Question 550

An API exposes an administrative stored procedure to every public client. What observable outcome proves the recommendation worked?

  1. The consumer fetches changed row keys since its previous version and then queries current data.
  2. Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.
  3. A test status update starts the intended workflow exactly as designed and records failures.
  4. All environments have expected lookup codes without erasing legitimate transactional rows.

Explanation

Correct Answer

B:

API schema exposure does not supersede stored-procedure privileges or input governance. The observation “Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited” directly confirms the chosen action worked for this situation: An API exposes an administrative stored procedure to every public client.

Incorrect Answers

A:

Change Tracking identifies changed rows and operations, unlike CDC which stores richer change-row history. This observation would not establish that the required result occurred for An API exposes an administrative stored procedure to every public client. The confirming test is: Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.

C:

Logic Apps orchestrate external actions; the SQL change signal and connector privileges must be governed. This observation would not establish that the required result occurred for An API exposes an administrative stored procedure to every public client. The confirming test is: Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.

D:

Reference data needs governed source control and safe migration semantics, not ad hoc admin inserts. This observation would not establish that the required result occurred for An API exposes an administrative stored procedure to every public client. The confirming test is: Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.

Question 551

A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint. Which design choice BEST addresses the root issue?

  1. Configure DAB GraphQL entities and relationships with supported keys and permissions.
  2. Expose procedures only when necessary and enforce per-role execute permissions and parameter validation.
  3. Implement idempotent consumption with stable event or row-version keys and retry-aware checkpoints.
  4. Use supported column-level encryption with governed key access and explicit decryption rights.

Explanation

Correct Answer

B:

API schema exposure does not supersede stored-procedure privileges or input governance. For the described situation—A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint—the targeted fix is Expose procedures only when necessary and enforce per-role execute permissions and parameter validation. A successful test should show: Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.

Incorrect Answers

A:

GraphQL relationships expose linked data through a defined schema, not arbitrary cross-database joins. But that technique does not solve the stated problem—A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint. The needed intervention is Expose procedures only when necessary and enforce per-role execute permissions and parameter validation.

C:

Change triggers and at-least-once deliveries demand explicit deduplication and checkpointing. But that technique does not solve the stated problem—A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint. The needed intervention is Expose procedures only when necessary and enforce per-role execute permissions and parameter validation.

D:

SQL column encryption differs from Always Encrypted in the location of decryption and key trust boundary. But that technique does not solve the stated problem—A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint. The needed intervention is Expose procedures only when necessary and enforce per-role execute permissions and parameter validation.

Question 552

A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint. Which result would provide the strongest acceptance evidence?

  1. Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.
  2. A nested GraphQL query returns expected related data only for authorized users.
  3. A cross-resource query finds the relevant timestamped errors for a simulated incident.
  4. Load tests show reduced latch waits and consistent insert correctness.

Explanation

Correct Answer

A:

API schema exposure does not supersede stored-procedure privileges or input governance. The observation “Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited” directly confirms the chosen action worked for this situation: A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint.

Incorrect Answers

B:

GraphQL relationships expose linked data through a defined schema, not arbitrary cross-database joins. This observation would not establish that the required result occurred for A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint. The confirming test is: Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.

C:

Log Analytics provides centralized queryable telemetry; metrics dashboards alone do not store every event. This observation would not establish that the required result occurred for A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint. The confirming test is: Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.

D:

Page-level hot spots can constrain concurrency beyond disk capacity; fixes require evidence of actual latch waits. This observation would not establish that the required result occurred for A DAB configuration maps a powerful update procedure as an unrestricted entity endpoint. The confirming test is: Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.

Question 553

A service must automatically refresh a derived SQL table whenever a tracked base row changes. What should the database team change FIRST for this workload?

  1. Choose Change Tracking for lightweight row-change identification where changed values are not required.
  2. Externalize secrets and environment values in a managed deployment and validate DAB config at each stage.
  3. Implement idempotent consumption with stable event or row-version keys and retry-aware checkpoints.
  4. Use an approved SqlPackage/DACPAC publishing workflow with preview and permissions.

Explanation

Correct Answer

A:

D:

DACPAC deployment synchronizes model schema under controlled configuration, not arbitrary unreviewed scripts. But that technique does not solve the stated problem—A service must automatically refresh a derived SQL table whenever a tracked base row changes. The needed intervention is Choose Change Tracking for lightweight row-change identification where changed values are not required.

Question 554

A service must automatically refresh a derived SQL table whenever a tracked base row changes. Which acceptance check should accompany the remediation?

  1. The consumer fetches changed row keys since its previous version and then queries current data.
  2. Production starts with the correct database identity and no secrets are embedded in the checked-in config.
  3. A replay of change tables reconstructs expected mutations including relevant old and new values.
  4. The workload connects without a stored SQL secret and denied operations remain blocked.

The confirming test is: The consumer fetches changed row keys since its previous version and then queries current data.

Question 555

An integration team wants to detect incremental changes without parsing all source rows nightly. Which implementation most directly satisfies the stated requirement?

  1. Choose Change Tracking for lightweight row-change identification where changed values are not required.
  2. Apply query depth, pagination and allowed filter policies supported by the API layer.
  3. Use the supported Azure Functions SQL trigger binding with a controlled change source.
  4. Define explicit pipeline dependencies for build, deploy-to-test, test, approval, deploy and verify.

Explanation

Correct Answer
