WhileOn-the-wire encryptionis beneficial for data confidentiality, the course emphasizes that CHAP and IQN-based controls are the specific mechanisms for access security.RDMA-capable NICsare not relevant to restricting access or security in this context.

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.”

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.

During Nutanix Objects deployment,Object Store instance namingis governed by specific conventions to ensure system consistency and compatibility with DNS and object storage standards.

The NUSA course describes thesestrict naming rules:

Length Rule:

“Object store names must be between 3 and 32 characters in length. This ensures that the names are concise yet descriptive enough for operational clarity.”

Start/End Rule:

“Object store names must begin with a letter and end with a letter or a number. Names cannot start with a number or symbol to maintain naming consistency across DNS and storage services.”

Uniqueness Across All Clusters:

“While object store names must be unique within the same Nutanix cluster, global uniqueness across multiple clusters is not enforced or required.”

Starting with a number:

“Names starting with numbers are not supported, as per best practices to align with DNS naming standards.”

Thus, the enforced rules:

????Minimum 3, maximum 32 characters

????Begin with a letter and end with a letter/number

The Nutanix Unified Storage Administration (NUSA) course, in the module “Configuring Metro Availability for Nutanix Files,” specifies that for zero RPO between two Nutanix Files instances, aMetro Protection Domain (Metro PD)must be enabled. This synchronous replication method ensures zero data loss (RPO = 0) and near-instantaneous failover capability between two sites with low latency.

The course states:

“For Nutanix Files running on two clusters with <5ms latency, Metro Protection Domains enable synchronous replication of Files data, ensuring zero RPO in the event of a failure.”

In Nutanix Unified Storage (specifically when using Volume Groups as iSCSI targets for VMs),IO performance scalingand redundancy acrossmultiple CVMsdepends on theiSCSI MPIO (Multi-Path I/O)feature configured within theguest OS.

According to the NUSA course:

“To leverage multiple CVMs for servicing IO requests to a volume group, MPIO must be configured in the guest operating system. MPIO allows the VM to establish multiple concurrent iSCSI sessions to the Nutanix cluster, balancing the load across available CVMs.”

Without MPIO, even if multiple CVMs host the VG target, the guest OS will typically establish asingle iSCSI sessionto one CVM at a time, limiting scalability and redundancy.

The virtual RAID controller in the guest OS (option A) has no impact on how iSCSI paths are handled at the network level.

Flash mode (option C) only affects local performance caching and does not provide multi-path IO.

Configuring multiple vDisks in a VG (option D) improves storage organization but does not automatically enable multi-path IO to different CVMs.

Thus, the administrator mustenable iSCSI MPIO in the guest OSto ensure the VM can leverage multiple CVMs for IO operations.

A requirement forSmart DR(Disaster Recovery) in Nutanix Files is thatprimary and recovery file servers must support the same protocols. Smart DR is a feature that enables automated disaster recovery for Nutanix Files by replicating file shares between a primary site and a recovery site, ensuring business continuity in case of a failure.

According to theNutanix Unified Storage Administration (NUSA)course, “Smart DR requires that the primary and recovery file servers support the same file-sharing protocols (e.g., SMB, NFS) to ensure seamless failover and consistent client access.” This ensures that clients can access the same shares with the same protocol after a failover, maintaining application compatibility and user experience.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further states that “Smart DR configurations mandate that the primary and recovery file servers are configured with identical protocol support to enable consistent replication and recovery of file shares.” For example, if the primary file server uses SMB for Windows clients, the recovery file server must also support SMB.

The other options are incorrect:

Primary and recovery file servers must have different domain names: Smart DR does not require different domain names. In fact, using the same domain name can simplify AD integration and client access during failover.

File servers may have different FSVM numbers at the primary and recovery sites: While Smart DR allows flexibility in FSVM counts, it is not a requirement. The number of FSVMs can be the same or different based on site resources, but this is not mandated.

The Files Manager must have only one file server: Nutanix Files Manager can manage multiple file servers, and Smart DR does not restrict the environment to a single file server.

