Question 590

A SQL-derived notifications system generates the same event twice after a function retry. Which result distinguishes a successful implementation from a cosmetic change?

  1. The function processes the expected change and retries safely without duplication.
  2. Production starts with the correct database identity and no secrets are embedded in the checked-in config.
  3. Replaying the same event leaves one effective downstream change without data loss.
  4. Negative tests prove an assistant cannot issue unauthorized DDL or DML through the endpoint.

Explanation

Correct Answer

C:

Change triggers and at-least-once deliveries demand explicit deduplication and checkpointing. The observation “Replaying the same event leaves one effective downstream change without data loss” directly confirms the chosen action worked for this situation: A SQL-derived notifications system generates the same event twice after a function retry.

Incorrect Answers

A:

SQL trigger bindings integrate change detection into function execution but handlers need idempotency. This observation would not establish that the required result occurred for A SQL-derived notifications system generates the same event twice after a function retry. The confirming test is: Replaying the same event leaves one effective downstream change without data loss.

B:

DAB configuration must be deployed with environment-specific secure connections and validated schema mappings. This observation would not establish that the required result occurred for A SQL-derived notifications system generates the same event twice after a function retry. The confirming test is: Replaying the same event leaves one effective downstream change without data loss.

D:

MCP is an action gateway; server-side permissions and tool allowlists are necessary even with trusted prompts. This observation would not establish that the required result occurred for A SQL-derived notifications system generates the same event twice after a function retry. The confirming test is: Replaying the same event leaves one effective downstream change without data loss.

Question 591

A downstream consumer receives repeated change messages and creates duplicate CRM updates. Which solution is the most appropriate for the scenario?

  1. Route appropriate Azure Monitor diagnostic logs into Log Analytics with approved retention.
  2. Implement idempotent consumption with stable event or row-version keys and retry-aware checkpoints.
  3. Choose Change Tracking for lightweight row-change identification where changed values are not required.
  4. Use an SDK-style SQL Database Project with the appropriate build tooling and target platform.

Explanation

Correct Answer

B:

Change triggers and at-least-once deliveries demand explicit deduplication and checkpointing. For the described situation—A downstream consumer receives repeated change messages and creates duplicate CRM updates—the targeted fix is Implement idempotent consumption with stable event or row-version keys and retry-aware checkpoints. A successful test should show: Replaying the same event leaves one effective downstream change without data loss.

Incorrect Answers

A:

Log Analytics provides centralized queryable telemetry; metrics dashboards alone do not store every event. But that technique does not solve the stated problem—A downstream consumer receives repeated change messages and creates duplicate CRM updates. The needed intervention is Implement idempotent consumption with stable event or row-version keys and retry-aware checkpoints.

C:

Change Tracking identifies changed rows and operations, unlike CDC which stores richer change-row history. But that technique does not solve the stated problem—A downstream consumer receives repeated change messages and creates duplicate CRM updates. The needed intervention is Implement idempotent consumption with stable event or row-version keys and retry-aware checkpoints.

D:

SDK-style SQL projects support standardized build workflows and target-platform validation. But that technique does not solve the stated problem—A downstream consumer receives repeated change messages and creates duplicate CRM updates. The needed intervention is Implement idempotent consumption with stable event or row-version keys and retry-aware checkpoints.

Question 592

A downstream consumer receives repeated change messages and creates duplicate CRM updates. What should a technical reviewer verify before approving completion?

  1. The function processes the expected change and retries safely without duplication.
  2. Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.
  3. An authorized restore/rekey drill successfully retrieves needed data under documented policy.
  4. Replaying the same event leaves one effective downstream change without data loss.

Explanation

Correct Answer

D:

Change triggers and at-least-once deliveries demand explicit deduplication and checkpointing.
