According to the Nutanix Life Cycle Manager (LCM) guide and NVIDIA GRID Host Driver for AHV Installation Guide:

Centralized Efficiency: The most efficient method to upgrade Nutanix clusters, including those with specialized hardware like NVIDIA GPUs, is through Prism Central (PC). Prism Central acts as the unified control plane, allowing administrators to upload the LCM bundles (including NVIDIA drivers) once and apply them across registered clusters.

LCM Workflow: The administrator should log in to Prism Central, navigate to the LCM (Life Cycle Manager) page, and use the Direct Upload feature to upload the NVIDIA GRID driver tar.gz bundle. LCM then automatically handles the inventory, pre-checks, host maintenance mode, and driver installation across the nodes in the cluster.

Why not "install_host_package" (Option D)? While the install_host_package command (CLI) is a valid method for manual installation, it is considered a legacy or fallback procedure ("manual method"). It requires logging into each CVM, running commands, and manually managing host restarts, which is far less efficient than the automated orchestration provided by LCM in Prism Central.

Why not Prism Element (Option B)? While you can perform LCM updates via Prism Element (PE) for a single cluster, Prism Central is the preferred interface for "efficient" management of the environment, especially if it scales or involves multiple clusters, and is the standard direction for all Nutanix management tasks.

According to Nutanix and Microsoft best practices for Windows 11 on AHV, the operating system has significantly higher CPU overhead compared to previous versions due to mandatory security features like Virtualization-Based Security (VBS) and Hypervisor-Protected Code Integrity (HVCI).

While the minimum requirement for Windows 11 is 2 vCPUs, this configuration is often insufficient for an acceptable user experience in a VDI environment where users are running concurrent applications. Performance analysis indicates that 2 vCPUs results in high CPU Ready time and sluggishness. The recommended configuration to resolve these performance bottlenecks is to increase the CPU allocation to at least 3 vCPUs (typically 4 vCPUs is the standard "sweet spot" for Windows 11 VDI), ensuring enough compute cycles are available for both the OS overhead and user workloads.3

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. 

one of the factors that affects end-user performance in a virtual desktop environment is network latency, which is the time it takes for data packets to travel between two points on a network.

Therefore, if the company wants to optimize end-user performance, they should choose a public cloud data center location that minimizes the network latency between the end user and the data center.

The default load balancing configuration in Nutanix AHV is Balance-SLB (Source Load Balancing). This setting utilizes all available uplinks by assigning VM traffic to specific uplinks based on source MAC address hashing. To optimize bandwidth usage, the Balance-SLB algorithm periodically evaluates link utilization and may rebalance traffic by moving a VM's assignment from one uplink to another.

According to Nutanix AHV Networking documentation, this rebalancing action involves sending a gratuitous ARP (RARP) to update the physical switch. During this split-second transition, real-time sensitive traffic—such as streaming video or VoIP—may experience dropped packets or out-of-order delivery, resulting in symptoms like "hung/frozen display frames." For environments prioritizing connection consistency over aggregate bandwidth for single VMs (like VDI with streaming requirements), Active-Backup is often recommended to eliminate the potential for rebalancing interruptions. (Note: Option A is a VMware ESXi terminology, not AHV).
