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.

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.

According to the certification details1, one of the objectives is to “Configure and manage security features such as role-based access control (RBAC), SSL certificates, encryption at rest, and data protection.”

This answer seems to align with the security team’s feedback and the objective of managing security features using Nutanix technologies.

Frame is a cloud-native desktop-as-a-service platform that delivers virtual apps and desktops from multiple public clouds1. Frame allows administrators to manage various components of their cloud accounts easily from the Frame console1.

A cloud account is a logical grouping of resources that are associated with a specific cloud provider (such as AWS, Azure, or Google) and region1. A cloud account can have multiple virtual networks, master images, and instance types that can be used to create and run virtual apps and desktops1.

To configure AWS, Azure, and Google accounts within Frame, an administrator needs to go to the Cloud Accounts section of the Frame console1. There, the administrator can add new cloud accounts or edit existing ones by providing the required credentials and settings for each cloud provider12.

In Nutanix Prism Central, the Capacity Runway scenario provides details on the available capacity for the next 12 months based on the current usage pattern. This feature can help the administrator to plan and prepare the budget for the next fiscal year. The administrator can use this information to decide whether more resources need to be added to the Nutanix cluster or if the existing resources are sufficient.

https://www.nutanix.com/products/prism/prism-central

Prism Central planning tools can help you estimate the capacity runway of your cluster by considering the storage, CPU, and memory capacity. However, you need to have at least 21 days of data from a cluster to calculate the baseline runway estimates4.

an action that the administrator should take to identify the virtual desktops in the environment that are using the most resources and causing resource contention is Filter the virtual desktops by Constrained: High. Constrained is a metric that indicates how often a virtual machine is unable to get its requested CPU resources. A high value means that the virtual machine is frequently starved for CPU and may experience performance degradation. By filtering the virtual desktops by Constrained: High, the administrator can see which ones are suffering from resource contention and take appropriate actions such as migrating them to less loaded hosts or increasing their CPU allocation.

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.

Nutanix Frame allows administrators to configure capacity settings for their virtual machines (VMs) that run virtual apps and desktops.

Capacity settings include:

• Default capacity, which defines how many VMs are turned on when there is no user activity on the account. This setting helps reduce costs by turning off unused VMs.
• Active capacity, which defines how many VMs are turned on when there is user activity on the account. This setting helps improve performance by ensuring enough VMs are available for user sessions.
• Quick Publish, which defines how many VMs are updated with the latest changes when publishing a new version of an app or desktop. This setting helps speed up the publishing process by updating only a subset of VMs instead of all of them.

According to Nutanix Frame documentation1, Quick Publish value should be equal to or less than the active capacity value for each instance type.

If Quick Publish value is set higher than active capacity value, then Frame will ignore Quick Publish value and perform regular publishing instead.

Shadow Clones are a feature of the AOS storage that enables distributed caching of virtual disks (vDisks) that are read by multiple VMs on different nodes. This can improve performance and reduce network traffic in scenarios such as VDI deployments.

Therefore, if Shadow Clones were disabled, it could cause delays in the deployments of VD’ desktops, as they would have to read the vDisk from a remote node instead of a local cache.

Nutanix is the only vendor that supports replication of linked clones. This means that option A is correct. However, I cannot guarantee the accuracy or validity of this information, so please verify it with other sources before using it.

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.

 Frame utility server is a stand-alone, general purpose Windows server that can be helpful for a variety of use cases, including:

• License server: Install a network licensing manager for your software on a Frame utility server. Your production instances can then connect to this server to get the licenses.
• Backend for a client-server application: Install a database or other backend service on a Frame utility server. Your production instances can then connect to this server to run your client-server application.
• Shared file server: Install a file sharing service on a Frame utility server. Your production instances can then access shared files from this server.
• Test and develop virtual desktops: Use a Frame utility server as a sandbox environment to test and develop your virtual desktops before publishing them to your production account.

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.

Users may expect some level of personalization and consistency across their virtual desktop sessions, even if they do not save any changes1. To customize this user experience, administrators can use different solutions that manage user profiles and settings1.

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.

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.

This is because this option will allow the administrator to use Citrix Director to reset user profiles on a Nutanix Files share that provides high performance, scalability, and resilience3.

Citrix Profile Management is a solution that allows administrators to manage user profiles and settings across different devices and sessions12. Nutanix Files is a software-defined file storage solution that provides high performance and scalability for file data12. Nutanix Files supports all forms of profile management with efficient metadata caching techniques that optimize for faster VDI logon times12. Nutanix Files offers two types of shares: standard shares and distributed shares3. Standard shares are hosted on a single file server, while distributed shares are hosted on multiple file servers for load balancing and high availability3.

The Prism Citrix Cloud integration feature allows you to configure the Citrix Cloud settings in Prism Central and connect your Nutanix cluster as a resource location in Citrix Cloud4. This enables you to use Citrix Virtual Apps and Desktops service to deliver applications and desktops to your end users.

To use this feature, 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.
• You must have a valid Citrix Cloud account with access to Citrix Virtual Apps and Desktops service4.

One of the steps for configuring the Prism Citrix Cloud integration is to establish the connection to Citrix Cloud. To do this, you need to provide three pieces of information:

• Customer ID: This is a unique identifier for your Citrix Cloud account that can be found in your profile settings2.
• Client ID: This is a unique identifier for an API client that can access your Citrix Cloud account. You can create an API client in your identity and access management settings2.
• Secret Key: This is a secret string that authenticates the API client. You can generate a secret key when you create an API client2.

one of the factors that affects end-user performance in a virtual desktop environment is network latency, which is the time it takes for data packets to travel between two points on a network.

Therefore, if the company wants to optimize end-user performance, they should choose a public cloud data center location that minimizes the network latency between the end user and the data center.

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).

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.
