Question 540

A team wants to expose selected SQL tables through a managed API configuration with minimal custom code. What measurement or test best demonstrates that the requirement is satisfied?

  1. Production starts with the correct database identity and no secrets are embedded in the checked-in config.
  2. An authorized REST request returns only configured fields and unsupported table access is rejected.
  3. A replay of change tables reconstructs expected mutations including relevant old and new values.
  4. Inference attempts no longer expose sensitive results to unauthorized principals.

Explanation

Correct Answer

B:

Data API builder maps SQL objects to HTTP endpoints according to its explicit configuration and policy. The observation “An authorized REST request returns only configured fields and unsupported table access is rejected” directly confirms the chosen action worked for this situation: A team wants to expose selected SQL tables through a managed API configuration with minimal custom code.

Incorrect Answers

A:

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 team wants to expose selected SQL tables through a managed API configuration with minimal custom code. The confirming test is: An authorized REST request returns only configured fields and unsupported table access is rejected.

C:

CDC records change data for replay, unlike simple change tracking versions. This observation would not establish that the required result occurred for A team wants to expose selected SQL tables through a managed API configuration with minimal custom code. The confirming test is: An authorized REST request returns only configured fields and unsupported table access is rejected.

D:

DDM is a display feature, not a complete security boundary against statistical inference. This observation would not establish that the required result occurred for A team wants to expose selected SQL tables through a managed API configuration with minimal custom code. The confirming test is: An authorized REST request returns only configured fields and unsupported table access is rejected.

Question 541

A frontend wants GraphQL queries over related customer and order entities. What is the most defensible next technical action?

  1. Use Azure Logic Apps with an approved SQL/change connector and scoped authentication.
  2. Expose procedures only when necessary and enforce per-role execute permissions and parameter validation.
  3. Configure DAB GraphQL entities and relationships with supported keys and permissions.
  4. Make seed scripts idempotent using validated keys and conditional updates/inserts.

Explanation

Correct Answer

C:

GraphQL relationships expose linked data through a defined schema, not arbitrary cross-database joins. For the described situation—A frontend wants GraphQL queries over related customer and order entities—the targeted fix is Configure DAB GraphQL entities and relationships with supported keys and permissions. A successful test should show: A nested GraphQL query returns expected related data only for authorized users.

Incorrect Answers

A:

Logic Apps orchestrate external actions; the SQL change signal and connector privileges must be governed. But that technique does not solve the stated problem—A frontend wants GraphQL queries over related customer and order entities. The needed intervention is Configure DAB GraphQL entities and relationships with supported keys and permissions.

B:

API schema exposure does not supersede stored-procedure privileges or input governance. But that technique does not solve the stated problem—A frontend wants GraphQL queries over related customer and order entities. The needed intervention is Configure DAB GraphQL entities and relationships with supported keys and permissions.

D:

Idempotency makes repeated migration runs safe under retries and partial failures. But that technique does not solve the stated problem—A frontend wants GraphQL queries over related customer and order entities. The needed intervention is Configure DAB GraphQL entities and relationships with supported keys and permissions.

Question 542

A frontend wants GraphQL queries over related customer and order entities. Which result distinguishes a successful implementation from a cosmetic change?

  1. Replaying the same event leaves one effective downstream change without data loss.
  2. A sample slow API request can be traced to its database call and error details.
  3. A nested GraphQL query returns expected related data only for authorized users.
  4. Repeated deployment yields the same final reference rows without duplicates.

Explanation

Correct Answer

C:

GraphQL relationships expose linked data through a defined schema, not arbitrary cross-database joins. The observation “A nested GraphQL query returns expected related data only for authorized users” directly confirms the chosen action worked for this situation: A frontend wants GraphQL queries over related customer and order entities.

Incorrect Answers

A:

This observation would not establish that the required result occurred for A frontend wants GraphQL queries over related customer and order entities. The confirming test is: A nested GraphQL query returns expected related data only for authorized users.

B:

Application Insights complements database-level metrics by connecting application requests to dependencies. This observation would not establish that the required result occurred for A frontend wants GraphQL queries over related customer and order entities. The confirming test is: A nested GraphQL query returns expected related data only for authorized users.

D:

Idempotency makes repeated migration runs safe under retries and partial failures. This observation would not establish that the required result occurred for A frontend wants GraphQL queries over related customer and order entities. The confirming test is: A nested GraphQL query returns expected related data only for authorized users.

Question 543

A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests. Which solution is the most appropriate for the scenario?

  1. Use the supported Azure Functions SQL trigger binding with a controlled change source.
  2. Externalize secrets and environment values in a managed deployment and validate DAB config at each stage.
  3. Use managed key custody and separation of duties appropriate to the chosen encryption scheme.
  4. Configure DAB GraphQL entities and relationships with supported keys and permissions.

Explanation

Correct Answer

D:

GraphQL relationships expose linked data through a defined schema, not arbitrary cross-database joins. For the described situation—A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests—the targeted fix is Configure DAB GraphQL entities and relationships with supported keys and permissions. A successful test should show: A nested GraphQL query returns expected related data only for authorized users.

