Question

Utilities operate a SCADA gateway stack in AWS with written AZ-loss runbooks that have not been exercised recently. What should architects schedule?

Accepted Answer

Run controlled game-day failure-injection exercises that simulate AZ loss and validate that recovery runbooks and automation still work. — Untested runbooks are campfire stories—schedule a game day, pull an AZ (safely), and see if the SCADA gateway recovery still works. Waiting for a real outage is not a drill.

Answer

Assume runbooks remain correct forever without testing because documentation cannot go stale.

Answer

Delete the runbooks to reduce operational clutter before the next audit.

Answer

Only test failover during a real regional emergency with citizens already impacted.
