Free Practice Questions for Nutanix NCP-US-6.5 Exam

Nutanix Objects, part of Nutanix Unified Storage (NUS), is deployed as Object Store Service VMs on a Nutanix cluster. Expanding an Objects store cluster involves adding more resources (e.g., nodes, Object Store Service VMs) to handle increased demand. Prior to expansion, the environment must meet certain prerequisites to ensure a successful installation.

Analysis of Options:

Option A (Configure NTP on only Prism Central): Incorrect. Network Time Protocol (NTP) synchronization is critical for Nutanix clusters, but it must be configured on both Prism Central and Prism Element (the cluster) to ensure consistent time across all components, including Object Store Service VMs. Configuring NTP on only Prism Central is insufficient and can lead to time synchronization issues during expansion.

Option B (Upgrade MSP to 2.0 or later): Incorrect. MSP (Microservices Platform) is a Nutanix component used for certain services, but it is not directly related to Nutanix Objects expansion. Objects relies on AOS and Prism versions, not MSP, and there is no specific MSP version requirement mentioned in Objects documentation for expansion.

Option C (Upgrade Prism Element to 5.20 or later): Correct. Nutanix Objects has specific version requirements for AOS (which runs on Prism Element) to support features and ensure compatibility during expansion. According to Nutanix documentation, AOS 5.20 or later is recommended for Objects deployments and expansions, as it includes stability improvements, bug fixes, and support for newer Objects features. Upgrading Prism Element to 5.20 or later ensures the environment is properly configured for a successful Objects store cluster expansion.

Option D (Configure DNS on only Prism Element): Incorrect. DNS configuration is important for name resolution in a Nutanix environment, but it must be configured for both Prism Element and Prism Central, as well as for the Object Store Service VMs. Configuring DNS on only Prism Element is insufficient, as Objects expansion requires proper name resolution across all components, including Prism Central for management.

Why Option C?

Expanding a Nutanix Objects store cluster requires the underlying AOS version (managed via Prism Element) to meet minimum requirements for compatibility and stability. AOS 5.20 or later includes necessary updates for Objects, making this upgrade a critical prerequisite to ensure the environment is properly configured for expansion. Other options, like NTP and DNS, are also important but require broader configuration, and MSP is not relevant in this context.

Exact Extract from Nutanix Documentation:

From the Nutanix Objects Administration Guide (available on the Nutanix Portal):

“Before expanding a Nutanix Objects store cluster, ensure that the environment meets the minimum requirements. Upgrade Prism Element to AOS 5.20 or later to ensure compatibility, stability, and support for Objects expansion features.”

Nutanix Volumes uses IQN-based authorization to control access to volumes. The administrator must specify the IQN of the host that needs to access the volume when creating or editing the volume. If the host’s IQN is not authorized, it will not be able to see the target in the MS iSCSI Initiator3. References: Nutanix Volumes Administration Guide3

Nutanix Objects, part of Nutanix Unified Storage (NUS), supports lifecycle policies to manage the retention and expiration of objects in a bucket. When versioning is enabled, a bucket can store multiple versions of an object, with the “current version” being the latest version and “past versions” being older iterations. The lifecycle policy “Expire current objects after # days/months/years” specifically targets the current version of an object.

Analysis of Options:

Option A (The policy deletes any past versions of the object after the specified time and does not delete any current version of the object): Incorrect. The “Expire current objects” policy targets the current version, not past versions. A separate lifecycle rule (e.g., “Expire non-current versions”) would be needed to delete past versions.

Option B (The policy deletes the current version of the object after the specified time and does not delete any past versions of the object): Correct. The “Expire current objects” policy deletes the current version of an object after the specified time period (e.g., # days/months/years). Since versioning is enabled, past versions are not affected by this policy and remain in the bucket unless a separate rule targets them.

Option C (The policy does not delete the current version of the object after the specified time and does not delete any past versions of the object): Incorrect. The policy explicitly states that it expires (deletes) the current version after the specified time, so this option contradicts the policy’s purpose.

