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

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 Files, part of Nutanix Unified Storage (NUS), provides file shares (e.g., SMB, NFS) that clients access. Intermittent server-side networking issues or FSVM High Availability (HA) events (e.g., an FSVM failover, as discussed in Question 40) can disrupt client connections. The administrator needs a feature to ensure automatic reconnection to shares during such events, minimizing disruption for users.

Analysis of Options:

Option A (Multi-Protocol Shares): Incorrect. Multi-Protocol Shares allow a share to be accessed via both SMB and NFS (as in Questions 8 and 60), but this feature does not address client reconnection during networking issues or FSVM HA events—it focuses on protocol support, not connection resilience.

Option B (Connected Shares): Incorrect. “Connected Shares” is not a recognized feature in Nutanix Files. It appears to be a made-up term and does not apply to automatic client reconnection.

Option C (Durable File Handles): Correct. Durable File Handles is an SMB feature in Nutanix Files (as noted in Question 19) that ensures automatic client reconnection after temporary server-side disruptions, such as networking issues or FSVM HA events (e.g., failover when an FSVM’s IP is reassigned, as in Question 40). When enabled, Durable File Handles allow SMB clients to maintain their session state and automatically reconnect without user intervention, meeting the requirement.

Option D (Persistent File Handles): Incorrect. “Persistent File Handles” is not a standard feature in Nutanix Files. It may be confused with Durable File Handles (option C), which is the correct term for this SMB capability. Persistent File Handles is not a recognized Nutanix feature.

Why Option C?

Durable File Handles is an SMB 2.1+ feature supported by Nutanix Files that ensures clients can automatically reconnect to shares after server-side disruptions, such as intermittent networking issues or FSVM HA events (e.g., failover). This feature maintains the client’s session state, allowing seamless reconnection without manual intervention, directly addressing the administrator’s requirement.

The configuration that is required for an Objects deployment is to configure NTP servers on both Prism Element and Prism Central. 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. Configuring NTP servers on both Prism Element and Prism Central is required for an Objects deployment, because it ensures that the time settings are consistent and accurate across the Nutanix cluster and the Objects cluster, which can prevent any synchronization issues or errors. References: Nutanix Objects User Guide, page 9; Nutanix Objects Deployment Guide
