Frame is a cloud-based desktop-as-a-service platform that allows users to access Windows applications and desktops from any device1. A license server is a server that hosts a network licensing manager for software that requires licenses to run2. Frame supports using a utility server as a license server for Frame desktops1. A utility server is a stand-alone, general purpose Windows server that can be configured and managed from the Frame dashboard1.

The optimal storage configuration aligns the container settings with the specific I/O patterns of the workload types:

Non-Persistent Desktops: These are typically linked clones (MCS/Instant Clones) with high write churn and little data commonality in the delta disks. Compression Only is best. Deduplication adds overhead with no benefit.

Persistent Full Clones: These are full copies of the OS. Because there are hundreds of copies of the same OS files, Deduplication (Capacity or Performance tier) is highly effective at saving space. Compression is always recommended.

Therefore, creating two separate containers—one configured with Compression Only (for the non-persistent pools) and one with Compression and Deduplication (for the persistent full clone pools)—provides the best balance of performance and capacity efficiency (Option D).

To ensure high availability for distributed applications such as load-balanced web servers, Nutanix AHV allows administrators to configure Anti-Affinity rules.

An Anti-Affinity rule specifies that a group of virtual machines should never run on the same AHV host simultaneously. By applying an Anti-Affinity rule to the three web server VMs, the Acropolis Scheduler ensures they are distributed across different physical nodes in the cluster.

In the scenario described, the web servers likely resided on the same host (or the failing host held the only active instance). If Anti-Affinity rules had been configured, the other web server VMs would have been running on healthy hosts, ensuring continued user access to the VDI environment despite the single node failure.

This error is a known issue related to the Nutanix AHV Plugin for Citrix (MCS plugin) when interacting with a Nutanix cluster that has a high number of snapshots (as indicated by the 4797 count).

Older versions of the plugin utilized a JSON serializer with a default character limit (maxJsonLength). When the plugin attempts to fetch the inventory of snapshots (GetContent) to present them in the Citrix Studio wizard, the resulting JSON string exceeds this limit, causing the serialization exception and failing the catalog creation process.

The resolution, documented in Nutanix/Citrix Knowledge Base articles, is to upgrade the Nutanix AHV Plugin for Citrix to the latest version. Newer versions of the plugin handle large datasets more efficiently (often through pagination or increased limits), allowing the inventory to load successfully despite the large number of existing snapshots.

According to the Nutanix Security Guide, Cluster Lockdown is the specific security feature designed to restrict access to the cluster by disabling password-based authentication. When Cluster Lockdown is enabled, the cluster allows access only via SSH keys (RSA keys).

To meet the requirement of allowing access from "selected workstations" while "disallowing password access," the administrator must use Cluster Lockdown. By generating an SSH key pair and configuring the public key within the Cluster Lockdown settings (and removing the "Enable Remote Login with Password" option), the administrator ensures that only workstations possessing the corresponding private key can authenticate. This effectively restricts access to the specific workstations holding the keys and eliminates the risk associated with password-based logins. While IP restrictions (Option B/C) can limit the source addresses, they do not inherently disable password authentication, which is the primary requirement of the question.

Storage Efficiency features that will provide better storage efficiency and performance improvement for a mix of full clones and non-persistent desktops deployed via Citrix MCS on a three-node cluster are Compression and Deduplication. Compression is a technology that reduces the size of data blocks by removing redundant information. Deduplication is a technology that eliminates duplicate blocks of data and reduces storage consumption. Both Compression and Deduplication can be enabled on a per-container basis and can provide significant savings for Citrix virtual desktop deployments that use cloning technologies such as MCS2.

According to standard VDI image preparation best practices (including those for testing with tools like LoginVSI), the foundational step before any benchmarking can occur is to Install and patch the Operating System.

A benchmark is invalid if it is run on an incomplete or vulnerable OS. The standard workflow is:

Install OS and standard runtimes.

Patch fully (to represent a realistic production state).

Optimize (OSOT).

Option A represents the critical mandatory "Action" required to build the base image for the test.

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).

Comprehensive and Detailed Explanation From Exact Extract of Nutanix End User Computing documents:

According to the Prism Central Guide on Storage Policy Management and Precedence Rules:

Precedence Rule: Nutanix documentation explicitly states: "If you assign a category associated with a non-default storage policy to an entity and also enable the Enable 'Default-Storage' policy toggle switch, the non-default storage policy gets precedence over the default storage policy."

Explanation: The "Default-Storage" toggle acts as a fallback or baseline policy assignment (specifically linking the VM to the Storage: $Default category). However, if the administrator specifically tags the VM with a user-defined category (like DesktopVM) that has its own specific storage policy, the system honors the specific (non-default) policy over the generic default one.

Result: The "expected" settings (if the administrator expected the Default policy to override the specific one because they toggled the switch) are not applied because the specific category policy takes priority.

According to Nutanix "Security Log Configuration" and "Prism Central" best practices, configuring syslog monitoring via the Prism Central (PC) web console automatically propagates the configuration to all registered Prism Element clusters. This is designed for centralized management but violates the requirement for cluster-specific servers.

To configure a syslog server for a specific cluster without propagating the setting to other clusters, the administrator must use the Nutanix Command-Line Interface (nCLI) on the specific cluster (Prism Element). Documentation explicitly states: "Use the Nutanix command-line interface (nCLI) for syslog monitoring configuration to avoid propagating the configuration to the clusters."