Option D (The policy deletes any past versions of the object after the specified time and deletes any current version of the object): Incorrect. The “Expire current objects” policy does not target past versions—it only deletes the current version after the specified time.

Why Option B?

When versioning is enabled, the lifecycle policy “Expire current objects after # days/months/years” applies only to the current version of the object. After the specified time, the current version is deleted, and the most recent past version becomes the new current version (if no new uploads occur). Past versions are not deleted unless a separate lifecycle rule (e.g., for non-current versions) is applied.

Exact Extract from Nutanix Documentation:

From the Nutanix Objects Administration Guide (available on the Nutanix Portal):

“When versioning is enabled on a bucket, the lifecycle policy ‘Expire current objects after # days/months/years’ deletes the current version of an object after the specified time period. Past versions of the object are not affected by this policy and will remain in the bucket unless a separate lifecycle rule is applied to expire non-current versions.”

The Nutanix-enabled technology that meets these requirements is Objects – WORM with versioning. WORM (Write-Once Read-Many) is a feature that prevents anyone from modifying or deleting data in a bucket while the policy is active. WORM policies help comply with strict data retention regulations that mandate how long specific data must be stored. Versioning is a feature that keeps multiple versions of an object in a bucket whenever it is overwritten or deleted. Versioning policies help preserve previous versions of an object for backup or recovery purposes. By enabling WORM and versioning for an Objects bucket, the administrator can ensure that data is kept for two years without being deleted or overwritten. References: Nutanix Objects User Guide, page 17; Nutanix Objects Solution Guide, page 9

Nutanix Files allows users to restore their files from the snapshots taken by the protection policy. A protection policy is a set of rules that defines how often snapshots are taken, how long they are retained, and where they are replicated. A protection policy can be applied to one or more file shares. To enable users to restore their files without administrator intervention, the administrator must enable the Self Service Restore option for each share in the Files Console. This option adds a hidden folder named .snapshot in each share, which contains all the snapshots taken by the protection policy. Users can access this folder and browse the snapshots to find and restore their files. The administrator can also configure the permissions and quota for the .snapshot folder. References: Nutanix Files Administration Guide, page 75; Nutanix Files Self-Service Restore Guide

Nutanix Files, part of Nutanix Unified Storage (NUS), provides a Self-Service Restore (SSR) feature that allows end users to recover their files without administrator intervention. This feature is particularly useful for SMB shares, enabling users to access previous versions of files or folders directly from their Windows clients (e.g., via the "Previous Versions" tab in File Explorer).

The most efficient way to enable Self-Service Restore for multiple Files shares is to configure it at the share level within the Files Console. According to the Nutanix Files Administration Guide, the Self-Service Restore option can be enabled for each share individually through the Shares tab in the Files Console. While this requires enabling the setting for each share, it is the most direct and supported method for enabling SSR across multiple shares, as it does not involve external tools like Data Lens or complex configurations like Protection Policies or Consistency Groups.

Option A: Correct. Enabling Self-Service Restore in the Edit wizard for each share via the Shares tab in the Files Console is the standard method. It allows users to restore files directly without administrator intervention. While it requires configuring each share individually, it is efficient for a small to moderate number of shares and aligns with Nutanix’s recommended approach.

Option B: Incorrect. Nutanix Data Lens is a service for data governance, analytics, and ransomware protection, not for managing Self-Service Restore settings. Data Lens focuses on scanning shares for anomalies and providing recovery points, but it does not have a direct option to enable SSR for shares.

Option C: Incorrect. Assigning Categories to FSVMs and linking them to a Protection Policy in Prism Central is related to VM or resource protection (e.g., snapshots or replication), not to enabling user-driven file restoration for Files shares.

Option D: Incorrect. Consistency Groups and Protection Domains in Prism Element are used for data protection and disaster recovery (e.g., asynchronous replication), not for enabling Self-Service Restore for end users.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“Self-Service Restore allows end users to recover files and folders from SMB shares without administrator intervention. To enable Self-Service Restore, navigate to the Shares tab in the Files Console, select a share, and click Edit. In the Edit wizard, check the ‘Enable Self Service Restore’ option. This must be configured for each share individually.”

