gold image is a term used to describe a template for a virtual machine (VM) that contains a preconfigured operating system and applications1. A gold image can be used to create multiple session hosts that share the same configuration1. However, a gold image needs to be properly prepared before being used as a template123.

One of the steps involved in preparing a gold image is to run sysprep on the VM. Sysprep is a tool that removes system-specific data such as computer name, security identifier (SID), and driver cache from Windows23. This allows the VM to be generalized and duplicated without causing conflicts or errors23.

One of the options that can be set when running sysprep is CopyProfile. CopyProfile is a setting that determines whether the user profile settings of the built-in administrator account are copied to the default user profile2. The default user profile is used as a template for creating new user profiles on Windows2. If CopyProfile is set to True, then any changes made by the administrator account (such as desktop wallpaper, screen saver, Start menu items, etc.) will be applied to all new user profiles2.

Therefore, if users are being disconnected from their sessions consistently after 10 minutes, it could be because the gold image has some incorrect settings in the default user profile that cause session timeout or termination. To resolve this issue, one possible solution is to sysprep the gold image with CopyProfile set to True, and make sure that there are no settings in the administrator account that could affect session stability (such as power saving options or Windows Store applications)2.

This option allows you to create a custom report with the required metrics for all VMs across all clusters and send it automatically to the operations team via email4. This way, you don’t have to manually export or FTP the data every month.

The charts provided display a scenario typical of a VDI Boot Storm or login storm, characterized by a massive spike in Read IOPS (top chart) while maintaining extremely low Read I/O Latency (bottom chart).

This behavior is best described by Data Locality (specifically leveraged through a mechanism often called Shadow Clones in VDI contexts).

The Scenario: During VDI logins, hundreds or thousands of VMs simultaneously read from the same base "Golden Image" or replica disk.

The Mechanism: Nutanix Data Locality ensures that VM data is served locally from the node where the VM is running. In the specific case of multi-reader VDI workloads, the Nutanix Distributed Storage Fabric detects that the same vDisk is being read by VMs across multiple nodes. It automatically caches this vDisk (Shadow Clone) on the local SSD/RAM of every node.

The Result: As shown in the graphs, the cluster delivers very high Read IOPS because every node is serving its own VMs from local cache, preventing network congestion. Consequently, the latency remains flat and near-zero, rather than spiking as it would in a traditional centralized storage architecture where all reads traverse the network to a single controller.

According to Nutanix EUC Troubleshooting Guides:

Tool Capabilities: RDAnalyzer (Remote Display Analyzer) is the specific tool recommended to view real-time statistics regarding the Display Protocol (Blast/ICA/PCoIP), Frames Per Second (FPS), Bandwidth, Network Latency, and GPU Utilization in a single overlay window.

Why not GPUView? NVIDIA GPUView (Option D) is a deep-dive performance trace tool used for analyzing complex rendering pipelines and driver lag (DPCs/ISRs). It does not provide a live dashboard of "Network Latency" or "Bandwidth" for the display protocol, nor is it used for quick "real-time" monitoring by administrators in the same way RDAnalyzer is.

Note on Exam Key: While some older exam dumps might incorrectly flag D, RDAnalyzer is the only tool in the list that provides the protocol-specific network metrics (bandwidth/latency) requested in the scenario.