The NUSA course documentation highlights that “Smart DR ensures protocol consistency between primary and recovery sites to support seamless failover, making protocol support a critical requirement for configuration.”

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.

According to the NUSA course materials,File Analyticsis designed to be deployed on thesame networkas the Nutanix Filesclient networkbecause:

File Analyticsaccesses file share metadata and analytics datathrough the same SMB/NFS protocolsused by clients accessing the shares.

Using theclient networkensures that File Analytics canconnect to the SMB/NFS endpoints, collect activity logs, and provide visibility without traversing storage-only traffic.

Using thestorage network(as was done with IP 10.1.4.100 in this case) leads to deployment errors because:

“The storage network in Nutanix Files is used exclusively for data replication and cluster-level operations—not for client or analytics traffic. Using this network for File Analytics deployment causes communication failures.”

Thus, the administrator mustredeploy File Analytics on the Files client network (10.1.3.0/24), ensuring proper access and connectivity.

The firewall port configuration (ports 445/139) is relevant for SMB traffic butnotthe root cause of the deployment error in this case.

To satisfy the configuration requirements for managing data lifecycle in Nutanix Unified Storage, the administrator shouldconfigure Lifecycle rules with enabled tiering for AWS S3 and Objects instance. Nutanix Data Lens, which integrates with Nutanix Objects and supports tiering to cloud storage like AWS S3, allows administrators to define lifecycle rules to automatically tier data to cost-effective storage based on access patterns or age.

TheNutanix Unified Storage Administration (NUSA)course explains that “Nutanix Data Lens enables lifecycle management through tiering policies that move data from Nutanix Objects to cloud storage, such as AWS S3, to optimize storage costs.” Lifecycle rules in Data Lens can be configured to tier infrequently accessed data to AWS S3, which supports tiering to storage classes like S3 Standard-Infrequent Access or S3 Glacier.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide states that “lifecycle rules in Nutanix Data Lens are used to configure tiering for Nutanix Objects, allowing data to be moved to AWS S3 for long-term storage or archival.” This applies to both Nutanix Objects and AWS S3, as Data Lens supports tiering policies for both environments to ensure efficient data placement.

The other options are incorrect:

Configure Lifecycle rule with enabled tiering for AWS S3 and replication for Objects instance: Replication is not a primary function of lifecycle rules in Nutanix Data Lens for Nutanix Objects. Replication is typically handled by other mechanisms, such as Smart DR or bucket replication, not lifecycle rules.

Configure Lifecycle rule with enabled replication for AWS S3 and tiering for Objects instance: Lifecycle rules in Data Lens focus on tiering, not replication, for Nutanix Objects. AWS S3 replication is a separate feature that is not managed through Data Lens.

Configure Lifecycle rules with enabled replication for AWS S3 and Objects instance: Lifecycle rules in Data Lens do not support replication for either AWS S3 or Nutanix Objects; they are designed for tiering.

The NUSA course documentation notes that “Nutanix Data Lens lifecycle rules enable tiering to AWS S3 and other cloud storage, ensuring data is stored cost-effectively while remaining accessible, making tiering the primary mechanism for lifecycle management.”

The issue involves Nutanix Objects stopping the collection of analytics data for Nutanix Data Lens approximately nine months after being enabled. To resume Data Lens functionality, the administrator shoulddisable and re-enable analytics on the object store. Nutanix Data Lens is a cloud-based service that provides analytics and lifecycle management for Nutanix Objects, and issues with analytics data collection can often be resolved by resetting the analytics configuration.

TheNutanix Unified Storage Administration (NUSA)course states, “If Nutanix Data Lens stops gathering analytics data for an object store, a common troubleshooting step is to disable and re-enable analytics on the object store to reset the connection and resume data collection.” This process forces the object store to re-establish its integration with Data Lens, clearing any potential configuration or connectivity issues that may have caused the analytics to stop. The nine-month period suggests a possible timeout or licensing issue with Data Lens, which can be resolved by this action.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “disabling and re-enabling analytics on a Nutanix Objects store is an effective way to troubleshoot Data Lens functionality issues, ensuring that the object store re-syncs with Data Lens for analytics data collection.” The administrator can perform this action through Prism Central by navigating to the Nutanix Objects configuration, disabling analytics for the affected object store, and then re-enabling it.

