Microsoft DP-800 Questions & Answers

An unauthorized principal cannot call the model while approved jobs can. However, that result would not establish the required outcome: an authorized test generates an embedding with the expected size.

The tiered approach meets held-out accuracy with lower cost per accepted result. However, that result would not establish the required outcome: an authorized test generates an embedding with the expected size.

All new embeddings insert without dimension errors and search quality is rechecked. However, that result would not establish the required outcome: an authorized test generates an embedding with the expected size.

An INT cannot represent IDs above its signed range. The actual technical constraint is that column-oriented compression and batch processing can accelerate broad aggregations.

Misaligned indexes can block efficient partition maintenance. The actual technical constraint is that column-oriented compression and batch processing can accelerate broad aggregations.

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

Define embedding input contract and refresh triggers per field. The current task instead requires this action: keep source citations and access metadata attached.

Track model quality drift and escalation thresholds. The current task instead requires this action: keep source citations and access metadata attached.

Monitor provider deprecations and certificate changes. The current task instead requires this action: keep source citations and access metadata attached.

Regex substring extraction returns the pattern occurrence, not a tokenized table.

A path existence predicate does not necessarily compute minimal hop count.

JSON_OBJECT constructs a JSON object from typed expressions instead of fragile string concatenation.

The slow query and time window are identified from supported telemetry. However, that result would not establish the required outcome: different representative parameter values meet latency targets after tuning.

The report improves without regression in representative unrelated queries. However, that result would not establish the required outcome: different representative parameter values meet latency targets after tuning.

A stale client receives a conflict and cannot overwrite the newer row. However, that result would not establish the required outcome: different representative parameter values meet latency targets after tuning.

Lexical retrieval protects exact tokens while vectors address paraphrases. The actual technical constraint is that postfusion filtering can leave side-channel exposure and ranking distortion.

RRF operates on list positions and is distinct from raw score interpolation. The actual technical constraint is that postfusion filtering can leave side-channel exposure and ranking distortion.

Approximate structures trade memory, speed and recall depending on data and configuration. The actual technical constraint is that postfusion filtering can leave side-channel exposure and ranking distortion.

Record retry policy and distinguish transient from permanent errors. The current task instead requires this action: use XACT_STATE appropriately before commit or rollback.

Specify ordering when supported and required by consumers. The current task instead requires this action: use XACT_STATE appropriately before commit or rollback.

Specifying missing predecessor behavior explicitly addresses a different database behavior; the relevant distinction is that use XACT_STATE appropriately before commit or rollback.

Changing project source alone does not apply DDL to the deployed database.

Cross-system contracts can fail even when individual SQL procedures are correct.

Moving secrets into a managed secret store or approved OIDC-based identity and rotate exposed credentials would not correct a database project changes a NOT NULL column without backfilling existing NULL rows. Include an appropriate staged data migration and backfill before constraint enforcement.

The pipeline reaches only its intended staging database and resource group. However, that result would not establish the required outcome: scans find no credentials and a staging deployment authenticates securely.

Unapproved branch commits never reach production. However, that result would not establish the required outcome: scans find no credentials and a staging deployment authenticates securely.

A test release with a failing security check is blocked. However, that result would not establish the required outcome: scans find no credentials and a staging deployment authenticates securely.

Levenshtein-style distance measures character edits, not verified real-world identity. The actual technical constraint is that string resemblance cannot guarantee two records represent the same person.

EXISTS is a semijoin-style test of matching rows without duplicating the outer customer. The actual technical constraint is that string resemblance cannot guarantee two records represent the same person.

The graph pattern engine expects node/edge structures, not arbitrary string lists. The actual technical constraint is that string resemblance cannot guarantee two records represent the same person.

Combine DAB permissions with SQL RLS where applicable. The current task instead requires this action: rate-limit expensive query shapes and monitor access logs.

Prevent arbitrary tenant context spoofing and test privileged access. The current task instead requires this action: rate-limit expensive query shapes and monitor access logs.

Reset pooled connections and validate context on each request. The current task instead requires this action: rate-limit expensive query shapes and monitor access logs.
