After an onsite cluster deployment, the As-Built Guide is a crucial document that provides detailed information about the final configuration of the system. However, certain data in the As-Built Guide might require adjustment or might be missing completely.

In this case, the Nutanix Node Port Layout (Option A) and the Physical Rack Layout (Option C) are two data that might require adjustment or might be missing completely. The Nutanix Node Port Layout provides a visual representation of the network connections for each node in the cluster, while the Physical Rack Layout provides a visual representation of the physical arrangement of the nodes in the rack. Both of these data are crucial for understanding the physical and network configuration of the cluster, and any inaccuracies or omissions in these data could lead to confusion or issues in the future.

Therefore, the consultant should ensure that the Nutanix Node Port Layout and the Physical Rack Layout in the As-Built Guide are accurate and complete.

As the consultant concludes the project, to assist the customer with repeating the deployment process at a dark site, the best items to deliver would be:

• A trial license activation code for Prism Starter, which will allow the customer to begin using the Nutanix cluster immediately without initial extra costs.
• Creating an account for access to the Nutanix Support Portal, ensuring the customer can access support and documentation as needed for troubleshooting and learning.
• A guide for dark site deployments using Nutanix standards, which will provide step-by-step instructions tailored to the specific challenges of deploying in a location with no direct internet connectivity.These resources are critical for enabling the customer to independently deploy and manage Nutanix clusters under the unique constraints of a dark site.References: Nutanix Deployment Guide, Nutanix Support Portal Documentation.

In the scenario where a consultant observes ping timeouts after shutting down one of the links during a port failover test, the issue is likely due to a Native VLAN mismatch on the switchport. The configuration settings shown in the second exhibit indicate different native VLANs for the switch ports connected to the Nutanix node. This mismatch can cause connectivity issues when one of the links is down, as VLAN tagging inconsistencies prevent proper fallback and routing of traffic.References: Cisco Networking Troubleshooting Guide, Nutanix Network Configuration Best Practices.

When using the Foundation VM in a desktop virtualization environment and nodes are not being discovered, the first setting that the consultant should verify is the network adapter configuration, specifically ensuring it is set to a Bridged Adapter. This setting allows the virtual machine hosting the Foundation VM to connect directly to the physical network, making other network nodes visible and reachable during the discovery process. This direct network connection is critical for the Foundation tool to function correctly and discover other nodes.References: Nutanix Bible, Nutanix University
