NCP-US-6.5 Exam Dumps - Nutanix Certified Professional - Unified Storage (NCP-US) v6.5

The most likely cause for this issue is that the file server resides on a single node cluster. A distributed share is a type of SMB share or NFS export that distributes the hosting of top-level directories across multiple FSVMs, which improves load balancing and performance. A distributed share cannot be created on a single node cluster, because there is only one FSVM available. A distributed share requires at least two nodes in the cluster to distribute the directories. Therefore, the option to use distributed share/export type instead of standard is not present when creating a share on a single node cluster. References: Nutanix Files Administration Guide, page 33; Nutanix Files Solution Guide, page 8

A single-node cluster cannot support a Distributed Share because it can only host one FSVM, whereas Distributed Shares require at least three FSVMs for distribution and high availability. This limitation causes the “Use Distributed Share/Export type instead of Standard” option to be absent when creating a share, as the cluster does not meet the minimum requirements.

Exact Extract from Nutanix Documentation:

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

“Distributed Shares require a minimum of three FSVMs to ensure scalability and high availability, which typically requires a cluster with at least three nodes. On a single-node cluster, only Standard Shares are supported, and the option to create a Distributed Share will not be available in the Files Console.”

Nutanix Files, part of Nutanix Unified Storage (NUS), uses File Server Virtual Machines (FSVMs) to manage file services. High Availability (HA) in Nutanix Files ensures that shares remain accessible even if an FSVM or host fails. HA mechanisms include IP reassignment, FSVM distribution, and integration with hypervisor HA features.

Analysis of Options:

Option A (Files reassigns the IP address of the FSVM to another FSVM): Correct. In a Nutanix Files HA scenario, if an FSVM fails (e.g., due to a host failure), the IP address of the failed FSVM is reassigned to another FSVM in the file server. This ensures that clients can continue accessing shares without disruption, as the share’s endpoint (IP address) remains the same, even though the backend FSVM handling the request has changed.

Option B (Shares availability are not impacted for several minutes): Incorrect. While Nutanix Files HA minimizes downtime, there is typically a brief disruption (seconds to a minute) during an FSVM failure as the IP address is reassigned and the new FSVM takes over. The statement “not impacted for several minutes” implies a longer acceptable downtime, which is not accurate—HA aims to restore availability quickly, typically within a minute.

Option C (Multiple FSVMs can share a single host): Incorrect. Nutanix Files HA requires that FSVMs are distributed across different hosts to ensure fault tolerance. By default, one FSVM runs per host, and Nutanix uses anti-affinity rules to prevent multiple FSVMs from residing on the same host. This ensures that a single host failure does not impact multiple FSVMs, which would defeat the purpose of HA.

Option D (Affinity rules affect HA): Correct. Nutanix Files leverages hypervisor HA features (e.g., AHV HA) and uses affinity/anti-affinity rules to manage FSVM placement. Anti-affinity rules ensure that FSVMs are placed on different hosts, which is critical for HA—if multiple FSVMs were on the same host, a host failure would impact multiple FSVMs, reducing availability. These rules directly affect how HA functions in a Files deployment.

Selected Statements:

A: IP reassignment is a core HA mechanism in Nutanix Files to maintain share accessibility during FSVM failures.

D: Affinity (specifically anti-affinity) rules ensure FSVM distribution across hosts, which is essential for effective HA.

Exact Extract from Nutanix Documentation:

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

“High Availability (HA) in Nutanix Files ensures continuous share access during failures. If an FSVM fails, its IP address is reassigned to another FSVM in the file server to maintain client connectivity. Nutanix Files uses anti-affinity rules to distribute FSVMs across different hosts, ensuring that a single host failure does not impact multiple FSVMs, which is critical for HA.”

Nutanix Data Lens, a service integrated with Nutanix Unified Storage (NUS), provides data governance and security features for Nutanix Files. One of its key features is Audit Trails, which tracks user activities and file operations. The audit trails include specific details that can be monitored and reported.

Analysis of Options:

Option A (User Emails): Incorrect. Data Lens Audit Trails track user activities, but they do not specifically log user emails as an audit trail metric. User identities (e.g., usernames) are logged, but email addresses are not a standard audit trail field.

Option B (Client IPs): Correct. Data Lens Audit Trails include the client IP addresses from which file operations are performed, allowing administrators to track the source of user actions (e.g., which IP accessed or modified a file).

Option C (Files): Correct. Data Lens Audit Trails track file-level operations, such as access, modifications, deletions, and permission changes, making “Files” a key audit trail metric.

Option D (Anomalies): Incorrect. While Data Lens does detect anomalies (e.g., ransomware activity, unusual file operations), anomalies are a separate feature, not an audit trail. Audit Trails focus on logging specific user and file activities, while anomalies are derived from analyzing those activities.

Selected Audit Trails:

B: Client IPs are logged in audit trails to identify the source of file operations.

C: Files are the primary entities tracked in audit trails, with details on operations performed on them.

Exact Extract from Nutanix Documentation:

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

“Data Lens Audit Trails provide detailed logging of file operations, including the files affected, the user performing the action, and the client IP address from which the operation was initiated. This allows administrators to monitor user activities and track access patterns.”

There are two ways to manage Objects: PC (Prism Central) and API (Application Programming Interface). PC is a web-based user interface that allows administrators to create, configure, monitor, and manage Objects clusters, buckets, users, and policies. API is a set of S3-compatible REST APIs that allows applications and users to interact with Objects programmatically. API can be used to perform operations such as creating buckets, uploading objects, listing objects, downloading objects, deleting objects, and so on. References: Nutanix Objects User Guide; Nutanix Objects API Reference Guide

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

The organization uses a Nutanix Files cluster, part of Nutanix Unified Storage (NUS), for back office data, with most data classified as Cold Data (infrequently accessed). They want to free up space on the Files cluster for future growth or newer data. They have added a new node with more storage to the cluster and are already using the Public Cloud for other storage needs. The goal is to migrate Cold Data to free up space while considering the best approach.