The other options are incorrect:

Rename the bucket within the object store: Renaming a bucket does not affect Data Lens integration or analytics data collection, as Data Lens operates at the object store level, not the bucket level.

Remove and re-add IAM user permissions on the object store: IAM user permissions control access to the object store but are not directly related to Data Lens analytics collection. Changing permissions is unlikely to resolve this issue.

Disable and re-enable versioning on the object store: Versioning allows multiple versions of objects to be stored but does not impact Data Lens analytics functionality.

The NUSA course documentation emphasizes that “resetting analytics by disabling and re-enabling the feature on the object store is a standard troubleshooting step to resume Data Lens functionality when analytics data collection stops unexpectedly.”

The issue involves an administrator attempting to upgrade a Nutanix Objects cluster using Prism Central’s Lifecycle Manager (LCM), but the latest version of Nutanix Objects is not listed after running an inventory, despite other components (MSP Controller, Objects Manager, Objects Services) being updated. The most likely reason is thatPrism Central is not running a compatible versionrequired to support the latest Nutanix Objects version.

TheNutanix Unified Storage Administration (NUSA)course states, “LCM upgrades for Nutanix Objects require Prism Central to be running a version that is compatible with the target Objects version; if Prism Central is not on a compatible version, the latest Objects version will not be listed in the LCM inventory.” Prism Central orchestrates LCM upgrades, and its version must support the new features, APIs, and metadata of the target Nutanix Objects version. If Prism Central is running an older version, it may not recognize or list newer versions of Nutanix Objects available for upgrade.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “a common reason for missing component versions in LCM is an incompatible Prism Central version; administrators must ensure Prism Central is upgraded to a version that supports the target Nutanix Objects release.” The guide recommends checking the Nutanix compatibility matrix to verify that the current Prism Central version supports the desired Objects version and upgrading Prism Central if necessary.

The other options are incorrect:

The administrator does not have needed permissions: The administrator has already logged into Prism Central, navigated to the LCM page, and performed an inventory, indicating sufficient permissions to view available versions. Permission issues would typically prevent access to LCM entirely.

The Objects version is not supported on-premise: Nutanix Objects is fully supported on-premise, and there is no indication that the target version is cloud-only.

The MSP Controller on Prism Element has not been updated: The MSP Controller has already been updated to the latest version as per the scenario, and the MSP Controller on Prism Element is not directly responsible for listing Objects versions in Prism Central’s LCM.

The NUSA course documentation emphasizes that “ensuring Prism Central is on a compatible version is a critical step before upgrading Nutanix Objects via LCM; an incompatible Prism Central version will prevent the latest Objects version from appearing in the inventory.”

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.

Smart Tieringin Nutanix Files is a built-in feature that allows administrators toautomatically move infrequently accessed data(cold data) tolower-cost storage tiers(like NFS or S3-compatible storage). It also supportsautomatically recalling dataif it becomes hot (frequently accessed) again.

According to NUSA course details:

“Smart Tiering policies in Nutanix Files allow administrators to define rules based on file metadata (type, size, owner) and last access time. Cold data is tiered off to cheaper storage, and Files can recall the data if needed, ensuring transparent access for users.”

Key reasons why Smart Tiering is the solution:

Automatically identifies cold data(based on access patterns).

Moves cold data to external or cheaper storagetransparently.

Re-hydrates dataautomatically if it becomes hot again, maintaining performance and user experience.

The other options:

Advanced tiering in Data Lens— Data Lens is for analytics and reporting, not for moving data.

Lifecycle Rules in Objects— manages data lifecycle for object buckets, not Files shares.

SSR (Self-Service Restore)— is for file recovery, not data tiering.

