Which bond mode is set as the default on an AHV Nutanix cluster?

1. Active - Active

2. Active - Backup

3. Load Balancing

4. Passive

The correct answer is: Active - Backup

On an AHV Nutanix cluster, the default bond mode is set to Active - Backup. This configuration is important for ensuring high availability and redundancy. In an Active - Backup bond mode, one network interface (or NIC) is designated as the primary interface, while the other is in a standby mode. The primary NIC carries all the traffic, and if it fails, the secondary NIC takes over seamlessly. This failover approach prevents any interruption in network connectivity, which is crucial for maintaining the performance and reliability of virtualized workloads in a cluster. This mode is especially beneficial in environments where consistent uptime is essential. By using Active - Backup, administrators can ensure that even if a physical network interface experiences issues, the cluster can continue to operate without noticeable disruption. Therefore, this setting is a practical choice for Nutanix clusters, particularly in scenarios where managing risk and maintaining access are priorities. Other bond modes, while useful under specific circumstances, generally require more complex setups and do not provide the same level of simplicity and reliability in failover situations as Active - Backup.
