Microsoft DP-800 Questions & Answers

Enforce outbound allowlists and unit tests for fields. The current task instead requires this action: compare model output to authoritative SQL totals.

Keep business arithmetic outside uncontrolled model generation. The current task instead requires this action: compare model output to authoritative SQL totals.

Log safe diagnostics and maintain circuit-breaker policy. The current task instead requires this action: compare model output to authoritative SQL totals.

RRF operates on list positions and is distinct from raw score interpolation.

Generate query embeddings with the same approved model and dimension as the column. The relevant technical condition instead is that use RRF to reward documents ranking highly across multiple candidate lists.

Embedding similarity can confuse near-looking product codes that must match exactly.

A privileged SQL-only session cannot read plaintext while an approved client decrypts. However, that result would not establish the required outcome: approved procedures decrypt the target values and unauthorized roles cannot open keys.

A spoofed request cannot change access to another tenant's rows. However, that result would not establish the required outcome: approved procedures decrypt the target values and unauthorized roles cannot open keys.

Anonymous calls fail while authorized SQL workloads succeed. However, that result would not establish the required outcome: approved procedures decrypt the target values and unauthorized roles cannot open keys.

Security enforcement must be tested with the exact executing principal. The actual technical constraint is that session context is only safe as an authorization input when callers cannot impersonate other tenants.

API generation does not automatically imply that exposed data is appropriately authorized. The actual technical constraint is that session context is only safe as an authorization input when callers cannot impersonate other tenants.

Server-side encryption can decrypt inside SQL with authorized key access, unlike client-controlled Always Encrypted. The actual technical constraint is that session context is only safe as an authorization input when callers cannot impersonate other tenants.

Rotate exposed secrets and enable precommit scanning. The current task instead requires this action: avoid overwriting locally maintained fields unexpectedly.

Run deployment reports and a verified rollback strategy. The current task instead requires this action: avoid overwriting locally maintained fields unexpectedly.

Keep isolated test credentials and avoid production data. The current task instead requires this action: avoid overwriting locally maintained fields unexpectedly.

Binary floating-point approximations cannot represent every decimal currency value exactly.

Memory-optimized OLTP can reduce contention but adds feature and durability constraints.

Temporal history captures prior row versions when system versioning is enabled.

Reconciled payment totals match control calculations to the cent. However, that result would not establish the required outcome: the representative query reads fewer pages and retains correct ordered rows.

Sample records validate JSON paths while required keys remain enforced. However, that result would not establish the required outcome: the representative query reads fewer pages and retains correct ordered rows.

A benchmark improves queue throughput while meeting durability requirements. However, that result would not establish the required outcome: the representative query reads fewer pages and retains correct ordered rows.

Embedding similarity can confuse near-looking product codes that must match exactly. The actual technical constraint is that embedding search can retrieve related ideas even without matching literal tokens.

RRF sums reciprocal functions of positions across lists. The actual technical constraint is that embedding search can retrieve related ideas even without matching literal tokens.

Native vector types validate dimensions and avoid repeated parsing of text arrays. The actual technical constraint is that embedding search can retrieve related ideas even without matching literal tokens.

Maintain a controlled model catalog and audit changes. The current task instead requires this action: pin trusted endpoints and monitor certificate or token changes.

Protect branches with required security code review. The current task instead requires this action: pin trusted endpoints and monitor certificate or token changes.

Do not grant production DDL permissions directly to AI tools.

Unbounded result sets waste bandwidth and can overload SQL and API memory.

Publishing the API does not grant the host network or SQL access automatically.

Configuration must resolve the correct database per environment without leaking secrets.

A test payload creates the expected number of items with correct types. However, that result would not establish the required outcome: the execution plan uses the chosen path access strategy and returns matching products.

A test reserves the requested count and avoids collisions. However, that result would not establish the required outcome: the execution plan uses the chosen path access strategy and returns matching products.

A maintenance rehearsal successfully switches a partition with required constraints. However, that result would not establish the required outcome: the execution plan uses the chosen path access strategy and returns matching products.
