The lakehouse holds curated historical dimensions while a live event feed arrives continually. Which implementation decision best addresses the stated requirement?
Store selection should follow workload latency and query characteristics rather than one-size-fits-all storage. The proposed action directly targets the problem described in the scenario.
Keep the curated tables in OneLake and use compatible semantic-model access modes. is an approach for a different requirement: OneLake is the common physical analytics storage used by Fabric workloads. In the present case, store selection should follow workload latency and query characteristics rather than one-size-fits-all storage.
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, store selection should follow workload latency and query characteristics rather than one-size-fits-all storage.
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, store selection should follow workload latency and query characteristics rather than one-size-fits-all storage.
A device operations dashboard queries streaming logs using a SQL GROUP BY against a KQL database. Which implementation decision best addresses the stated requirement?
KQL supports time-aware event exploration and summarize aggregations on KQL data. The proposed action directly targets the problem described in the scenario.
Use KQL summarize count() by DeviceId followed by top ordering. is an approach for a different requirement: KQL summarize groups event records and top limits ordered results. In the present case, kQL supports time-aware event exploration and summarize aggregations on KQL data.
Write a T-SQL query using SUM and GROUP BY Region with the appropriate filters. is an approach for a different requirement: SQL grouping computes measures over the chosen set of grouping keys. In the present case, kQL supports time-aware event exploration and summarize aggregations on KQL data.
Use Fabric's Visual query editor for the supported select, filter and aggregate operations. is an approach for a different requirement: The visual editor represents common relational operations without requiring typed SQL. In the present case, kQL supports time-aware event exploration and summarize aggregations on KQL data.

A security group wants time-series inspection followed by downstream batch analytics. The team plans to implement this change: Use Eventhouse for fast event exploration and supported OneLake integration for downstream consumption. Which result best verifies the intended outcome?
Eventhouse-to-OneLake interoperability can support analysis across real-time and data engineering experiences. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: The model reports the correct current data and telemetry shows the expected Direct Lake execution path. It does not demonstrate the specific required result: The same event batch can be queried in Eventhouse and accessed by an approved downstream lakehouse path.
That observation would verify a different goal: Historical queries and minute-by-minute event queries each meet their respective latency needs. It does not demonstrate the specific required result: The same event batch can be queried in Eventhouse and accessed by an approved downstream lakehouse path.
That observation would verify a different goal: A new committed source value appears in a model query without an Import refresh. It does not demonstrate the specific required result: The same event batch can be queried in Eventhouse and accessed by an approved downstream lakehouse path.
A Fabric team connects a warehouse to a protected database and must avoid individual credentials embedded in queries. Which implementation decision best addresses the stated requirement?
Connections represent managed access to a source rather than putting secrets in every query. The proposed action directly targets the problem described in the scenario.
Set up an authorized connection with approved credentials or identity before attempting transforms. is an approach for a different requirement: Transformation logic cannot make up for a missing data-source permission boundary. In the present case, connections represent managed access to a source rather than putting secrets in every query.
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, connections represent managed access to a source rather than putting secrets in every query.
Use OneLake catalog discovery and inspect item endorsements and permissions. is an approach for a different requirement: Catalog discovery exposes accessible organizational data assets without first moving their contents. In the present case, connections represent managed access to a source rather than putting secrets in every query.
A single lakehouse must expose cleaned Delta facts to multiple governed Power BI models. The team plans to implement this change: Keep the curated tables in OneLake and use compatible semantic-model access modes. Which result best verifies the intended outcome?
OneLake is the common physical analytics storage used by Fabric workloads. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: An authorized T-SQL procedure updates staged data and a reporting view returns intended rows. It does not demonstrate the specific required result: Two authorized semantic models query the curated Delta rows without manual file copies.
That observation would verify a different goal: A new committed source value appears in a model query without an Import refresh. It does not demonstrate the specific required result: Two authorized semantic models query the curated Delta rows without manual file copies.
That observation would verify a different goal: The analyst's SELECT statement returns the correct curated rows without editing Delta files. It does not demonstrate the specific required result: Two authorized semantic models query the curated Delta rows without manual file copies.
A project lead asks for all governed datasets already available to the team before making new copies. The team plans to implement this change: Use OneLake catalog discovery and inspect item endorsements and permissions. Which result best verifies the intended outcome?
Catalog discovery exposes accessible organizational data assets without first moving their contents. 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: The correct endorsed dataset is found and can be opened under the analyst's permissions.
That observation would verify a different goal: The desired active stream appears in the hub and can be selected for an authorized operation. It does not demonstrate the specific required result: The correct endorsed dataset is found and can be opened under the analyst's permissions.
That observation would verify a different goal: An analyst locates both the governed lakehouse item and the required available stream. It does not demonstrate the specific required result: The correct endorsed dataset is found and can be opened under the analyst's permissions.
An engineering group must catalog newly published streaming data alongside batch tables. The team plans to implement this change: Use OneLake catalog for analytical items and Real-Time hub for live streams, matching the resource type. Which result best verifies the intended outcome?
Different discovery surfaces are optimized for stored analytical assets and continuously arriving events. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: The corrected pipeline accepts both expected old and new rows without silent column loss. It does not demonstrate the specific required result: An analyst locates both the governed lakehouse item and the required available stream.

The product dimension contains two rows with the same ProductKey, breaking a one-to-many model. Which implementation decision best addresses the stated requirement?
A one-to-many relationship needs unique key values in its one-side dimension. 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, a one-to-many relationship needs unique key values in its one-side dimension.
Use a conformed date dimension related to the relevant fact date keys. is an approach for a different requirement: Shared dimensions provide consistent slicing across multiple facts when relationships are correctly modeled. In the present case, a one-to-many relationship needs unique key values in its one-side dimension.
Define one fact row per order line and document its business keys and measures. is an approach for a different requirement: Explicit fact grain prevents ambiguous aggregations and duplicate relationships. In the present case, a one-to-many relationship needs unique key values in its one-side dimension.
A company has a many-to-many mapping between salespeople and geographic territories. Which implementation decision best addresses the stated requirement?
Bridge tables represent many-to-many associations while preserving a defined relationship model. The proposed action directly targets the problem described in the scenario.
Design a fact table with foreign keys to conformed dimensions in a star schema. is an approach for a different requirement: A star schema separates measurable facts from descriptive dimension attributes to clarify grain and filtering. In the present case, bridge tables represent many-to-many associations while preserving a defined relationship model.
Join history using business key and applicable effective-date interval, respecting the desired grain. is an approach for a different requirement: Temporal joins require valid time predicates to prevent duplicate version matches. In the present case, bridge tables represent many-to-many associations while preserving a defined relationship model.
Use an appropriate unknown member or left join strategy while separately fixing invalid keys. is an approach for a different requirement: Missing dimension relationships must not silently erase facts from financial totals. In the present case, bridge tables represent many-to-many associations while preserving a defined relationship model.
A developer applies a row-level WHERE clause to the aggregate alias and gets an error. The team plans to implement this change: Use HAVING on the grouped aggregate after GROUP BY. Which result best verifies the intended outcome?
HAVING filters groups based on aggregate expressions, unlike pre-group row filtering. This evidence exercises the actual success condition rather than only confirming that a resource exists.
That observation would verify a different goal: All returned records satisfy the date requirement and excluded rows are absent. It does not demonstrate the specific required result: All returned customer groups exceed the aggregate threshold.
That observation would verify a different goal: The returned product set matches independently evaluated totals at the chosen threshold. It does not demonstrate the specific required result: All returned customer groups exceed the aggregate threshold.
