Question 980

A model endpoint returns HTTP 429 during load and the SQL integration treats it as a permanent missing answer

Which SQL design or implementation decision most directly addresses this requirement?

  1. Handle retryable REST failures with bounded backoff and an explicit failure state
  2. Evaluate generated answers against a labeled set for groundedness, relevance and correctness
  3. Convert approved SQL result fields into a structured JSON object before model invocation
  4. Enforce SQL tenant authorization before building prompts and citations

Explanation

Correct Answer

A:

Throttling and transient errors require carefully bounded retry; unbounded retries can exhaust database resources.

Incorrect Answers

B:

Fluency is not a reliability metric; RAG performance depends on retrieval, prompt assembly and model behavior.

C:

Structured JSON preserves named fields and reduces ambiguity compared with ad hoc delimited text.

D:

Retrieval-augmented prompts must not bypass database access controls through backend service identity.

Question 981

A rolling release introduces a renamed field but old and new services run simultaneously

Which SQL design or implementation decision most directly addresses this requirement?

  1. Require a defined suite of SQL lint/build/test and review checks on schema pull requests
  2. Use workload identity federation or approved short-lived credentials with least privilege
  3. Configure appropriate SQL project references and validate external dependencies
  4. Use an expand-and-contract compatible schema migration with a staged backfill

Explanation

Correct Answer

D:

Backward-compatible intermediate schema lets mixed app versions operate safely until a later cleanup.

Incorrect Answers

A:

A successful compiler build is necessary but not sufficient for quality or secure schema changes.

B:

Federated OIDC authentication limits reusable secret material while retaining policy-controlled authorization.

C:

Project references inform build-time symbol resolution and make schema dependencies explicit.

Question 982

A single SQL project deploys differently to test and production due to undocumented local connection settings

After the team applies the intended design, which observation would most directly verify that the specific requirement was met?

  1. The cleaned test dataset satisfies the new FK and a failed remediation does not partially apply
  2. The same build artifact deploys to staging and production using explicitly different approved settings
  3. An unreviewed branch cannot deploy to production and approved release candidates can
  4. A clean checkout builds the expected schema artifact without relying on a developer's local database state

Explanation

Correct Answer

B:

A consistent schema artifact should be promoted while environment-specific values are provided securely at deployment.

Incorrect Answers

A:

Data and schema changes must be sequenced so new constraints do not break on preexisting invalid rows.

C:

CI can build frequently while CD must respect protected environments, approvals and test conditions.

D:

SQL Database Projects represent schema as versioned declarative artifacts that can be built and validated.

Question 983

An application is placed on a resource tier unsuited to sustained concurrent analytical scans

Which SQL design or implementation decision most directly addresses this requirement?

  1. Use appropriate dynamic management views to identify waits, blockers and resource pressure
  2. Review actual plans and add a selective useful index aligned with the predicate
  3. Refresh relevant statistics and evaluate automatic statistics maintenance policy
  4. Measure workload saturation and choose an appropriate database service tier or compute configuration

Explanation

Correct Answer

D:

CPU, concurrency and IO constraints drive sizing decisions; indiscriminate upgrades may not solve a poor plan.

Incorrect Answers

A:

DMVs expose current and cumulative SQL diagnostics that help distinguish contention from capacity or query-plan issues.

B:

The optimizer may scan without a suitable search path; index keys should reflect frequently filtered columns.

C:

Statistics provide distribution estimates that influence cardinality and join strategy choices.

Question 984

A database security audit finds conflicting membership and object permissions

After the team applies the intended design, which observation would most directly verify that the specific requirement was met?

  1. An impersonation test confirms confidential SELECT fails and approved access paths still succeed
  2. A permitted identity invokes the model and an unauthorized identity receives an access-denied response
  3. The service can execute its approved procedure but SELECT from the sensitive base table is denied
  4. An unauthorized user cannot read the backup contents and a disaster-recovery drill restores with the proper key

Explanation

Correct Answer

A:

A DENY generally overrides an inherited GRANT for an ordinary user; exceptional cases require explicit security review.

Incorrect Answers

B:

Identity-based model calls reduce secret sprawl and allow endpoint permissions to be scoped and revoked.

C:

Object-level permissions enable task-specific capability without broad exposure to every table.

D:

Backup encryption protects copies outside the live database, but losing the key can make recovery impossible.

Question 985

An Azure SQL vector column receives arrays of different lengths and insert validation is inconsistent

Which SQL design or implementation decision most directly addresses this requirement?

  1. Use a supported VECTOR type with a fixed dimension matching the embedding model
  2. Compare an indexed VECTOR_SEARCH plan against exact distance scans on the target platform
  3. Use exhaustive nearest-neighbor evaluation for accuracy-sensitive or benchmark workloads
  4. Filter by authorization as early as supported in retrieval and never expose unauthorized candidates

Explanation

Correct Answer

A:

SQL vector storage enforces or expects a known dimension and model compatibility for meaningful distance calculations.

