To help department teams find data relevant to them, which option supports OneLake filtering by grouping workspaces?

• A. Implementing Fabric Workspace's built-in folder hierarchy
• B. Leveraging Fabric Domains
• C. Using Fabric Lakehouse Explorer
• D. Leveraging Fabric Workspace's tagging feature

Answer: (B)

Grouping workspaces with Fabric Domains provides a scalable way to filter OneLake by department or data area. Domains represent organizational boundaries, so you assign each workspace to a domain that matches a team or function. This lets users filter OneLake to see only the workspaces and datasets relevant to their group, improving discoverability and governance across the lake.

Folders organize within a single workspace, but don’t create cross-workspace filtering for OneLake. Lakehouse Explorer is a discovery tool, and tagging helps with ad hoc naming, but Domains are the mechanisms designed to group workspaces for department-wide filtering.
