Microsoft DP-800 Questions & Answers

Plan at-least-once behavior and guard duplicate processing. The current task instead requires this action: handle replay, deletion and watermark recovery.

Define embedding input contract and refresh triggers per field. The current task instead requires this action: handle replay, deletion and watermark recovery.

Track model quality drift and escalation thresholds. The current task instead requires this action: handle replay, deletion and watermark recovery.

More synchronous retries lengthen the transaction and increase coupling to an external model; the right remedy is to decouple change capture from inference work.

Embeddings are computed numeric representations and are not created merely by defining a VECTOR column.

Embedding inputs can expose or encode sensitive data without adding retrieval value.

The project builds on a clean agent and generates the expected DACPAC. However, that result would not establish the required outcome: the project build and staging publish identify unsupported constructs before production.

Drift detection flags the unexpected column change before publish. However, that result would not establish the required outcome: the project build and staging publish identify unsupported constructs before production.

Repository scans show no live credentials while seed records remain deterministic. However, that result would not establish the required outcome: the project build and staging publish identify unsupported constructs before production.

JSON_OBJECT constructs a JSON object from typed expressions instead of fragile string concatenation. The actual technical constraint is that JSON_VALUE extracts a scalar path, while OPENJSON can shred collections.

Regex replacement can transform all matching substrings without fixed positions. The actual technical constraint is that JSON_VALUE extracts a scalar path, while OPENJSON can shred collections.

Silently suppressed exceptions create false evidence of committed work. The actual technical constraint is that JSON_VALUE extracts a scalar path, while OPENJSON can shred collections.

Keep identifier search separate from semantic descriptions. The current task instead requires this action: tune fusion and metadata filters from labeled evaluations.

Keep rank offset and truncation policies documented. The current task instead requires this action: tune fusion and metadata filters from labeled evaluations.

Rebenchmark after model or data growth. The current task instead requires this action: tune fusion and metadata filters from labeled evaluations.

Reviewing dependency effects and change the schema-bound view deliberately before modifying underlying objects would not correct a team tries to insert through a view containing aggregation and GROUP BY. Use a supported write path or redesign the view rather than assuming all views are updatable.

A scalar function returns a single value, whereas a TVF returns columns and rows.

A DELETE trigger exposes removed rows via deleted, not inserted.

Representative joins show improved estimates and correct results. However, that result would not establish the required outcome: a filtered test returns only transactions for the specified customer.

A read-only function compiles while the separate write path has explicit authorization. However, that result would not establish the required outcome: a filtered test returns only transactions for the specified customer.

Tests resolve the intended procedure and handle null/invalid inputs. However, that result would not establish the required outcome: a filtered test returns only transactions for the specified customer.

Silently suppressed exceptions create false evidence of committed work. The actual technical constraint is that transient retries can replay committed work even after client-side timeouts.

JSON_ARRAYAGG can collect multiple row values into a JSON array. The actual technical constraint is that transient retries can replay committed work even after client-side timeouts.

JSON_VALUE extracts a scalar path, while OPENJSON can shred collections. The actual technical constraint is that transient retries can replay committed work even after client-side timeouts.

Index frequently filtered paths only after measured need. The current task instead requires this action: reject malformed payloads and account for missing paths.

Document whether reusable results require temp tables or views. The current task instead requires this action: reject malformed payloads and account for missing paths.

Use supplemental identifiers and human approval for merges. The current task instead requires this action: reject malformed payloads and account for missing paths.

An authorization error occurs before model inference can produce valid content.

RAG is appropriate only if the retriever enforces contractual permissions.

Sending unauthorized rows to a model is a disclosure even if its final answer omits them.

Rows matching the expected category are returned in a controlled test. However, that result would not establish the required outcome: a JSON parser reads the intended named fields and escaped text.

A test discovers the expected connected device chain. However, that result would not establish the required outcome: a JSON parser reads the intended named fields and escaped text.

A sample network returns the known minimal path when explicitly requested. However, that result would not establish the required outcome: a JSON parser reads the intended named fields and escaped text.
