A finance team needs pre-aggregated monthly measures for repeatedly queried large order tables. The team plans to implement this change: Group by the desired grain and calculate SUM or COUNT aggregations. Which result best verifies the intended outcome?
Aggregations reduce detail at a documented grain and support efficient summaries. This evidence exercises the actual success condition rather than only confirming that a resource exists.

That observation would verify a different goal: A selected day's summary equals the aggregate of underlying raw rows. It does not demonstrate the specific required result: Summed monthly totals reconcile to the detailed source fact rows.
That observation would verify a different goal: The new date field matches source timestamps for boundary cases and the intended timezone. It does not demonstrate the specific required result: Summed monthly totals reconcile to the detailed source fact rows.

An organization stores nested event arrays but its reporting grain should be one record per event attribute. The team plans to implement this change: Flatten or explode the nested collection while documenting how the output grain changes. Which result best verifies the intended outcome?
Exploding arrays changes cardinality and must be reconciled against source nested item counts. This evidence exercises the actual success condition rather than only confirming that a resource exists.

DirectQuery sends queries to the source at report time, trading freshness for source load and response time. The proposed action directly targets the problem described in the scenario.
Use the lakehouse SQL analytics endpoint where its capabilities satisfy the read query. is an approach for a different requirement: The SQL analytics endpoint exposes compatible lakehouse tables for SQL-based exploration. In the present case, directQuery sends queries to the source at report time, trading freshness for source load and response time.
Choose a Fabric warehouse as the SQL-oriented analytical store. is an approach for a different requirement: A warehouse provides relational SQL capabilities and structured analytical tables in Fabric. In the present case, directQuery sends queries to the source at report time, trading freshness for source load and response time.
Share the governed warehouse or OneLake-backed tables through appropriate authorized access. is an approach for a different requirement: Reusing a single authoritative store avoids conflicting data definitions caused by uncontrolled replication. In the present case, directQuery sends queries to the source at report time, trading freshness for source load and response time.
A customer table must display the latest address for each person while retaining raw source history elsewhere. Which implementation decision best addresses the stated requirement?
Deterministic deduplication requires a business key and priority or timestamp, not arbitrary row selection. The proposed action directly targets the problem described in the scenario.
Clean and convert amounts to an appropriate numeric type before aggregation. is an approach for a different requirement: Arithmetic requires typed numeric values rather than locale-formatted text. In the present case, deterministic deduplication requires a business key and priority or timestamp, not arbitrary row selection.
Build an appropriate daily aggregation table or view with a defined grain. is an approach for a different requirement: Precomputed summaries can reduce repeated large scans while raw data remains for investigation. In the present case, deterministic deduplication requires a business key and priority or timestamp, not arbitrary row selection.
Create a transformation expression that concatenates name components with null handling. is an approach for a different requirement: Enrichment should handle optional source fields explicitly to avoid unexpected null results. In the present case, deterministic deduplication requires a business key and priority or timestamp, not arbitrary row selection.
The existing KQL query averages all severities and overstates the target workload. Which implementation decision best addresses the stated requirement?
The where operator filters event rows, allowing subsequent aggregation over the intended subset. The proposed action directly targets the problem described in the scenario.
