Question 210

A container workload must authenticate to an Azure database without distributing shared SQL login secrets

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

  1. Test GRANT and denied SELECT events appear with identity, time and action at the audit destination
  2. Old key access can be revoked after authorized clients read all migrated protected records
  3. A restricted principal cannot query or infer prohibited records under the combined controls
  4. A restarted workload connects using its assigned principal and no SQL password is present in deployment secrets

Explanation

Correct Answer

D:

Managed identity supplies short-lived identity-based credentials without a long-lived application password.

Incorrect Answers

A:

Auditing generates event evidence of SQL activity but must be configured for relevant actions and protected storage.

B:

Column-master and column-encryption key lifecycle must be managed carefully to prevent decryption outages.

C:

Masking is a presentation control; filtering, permissions, and inference risks remain if users can query too freely.

Question 211

A RAG index has adjacent snippets repeated many times without measurable recall gains

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

  1. Representative model outputs insert successfully and validation rejects mismatched vector lengths
  2. A representative evaluation meets minimum accuracy at acceptable p95 latency and cost per request
  3. Questions about individual procedures retrieve the correct small passage with its document citation
  4. Benchmark recall meets targets with fewer redundant chunks and lower embedding spend

Explanation

Correct Answer

D:

Excess overlap duplicates tokens and vectors; insufficient overlap may split a needed answer across boundaries.

Incorrect Answers

A:

A fixed-dimensional vector column cannot store embeddings of an incompatible dimension without schema or model changes.

B:

A larger model is not automatically best; task complexity and throughput determine a suitable choice.

C:

Chunk size and overlap trade off retrieval specificity and lost context; arbitrary whole-file chunks are often weak.

Question 212

An application timeouts after a new SQL index is added and a DBA blames networking without measurements

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

  1. Injected deadlocks are retried safely and one logical order is committed exactly once
  2. The blocker chain clears and normal concurrent transactions finish within the expected latency
  3. The identified bottleneck reproduces the timeout and a targeted fix removes it without unrelated changes
  4. Read and update workloads overlap without dirty reads or unacceptable version-store pressure

Explanation

Correct Answer

C:

Latency symptoms may come from blocking, execution plans, throttling or network; one symptom cannot establish root cause.

Incorrect Answers

A:

SQL may abort one deadlock participant; retries can succeed but must not repeat non-idempotent side effects.

B:

Blocking is caused by incompatible locks; addressing the head blocker is different from killing every waiting request.

D:

Versioned read-committed isolation reduces reader/writer blocking but changes consistency semantics and tempdb/version-store demand.

Question 213

A document search should include rows whose JSON array contains the approved attribute value

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

  1. Use SQL graph MATCH patterns over the relevant node and edge tables
  2. Use JSON_CONTAINS or a supported equivalent JSON membership predicate with correct path semantics
  3. Add cycle-aware traversal rules and a tested MAXRECURSION limit where appropriate
  4. Use EDIT_DISTANCE to evaluate edit-operation differences before choosing a threshold

Explanation

Correct Answer

B:

JSON membership testing asks whether a value is contained in the target JSON expression rather than extracting one scalar only.

Incorrect Answers

A:

Graph MATCH expresses edge relationships in a pattern rather than merely comparing flat key columns.

C:

Recursive CTEs need termination and data-integrity safeguards; a recursion cap is a protective limit, not a substitute for valid hierarchy rules.

D:

Edit distance measures changes required to transform a string and must not be confused with semantic meaning.

Question 214

A deployment adds a new reference row required by the application after schema changes

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 authorized workflow gets short-lived credentials and unauthorized repository branches cannot assume the role
  3. An unauthorized PR cannot merge sensitive schema changes without the required owner approval
  4. A failed canary is recovered without losing committed transactions or leaving incompatible schema

Explanation

Correct Answer

A:

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

Incorrect Answers

B:

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

C:

Policy-enforced reviews prevent bypassing designated security and database approvers.

D:

Schema rollback can be unsafe after new writes; recoverability must be designed before a high-risk change.

Question 215

An organization chart must report every subordinate level beneath one manager

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

  1. Use LAG with PARTITION BY entity and an explicit time ORDER BY
  2. Use JSON_OBJECT to build object properties rather than concatenate unescaped strings
  3. Use a recursive CTE with anchor member, recursive member, and safe termination
  4. Use TRY/CATCH with XACT_STATE checks, appropriate rollback, and THROW

Explanation

Correct Answer

C:

Recursive CTEs traverse hierarchies by repeatedly combining results until no new rows are produced.