Thus, the administrator shouldconfigure Smart Tiering in Nutanix Filesto satisfy the requirement.

A single AOS cluster supports a maximum of 4 Nutanix Object Stores. Each object store is an independent instance with dedicated resources.

To receive email notifications about unusual behavior related to permission changes on corporate file shares, the administrator shoulddefine anomaly rulesin Nutanix File Analytics. File Analytics is a monitoring and analytics tool for Nutanix Files that provides visibility into file share activities, including permission changes, access patterns, and potential security threats. Anomaly rules allow administrators to detect and be notified of unusual or suspicious activities, such as unexpected permission modifications.

TheNutanix Unified Storage Administration (NUSA)course explains that File Analytics includes an anomaly detection feature that uses machine learning to identify deviations from normal behavior. The course states, “Administrators can define anomaly rules in File Analytics to monitor specific activities, such as permission changes, and configure email notifications for timely alerts.” By setting up anomaly rules, the administrator can specify criteria for permission-related events and enable email alerts to be sent when such anomalies are detected.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “File Analytics anomaly rules can be customized to track permission changes, excessive file access, or other suspicious activities, with notifications sent via email to ensure timely response.” This makes anomaly rules the most appropriate method for addressing the administrator’s requirement.

The other options are not suitable:

Create an Alert Policy: Alert policies in Nutanix are typically used for system-level events (e.g., hardware failures or cluster issues) managed through Prism Central, not for file share-specific activities like permission changes.

Configure Events Quotas: Events quotas are used to manage resource limits or thresholds, not to monitor or notify about specific activities like permission changes.

Set Ransomware Email Recipient: This option is specific to ransomware detection in File Analytics, which focuses on identifying file encryption or mass file modifications, not permission changes.

The NUSA course documentation notes that “File Analytics anomaly rules provide granular control over monitoring file share activities, with email notifications ensuring administrators are promptly informed of potential security issues like unauthorized permission changes.”

To ensure compliance with the requirement for acommon naming systemacross multiple Nutanix Objects instances, the administrator should leverage theFederated Namespacefeature, also referred to as a global namespace in Nutanix documentation. A Federated Namespace in Nutanix Objects allows multiple object store instances to share a unified namespace, enabling consistent bucket and object naming across distributed sites, which is essential for applications requiring a common naming system.

TheNutanix Unified Storage Administration (NUSA)course explains that “Nutanix Objects supports a global namespace, often referred to as a Federated Namespace, to provide a unified view of buckets across multiple object store instances, ensuring consistent naming for applications.” This feature allows applications to access objects using the same bucket names and paths, regardless of the physical location of the object store instances, meeting the requirement for a common naming system.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further states that “a Federated Namespace in Nutanix Objects ensures that multiple object store instances can share a common namespace, which is critical for applications requiring consistent naming across distributed environments.” This is particularly useful in multi-site deployments where Nutanix Objects instances need to present a unified namespace for seamless data access.

The other options are incorrect:

Multicluster: Multicluster refers to the ability to manage multiple Nutanix clusters, but it is not a feature of Nutanix Objects and does not address namespace consistency.

Streaming Replication: Streaming replication is a data replication method, typically used in other contexts like databases, and is not a feature of Nutanix Objects for namespace management.

Cloud Tiering: Cloud tiering allows data to be moved to cloud storage (e.g., AWS S3) for cost optimization but does not provide a common naming system across object store instances.

The NUSA course documentation notes that “a Federated Namespace, or global namespace, in Nutanix Objects is configured to ensure consistent bucket naming across multiple instances, enabling applications to use a common naming system as required.”

To alert the security team when more than 500 files are renamed hourly on a Nutanix Files instance at a dark site, the administrator shoulddefine an anomaly rule in File Analytics. Nutanix File Analytics is a monitoring and analytics tool for Nutanix Files that provides visibility into file share activities, including file operations like renames. Anomaly rules allow administrators to detect unusual activities and configure alerts, such as email notifications, for specific thresholds.

