When specifying the availability domains in which to place worker nodes, you now have the option to specify one or more fault domains in each availability domain.

When worker nodes are created, they are distributed as evenly as possible across the availability domains and fault domains you select. If you don't select any fault domains for a particular availability domain, the worker nodes are distributed as evenly as possible across all fault domains in that availability domain.

If you specify a capacity reservation for a node pool, fault domains in the node pool's placement configuration must match the capacity reservation's fault domains.