Analysis of Options:

Option A (Set up another cluster and replicate the data with Protection Domain): Incorrect. Setting up another cluster and using a Protection Domain to replicate data is a disaster recovery (DR) strategy, not a solution for migrating Cold Data to free up space. Protection Domains are used to protect and replicate VMs or Volume Groups, not Files shares directly, and this approach would not address the goal of freeing up space on the existing Files cluster—it would simply create a copy on another cluster.

Option B (Enable Smart Tiering in Files within the Files Console): Correct. Nutanix Files supports Smart Tiering, a feature that allows data to be tiered to external storage, such as the Public Cloud (e.g., AWS S3, Azure Blob), based on access patterns. Cold Data (infrequently accessed) can be automatically tiered to the cloud, freeing up space on the Files cluster while keeping the data accessible through the same share. Since the organization is already using the Public Cloud, Smart Tiering aligns perfectly with their infrastructure and requirements.

Option C (Migrate cold data from Files to tape storage): Incorrect. Migrating data to tape storage is a manual and outdated process for archival. Nutanix Files does not have native integration with tape storage, and this approach would require significant manual effort, making it less efficient than Smart Tiering. Additionally, tape storage is not as easily accessible as cloud storage for future retrieval.

Option D (Back up the data using a third-party software and replicate to the cloud): Incorrect. While backing up data with third-party software and replicating it to the cloud is feasible, it is not the best approach for this scenario. This method would create a backup copy rather than freeing up space on the Files cluster, and it requires additional software and management overhead. Smart Tiering is a native feature that achieves the goal more efficiently by moving Cold Data to the cloud while keeping it accessible.

Why Option B?

Smart Tiering in Nutanix Files is designed for exactly this use case: moving Cold Data to a lower-cost storage tier (e.g., Public Cloud) to free up space on the primary cluster while maintaining seamless access to the data. Since the organization is already using the Public Cloud and has added a new node (which increases local capacity but doesn’t address Cold Data directly), Smart Tiering leverages their existing cloud infrastructure to offload Cold Data, freeing up space for future growth or newer data. This can be configured in the Files Console by enabling Smart Tiering and setting policies to tier Cold Data to the cloud.

Exact Extract from Nutanix Documentation:

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

“Smart Tiering in Nutanix Files allows administrators to tier Cold Data to external storage, such as AWS S3 or Azure Blob, to free up space on the primary Files cluster. This feature can be enabled in the Files Console, where policies can be configured to identify and tier infrequently accessed data while keeping it accessible through the same share.”

The administrator should prevent the Files environment and the AD Server from having such a time difference in future by using the same NTP Servers for the File environment and the AD Server. NTP (Network Time Protocol) is a protocol that synchronizes the clocks of devices on a network with a reliable time source. NTP Servers are devices that provide accurate time information to other devices on a network. By using the same NTP Servers for the File environment and the AD Server, the administrator can ensure that they have consistent and accurate time settings and avoid any synchronization issues or errors. References: Nutanix Files Administration Guide, page 32; Nutanix Files Troubleshooting Guide

Nutanix Files, part of Nutanix Unified Storage (NUS), uses File Server Virtual Machines (FSVMs) to manage file services. A four-node FSVM deployment means four FSVMs are deployed, typically one per node in a four-node cluster. Nutanix Files requires two networks for FSVMs:

Client Network: Used for client-facing communication (e.g., SMB, NFS access).

Storage Network: Used for internal communication with the Nutanix cluster’s storage pool.

Each FSVM requires one IP address on each network, as established in Question 1.

Analysis of Options:

Option A (Four available IP addresses on the Client network): Correct. In a four-node FSVM deployment, each FSVM requires one IP address on the Client network for client communication (e.g., SMB, NFS). With four FSVMs, this means four IP addresses are needed on the Client network, one for each FSVM.

Option B (Four available IP addresses on the Storage network): Correct. Each FSVM also requires one IP address on the Storage network for internal communication with the Nutanix cluster’s storage pool. For four FSVMs, this means four IP addresses are needed on the Storage network, one for each FSVM.

Option C (Five available IP addresses on the Storage network): Incorrect. Only four IP addresses are needed on the Storage network for a four-node FSVM deployment—one per FSVM. A fifth IP address is not required, as there is no additional entity (e.g., a virtual IP) needed for the Storage network in this context.

Option D (Five available IP addresses on the Client network): Incorrect. Similarly, only four IP addresses are needed on the Client network for the four FSVMs. A fifth IP address might be needed in other scenarios (e.g., a virtual IP for load balancing in some configurations), but for a standard four-node FSVM deployment, four IPs suffice, as established in Question 1.

Selected Requirements:

A: Four IP addresses on the Client network are required, one for each of the four FSVMs.

B: Four IP addresses on the Storage network are required, one for each of the four FSVMs.

Why These Requirements?

Each FSVM in a Nutanix Files deployment requires one IP address on the Client network for client access and one on the Storage network for internal storage communication. For a four-node FSVM deployment, this translates to exactly four IP addresses on each network, matching the number of FSVMs.

Exact Extract from Nutanix Documentation:

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

“A Nutanix Files deployment with four FSVMs requires four available IP addresses on the Client network for client communication (SMB/NFS) and four available IP addresses on the Storage network for internal communication with the Nutanix cluster’s storage pool.”
