The source team's new rows are in a relational database but analysts want a nightly incremental warehouse load. The team plans to implement this change: Use a source change marker or watermarked extraction in an orchestrated pipeline. Which result best verifies the intended outcome?
Incremental ingestion reduces unnecessary movement by selecting newly changed records. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: A new ingestion run succeeds under the correct identity and shows recently added source records. It does not demonstrate the specific required result: After two runs the destination contains the new records without duplicating previously loaded keys.
That observation would verify a different goal: Two consumers read the same authoritative records and changes are reflected through the supported access path. It does not demonstrate the specific required result: After two runs the destination contains the new records without duplicating previously loaded keys.
That observation would verify a different goal: A test user runs the authorized dataflow while a user without connection access is denied. It does not demonstrate the specific required result: After two runs the destination contains the new records without duplicating previously loaded keys.

A single lakehouse must expose cleaned Delta facts to multiple governed Power BI models. Which implementation decision best addresses the stated requirement?
OneLake is the common physical analytics storage used by Fabric workloads. The proposed action directly targets the problem described in the scenario.
Use a lakehouse for curated historical Delta tables and Eventhouse for stream-oriented data. is an approach for a different requirement: Store selection should follow workload latency and query characteristics rather than one-size-fits-all storage. In the present case, oneLake is the common physical analytics storage used by Fabric workloads.
Evaluate Direct Lake over supported OneLake Delta tables, with capacity and security requirements checked. is an approach for a different requirement: Direct Lake loads selected Delta columns into a VertiPaq cache without a full Import processing cycle. In the present case, oneLake is the common physical analytics storage used by Fabric workloads.
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, oneLake is the common physical analytics storage used by Fabric workloads.
A source includes integer order quantities but a transformation converts them to floating point for every operation. The team plans to implement this change: Use appropriate integer and fixed-precision decimal types for quantities and monetary amounts. Which result best verifies the intended outcome?
Data-type selection affects numerical accuracy and safe aggregation in analytical pipelines. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: Totals match independently computed sales and returns measures at each month. It does not demonstrate the specific required result: Reconciled invoice totals match the exact expected currency precision.
That observation would verify a different goal: No out-of-period transaction contributes to the returned totals. It does not demonstrate the specific required result: Reconciled invoice totals match the exact expected currency precision.
That observation would verify a different goal: Sales totals reconcile and a product dimension filter propagates to the intended fact rows. It does not demonstrate the specific required result: Reconciled invoice totals match the exact expected currency precision.
A KQL report needs an hourly trend of warning counts from timestamped events. Which implementation decision best addresses the stated requirement?
Time binning groups many nearby timestamps into a shared interval. The proposed action directly targets the problem described in the scenario.

A SQL warehouse has an existing dimension table and a modeling team proposes creating a second copy in every workspace. Which implementation decision best addresses the stated requirement?
Reusing governed data reduces divergent definitions and unnecessary data duplication. The proposed action directly targets the problem described in the scenario.
Enable a supported Eventhouse data availability/integration path to OneLake as appropriate. is an approach for a different requirement: Eventhouse and OneLake integration can make compatible event data available for cross-workload analytics. In the present case, reusing governed data reduces divergent definitions and unnecessary data duplication.
Use a source change marker or watermarked extraction in an orchestrated pipeline. is an approach for a different requirement: Incremental ingestion reduces unnecessary movement by selecting newly changed records. In the present case, reusing governed data reduces divergent definitions and unnecessary data duplication.
Inspect and repair the underlying Fabric connection and its source access before changing report visuals. is an approach for a different requirement: Connection identity and endpoint validity control whether fresh source data can be retrieved. In the present case, reusing governed data reduces divergent definitions and unnecessary data duplication.
A warehouse stores SKU cost history with effective date ranges and needs the right cost for each order. Which implementation decision best addresses the stated requirement?
Temporal joins require valid time predicates to prevent duplicate version matches. The proposed action directly targets the problem described in the scenario.
Deduplicate using the composite business key and a deterministic source-priority rule. is an approach for a different requirement: Business-key deduplication addresses logical duplicates that may differ in nonkey attributes. In the present case, temporal joins require valid time predicates to prevent duplicate version matches.
Filter transaction rows on the relevant typed date range before aggregation. is an approach for a different requirement: A WHERE predicate changes the qualifying row set; a descriptive title does not. In the present case, temporal joins require valid time predicates to prevent duplicate version matches.
Use a LEFT OUTER JOIN from Product to an appropriate aggregated Sales result. is an approach for a different requirement: A left join preserves unmatched dimension members needed to identify zero-activity entities. In the present case, temporal joins require valid time predicates to prevent duplicate version matches.
