Question 900

A contact import wants to normalize repeated punctuation patterns without hand-written nested REPLACE functions

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

  1. Exactly one newest record is selected for each partition entity, including cases with tied timestamps
  2. Input samples with varied spacing normalize correctly and unrelated characters remain unchanged
  3. Documents with the target member match and lookalike values without exact membership do not
  4. Seeded likely duplicates outrank unrelated names without automatically merging different people

Explanation

Correct Answer

B:

Regular-expression replacement handles matching text patterns and should be tested for unintended matches.

Incorrect Answers

A:

Window numbering can select one row per logical partition while a deterministic secondary sort resolves equal timestamps.

C:

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

D:

Jaro-Winkler style similarity rewards matching character patterns and helps with transpositions but cannot prove identity.

Question 901

A knowledge base stores title, body, last-updated timestamp and customer account number

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

  1. Align the SQL VECTOR dimension and model version before inserting embeddings
  2. Use change data capture where supported and manage retention and consumer checkpoints
  3. Choose semantically useful text fields for embeddings and retain identifiers as filter metadata
  4. Use hashes or change versions to re-embed only meaningful changed content

Explanation

Correct Answer

C:

High-entropy IDs and timestamps add noise to natural-language embeddings; structured filters handle them better.

Incorrect Answers

A:

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

B:

CDC captures historical change records from the log, unlike key-only change tracking.

D:

Incremental content tracking saves model calls and avoids rewriting vectors with no semantic change.

Question 902

An international product catalog must preserve multilingual descriptions during inserts and updates

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

  1. Model related entities with graph node and edge tables where graph traversal is required
  2. Configure an IDENTITY column with suitable seed and increment while treating values as identifiers, not gapless sequence numbers
  3. Choose Unicode-compatible character storage such as NVARCHAR for the required text
  4. Use DATETIMEOFFSET or a documented UTC-instant strategy with explicit time zone handling

Explanation

Correct Answer

C:

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

Incorrect Answers

A:

Graph tables represent relationships explicitly and support pattern matching, though ordinary relational joins remain valid for simple cases.

B:

Identity allocation can leave gaps after failures or caching, so it is inappropriate as a legal no-gap counter.

D:

Persisting an offset or normalized instant helps prevent ambiguity that occurs with unqualified local DATETIME values.

Question 903

A team embeds confidential notes and stores them in a shared index without tenant constraints

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

  1. Align the SQL VECTOR dimension and model version before inserting embeddings
  2. Make embedding writes idempotent using source ID and content/version keys
  3. Choose semantically useful text fields for embeddings and retain identifiers as filter metadata
  4. Store tenant and permission metadata with embeddings and enforce it at query time

Explanation

Correct Answer

D:

Vector similarity does not enforce authorization; retrieval still needs tenant/ACL filters.

Incorrect Answers

A:

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

B:

Idempotent update/upsert logic prevents duplicate business vectors during retries and parallel workers.

C:

High-entropy IDs and timestamps add noise to natural-language embeddings; structured filters handle them better.

Question 904

An import accepts national product codes only if they match an established character pattern

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

  1. Good and bad identifier fixtures are classified as expected, including a prefix-only near match
  2. A seeded field containing three eligible occurrences returns a count of three
  3. The response preserves the nested structure and passes JSON parsing in the API client
  4. Exactly one newest record is selected for each partition entity, including cases with tied timestamps

Explanation

Correct Answer

A:

REGEXP_LIKE evaluates a regex match, including anchors that constrain the whole input rather than just a substring.

Incorrect Answers

B:

REGEXP_COUNT returns the number of matches, unlike a boolean REGEXP_LIKE or substring extraction.

C:

JSON_QUERY returns a JSON fragment such as an array/object while JSON_VALUE returns a scalar.

D:

Window numbering can select one row per logical partition while a deterministic secondary sort resolves equal timestamps.

Question 905

A frontend exposes SQL entities through REST and relies on clients to hide confidential columns

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

  1. Evaluate deterministic Always Encrypted for explicitly allowed equality operations and leakage tradeoffs
  2. Enforce authentication, entity permissions and least-privilege database authorization on REST and GraphQL
  3. Classify sensitive fields and align protections with their policy requirements
  4. Enable database auditing with the required event groups, destination and retention

Explanation

Correct Answer

B:

Endpoint convenience does not replace user authentication and data access enforcement in API and SQL layers.

