Explanation: 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.

Explanation: 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.

Explanation: 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.

Explanation: According to Nutanix Support & Insights3, you need to install the Nutanix AHV plugin for Citrix Virtual Apps and Desktops on Delivery Controllers (also called the MCS plugin SDK) to create and manage Citrix-provisioned VMs in a Nutanix AHV infrastructure environment.

Explanation: ECC (Error Correcting Code) mode is a feature of some NVIDIA GPUs that provides error detection and correction for memory errors. However, ECC mode can interfere with vGPU functionality and prevent vGPU-enabled VMs from being created or started1. Therefore, two correct steps to resolve this issue are B (Disable ECC by running nvdia-smi -e 0) and D (Check if ECC Mode is turned on by running nvdia-smi -q | grep “ECC Mode” -A2).

Explanation: one of the possible causes of poor performance in a VDI deployment is power management, which can affect CPU frequency and performance. Therefore, it is recommended to disable any power saving features on the BIOS level, such as C-states and P-states.
Another possible cause of poor performance is network configuration, which can affect network throughput and latency. Therefore, it is recommended to update network drivers and firmware on the Dell XC nodes with ESXi23, and ensure that they are compatible with Nutanix software.

Explanation: 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.

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.

Explanation: 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, applicationlogs, backups, and archives1. Nutanix Files also provides high availability and a unified single namespace for easy management2.

Explanation: The schedule has two rows: one for Weekdays and one for Tuesday and Thursday.
Each row has a column for Instances, which indicates how many instances should be running during that time range.
Each row also has a column for Time Range, which indicates the start and end time for running the instances.
The time range is expressed in 24-hour format, where 00:00 means midnight and 24:00 means midnight of the next day.
According to the exhibit, the schedule Dev has the following settings:
On Weekdays (Monday to Friday), five instances are running from 09:00 am till 05:00 pm.
On Tuesday and Thursday, five instances are running from 00:00 am till 24:00 pm.

Explanation: Shadow Clones are a unique feature of the AOS storage that enables distributed caching of virtual disks (vDisks) used by virtual machines1. Shadow Clones provide effective caching optimization in distributed multireader scenarios, such as large VDI and cloud deployments2.
The warning message you see indicates that Shadow Clones are disabled on your Nutanix cluster. This may affect the performance of your Instant Clone desktop pool, as it will not benefit from the caching optimization provided by Shadow Clones.

Explanation: Writable AppVolumes are a feature of VMware App Volumes that provides users with a dedicated virtual disk for storing user profile data and user-installed applications1. Writable AppVolumes are stored as VMDK files on a datastore2. To protect Writable AppVolumes during a disaster in a Nutanix environment, one possible solution is to use asynchronous DR between two sites. Asynchronous DR allows you to replicate VMs and their associated data from one site to another at regular intervals using protection domains and remote sites3.