Incorrect Answers

A:

LAG retrieves a preceding row from a window without a self-join, respecting the defined partition and order.

B:

JSON_OBJECT produces correctly structured JSON property/value pairs and avoids manual quoting errors.

D:

Errors can leave a transaction uncommittable; blindly committing from a catch block is unsafe.

Question 216

A business process needs orchestration when SQL changes and several external SaaS actions are required

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

  1. Enable Azure Monitor Application Insights telemetry with correlation identifiers for the request path
  2. Use an Azure Logic App workflow triggered by a supported database/event connector
  3. Map authenticated claims to DAB roles and enforce least-privilege SQL database access
  4. Declare Data API Builder GraphQL relationships with correct cardinality and column mapping

Explanation

Correct Answer

B:

Logic Apps orchestrate heterogeneous connectors and retries more directly than embedding cross-service calls in a SQL trigger.

Incorrect Answers

A:

Distributed trace correlation helps associate API failures, dependency latency and service operations.

C:

Application identity, API entity permissions and SQL authorization must jointly prevent overbroad access.

D:

GraphQL relationships make defined SQL relations traversable through the API without arbitrary client SQL.

Question 217

A database task performs several slow network operations inside BEGIN TRANSACTION

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

  1. Measure workload saturation and choose an appropriate database service tier or compute configuration
  2. Investigate memory grants and sort/hash spill warnings with plan and runtime evidence
  3. Implement bounded retry with jitter and idempotent business keys for deadlock victims
  4. Move unrelated work outside the transaction and commit the minimal atomic database unit promptly

Explanation

Correct Answer

D:

Long transactions hold locks and version state, worsening throughput and blocking.

Incorrect Answers

A:

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

B:

Improving estimates, ordering or indexing can reduce tempdb spills and prevent large grants from crowding other queries.

C:

SQL may abort one deadlock participant; retries can succeed but must not repeat non-idempotent side effects.

Question 218

An optimizer change makes a critical query use a new plan with much higher IO

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

  1. The regressed query returns identical results with restored acceptable runtime after the approved plan fix
  2. Injected deadlocks are retried safely and one logical order is committed exactly once
  3. Two concurrent allocation tests preserve the required invariant without phantom-induced double allocation
  4. The execution plan switches to an appropriate index seek with a measured logical-read reduction

Explanation

Correct Answer

A:

Query Store retains plan and runtime history so regressions can be tied to specific plan choices.

Incorrect Answers

B:

SQL may abort one deadlock participant; retries can succeed but must not repeat non-idempotent side effects.

C:

Serializable isolation protects range predicates from concurrent changes but may increase blocking and deadlocks.

D:

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

Question 219

A database on Azure storage needs encryption at rest even if an underlying disk is stolen

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

  1. An authorized client decrypts selected columns while the database engine account cannot read the plaintext
  2. Database files are encrypted at rest and restoring from a backup works only with required protector material
  3. A privileged app principal cannot alter or erase protected historical audit records
  4. Old key access can be revoked after authorized clients read all migrated protected records

Explanation

Correct Answer

B:

TDE encrypts database files and backups at rest but does not prevent authorized SQL queries from reading plaintext.

Incorrect Answers

A:

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

C:

Separating audit custody from operational administrators reduces the risk of tampering and premature deletion.

D:

Column-master and column-encryption key lifecycle must be managed carefully to prevent decryption outages.

Question 220

A tax calculation accepts one order amount and returns one decimal rate-adjusted value

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

  1. Create an appropriately typed scalar function and consider inlining and performance constraints
  2. Add SET NOCOUNT ON to a procedure when row-count messages are unnecessary
  3. Use a view or table-valued function when a relation must participate in JOIN operations
  4. Keep the calculation in a side-effect-free SQL function consistent with UDF restrictions

Explanation

Correct Answer

A:

Scalar functions return one value and can encapsulate reusable calculation logic, but implementation choice may affect plan quality.

Incorrect Answers

B:

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

C:

Views and TVFs are relational query sources; stored procedures are invoked with EXEC and do not act as arbitrary table expressions.

D:

T-SQL user-defined functions have side-effect and statement restrictions that differ from stored procedures.
