Explanation:

Scenario:
Semantic model contains a measure: TotalSalesAmount.
This measure returns sales revenue translated into a selected currency.
Requirement: Format the result using the correct currency symbol dynamically.
Analysis:
Dynamic format string in DAX is specifically designed for applying formats (like currency symbols) dynamically based on slicers or calculation context.
WINDOW function # used for windowing calculations, not formatting.
Linguistic schema # used for Q&A natural language, not for formatting.
Field parameter # used to swap fields/measures dynamically, not for formatting.

Step 1: Default permissions when sharing a warehouse in Fabric
When you share a Fabric warehouse (DW1) with a user and assign them default permissions, the user:
Gets Build permission by default.
Build permission allows the user to:
Use the default dataset automatically created for the warehouse.
Build reports and dashboards against that dataset.
It does not grant direct query permissions to the underlying tables or files.
Step 2: Analyze the options
A). Build reports by using the default dataset. #
Correct. Sharing a warehouse gives Build permission on the warehouse's default dataset.
User1 can create Power BI reports but cannot directly query the warehouse via SQL.
B). Read the underlying Parquet files from OneLake.
Incorrect. Access to underlying OneLake files requires Direct Lake storage access or shortcut permissions, not provided by default sharing.
C). Connect to DW1 via the TDS endpoint.
Incorrect. The TDS endpoint is supported by semantic models, not warehouses.
D). Read data from the tables in DW1.
Incorrect. Default permissions do not allow table-level SQL access. They allow using the dataset for reporting.
Step 3: Correct Answer
The only capability User1 has by default is:
A). Build reports by using the default dataset.

The PoC is planned to be completed using a Fabric trial capacity, which implies that users involved in the PoC should be able to try paid features. However, this should be limited to specific security groups involved in the PoC to prevent the entire organization from accessing these features before the trial is proven successful (A). The ability for users to create Fabric items should also be enabled for specific security groups to ensure that only the relevant team members participating in the PoC can create items in the Fabric environment (E).
