Question 470
A Logic Apps security playbook retries after a network timeout and issues duplicate device-isolation requests against the same endpoint. Which transaction-handling design prevents unsafe replays?
Explanation
Correct Answer
Use incident/device action IDs, idempotency checks and authoritative Defender device state/result lookups before retrying; record outcome and suppress duplicate operations.
Incorrect Answers
Adding playbook role permissions does not prevent retries from replaying actions that already succeeded.
Changing incident closure criteria is unrelated to network retry behavior of an isolation action.
Human approval can govern risky responses but does not itself detect an already completed isolation when a retry occurs.