Additional Notes:

While enabling SSR for each share individually (option A) may seem less efficient for a very large number of shares, Nutanix does not currently provide a bulk configuration option for SSR in the Files Console. Automation via APIs could be an alternative for large-scale deployments, but this is not mentioned in the question’s options.

The question emphasizes “most efficient,” and option A is the most straightforward and officially supported method per the documentation.

Nutanix Volumes, part of Nutanix Unified Storage (NUS), provides block storage services via iSCSI to external hosts, such as physical servers. The iSCSI traffic is managed by the Controller VMs (CVMs) in the Nutanix cluster, and a virtual IP address called the Data Services IP is used for iSCSI communication. To isolate iSCSI traffic on a dedicated network, the administrator must ensure that this traffic is routed over the isolated network.

Analysis of Options:

Option A (Create a new network interface on the CVMs via ncli): Incorrect. While it’s possible to create additional network interfaces on CVMs using the ncli command-line tool, this is not the recommended or standard method for isolating iSCSI traffic. The Data Services IP is the primary mechanism for managing iSCSI traffic, and it can be assigned to an isolated network without creating new interfaces on each CVM.

Option B (Configure the Data Services IP on an isolated network): Correct. The Data Services IP (also known as the iSCSI Data Services IP) is a cluster-wide virtual IP used for iSCSI traffic. By configuring the Data Services IP to use an IP address on the isolated network (e.g., a specific VLAN or subnet dedicated to iSCSI), the administrator ensures that all iSCSI traffic is routed over that network, meeting the requirement for isolation. This configuration is done in Prism Element under the cluster’s iSCSI settings.

Option C (Configure network segmentation for Volumes): Incorrect. Network segmentation in Nutanix typically refers to isolating traffic using VLANs or separate subnets, which is indirectly achieved by configuring the Data Services IP (option B). However, “network segmentation for Volumes” is not a specific feature or configuration step in Nutanix; the correct approach is to assign the Data Services IP to the isolated network, which inherently segments the traffic.

Option D (Create a Volumes network in Prism Central): Incorrect. Prism Central is used for centralized management of multiple clusters, but the configuration of iSCSI traffic (e.g., the Data Services IP) is performed at the cluster level in Prism Element, not Prism Central. There is no concept of a “Volumes network” in Prism Central for this purpose.

Why Option B?

The Data Services IP is the key configuration for iSCSI traffic in a Nutanix cluster. By assigning this IP to an isolated network (e.g., a dedicated VLAN or subnet), the administrator ensures that all iSCSI traffic is routed over that network, achieving the required isolation. This is a standard and recommended approach in Nutanix for isolating iSCSI traffic.

Exact Extract from Nutanix Documentation:

From the Nutanix Volumes Administration Guide (available on the Nutanix Portal):

“To isolate iSCSI traffic on a dedicated network, configure the Data Services IP with an IP address on the isolated network. This ensures that all iSCSI traffic between external hosts and the Nutanix cluster is routed over the specified network, providing network isolation as required.”

The cause of this issue is that the connection to Active Directory has not been configured. Active Directory is a service that provides centralized authentication and authorization for Windows-based clients and servers. To create a share that will provide user access via SMB and NFS, the administrator must first configure the connection to Active Directory in the Files Console. This will allow the administrator to enable multiprotocol accounts for NFS clients, which are accounts that map NFS users to SMB users and groups for consistent access control across both protocols. References: Nutanix Files Administration Guide, page 32; Nutanix Files Solution Guide, page 6

The action that is required to allow the deletion of file server audit data in Data Lens is to update the data retention period. Data retention period is a setting that defines how long Data Lens keeps the file server audit data in its database. Data Lens collects and stores various metadata and statistics from file servers, such as file name, file type, file size, file owner, file operation, file access time, etc. Data Lens uses this data to generate reports and dashboards for file analytics and anomaly detection. The administrator can update the data retention period for each file server in Data Lens to control how long the audit data is kept before being deleted. References: Nutanix Files Administration Guide, page 98; Nutanix Data Lens User Guide

Audit data in Data Lens is managed by a retention period, after which the data is automatically deleted. To allow deletion of audit data (e.g., to free up space or comply with policies), the administrator must update the retention period to a shorter duration, triggering the deletion of data that exceeds the new period. This is the standard method for managing audit data lifecycle in Data Lens.