Incorrect Answers

A:

SQL trigger bindings integrate change detection into function execution but handlers need idempotency. But that technique does not solve the stated problem—A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests. The needed intervention is Configure DAB GraphQL entities and relationships with supported keys and permissions.

B:

DAB configuration must be deployed with environment-specific secure connections and validated schema mappings. But that technique does not solve the stated problem—A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests. The needed intervention is Configure DAB GraphQL entities and relationships with supported keys and permissions.

C:

Key hierarchy and role separation prevent one compromised principal from controlling ciphertext and keys. But that technique does not solve the stated problem—A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests. The needed intervention is Configure DAB GraphQL entities and relationships with supported keys and permissions.

Question 544

A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests. What should a technical reviewer verify before approving completion?

  1. Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.
  2. The consumer fetches changed row keys since its previous version and then queries current data.
  3. Test queries as the support role show masked values while authorized privileged queries remain correct.
  4. A nested GraphQL query returns expected related data only for authorized users.

Explanation

Correct Answer

D:

GraphQL relationships expose linked data through a defined schema, not arbitrary cross-database joins. The observation “A nested GraphQL query returns expected related data only for authorized users” directly confirms the chosen action worked for this situation: A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests.

Incorrect Answers

A:

API schema exposure does not supersede stored-procedure privileges or input governance. This observation would not establish that the required result occurred for A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests. The confirming test is: A nested GraphQL query returns expected related data only for authorized users.

B:

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 A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests. The confirming test is: A nested GraphQL query returns expected related data only for authorized users.

C:

Dynamic Data Masking changes query presentation but does not replace encryption or prevent all inferential access. This observation would not establish that the required result occurred for A development team needs a relationship-aware query API that avoids issuing many unrelated HTTP requests. The confirming test is: A nested GraphQL query returns expected related data only for authorized users.

Question 545

A REST API returns every customer record even when a request asks for one page. What should the SQL developer implement after verifying the conditions?

  1. Configure the supported pagination and filtering mechanisms with stable ordering.
  2. Expose procedures only when necessary and enforce per-role execute permissions and parameter validation.
  3. Use the supported Azure Functions SQL trigger binding with a controlled change source.
  4. Identify the cycle and standardize access order, shorten transactions, and add bounded retry on deadlock victims.

Explanation

Correct Answer

A:

API pagination and predicates reduce overfetching; unsupported query fields must be controlled. For the described situation—A REST API returns every customer record even when a request asks for one page—the targeted fix is Configure the supported pagination and filtering mechanisms with stable ordering. A successful test should show: Paged calls return bounded, correctly filtered sets with consistent continuation behavior.

Incorrect Answers

B:

API schema exposure does not supersede stored-procedure privileges or input governance. But that technique does not solve the stated problem—A REST API returns every customer record even when a request asks for one page. The needed intervention is Configure the supported pagination and filtering mechanisms with stable ordering.

C:

D:

Deadlocks form cycles of lock dependencies; a victim rollback must be handled and root lock patterns improved. But that technique does not solve the stated problem—A REST API returns every customer record even when a request asks for one page. The needed intervention is Configure the supported pagination and filtering mechanisms with stable ordering.

Question 546

A REST API returns every customer record even when a request asks for one page. Which verification finding is most specific to this scenario?

  1. Oversized queries are denied or paged while ordinary client requests meet latency goals.
  2. Unauthorized callers cannot invoke sensitive procedures and allowed calls are audited.
  3. Paged calls return bounded, correctly filtered sets with consistent continuation behavior.
  4. The same schema artifact can target test and production with independently managed configuration.

Explanation

Correct Answer

C:

API pagination and predicates reduce overfetching; unsupported query fields must be controlled. The observation “Paged calls return bounded, correctly filtered sets with consistent continuation behavior” directly confirms the chosen action worked for this situation: A REST API returns every customer record even when a request asks for one page.

Incorrect Answers

A:

GraphQL and REST query surfaces require limits to prevent accidental overfetch and resource exhaustion. This observation would not establish that the required result occurred for A REST API returns every customer record even when a request asks for one page. The confirming test is: Paged calls return bounded, correctly filtered sets with consistent continuation behavior.

B:

API schema exposure does not supersede stored-procedure privileges or input governance. This observation would not establish that the required result occurred for A REST API returns every customer record even when a request asks for one page. The confirming test is: Paged calls return bounded, correctly filtered sets with consistent continuation behavior.

D:

Separating environment configuration from schema source avoids drift and secret exposure. This observation would not establish that the required result occurred for A REST API returns every customer record even when a request asks for one page. The confirming test is: Paged calls return bounded, correctly filtered sets with consistent continuation behavior.

Question 547

A client needs scalable pagination over millions of SQL objects through Data API builder. Which approach achieves the intended result without bypassing the stated controls?
