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.

an action that the administrator should take to enable Shadow Clones for a VMWare Horizon Solution on AHV is Connect to Prism Central and execute the cluster enable -cluster_cluster_uuid 0xxx - show_clones=true command. Shadow Clones are a feature that helps decrease read latency by creating local copies of frequently accessed data blocks on each host2. To enable Shadow Clones, the administrator needs to connect to Prism Central and run a cluster command with the appropriate parameters1.

ersistent virtual machines are those that retain all the user's personal settings, files, and customizations after each session12. Non-persistent virtual machines are those that reset to a predefined state after each session and do not save any user data12. MCS (Machine Creation Services) is a Citrix feature that allows administrators to create and manage multiple virtual machines from a single master image3. Remote Desktop Services (RDS) is a Microsoft feature that allows users to access applications or desktops hosted on a remote server4. Citrix Virtual Apps is a Citrix feature that allows users to access applications hosted on a remote server or cloud5

This is because this option will enable the administrator to add a Nutanix cluster as a new connection by installing and registering the plugin on the Delivery Controllers that manage the connection type menu.

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.
