When forecasting infrastructure requirements for a new program in a Nutanix environment where all existing applications will be decommissioned, the most straightforward method is to disregard any workload calculations that include existing applications. This ensures that the analysis focuses solely on the needs of the new program.
Option A, "Check the Disregard Existing Workloads radio button in the Runway scenario," is the correct choice. Nutanix Runway is a tool designed to help administrators forecast and plan infrastructure requirements based on upcoming needs without being skewed by current utilizations that are scheduled to be decommissioned.
This method allows for a cleaner, more accurate projection of resources needed for the new applications, disregarding any resources currently in use that will no longer be relevant.
References:This approach is detailed in Nutanix planning and forecasting documentation, ensuring administrators can plan accurately for infrastructure changes and needs without the interference of outgoing workloads.

The issue where users can mount all three storage containers despite the intention to restrict access to just container-1 typically stems from a Global whitelist entry. A global whitelist allows all entities to access all containers unless more specific restrictions are applied at the container level. To correct this, specific whitelist entries need to be configured for each container to define and restrict access appropriately.References:

Given the reported RX errors on eth2 and the intermittent ping loss as observed from the CVM logs, the best initial troubleshooting step that avoids VM disruption is to inspect the switch port for errors. Option C,
"Check the port on the switch side for any errors," is the most direct and non-invasive approach to determining if the issue lies with the network infrastructure rather than the server hardware itself or the configuration.
This action helps identify whether the problem is related to the physical connection (e.g., port issues, switch configuration errors) without altering the current active network setup on the Nutanix node. If errors are found on the switch port, adjustments or repairs can be made accordingly, potentially resolving the RX errors without impacting the running VMs.
