An administrator is tasked with upgrading an environment that is used by graphical designers.

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

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.