Exact Extract from Nutanix Documentation:

From the Nutanix Data Lens Administration Guide (available on the Nutanix Portal):

“Audit data in Data Lens is retained for a configurable retention period. To allow the deletion of file server audit data, update the data retention period in the Data Lens console or Prism Central settings. Reducing the retention period will cause older audit data to be deleted once it exceeds the new period.”

Smart Tiering in Nutanix Files, part of Nutanix Unified Storage (NUS), allows infrequently accessed (Cold) data to be tiered to external storage, such as a public cloud (e.g., AWS S3, Azure Blob), to free up space on the primary cluster (as noted in Question 34). Configuring Smart Tiering requires setting up a connection to the external storage target, which involves providing credentials and connectivity details.

Smart Tiering requires a connection to an external storage target, such as a cloud provider. The access key and secret key are mandatory to authenticate Nutanix Files with the target (e.g., an S3 bucket), enabling secure data tiering. Without these credentials, the tiering configuration cannot be completed, making them a mandatory criterion.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“To configure Smart Tiering in Nutanix Files, you must provide the access key and secret key for the external storage target (e.g., AWS S3, Azure Blob). These credentials are mandatory to authenticate with the cloud provider and enable data tiering to the specified target.”

The Marketing department needs to recover files in a Nutanix Files share with a recovery window of 14 days. Nutanix Files, part of Nutanix Unified Storage (NUS), supports file recovery through Self-Service Restore (SSR) for SMB shares, which relies on snapshots to provide previous versions of files.

Analysis of Options:

Option A (Change default settings in the Protection Configuration window): Incorrect. The “Protection Configuration window” is not a specific feature in Nutanix Files. This may be a vague reference to snapshot policies, but the correct terminology is Protection Domain or snapshot schedules, as in option B.

Option B (Change the Protection Domain settings to keep at least 14 days of snapshots): Correct. Nutanix Files uses snapshots to enable file recovery via SSR. These snapshots are managed through Protection Domains (or snapshot schedules in newer terminology) in Prism Element or Prism Central. To ensure files can be restored within a 14-day timeframe, the snapshot retention policy must be configured to retain snapshots for at least 14 days.

Option C (Install Nutanix Guest Tools on clients who need to perform Self-Service Restore): Incorrect. Nutanix Guest Tools (NGT) is used for VM management features (e.g., VSS snapshots for backups, VM mobility), but it is not required for Self-Service Restore in Nutanix Files. SSR is a client-side feature for SMB shares that works natively with Windows clients (via the Previous Versions tab) and does not require NGT.

Option D (Enable Self-Service Restore at the share level): Correct. Self-Service Restore (SSR) must be enabled at the share level in Nutanix Files to allow users to recover files without administrator intervention. This feature enables the Marketing department to restore files directly from their Windows clients using the Previous Versions feature, provided snapshots are available (as configured in option B).

Selected Configurations:

B: Configuring the snapshot retention to at least 14 days ensures that previous versions of files are available for recovery within the required timeframe.

D: Enabling SSR at the share level allows the Marketing department to perform the recovery themselves, meeting the requirement for user-driven file recovery.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“Self-Service Restore (SSR) allows users to recover previous versions of files in SMB shares. To enable SSR, it must be activated at the share level in the Files Console. SSR relies on snapshots to provide previous versions; ensure that snapshot schedules (via Protection Domains or snapshot policies) are configured to retain snapshots for the desired recovery period, such as 14 days.”