TheNutanix Unified Storage Administration (NUSA)course states, “File Analytics enables administrators to define anomaly rules to monitor file activities, such as file renames, and set thresholds for alerts, making it ideal for detecting unusual behavior like mass file renaming.” The administrator can create an anomaly rule to track file rename operations and set a threshold of more than 500 renames per hour, triggering an email alert to the security team when this condition is met. This functionality works in a dark site environment, as File Analytics operates locally within the Nutanix cluster and does not require Internet access.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “anomaly rules in File Analytics can be configured to monitor specific file operations, such as renames, with customizable thresholds and notification settings, ensuring timely alerts for potential security issues.” This makes File Analytics the best tool for the task, as it provides granular control over monitoring and alerting for file activities.

The other options are incorrect:

Set up Data Management Protection in Files Manager: Data Management Protection is not a feature of Nutanix Files; it may refer to backup or replication features, which do not address file rename monitoring.

Configure Nutanix Data Lens ransomware protection: Nutanix Data Lens focuses on data lifecycle management and tiering, not real-time monitoring of file operations like renames. While it has some ransomware detection capabilities, it is not designed for specific thresholds like 500 file renames per hour and requires Internet access, which is unavailable in a dark site.

Add MMC Snap-In for Nutanix Files: The MMC (Microsoft Management Console) Snap-In is used for managing Nutanix Files from a Windows system but does not provide monitoring or alerting capabilities for file rename operations.

The NUSA course documentation highlights that “File Analytics anomaly rules are the recommended solution for monitoring file operations like mass renames, providing customizable thresholds and alerts even in dark site environments.”

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.

Access Based-Enumeration (ABE)is a feature in Nutanix Files that controls whether users cansee folders and filesfor which they do not have access permissions. When ABE is enabled:

Users will only see the folders/files they are authorized to access.

Items for which they have no permissions will be hidden from view.

The NUSA course describes this feature:

“Access Based-Enumeration (ABE) ensures that users browsing a share will only see folders and files that they have permission to access, improving security and minimizing confusion.”

Thus,ABEis the precise feature for controllinguser visibilityof SMB shares based on permissions.

To protect a Nutanix Objects store from a single node or two-drive failure, the cluster must be comprised of aminimum 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.”

The administrator is attempting to upgrade Objects Manager, a component of Nutanix Objects, but notices that the upgrade option is disabled in Prism Central’s Lifecycle Manager (LCM). The most likely reason is that an **Objects Service upgrade previously failed**. Nutanix Objects consists of multiple components, including Objects Manager and Objects Service, and LCM enforces dependencies between these components during upgrades. If a prior upgrade of Objects Service failed, LCM will disable the upgrade option for Objects Manager until the issue with Objects Service is resolved.

The **Nutanix Unified Storage Administration (NUSA)** course states, “LCM may disable the upgrade option for Objects Manager if a dependency, such as Objects Service, has a failed upgrade, as Nutanix Objects components must be upgraded in a specific order to maintain system stability.” Objects Service is a core component of Nutanix Objects that handles the underlying object storage operations, while Objects Manager provides management and orchestration. A failed Objects Service upgrade can leave the system in an inconsistent state, preventing further upgrades of related components like Objects Manager until the failure is resolved.

The **Nutanix Certified Professional - Unified Storage (NCP-US)** study guide further elaborates that “a common reason for a disabled upgrade option in LCM for Objects Manager is a previous failure in upgrading Objects Service, which must be addressed by troubleshooting the failed upgrade and ensuring all dependencies are met.” The administrator should check the LCM logs for details of the failed Objects Service upgrade, resolve the issue (e.g., by addressing network connectivity, disk space, or version compatibility problems), and then retry the upgrade process.

The other options are incorrect:

- **Provided access keys are wrong**: Access keys are relevant for S3-compatible API access to Nutanix Objects buckets, not for LCM upgrades of Objects Manager.

- **Objects browser is not available**: The “Objects browser” is not a component or requirement for upgrading Objects Manager; this term may refer to the UI for browsing objects, which is unrelated to LCM upgrades.

