According to Nutanix best practices for ESXi clusters, using a vSphere Standard Switch with "Route based on originating port ID" is recommended for load balancing. This method ensures that the same virtual port ID within a vSwitch uses the same uplink from the vSwitch. This load balancing policy provides an even distribution of traffic and redundancy by utilizing both NICs effectively without requiring any specific physical switch configurations, such as EtherChannel or LACP.References: The Nutanix Bible, NCS-Core 6.8 course content, and VMware’s documentation on vSphere Standard Switch load balancing methods.

When deploying Nutanix hardware, it is essential to ensure that all necessary components are included in the Bill of Materials (BOM). In this case, the BOM includes SFP+ modules but lacks the fiber cables needed for connectivity. The SFP+ modules indicate a requirement for fiber optic cables, and it's crucial for the consultant to ensure the client understands their responsibility to procure compatible cables. Nutanix typically does not provide fiber cables as these are considered network infrastructure components, which vary based on specific network requirements and setups.References:

The most straightforward approach for increasing security by disabling password authentication and moving to key-based SSH on a Nutanix cluster involves:

• C. Enable Cluster Lockdown and provide an RSA key: Cluster Lockdown mode restricts management access to the cluster, ensuring that only key-based SSH authentication is used to access the CVM and AHV hosts, enhancing security by eliminating the use of passwords.

If the Foundation VM fails to boot and other methods need to be considered, the best alternative is the Foundation Applet. This lightweight tool runs on a laptop or other device and doesn't require booting a VM, providing a straightforward method to image Nutanix hardware, particularly useful in situations where hardware constraints or other issues prevent the use of a full Foundation VM.
