NCP-EUC Exam Dumps - Nutanix Certified Professional (NCP) Questions and Answers

For a Citrix VDA (Virtual Delivery Agent) to successfully register with the Delivery Controller, it must establish a secure communication channel which relies heavily on Kerberos authentication.

A common cause for registration failure on startup, particularly in new deployments or non-persistent environments, is that the Time is off on the machines. If the system clock of the virtual desktop drifts more than 5 minutes from the domain controller or the Delivery Controller, Kerberos ticket generation fails. This prevents the VDA from authenticating with the Broker Service, resulting in a "Unregistered" state in Citrix Studio. While Windows 11 has strict hardware requirements (Option A), failing to meet those usually prevents the OS from booting or installing entirely; if the OS boots but fails to register, time synchronization is the most probable infrastructure cause.

non-persistent VDI desktops are virtual desktops that do not save any changes made by the user after they log off or shut down12. They rely on a master image that contains the OS, configuration settings, and other customizations that replicate to multiple virtual desktops1.

A mandatory profile is a type of roaming profile that is read-only and does not save any changes made by users during their sessions. A mandatory profile can be applied to a group of users who share a common desktop environment and do not need to customize their settings or preferences.

A mandatory profile can ensure that a group of base settings are applied to Citrix-based VDI users at each logon, regardless of any changes they make during their sessions. A mandatory profile can also improve performance, security, and consistency of the VDI environment.

To use a mandatory profile with Citrix Virtual Apps and Desktops, you need to create a template profile on a reference machine, rename its NTUSER.DAT file to NTUSER.MAN, and copy it to a network share. Then you need to configure Profile Management policies or Active Directory settings to point to the network share location for your users2.

one of the possible causes of slower logon and application load times for VMware Horizon-based virtual desktop users is Failed to create Native clone errors. This error occurs when there is a problem with cloning virtual machines using Nutanix Native Clones technology. To troubleshoot this issue, you can check the following:

The Nutanix cluster has enough free space to create clones

The Nutanix cluster has enough CPU and memory resources to handle cloning operations

The Nutanix cluster is running a compatible version of AOS and AHV with VMware Horizon

The VMware Horizon environment is configured correctly to use Nutanix Native Clones

The VMware Horizon agent is installed and updated on the master image

Nutanix Prism Central includes Behavioral Learning and Efficiency reporting tools designed to identify inefficient resource usage.7

To verify if VMs are "using less than their configured memory" (wasted resources), the administrator should view the Over-provisioned VMs list within the Efficiency widget. Nutanix defines an "Over-provisioned VM" as one that is sized with more resources (CPU/Memory) than it actually consumes based on historical performance data.8 This list explicitly identifies these VMs, allowing the administrator to right-size them and reclaim cluster resources, whereas Task Manager (Option A) is manual/individual, and Capacity Runway (Option D) focuses on global cluster storage/resource exhaustion time rather than individual VM efficiency.

Nutanix Files is a software-defined, scale-out file storage solution that provides a repository for unstructured data, such as home directories, user profiles, departmental shares, application logs, backups, and archives1. Nutanix Files also provides high availability and a unified single namespace for easy management2.

To install the NVIDIA GRID host driver (vGPU driver) on a Nutanix AHV cluster, the administrator must upload the driver file (typically an RPM) to a Controller VM (CVM). From the CVM, the correct procedure is to use the install_host_package command.

This specific Nutanix utility pushes the installation package to the AHV hosts and executes the installation process. The typical syntax is install_host_package -r , which ensures the driver is correctly applied to the hypervisor layer across the cluster nodes. allssh or hostssh commands with standard Linux package managers (like yum) are not the supported method for applying hypervisor-level drivers in AHV.

Blast Extreme is the proprietary display protocol developed by Omnissa (formerly VMware) for Horizon.

A key feature of Blast Extreme is its use of Adaptive Transport. This technology allows the protocol to dynamically switch between UDP (for high performance and lossy networks) and TCP (as a fallback for reliability) based on real-time network conditions. This adaptability ensures the best possible user experience regardless of bandwidth or latency constraints. (PCoIP primarily relies on UDP, and RDP is traditionally TCP-heavy, while HDX is a Citrix protocol).

According to Citrix on Nutanix Best Practices for Profile Management:

Legacy Roaming Profiles: A "Legacy Roaming Profile" (Windows Roaming User Profiles) functions by downloading the entire profile (files, folders, AppData, etc.) from the network share to the local VM at logon, and uploading changes back at logoff.

Impact on Performance: If a user has a large existing profile (common in legacy migrations), this copy process creates massive network and disk I/O activity during the logon/logoff phase, resulting in extended wait times (the "Applying User Settings" or "Waiting for User Profile Service" screens).

Contrast with Modern Solutions: Modern VDI solutions use Profile Containers (like FSLogix or Citrix Profile Management containers) which mount the profile as a virtual disk (VHDX) almost instantly, rather than copying files.

Why not Home Folder (C)? A home folder is typically a mapped network drive. It does not copy data to the desktop at logon; it simply maps a pointer. Therefore, having "too much data" in a mapped drive does not slow down the logon process itself.

According to Nutanix and Microsoft Best Practices for Non-Persistent VDI images:

Policy Setting: The Group Policy setting "Allow Automatic Updates immediate installation" should be set to Disabled.

Reasoning: In a non-persistent environment, desktops revert to their base state upon reboot. Allowing automatic updates to install immediately during a user session consumes system resources (CPU/IOPS) and any changes made are discarded when the user logs off and the VM reboots.

Correct Management: Updates should be applied solely to the Master/Gold Image during a maintenance window. Once the master image is updated and sealed, it is redeployed to the pool. Disabling immediate installation prevents the "Windows Update" service from attempting to patch transient clones unnecessarily.
