For scenarios requiring VM availability during unplanned outages, AHV Metro with Witness Operation is designed to handle such situations. AHV Metro Availability enables synchronous replication between two sites with a witness that arbitrates site availability in case of a split-brain scenario. This setup is intended for automatic failover during service disruptions, ensuring continuous availability of VMs without manual intervention.

Before going on-site to deploy a Nutanix cluster, the following prerequisites are crucial:
* A. Complete the kickoff call and validate the BOM (Bill of Materials): This ensures that all necessary components are accounted for and any discrepancies or missing items are addressed prior to installation.
* C. Validate whether the cluster questionnaire is complete and if the physical switch configurations are complete: Ensuring that all relevant customer and network information is obtained and validated is critical to avoid delays or issues during the physical installation and configuration of the cluster.

Given that the customer is using a Cisco Nexus 9k switch and wants to deploy ESXi with a vSphere Distributed Switch while using LACP, the consultant should ensure that the customer configures:
* D. no lacp suspend-individual: This command ensures that LACP doesn't suspend the individual port if it does not receive LACP PDUs from the other side, which is crucial in environments where continuous connectivity is required for all member links of the port-channel to maintain uninterrupted network services.

The requirements specify the use of LACP with multiple VLANs and without the use of a native VLAN.
Trunk ports must be configured to carry multiple VLANs, which is necessary for scenarios involving LACP across multiple switches (MLAG or vPC). Setting the native VLAN to default and not using it in traffic management while trunking the ports meets these needs effectively.
