one of the possible Nutanix storage efficiency features that the administrator can use for this solution is Deduplication. Deduplication is a technology that eliminates duplicate blocks of data and reduces storage consumption. 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 Machine Creation Services (MCS) or Provisioning Services (PVS)1.

The error message "Could not create SSL/TLS secure channel" when attempting to connect Citrix Studio to a Nutanix AHV cluster indicates a protocol mismatch between the Citrix Delivery Controller and the Nutanix Prism interface.

Nutanix AOS enforces strict TLS 1.2 security standards. To communicate effectively with the Nutanix cluster, the Citrix Delivery Controllers must have the correct version of the Nutanix AHV Plugin for Citrix installed. This plugin manages the hosting connection and ensures that the communication utilizes the required TLS 1.2 protocols and cipher suites. If the plugin is missing, outdated, or corrupted, the secure channel cannot be established, resulting in this specific error. Installing or upgrading to the latest supported plugin resolves the communication failure.

According to Nutanix AHV Best Practices for Virtual Desktop Infrastructure (VDI):

Power Management: The most critical "optimal" configuration for latency-sensitive EUC workloads is to ensure the host power management policy is set to High Performance. This prevents the CPU from entering power-saving states (C-states/P-states) which can introduce latency during user interaction.

Memory Configuration: While Nutanix AHV typically disables memory overcommit by default (or does not use it in the same way as other hypervisors for VDI), the active configuration step required by an administrator to guarantee optimal performance is the Power Management setting. Memory reservation should generally be 100% (not 50%) to avoid swapping, and CPU/Memory shares are usually left at default unless there is specific contention, but Power Management is the baseline requirement for EUC optimization.

Why not D? While memory overcommit should be disabled for VDI, in many AHV versions this is the default behavior or inherent architecture. "High performance power management" represents the specific tuning parameter that administrators must validate or configure (often in the BIOS or via AHV command) to ensure the environment is "optimized" for desktop workloads.

administrator can take to resolve the issue of performance for several full clone virtual desktops within Cluster01 by migrating them to Cluster02. 

a recovery plan is a set of steps that defines how to recover guest VMs from a disaster. A recovery plan can be used to migrate VMs between Nutanix clusters at the same or different availability zones1.

According to the "Citrix Virtual Apps and Desktops on Nutanix" best practices guide, the recommended storage container configuration depends on the provisioning method. For Citrix MCS (Machine Creation Services) Non-persistent workloads, the following settings are explicitly recommended in the Nutanix storage table:

Compression: Enabled (Inline compression is recommended for all workloads to improve capacity and performance).

Deduplication: Disabled (For non-persistent MCS, the write-heavy differencing disks are deleted upon reboot, making post-process capacity deduplication ineffective. While performance deduplication can help with reads, Nutanix Shadow Clones automatically handle caching of the base image on AHV, rendering deduplication largely redundant and an unnecessary overhead for this specific use case).

Erasure Coding: Disabled (Erasure coding is not suitable for the random write patterns and "hot" data associated with active VDI desktops; it is designed for cold, archive data).

Therefore, the correct configuration is Compression Enabled, Deduplication Disabled, and Erasure Coding Disabled.

Here are the 100% verified answers and detailed explanations based on the latest Nutanix End User Computing and Best Practices documentation.

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.

The error code displayed in the exhibit, NET::ERR_CERT_AUTHORITY_INVALID, explicitly indicates that the browser does not trust the Certificate Authority (CA) that signed the SSL certificate presented by Prism Central.

According to the Nutanix Security Guide and Prism Central documentation regarding Security Certificate Management:

By default, Nutanix clusters and Prism Central use a self-signed certificate.

When an administrator accesses Prism via a web browser using these default certificates, the browser will display a security warning (such as "Your connection is not private") because the self-signed certificate authority is not in the browser's or operating system's Trusted Root Certification Authorities store.

To resolve this behavior, the administrator must either import the self-signed root certificate into the client's trusted store or replace the default certificate with one signed by a commercial or internal CA that the browser already trusts.

If the issue were related to the hostname missing (Option C), the error code would be NET::ERR_CERT_COMMON_NAME_INVALID. Since the error is specifically "Authority Invalid," the cause is the lack of trust in the issuer (CA).