Incorrect Answers

B:

ANN index retrieval can reduce full-scan cost if accuracy requirements permit, while brute-force evaluation remains a reference.

C:

Exhaustive nearest-neighbor comparison checks all eligible vectors and provides a recall reference for ANN.

D:

Late filtering after global top-K can leak unauthorized results or starve legitimate tenant matches.

Question 986

An application requires write semantics for a non-updatable view without rewriting clients immediately

After the team applies the intended design, which observation would most directly verify that the specific requirement was met?

  1. The client receives the intended result only and the procedure still records actual affected-row counts internally
  2. A 200-row test produces 200 correct audit details with no duplicate or missing records
  3. A test principal can query approved columns through the view but cannot query the base table directly
  4. A permitted view insert creates exactly the expected normalized base records with correct rollback behavior

Explanation

Correct Answer

D:

INSTEAD OF triggers replace the original DML action and must implement the full intended persistence behavior.

Incorrect Answers

A:

NOCOUNT suppresses DONEINPROC row-count chatter without changing @@ROWCOUNT semantics.

B:

DML triggers run per statement and inserted/deleted can contain multiple rows; singleton assumptions cause data loss.

C:

Views can serve as a restricted interface but must be combined with appropriate permissions and row filtering.

Question 987

Two branches change the same table definition and the merged project has conflicting constraints

After the team applies the intended design, which observation would most directly verify that the specific requirement was met?

  1. Running the deployment twice leaves one expected seed row and the correct feature flags
  2. An unreviewed branch cannot deploy to production and approved release candidates can
  3. The cleaned test dataset satisfies the new FK and a failed remediation does not partially apply
  4. The merged project compiles and integration tests reflect one deliberate schema design

Explanation

Correct Answer

D:

Text merges may not produce semantically compatible database designs, requiring explicit conflict resolution.

Incorrect Answers

A:

Postdeployment scripts handle targeted data initialization but must avoid duplicate or destructive repeated effects.

B:

CI can build frequently while CD must respect protected environments, approvals and test conditions.

C:

Data and schema changes must be sequenced so new constraints do not break on preexisting invalid rows.

Question 988

A finance summary must retain numerical values exactly when an LLM generates narrative prose

Which SQL design or implementation decision most directly addresses this requirement?

  1. Separate model suggestions from human-approved, parameterized database writes
  2. Use retrieval-augmented generation with current authorized SQL-backed context
  3. Enforce SQL tenant authorization before building prompts and citations
  4. Validate model outputs against source numeric fields and use deterministic SQL for calculations

Explanation

Correct Answer

D:

LLMs are not authoritative for arithmetic or source-of-truth values; database computations should remain deterministic.

Incorrect Answers

A:

Model output is untrusted data and must not be treated as authorized executable SQL.

B:

RAG supplies relevant external context at answer time, reducing dependence on stale model memory but not guaranteeing truth.

C:

Retrieval-augmented prompts must not bypass database access controls through backend service identity.

Question 989

A retention process must remove an old time slice without deleting millions of rows individually

Which SQL design or implementation decision most directly addresses this requirement?

  1. Evaluate a memory-optimized table with the correct durability and index choices
  2. Partition the table by an appropriate date key and boundaries with a managed retention plan
  3. Choose Unicode-compatible character storage such as NVARCHAR for the required text
  4. Create a UNIQUE constraint or index on the relevant business key with documented NULL rules

Explanation

Correct Answer

B:

Partition elimination can narrow scans and partition switching can simplify retention when indexes align.

Incorrect Answers

A:

In-Memory OLTP reduces certain latch and lock bottlenecks but has feature and capacity constraints that require workload testing.

C:

Unicode-capable character types retain characters outside a single legacy code page and require appropriate length planning.

D:

Uniqueness for non-primary business attributes is enforced separately from the surrogate primary key.

Question 990

A regulated database stores highly sensitive values that should remain encrypted outside the trusted client boundary

Which SQL design or implementation decision most directly addresses this requirement?

  1. Use Always Encrypted with client-side key handling and protected column encryption metadata
  2. Use synthetic or irreversibly de-identified test data with appropriate access and retention
  3. Implement Row-Level Security with an appropriate predicate function and security policy
  4. Grant narrowly scoped EXECUTE on approved modules and avoid unnecessary base-table permissions

Explanation

Correct Answer

A:

Always Encrypted keeps sensitive column values inaccessible to parties lacking client-side keys, unlike server-only encryption at rest.

Incorrect Answers

B:

Nonproduction environments should not inherit production exposure merely for test convenience.

C:

RLS applies row filters in SQL based on security context, reducing reliance on each client remembering tenant WHERE clauses.

D:

Object-level permissions enable task-specific capability without broad exposure to every table.
