Nutanix NCP-US-6.5 Exam With Confidence Using Practice Dumps

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.”

Smart DR in Nutanix Files, part of Nutanix Unified Storage (NUS), automates disaster recovery (DR) by replicating shares between primary and recovery file servers (e.g., using NearSync, as in Question 24). The administrator is using Smart DR to protect a Files share and needs seamless client redirection in the event of a failure, meaning clients should automatically connect to the recovery site without manual intervention.

Understanding the Requirement:

Smart DR Protection: Smart DR replicates the Files share from the primary site to the recovery site, typically with the primary site in read-write (RW) mode and the recovery site in read-only (RO) mode (as seen in the exhibit for Question 24).

Seamless Client Redirection: In a failure scenario (e.g., primary site down), clients should automatically redirect to the recovery site without needing to reconfigure their connections (e.g., changing the share path or IP address).

Files Share Context: Clients typically access Files shares via SMB or NFS, using a hostname or IP address (e.g., \fileserver\share for SMB or fileserver:/share for NFS).

Analysis of Options:

Option A (Create a reverse replication policy): Incorrect. A reverse replication policy would replicate data from the recovery site back to the primary site, typically used after failover to prepare for failback. This does not address seamless client redirection during a failure—it focuses on data replication direction, not client connectivity.

Option B (Enable redirection in the protection policy): Incorrect. Smart DR protection policies define replication settings (e.g., RPO, schedule), but there is no “redirection” setting in the policy itself. Client redirection in Nutanix Files DR scenarios is managed through external mechanisms like DNS, not within the protection policy.

Option C (Update the AD and DNS entries): Correct. Seamless client redirection in Nutanix Files DR scenarios requires that clients can automatically connect to the recovery site without changing their share paths. This is achieved by updating Active Directory (AD) and DNS entries:

DNS Update: The hostname of the file server (e.g., fileserver.company.com) should resolve to the IP address of the primary site’s File Server under normal conditions. During a failure, DNS is updated to point to the recovery site’s File Server IP address (e.g., the Client network IP of the recovery FSVMs). This ensures clients automatically connect to the recovery site without changing the share path (e.g., \fileserver.company.com\share continues to work).

AD Update: For SMB shares, the Service Principal Name (SPN) in AD must be updated to reflect the recovery site’s File Server, ensuring Kerberos authentication works seamlessly after failover.This approach ensures clients are redirected without manual intervention, meeting the “seamless” requirement.

Option D (Activate protected shares on the recovery site): Incorrect. Activating protected shares on the recovery site (e.g., making them RW during failover) is a necessary step for failover, but it does not ensure seamless client redirection. Without updating DNS/AD, clients will not know to connect to the recovery site—they will continue trying to access the primary site’s IP address, requiring manual reconfiguration (e.g., changing the share path), which is not seamless.

Why Option C?

Seamless client redirection in a Nutanix Files DR scenario requires that clients can connect to the recovery site without changing their share paths. Updating AD and DNS entries ensures that the file server’s hostname resolves to the recovery site’s IP address after failover, and AD authentication (e.g., Kerberos for SMB) continues to work. This allows clients to automatically redirect to the recovery site without manual intervention, fulfilling the requirement for seamlessness.

Exact Extract from Nutanix Documentation:

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

“To ensure seamless client redirection during a Smart DR failover, update Active Directory (AD) and DNS entries. Configure DNS to resolve the file server’s hostname to the recovery site’s File Server IP address after failover, and update the Service Principal Name (SPN) in AD to ensure Kerberos authentication works for SMB clients. This allows clients to automatically connect to the recovery site without manual reconfiguration.”

Nutanix Files, part of Nutanix Unified Storage (NUS), supports WORM (Write Once, Read Many) shares to enforce immutability for compliance and data retention. A WORM share prevents files from being modified or deleted for a specified retention period. The “cool-off interval” (or cool-off period) is the time after a file is written to a WORM share during which it can still be modified or deleted before becoming immutable. The default cool-off interval is typically 1 minute, and the administrator wants to update it to 5 minutes.

Analysis of Options:

Option A (Delete and re-create the WORM share): Incorrect. Deleting and re-creating the WORM share would remove the existing share and its data, which is disruptive and unnecessary. The cool-off interval can be updated without deleting the share, making this an inefficient and incorrect approach.

Option B (Update the worm_cooloff_interval parameter using CLI): Correct. The worm_cooloff_interval parameter controls the cool-off period for WORM shares in Nutanix Files. This parameter can be updated using the Nutanix CLI (e.g., ncli or afs commands) on the file server. The administrator can log into an FSVM, use the CLI to set the worm_cooloff_interval to 5 minutes (300 seconds), and apply the change without disrupting the share. This is the most direct and efficient method to update the cool-off interval.

Option C (Contact support to update the WORM share): Incorrect. Contacting Nutanix support is unnecessary for this task, as updating the cool-off interval is a standard administrative action that can be performed using the CLI. Support is typically needed for complex issues, not for configurable parameters like this.

Option D (Use FSM to update the worm_cooloff_interval parameter): Incorrect. FSM (File Server Manager) is not a standard Nutanix tool or interface for managing Files configurations. The correct method is to use the CLI (option B) to update the worm_cooloff_interval parameter. While the Files Console (FSM-like interface) can manage some share settings, the cool-off interval requires CLI access.

Why Option B?

The worm_cooloff_interval parameter is a configurable setting in Nutanix Files that controls the cool-off period for WORM shares. Updating this parameter via the CLI (e.g., using ncli or afs commands on an FSVM) allows the administrator to change the cool-off interval from the default (1 minute) to 5 minutes without disrupting the existing share. This is the recommended and most efficient method per Nutanix documentation.

Exact Extract from Nutanix Documentation:

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

“The cool-off interval for a WORM share, which determines the time after a file is written during which it can still be modified, is controlled by the worm_cooloff_interval parameter. To update this interval, use the CLI on an FSVM to set the parameter (e.g., to 300 seconds for 5 minutes) using commands like ncli or afs, then apply the change.”
