Question 920
A company places two redundant application servers in one Availability Zone and calls that zone fault tolerance. Which continuing control BEST supports this AWS approach?
Explanation
Correct Answer
Inventory shared storage and networking dependencies by AZ. This continuing control fits because Multiple machines inside one AZ can still share the same zone failure domain. The associated appropriate response is: Use more than one AZ when the business requires protection from an AZ outage. An observable check is: A simulated AZ outage leaves at least one healthy instance in another AZ.
