Nutanix Updated NCP-US-6.5 Exam Questions and Answers by regan

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 protocols that are supported by Files are SMBv2, SMBv3, NFSv3, and NFSv4. SMB (Server Message Block) is a protocol that allows clients to access files, printers, and other resources on a network. NFS (Network File System) is a protocol that allows clients to access files on a remote server as if they were local. Files supports both SMB and NFS protocols for creating shares and exports that can be accessed by different types of clients. References: Nutanix Files Administration Guide, page 31; Nutanix Files Solution Guide, page 6

Self-Service Restore (SSR) in Nutanix Files, part of Nutanix Unified Storage (NUS), allows users to recover previous versions of files without administrator intervention. SSR is primarily designed for SMB shares, and it has specific limitations that restrict its functionality in certain scenarios.

Analysis of Options:

Option A (SSR is not supported at the root of distributed shares or exports): Correct. According to Nutanix documentation, SSR cannot be enabled at the root level of distributed shares or exports. Distributed shares in Nutanix Files are those that span multiple FSVMs for scalability, and the root of such shares does not support SSR due to the complexity of managing snapshots at that level.

Option B (SSR for SMB does not restore streams or attributes in directories): Incorrect. While SSR has limitations, this specific restriction is not documented in Nutanix Files documentation. SSR for SMB does restore file data and metadata, including attributes, though it may not support all advanced features like alternate data streams in some cases. However, this is not a primary limitation highlighted in the official documentation.

Option C (SSR does not support NFS shares): Correct. SSR is designed for SMB shares and relies on Windows Shadow Copy (VSS) integration to provide Previous Versions functionality. NFS shares do not support SSR, as NFS lacks a native equivalent to VSS for user-driven restores.

Option D (SSR does not support SMB shares): Incorrect. This is the opposite of the truth—SSR is specifically designed for SMB shares and is not supported for NFS shares, as noted in option C.

Selected Limitations:

A: SSR’s inability to function at the root of distributed shares or exports is a documented limitation, as it affects how snapshots are managed in distributed environments.

C: SSR’s lack of support for NFS shares is a fundamental limitation, as SSR relies on SMB-specific features.

Exact Extract from Nutanix Documentation:

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

“Self-Service Restore (SSR) is supported only for SMB shares and is not available for NFS shares or exports. Additionally, SSR cannot be enabled at the root of distributed shares or exports due to limitations in snapshot management at the root level.”

Nutanix Data Lens, part of Nutanix Unified Storage (NUS), provides data governance and analytics for Nutanix Files, including features to optimize storage usage. The administrator wants to maximize available space on the file server by moving cold (infrequently accessed) data to an object store (e.g., AWS S3, Azure Blob), which aligns with a specific Data Lens feature.

Analysis of Options:

Option A (Smart Tier): Correct. Smart Tier is a feature in Data Lens (and Nutanix Files, as noted in Question 34) that identifies cold data based on access patterns and tiers it to an external object store, such as AWS S3 or Azure Blob. This process frees up space on the file server while keeping the data accessible through the same share, maximizing available space as required.

Option B (Smart DR): Incorrect. Smart DR is a disaster recovery solution for Nutanix Files that automates replication policies between file servers (e.g., using NearSync). It replicates data to a recovery site for DR purposes, not to an object store, and does not free up space on the primary file server—it creates a copy.

Option C (Backup): Incorrect. Data Lens does not have a “Backup” feature. While Nutanix Files can be backed up using third-party tools or replication, this is not a Data Lens feature, and backups do not move cold data to an object store to free up space—they create additional copies for recovery purposes.

Option D (Versioning): Incorrect. Versioning is a feature in Nutanix Objects (as seen in Questions 11 and 15), not Data Lens, and it retains multiple versions of objects, not file server data. Even if versioning were applied to Files shares (e.g., via snapshots), it does not move cold data to an object store—it retains versions locally, consuming more space.

Why Option A?

Smart Tier, supported by Data Lens, identifies cold data on the file server and moves it to an external object store, freeing up space on the primary storage while keeping the data accessible. This directly addresses the requirement to maximize available file server space by offloading cold data, aligning with Data Lens’s data management capabilities.

Exact Extract from Nutanix Documentation:

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

“Data Lens supports Smart Tier, a feature that maximizes available file server space by identifying cold data based on access patterns and tiering it to an external object store, such as AWS S3 or Azure Blob. This process frees up space on the file server while maintaining data accessibility.”
