To find the correct VLAN ID to use during the Foundation of a new 3-node cluster, the consultant should refer to the:

• Deployment Questionnaire: This document typically contains detailed pre-engagement information gathered from the customer, including network specifications such as VLAN IDs. It provides the necessary context and configurations needed for a successful deployment.

• Nutanix University: NCS-Core 6.8 Training (https://university.nutanix.com), which covers the process of gathering and using deployment information.

When nodes are mistakenly configured with incorrect IP addresses and are on a different network, the most effective way to address this is to re-run the Foundation process. By using Foundation, the nodes can be completely re-imaged with the correct network settings and then properly integrated into a new cluster. This ensures that all hardware and software configurations align with the intended network and cluster settings, avoiding potential conflicts and issues that might arise from manual adjustments.

For a multi-tier application where traffic must be limited to specific services and ports across web, application, and database VMs, the optimal approach is to use microsegmentation features provided by Nutanix. Option D, "Categorize the VMs in Prism Central and utilize Flow to set a security policy," is the correct choice.

Nutanix Flow allows for detailed security policies that control VM-to-VM traffic within the same cluster, effectively managing access and communication based on specified criteria like VM category, service, or application type. This solution enables precise control over traffic flows, enhancing security without requiring additional physical or virtual network segmentation.
