The only real-time host for ice-rink wait scoring died during a patch. InstanceCount was pinned at 1 for cost, so availability hit zero. What operational requirement did they skip?
Select an answer to reveal the explanation.
Short Explanation
The only real-time host died during a patch, and InstanceCount was pinned at 1. Fault tolerance means more than one instance or multi-AZ capacity. A tighter Model Monitor schedule does not replace a spare host.
Full Explanation
A single-instance endpoint has no spare capacity, so a patch or host failure drops availability to zero. Fault tolerance here means more than one instance or multi-AZ capacity. That is an operational health requirement, not a Model Monitor drift case, and Rekognition is not that capacity.
