In environments where IPv6 is not allowed for node discovery and the use of an external flat switch by the consultant is also restricted, the viable approach is to connect to the top of rack switch and discover the nodes using IPv4. This method aligns with the customer’s networking policies and leverages the existing network infrastructure to facilitate the discovery and configuration of the nodes within the Nutanix cluster.References: Nutanix Bible, Nutanix University NCS-Core 6.8 resources, and Nutanix official guidelines on node discovery using IPv4.

When facing an error during the installation process that the IPMI IP address is unreachable:

• C. Check the service.log and the individual node log files for more detailed information: Reviewing these log files will provide insights into what might be causing the IPMI connectivity issue, offering specific error messages or network configuration problems that need resolution.

In a typical Nutanix deployment using a flat switch, the Foundation VM, the CVM, and the Hypervisor should all be on the same subnet to facilitate seamless communication and management operations during the initial setup and operation. The IPMI, being a management interface, can be on a different subnet as it serves a different purpose primarily for remote management at the hardware level and does not need to be on the same subnet as the other components for cluster functionality.References:

To ensure that alerts are automatically sent to Nutanix support, the Nutanix feature called Pulse must be enabled. Nutanix Pulse is an automated system intelligence service that collects health information and system alerts from Nutanix clusters and sends them to Nutanix support for proactive monitoring and troubleshooting. Enabling this feature is crucial for maintaining high availability and performance of the Nutanix environment, as it allows Nutanix support to quickly respond to and manage potential issues.References: Nutanix Pulse Documentation, Nutanix Support Services Information.

Based on the subnet assignments from the exhibit provided, the Hypervisor Management IP addresses fall within the 10.170.0.5, 10.170.0.6, 10.170.0.7 range with a subnet mask of 255.255.240.0, indicating a /20 subnet. However, the Foundation VM (FVM) and the Consultant Laptop should ideally be on the same subnet as the Controller Virtual Machine (CVM) to facilitate easy access and management. The CVM IP addresses indicated are 10.170.0.4, 10.170.0.9, and 10.170.0.10 with subnet 255.255.240.0 (/20). Thus, the appropriate choice for the FVM and Laptop that matches the subnet without overlapping with existing IPs and allows network configuration without conflicts would be in the same /24 range as suggested in option D, i.e., FVM: 10.170.25.2/24, Laptop: 10.170.25.12/24.

For a newly deployed Nutanix system where the customer has specified VLAN 10 for management traffic, the consultant should recommend using VLAN 10 for both CVM and AHV host traffic. This VLAN designation ensures that all management, monitoring, and internal cluster communication are on a dedicated network, separate from production VM traffic (VLAN 20) and backup/replication traffic (VLAN 30), thereby enhancing network security and performance.References:
