You are editing the management network configuration of an ESXi 6.x Host from the vSphere Web Client. You mistakenly put the incorrect VLAN in place for the management network. What action do you…

Manually editing the host via command-line utilities is unnecessary because ESXi handles the rollback automatically without administrator intervention.

When an administrator saves a management network change via the vSphere Web Client, ESXi starts a timer and tests connectivity back to vCenter Server. If the host becomes unreachable - as would happen with an incorrect VLAN ID - ESXi automatically reverts the management network configuration to its previous state before the timer expires. No manual intervention is required.

Restoring factory configuration would erase all host settings and is a drastic, inappropriate action given the built-in rollback feature.

Once the incorrect VLAN disconnects the host, the vSphere Web Client loses communication with it and cannot be used to revert the change - the automatic rollback is what recovers connectivity.
