Nutanix Security Guide documentation on Data-at-Rest Encryption (DARE) specifies strict hardware compatibility rules. For Hardware Encryption, the cluster must exclusively use Self-Encrypting Drives (SEDs). The documentation states that you cannot mix SEDs and non-SEDs (standard drives) within the same cluster if you intend to use hardware-based encryption.
However, Software Encryption (AOS Software Encryption) is hardware-agnostic. It uses the CPU (leveraging AES-NI instructions) to encrypt data before writing it to the disk. Software encryption supports any drive type and is the only supported method for clusters containing a mix of SEDs and standard drives.
Therefore, the administrator must use cluster-level software encryption.

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.

Comprehensive and Detailed Explanation From Exact Extract of Nutanix End User Computing documents:
According to Nutanix AHV Administration Guide regarding GPU Pass-Through:
* Hardware Binding: GPU Pass-Through (DirectPath I/O) binds a virtual machine to a specific physical PCIe device on the host. Unlike vGPU (which abstracts the hardware), passthrough creates a 1:1 dependency.
* HA Behavior: Nutanix AHV supports High Availability (HA) for GPU-enabled VMs in the sense that if a host fails, the system attempts to restart the VM on another host (Cold Migration). Option C ("Not HA-capable") is incorrect because the system attempts the restart; it does not simply abandon the VM by design.
* Failure Cause: The restart fails (the "behavior" described) because the destination host must have the exact same GPU hardware resource available (free and matching the profile/addressing). If the other nodes in the cluster do not have a free GPU of the same type, or if they are already fully utilized, the VM cannot power on, resulting in the "Insufficient GPU resources" error.

Nutanix is the only vendor that supports replication of linked clones. This means that option A is correct.

Frame is a cloud-native desktop-as-a-service platform that allows you to deliver virtual desktops and applications from any cloud. Frame supports multiple public clouds, such as AWS, Azure, GCP, and Alibaba Cloud2. You can bring your own public cloud account and use Frame to provision and manage your virtual desktops on demand.
Frame also supports Nutanix private cloud model running AHV, which is a native hypervisor for Nutanix Enterprise Cloud Platform. You can use Frame to deliver virtual desktops and applications from your own data center using Nutanix AHV clusters3. You can benefit from the simplicity, scalability, and performance of Nutanix hyperconverged infrastructure.
