Microsoft DP-800 Questions & Answers

The joint top-ranked item receives the expected combined score. However, that result would not establish the required outcome: a simple manual calculation matches fusion output.

Both code-number and conceptual test queries find correct passages. However, that result would not establish the required outcome: a simple manual calculation matches fusion output.

A labeled benchmark meets recall for both common and rare queries. However, that result would not establish the required outcome: a simple manual calculation matches fusion output.

Opposite lock acquisition sequences can form a cyclic wait. The actual technical constraint is that lock waits are not resolved merely by allocating faster compute.

Isolation choices define which committed versions are visible across statements. The actual technical constraint is that lock waits are not resolved merely by allocating faster compute.

A poor cardinality estimate can induce unsuitable joins and memory grants. The actual technical constraint is that lock waits are not resolved merely by allocating faster compute.

Review function ownership and data-access boundaries. The current task instead requires this action: specify null, rounding and deterministic behavior explicitly.

Minimize trigger side effects and audit dependent trigger paths. The current task instead requires this action: specify null, rounding and deterministic behavior explicitly.

Implement transactional outbox or supported change notifications. The current task instead requires this action: specify null, rounding and deterministic behavior explicitly.

Generated output is not guaranteed to follow instructions unless independently checked.

Structured JSON preserves field boundaries and escaping for downstream model prompts.

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

Drift detection flags the unexpected column change before publish. However, that result would not establish the required outcome: a test environment with modified index triggers a drift report.

Repository scans show no live credentials while seed records remain deterministic. However, that result would not establish the required outcome: a test environment with modified index triggers a drift report.

A staging upgrade preserves rows and enforces the new constraint. However, that result would not establish the required outcome: a test environment with modified index triggers a drift report.

A cycle can repeatedly regenerate the same nodes in a recursive CTE. The actual technical constraint is that hierarchical traversal requires recursion across parent-child relationships.

Ranking functions identify one top row per group with an explicit order. The actual technical constraint is that hierarchical traversal requires recursion across parent-child relationships.

An outer reference lets the inner aggregate vary by each row's category. The actual technical constraint is that hierarchical traversal requires recursion across parent-child relationships.

Review grants and test bypass paths. The current task instead requires this action: do not use masking as the sole defense for highly sensitive fields.

Tracking principal creation across environments addresses a different database behavior; the relevant distinction is that do not use masking as the sole defense for highly sensitive fields.

Retain logs immutably where required and limit audit administrators. The current task instead requires this action: do not use masking as the sole defense for highly sensitive fields.

Autoscaling the API does not eliminate downstream database exhaustion or unauthorized access.

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

DAB can surface declared stored procedures without granting arbitrary query execution.

A controlled CONTAINS query succeeds after population completes. However, that result would not establish the required outcome: the quoted phrase test excludes documents without that phrase.

Load tests meet target throughput and p95 under realistic data volume. However, that result would not establish the required outcome: the quoted phrase test excludes documents without that phrase.

The exact SKU returns and misleading near codes do not. However, that result would not establish the required outcome: the quoted phrase test excludes documents without that phrase.

A default supplies a value on omission, not a guarantee against explicit bad values. The actual technical constraint is that a surrogate primary key alone does not protect a separate business identifier.

Memory-optimized OLTP can reduce contention but adds feature and durability constraints. The actual technical constraint is that a surrogate primary key alone does not protect a separate business identifier.

External tables abstract remote data but do not automatically remove network or predicate-pushdown costs. The actual technical constraint is that a surrogate primary key alone does not protect a separate business identifier.

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

Keep toolchain versions documented and patched. The current task instead requires this action: audit pipeline changes and approval records.

Automate object inventory comparisons in CI. The current task instead requires this action: audit pipeline changes and approval records.
