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

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

Nutanix Volumes allows physical servers to boot from a volume group that is exposed as an iSCSI target from the data services IP. To ensure high availability and load balancing, multipath I/O (MPIO) is required on the physical server. Object buckets cannot be used for booting physical servers1.

To scale out an existing Files instance, the administrator needs to add one Client IP and one Storage IP for each additional FSVM. Since the Files instance needs to expand from four FSVMs to six FSVMs, the administrator needs to add two Client IPs and two Storage IPs in total. The Client IPs are used for communication between the FSVMs and the clients, while the Storage IPs are used for communication between the FSVMs and the CVMs. Reference: Nutanix Files Administration Guide, page 28; Nutanix Files Solution Guide, page 7

Nutanix Files, part of Nutanix Unified Storage (NUS), provides file sharing services via protocols like SMB and NFS. In environments where users access SMB shares, network interruptions can cause sessions to disconnect, requiring users to manually reconnect. Nutanix Files offers a feature to mitigate this issue for SMB shares.
Analysis of Options:
* Option A (Durable File Handles): Correct. Durable File Handles is an SMB feature in Nutanix Files that allows client sessions to automatically reconnect after temporary network interruptions. When enabled, it ensures that file handles remain valid during brief disconnects, allowing the client to resume the session without manual intervention.
* Option B (Multi-Protocol Shares): Incorrect. Multi-Protocol Shares allow a share to be accessed via both SMB and NFS, but this feature does not address session reconnection during network issues.
* Option C (Connected Shares): Incorrect. "Connected Shares" is not a feature in Nutanix Files. This appears to be a made-up term and does not apply to session reconnection.
* Option D (Workload Optimization): Incorrect. Workload Optimization in Nutanix Files involves adjusting the number of FSVMs or resources for performance (as noted in Question 13), but it does not address session reconnection for network issues.
Why Durable File Handles?
Durable File Handles is an SMB 2.1+ feature supported by Nutanix Files. It ensures that file handles persist during network disruptions, allowing clients to auto-reconnect without losing their session state, which directly addresses the users' complaint.

From the Nutanix Files Administration Guide (available on the Nutanix Portal):
"Durable File Handles is an SMB feature that allows clients to automatically reconnect to a share after temporary network interruptions. When enabled on a Nutanix Files share, it ensures that file handles remain valid, preventing users from having to manually reconnect during brief network outages."
