terminated?
A) The number of instances is balanced across fault domains, the number of instances is
balanced across fault domains, the oldest instance within the fault domain is terminated.
B) The number of instances is balanced across availability domains, the oldest instance
within the fault domain is terminated, the number of instances is balanced across fault
domains.
C) The number of instances is balanced across availability domains, the number of
instances is balanced across fault domains, the oldest instance within the fault
domain is terminated.

When an instance pool scales in, instances are terminated in this order: the number of
instances is balanced across
availability domains, and then balanced across
fault
domains. Finally, within a
fault domain, the oldest instance is terminated first.