- **Prism Element upgrade previously failed**: A failed Prism Element upgrade might affect cluster-level operations, but it is less likely to directly disable the Objects Manager upgrade option, as Objects Manager upgrades are managed through Prism Central and depend on Objects Service, not Prism Element.

The NUSA course documentation emphasizes that “a failed Objects Service upgrade is a frequent cause of disabled upgrade options for Objects Manager in LCM, requiring administrators to resolve the failure before proceeding.”

To monitor key information about a Nutanix Files deployment, such asMalicious Clients,Vulnerable Shares, and alist of potential ransomware attack attempts, the administrator must deploy theFile Analytics VMon-premises. Nutanix File Analytics is a dedicated virtual machine that provides advanced monitoring and analytics for Nutanix Files, offering insights into security-related activities, including malicious client behavior, share vulnerabilities, and ransomware detection.

TheNutanix Unified Storage Administration (NUSA)course states, “File Analytics is a VM that must be deployed on-premises to provide detailed monitoring of Nutanix Files, including identifying Malicious Clients, Vulnerable Shares, and potential ransomware attack attempts through its analytics and anomaly detection features.” File Analytics includes dashboards and widgets that specifically highlight security risks, such as the Malicious Clients list (clients exhibiting suspicious behavior), Vulnerable Shares (shares with overly permissive access), and ransomware detection (based on file activity patterns like mass encryption or renaming).

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “deploying the File Analytics VM enables administrators to monitor Nutanix Files for security threats, providing visibility into Malicious Clients, Vulnerable Shares, and ransomware attempts through its integrated analytics engine.” File Analytics runs locally within the Nutanix cluster, making it suitable for on-premises deployments and capable of operating in isolated environments like dark sites.

The other options are incorrect:

LCM dark site webserver: An LCM dark site webserver is used to host software updates for LCM in air-gapped environments but does not provide monitoring or analytics for Nutanix Files.

Prism Central: Prism Central provides centralized management and monitoring for Nutanix clusters but does not offer the specific security-focused analytics (e.g., Malicious Clients, ransomware detection) that File Analytics provides for Nutanix Files.

Data Lens: Nutanix Data Lens is a cloud-based service for data lifecycle management and analytics, primarily for Nutanix Objects and Files, but it focuses on tiering and data placement, not security monitoring like ransomware detection or malicious clients.

The NUSA course documentation emphasizes that “the File Analytics VM is the essential on-premises component for monitoring Nutanix Files, providing critical security insights such as Malicious Clients, Vulnerable Shares, and ransomware attack attempts.”

For quarantined files in Nutanix Files (via antivirus integration), administrators can:

Rescan: Re-check the file for malware.

Unquarantine: Restore the file if falsely flagged.

Delete: Permanently remove infected files to prevent risks.

Options A/B/C are invalid:

Alert (A): Not a file action; part of notification settings.

Report (B): Generates summaries but doesn’t act on files.

Reset (C): No such quarantine function.

Changing thename of a Nutanix Files clusterinvolves updating theDNS name resolutionfor its FSVMs and VIPs. When the cluster’s name changes:

The underlying IP addresses (CVMs, FSVMs, VIPs)do not change.

However,DNS entriesassociated with the old cluster namebecome outdated, causing clients (including management interfaces and file share connections) to fail to resolve the new name to the correct IP addresses.

From the NUSA course troubleshooting section:

“After renaming a Files cluster, update the DNS entries to reflect the new name. Otherwise, clients and administrators will be unable to reach the cluster resources.”

Restarting CVMs or FSVMs does not update DNS entries.

Deleting active user sessions won’t fix the DNS resolution problem.

Therefore, to resolve theunreachabilityissue, the administrator must:

????Delete old DNS entriesfor the previous cluster name.

????Add new DNS entriesmapping the new cluster name to the same IPs of the FSVMs and VIP.

This ensures that all systems can properly resolve the new cluster name and reach the Nutanix Files services.