Incorrect Answers

A:

Deterministic encryption enables equality comparisons for matching plaintexts but reveals equality patterns and is less private than randomized encryption.

C:

Information classification guides which columns require stricter access, masking, encryption and auditing.

D:

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

Question 906

An API calls a stored procedure, but application traces stop before the database operation and root cause is unclear

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

  1. The consumer sees changed keys since its checkpoint and handles retention-window expiration correctly
  2. A synthetic request can be followed through API and SQL dependency spans using the same trace context
  3. Replaying the same change does not duplicate business data and checkpoint recovery catches up accurately
  4. The deployed runtime exposes only configured entities and handles expected basic requests

Explanation

Correct Answer

B:

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

Incorrect Answers

A:

Change Tracking reports which rows changed since a version without storing a full sequence of each column change.

C:

At-least-once delivery and retries require idempotent consumers rather than relying on exactly-once invocation.

D:

DAB reads configuration to expose chosen database objects as endpoints, subject to role and permission controls.

Question 907

A team wants to publish a read-only Orders endpoint without accidentally exposing internal financial tables

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

  1. The role can GET permitted orders but cannot query or mutate unexposed tables
  2. A synthetic request can be followed through API and SQL dependency spans using the same trace context
  3. A seeded event completes the approved stages and a transient connector failure follows the defined retry behavior
  4. Replaying the same change does not duplicate business data and checkpoint recovery catches up accurately

Explanation

Correct Answer

A:

DAB entity mapping and permissions limit accessible objects and operations, complementing SQL grants.

Incorrect Answers

B:

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

C:

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

D:

At-least-once delivery and retries require idempotent consumers rather than relying on exactly-once invocation.

Question 908

An analytical fact table has millions of rows and dashboards scan and aggregate a few measures

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

  1. Choose RANGE LEFT or RANGE RIGHT deliberately and test equality at boundary values
  2. Use an appropriate clustered columnstore design for scan-heavy analytics
  3. Implement a system-versioned temporal table with a period and history table
  4. Configure an IDENTITY column with suitable seed and increment while treating values as identifiers, not gapless sequence numbers

Explanation

Correct Answer

B:

Columnstore compression and batch execution are effective on broad aggregations; they are not universally best for singleton OLTP updates.

Incorrect Answers

A:

The selected range direction determines ownership of values equal to boundaries, which affects pruning and rollover.

C:

System-versioned temporal tables maintain historical row versions so FOR SYSTEM_TIME queries can reconstruct earlier states.

D:

Identity allocation can leave gaps after failures or caching, so it is inappropriate as a legal no-gap counter.

Question 909

A security team needs audit evidence retained beyond a compromised workload's lifecycle

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

  1. Sequential tests from two tenants on a reused connection never return the first tenant's data to the second
  2. A restricted principal cannot query or infer prohibited records under the combined controls
  3. A cross-tenant write is rejected and a same-tenant write succeeds for the same application principal
  4. A privileged app principal cannot alter or erase protected historical audit records

Explanation

Correct Answer

D:

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

Incorrect Answers

A:

RLS predicates must receive authenticated tenant context and connection pooling can retain session state unless managed.

B:

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

C:

RLS filter predicates address row visibility while block predicates can stop invalid INSERT/UPDATE operations.

Question 910

A DAB GraphQL consumer needs to constrain query results to authorized fields and predicates

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

  1. Evaluate Change Event Streaming (CES) where the chosen SQL platform supports it
  2. Use change data capture when row-level historical change details are required and supported
  3. Declare Data API Builder GraphQL relationships with correct cardinality and column mapping
  4. Expose controlled filtering parameters and enforce SQL/role boundaries

Explanation

Correct Answer

D:

API filtering reduces unnecessary result transfer but cannot replace server-side authorization.

Incorrect Answers

A:

CES can publish database changes into an event architecture, but supported platform and ordering guarantees must be checked.

B:

CDC records changes from the transaction log for downstream consumption, but latency and retention need management.

C:

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