Microsoft DP-800 Questions & Answers

A migration test catches incompatible column modification before production. However, that result would not establish the required outcome: both tools return the same verified sales metric from the view.

Tests resolve the intended procedure and handle null/invalid inputs. However, that result would not establish the required outcome: both tools return the same verified sales metric from the view.

A measured rewrite returns identical values with lower CPU. However, that result would not establish the required outcome: both tools return the same verified sales metric from the view.

GraphQL relationship traversal can increase data exposure if access is too broad. The actual technical constraint is that agents can turn natural-language requests into real database mutations if tools permit.

Embedding static credentials in SQL code can expose model access and billing. The actual technical constraint is that agents can turn natural-language requests into real database mutations if tools permit.

Identity permission at one Azure service does not imply access to adjacent resources. The actual technical constraint is that agents can turn natural-language requests into real database mutations if tools permit.

Scope identity permissions and review token failures. The current task instead requires this action: track principal creation across environments.

Review view definitions and permission chains. The current task instead requires this action: track principal creation across environments.

Expire elevation and log the migration transaction. The current task instead requires this action: track principal creation across environments.

Text-only models cannot directly interpret image content without a supporting vision pipeline.

Embedding the wrong language source can degrade multilingual retrieval quality.

Using heading-aware and language-aware chunk boundaries with source metadata would not correct a customer-support assistant must classify multilingual complaints with a small latency budget. Evaluate multilingual compact and large models on representative language and latency benchmarks.

Checkout commits within SLO while notifications eventually deliver. However, that result would not establish the required outcome: a 50-row INSERT updates all required summary totals correctly.

The function composes correctly in a FROM clause. However, that result would not establish the required outcome: a 50-row INSERT updates all required summary totals correctly.

Injected failure rolls back all intended writes and preserves integrity. However, that result would not establish the required outcome: a 50-row INSERT updates all required summary totals correctly.

Unconstrained prose is fragile to parse and can omit required keys. The actual technical constraint is that model size increases cost and latency without guaranteeing proportional quality gains.

Modeling invocation can export inputs and incur charges, so object privileges matter would not correct an app selects an enormous model for every short product tag and then exceeds budget. Model size increases cost and latency without guaranteeing proportional quality gains.

External endpoint configuration can become stale independently of database code. The actual technical constraint is that model size increases cost and latency without guaranteeing proportional quality gains.

Audit pipeline changes and approval records. The current task instead requires this action: keep ownership mapping updated when teams change.

Require branch protection and code review for production. The current task instead requires this action: keep ownership mapping updated when teams change.

Requiring reviews for schema changes addresses a different database behavior; the relevant distinction is that keep ownership mapping updated when teams change.

AI chat providers and extensions may retain shared content outside the database boundary.

An MCP client needs a discoverable trusted server and permissions to run tools.

Personal and enterprise assistants can have different retention and policy controls.

The approved identity receives a 2xx response while an unauthorized one fails. However, that result would not establish the required outcome: a staging request returns the expected status and schema-valid response.

A throttled test eventually succeeds or leaves a recoverable queue record. However, that result would not establish the required outcome: a staging request returns the expected status and schema-valid response.

A cross-client negative test yields no unauthorized quoted text. However, that result would not establish the required outcome: a staging request returns the expected status and schema-valid response.

Parsing nested arrays into typed rows reduces fragile manual string extraction. The actual technical constraint is that malformed payloads can break downstream JSON_VALUE and OPENJSON processing.

Column-oriented compression and batch processing can accelerate broad aggregations. The actual technical constraint is that malformed payloads can break downstream JSON_VALUE and OPENJSON processing.

A surrogate primary key alone does not protect a separate business identifier. The actual technical constraint is that malformed payloads can break downstream JSON_VALUE and OPENJSON processing.

Monitor connection failures and restrict ingress. The current task instead requires this action: use telemetry and abuse alerting across API and SQL.

Block accidental production connection strings in repository review. The current task instead requires this action: use telemetry and abuse alerting across API and SQL.

Use consistent ordering and monitor costly filters. The current task instead requires this action: use telemetry and abuse alerting across API and SQL.
