Microsoft DP-800 Questions & Answers

Avoid counting duplicates in one list twice. The current task instead requires this action: keep rank offset and truncation policies documented.

Choose exact versus linguistic search deliberately. The current task instead requires this action: keep rank offset and truncation policies documented.

Verify platform, dimension limit and client compatibility. The current task instead requires this action: keep rank offset and truncation policies documented.

Standardize resource update order and review deadlock graph evidence. The relevant technical condition instead is that identify the blocking head using supported DMV and wait analysis before scaling.

Database-level settings can affect many workloads and engine versions differently.

Using appropriate locking or optimistic concurrency validation to make stock decrement atomic would not correct an API times out due to blocked UPDATE requests, but a team proposes adding more CPU. Identify the blocking head using supported DMV and wait analysis before scaling.

A read-only function compiles while the separate write path has explicit authorization. However, that result would not establish the required outcome: boundary amounts return correct DECIMAL values in unit tests.

A migration test catches incompatible column modification before production. However, that result would not establish the required outcome: boundary amounts return correct DECIMAL values in unit tests.

A test UPDATE completes once with expected values and no recursion error. However, that result would not establish the required outcome: boundary amounts return correct DECIMAL values in unit tests.

Generated output is not guaranteed to follow instructions unless independently checked. The actual technical constraint is that language model fluency does not establish numerical correctness.

JSON encoding preserves numeric representation better than locale-dependent concatenation. The actual technical constraint is that language model fluency does not establish numerical correctness.

Arbitrary external REST calls risk server-side request forgery and data exfiltration. The actual technical constraint is that language model fluency does not establish numerical correctness.

Reconcile sanctioned hotfixes into source control promptly. The current task instead requires this action: define drift policy for emergency fixes.

Use deployment reports and rollback planning for destructive changes. The current task instead requires this action: define drift policy for emergency fixes.

Restrict secret access by environment and role. The current task instead requires this action: define drift policy for emergency fixes.

A cycle can repeatedly regenerate the same nodes in a recursive CTE.

Graph relationships support path queries but still need guarded edge permissions.

Regex replacement can transform all matching substrings without fixed positions.

A simulated low-privilege role cannot infer restricted personal identifiers. However, that result would not establish the required outcome: low-privilege results show masked account numbers while privileged tests show permitted values.

An anonymous request is denied and an approved role sees only permitted fields. However, that result would not establish the required outcome: low-privilege results show masked account numbers while privileged tests show permitted values.

Supported equality or enclave test cases behave as designed without broad plaintext exposure. However, that result would not establish the required outcome: low-privilege results show masked account numbers while privileged tests show permitted values.

Autoscaling the API does not eliminate downstream database exhaustion or unauthorized access. The actual technical constraint is that API endpoint changes can break consumers even if the underlying database remains healthy.

Response caching trades freshness for latency and may serve obsolete facts. The actual technical constraint is that API endpoint changes can break consumers even if the underlying database remains healthy.

DAB entity projection and permissions determine the API data surface. The actual technical constraint is that API endpoint changes can break consumers even if the underlying database remains healthy.

Inspect index freshness and population failures. The current task instead requires this action: choose exact versus linguistic search deliberately.

Maintain an exact KNN baseline for regression testing. The current task instead requires this action: choose exact versus linguistic search deliberately.

Record contribution of each retrieval branch for diagnostics. The current task instead requires this action: choose exact versus linguistic search deliberately.

A default supplies a value on omission, not a guarantee against explicit bad values.

Missing future boundaries force incoming values into the existing terminal partition.

Using compatible staging tables and ALTER TABLE SWITCH after checking alignment and constraints would not correct an order system accepts duplicate order numbers and downstream reconciliation double-counts orders. Enforce an appropriate UNIQUE constraint on the business order key after cleaning duplicates.

A billing SQL PR requires a finance-code-owner approval before merge. However, that result would not establish the required outcome: unapproved branch commits never reach production.

The project builds on a clean agent and generates the expected DACPAC. However, that result would not establish the required outcome: unapproved branch commits never reach production.

A test environment with modified index triggers a drift report. However, that result would not establish the required outcome: unapproved branch commits never reach production.
