For enabling node discovery when using the Foundation VM, the network adapter of the Foundation VM must be set to a Bridged Adapter. This configuration allows the VM to appear as a separate device on the same physical network as the host machine, making it possible for the Foundation VM to communicate directly with the nodes that are also connected to the same network. This is essential for node discovery and subsequent imaging operations performed by the Foundation tool.References: Nutanix Foundation Guide, Nutanix Networking Best Practices.

When upgrading ESXi hosts on a Nutanix cluster using One-Click Upgrade, it is crucial to verify that vSphere HA (High Availability) is enabled. This setting ensures that in the event of host failure during the upgrade process, VMs will be automatically restarted on other hosts in the cluster, maintaining availability and minimizing disruption. Verifying this setting is essential to ensure the resilience of the environment during the upgrade.

Noticing a potential typo or error in the DNS server IP address notation:

• D. New IPs provided should be verified to not conflict with the customer's network: It's crucial to verify the accuracy and validity of the IP addresses provided, ensuring there are no typos and that the IPs do not conflict with existing network configurations. The noted IP '192.1685.20' appears to be incorrectly formatted and should be corrected and validated.

If after performing a failover operation the virtual machines have no network access despite the network administrator confirming the correct subnets at both sites, the likely issue is:

• A. Network mappings are not configured for the Remote Site: This configuration oversight means that although the VMs are online, they do not have appropriate network settings that correspond to the network environment at the failover site, resulting in connectivity issues.
