Question 500
At Timberline Foods, the supply-chain systems team is implementing a vendor onboarding project under requirements for continuous approved supplier status. The team says the following incident was fixed: An Azure queue-triggered Function creates duplicate fulfillment tasks when the same message is delivered more than once. Which result BEST proves the intended fix is effective?
Explanation
Correct Answer
Replaying the message generates no second fulfillment task and still reports a successful acknowledgement. This directly tests whether the reported failure has been corrected: An Azure queue-triggered Function creates duplicate fulfillment tasks when the same message is delivered more than once. The intended action was Implement idempotency using a stable event identifier and transactional or alternate-key guard. The observed Timberline Foods outcome is stronger evidence than a completed ticket or a saved configuration alone.
Incorrect Answers
The function authenticates without stored credentials and its identity has only required Dataverse table rights. Such evidence would validate a different change: An Azure Function uses a long-lived Dataverse client secret hard-coded in local and cloud configuration. It follows the separate remedy Use managed identity or a secured identity provider configuration with the corresponding Dataverse application-user permissions. The Timberline Foods scenario instead reports An Azure queue-triggered Function creates duplicate fulfillment tasks when the same message is delivered more than once. The decisive observation must be: Replaying the message generates no second fulfillment task and still reports a successful acknowledgement.
Peak-load tests stay within connection budgets and work completes without an escalating throttling loop. Such evidence would validate a different change: A function opens unlimited simultaneous Dataverse requests under a batch workload and repeatedly hits service-protection limits. It follows the separate remedy Bound concurrency and implement respectful retry/backoff for Dataverse API calls inside the worker. The Timberline Foods scenario instead reports An Azure queue-triggered Function creates duplicate fulfillment tasks when the same message is delivered more than once. The decisive observation must be: Replaying the message generates no second fulfillment task and still reports a successful acknowledgement.
The function retrieves its protected key at runtime and diagnostic output contains no secret material. Such evidence would validate a different change: An Azure Function contains an API signing key in an ordinary environment variable exposed in diagnostics. It follows the separate remedy Use a supported Key Vault secret reference or managed-identity retrieval and prevent secret leakage in logs. The Timberline Foods scenario instead reports An Azure queue-triggered Function creates duplicate fulfillment tasks when the same message is delivered more than once. The decisive observation must be: Replaying the message generates no second fulfillment task and still reports a successful acknowledgement.
