Free Practice Questions for Nutanix NCP-EUC Exam

non-persistent VDI is a type of virtual desktop infrastructure (VDI) that does not save any changes made by the user on the virtual machine (VM) across sessions. Non-persistent VDI uses a master image to create and delete VMs as needed.

Therefore, if the administrator needs to manage a non-persistent deployment, they should avoid any requirements that involve modifying or installing applications on the VMs, as those changes would not be saved.

The file server VM (FSVM) is a virtual machine that runs on Nutanix Files and provides file services such as SMB shares and NFS exports. The FSVM is based on CentOS and incorporates all the security and hardening that goes into the Nutanix Controller VM (CVM)2. The CVM is a virtual machine that runs on each node of a Nutanix cluster and provides storage management, data protection, cluster coordination, and other services3.

The FSVMs have some default configuration settings that can be changed depending on your workload requirements. For example, you can change the number of vCPUs, RAM, network interfaces, or disk size of an FSVM2. However, you should not change these settings without consulting Nutanix Support first.

One of the factors that affects the performance of an FSVM is its memory allocation. The more memory an FSVM has, the more cache it can use for file operations. This can improve the throughput and latency of file serving workloads4. Therefore, increasing the FSVM RAM to 96GB can help optimize its performance for a large number of users.

AHV Xi PC plug-in is used for when Prism Central resides in Xi Cloud. Prism Central is a management plane that provides centralized control and visibility across multiple Nutanix clusters and clouds. Xi Cloud is a hybrid cloud platform that enables customers to run their applications and workloads on Nutanix infrastructure in public cloud environments such as AWS and Azure2. The AHV Xi PC plug-in allows customers to use Citrix Virtual Apps and Desktops with Nutanix AHV clusters running on Xi Cloud3.

persistent virtual desktops are virtual desktops that retain their state and configuration across sessions.

This means that users can customize their virtual desktops with their own applications, settings, and data, and have them available every time they log on.

Persistent virtual desktops are suitable for users who need a consistent and personalized experience, such as developers.

According to Nutanix best practices2, one of the recommended migration paths for persistent virtual desktops is to convert the physical computers to virtual desktops.

This can be done by using a tool such as VMware Converter or Microsoft Disk2vhd to create a virtual disk image of the physical computer’s hard drive.

Then, this image can be imported into Nutanix Cloud Platform and used as a base image for creating persistent virtual desktops.

This migration path can preserve the existing applications, settings, and data of the physical computers and minimize the disruption for the users.

The Citrix Optimizer tool is used to prepare Windows operating system images for use in a virtual desktop environment. Some of the actions that it takes to improve the gold image creation process include:

Optimizes user environments for better performance: The tool removes unnecessary or redundant services, features, and applications from the image, which can improve performance and reduce resource usage.

Uses built-in templates to perform optimizations: The tool comes with pre-configured templates that are optimized for specific environments, such as virtualdesktops or server workloads. These templates can be customized based on the specific needs of the organization.

non-persistent VDI machines are deleted when they are rebooted, logged off, or shut down. Therefore, Windows Update policy should be configured to prevent automatic updates that may trigger a restart on these machines1.

The Nutanix AHV MCS Plug-in is a tool that enables Citrix Virtual Apps and Desktops Delivery Controllers (also called Brokers) to create and manage Citrix-provisioned VMs in a Nutanix AHV infrastructure environment. The plug-in is based on the Citrix-defined plug-in framework2.

To install the Nutanix AHV MCS Plug-in, you need to meet some prerequisites, such as:

The Delivery Controller version must be 7.15 LTSR CU3 or later.

The Delivery Controller must be able to communicate with Prism Element (PE) using HTTPS port 9440.

The Delivery Controller must have PowerShell 5.1 or later installed.

The user running the installer must have administrator privileges on the Delivery Controller2.

The Prism Central Playbook Action is a tool that allows you to automate tasks based on triggers, such as events, alerts, or webhooks. You can define a series of actions (called a playbook) that perform operations on your infrastructure, such as adding or reducing resources on a VM2.

To use the Playbook Action for VMs, you need to meet some prerequisites, such as:

The Prism Central version must be 2020.11 or later.

The AOS version must be 5.15 LTSR or later.

The hypervisor must be AHV or ESXi.

The VMs must have Nutanix Guest Tools (NGT) installed and enabled3.

One of the possible reasons why the Playbook Action is no longer being triggered is that the virtual desktop CPU Usage alerts were not cleared. According to the Prism Central guide3, “If an alert has been triggered once and has not been cleared yet, then it will not trigger any action again until it has been cleared”. Therefore, if the CPU Usage alert remains active for a virtual desktop, it will prevent the Playbook Action from adding more vCPUs to it.

Nutanix Frame has several session settings that can affect the user experience and resource utilization. One of these settings is Max session duration, which defines how long a user can stay connected to a Frame session before it is automatically terminated1. If this setting is too low, users might experience random disconnections and lose their applications and files.Therefore, the configuration setting that must be modified in order to resolve this issue is A (Max session duration).
