Question 1
For the enterprise requirement "A legacy application has a few-hour RTO but cannot justify running the complete secondary stack continuously", the team implemented this change: Maintain a pilot-light copy of the essential data and core services and automate remaining capacity restoration. Which observation should be required before the change is approved?
Explanation
Correct Answer
This measures the behavior required by the specific solution, rather than simply checking that it was configured. Pilot light retains critical replicated services while reconstructing additional capacity during recovery. The acceptance condition is linked directly to the scenario: A legacy application has a few-hour RTO but cannot justify running the complete secondary stack continuously.
Incorrect Answers
Read replica lag is measured and promotion produces a usable independent writer during a DR drill. However, this does not establish the required outcome: a drill scales the secondary stack from its minimal footprint within the agreed RTO.
An unauthorized attempt to delete a protected recovery point is denied before retention expires. However, this does not establish the required outcome: a drill scales the secondary stack from its minimal footprint within the agreed RTO.
The released image digest is present in each target Region before workloads attempt recovery. However, this does not establish the required outcome: a drill scales the secondary stack from its minimal footprint within the agreed RTO.
