Microsoft DP-800 Questions & Answers

RRF sums reciprocal functions of positions across lists. The actual technical constraint is that RRF operates on list positions and is distinct from raw score interpolation.

Independent retrieval branches can produce overlapping hits and uncalibrated scores. The actual technical constraint is that RRF operates on list positions and is distinct from raw score interpolation.

Smaller distances represent closer vectors for common distance functions. The actual technical constraint is that RRF operates on list positions and is distinct from raw score interpolation.

Retry legitimate deadlock victims with bounded idempotent policy. The current task instead requires this action: alert on sustained blockers and uncommitted transactions.

Avoid universally forcing MAXDOP 1 without workload evaluation. The current task instead requires this action: alert on sustained blockers and uncommitted transactions.

Combine query data with Azure Monitor and service limits. The current task instead requires this action: alert on sustained blockers and uncommitted transactions.

T-SQL UDFs have restrictions on side effects and cannot be arbitrary transactional commands.

Consider converting eligible logic into an inline TVF and compare plans. The relevant technical condition instead is that implement a typed scalar UDF only where its benefits outweigh inline expression overhead.

Using parameterized stored procedures with scoped execution rights would not correct an application needs a reusable deterministic tax rounding expression within a SQL query. Implement a typed scalar UDF only where its benefits outweigh inline expression overhead.

Malformed output is quarantined and valid output produces typed records. However, that result would not establish the required outcome: a test mismatch is detected and the fabricated amount is withheld.

Captured outbound JSON excludes restricted notes and includes needed metrics. However, that result would not establish the required outcome: a test mismatch is detected and the fabricated amount is withheld.

The computed amount matches audited ledger SQL exactly. However, that result would not establish the required outcome: a test mismatch is detected and the fabricated amount is withheld.

Manual changes create drift between intended declarative source and deployed objects. The actual technical constraint is that a valid model build cannot verify current deployed state.

Version control enables traceable schema diffs and rollback planning. The actual technical constraint is that a valid model build cannot verify current deployed state.

Schema compilation alone does not prove business rules are correct. The actual technical constraint is that a valid model build cannot verify current deployed state.

Implement graph integrity checks on writes. The current task instead requires this action: set sensible MAXRECURSION and detect cycles.

Guard against cyclic paths and unsupported graph features. The current task instead requires this action: set sensible MAXRECURSION and detect cycles.

Keep foreign-key columns and nullable policies explicit. The current task instead requires this action: set sensible MAXRECURSION and detect cycles.

Authorized query transformations and inference can expose sensitive values despite masking.

Network allowlisting does not establish user identity or object authorization.

Passwordless CI reduces secret leakage and rotation burden when configured with scoped trust.

Load tests enforce limits and approved users retain service. However, that result would not establish the required outcome: canary tests validate the new route and old clients have an agreed migration path.

The customer fixture returns exactly its own order items. However, that result would not establish the required outcome: canary tests validate the new route and old clients have an agreed migration path.

A nested query returns only permitted order lines for the signed-in user. However, that result would not establish the required outcome: canary tests validate the new route and old clients have an agreed migration path.

Full-text predicates require a configured index and supported column types. The actual technical constraint is that FREETEXT expands linguistic meaning and is not equivalent to exact phrase matching.

Vector search ranks stored embeddings by distance but must honor source permissions. The actual technical constraint is that FREETEXT expands linguistic meaning and is not equivalent to exact phrase matching.

Approximate structures trade memory, speed and recall depending on data and configuration. The actual technical constraint is that FREETEXT expands linguistic meaning and is not equivalent to exact phrase matching.

Separate creation time from event time and validate clock policy.

Pre-create boundaries and monitor data skew. The current task instead requires this action: track business-key changes and uniqueness collation policy.

Use transactional change control and rehearse rollback. The current task instead requires this action: track business-key changes and uniqueness collation policy.

Configuring CODEOWNERS and required reviews for the finance database paths would not correct a pipeline deploys to production immediately after any branch push. Use protected branch triggers, environment approval gates and deployment-specific identities.

Branch policies are governance controls that prevent unreviewed deployment inputs.

Schema reconciliation can propose destructive changes that threaten existing records.
