What determines the data model size limits on a dataset when large dataset storage format is enabled?

• A. Power BI Premium 10 GB size limit.
• B. Power BI Premium capacity size or the maximum size set by the administrator.
• C. There are no size limits if large dataset storage format is enabled.
• D. The size is determined by the number of users accessing the dataset.

Answer: (B)

The key idea is that large dataset storage format expands how big a model can be, but the ceiling is still defined by the resources available in your Premium capacity and any administrator-imposed limits. When you enable this format, the dataset benefits from more efficient storage and can grow larger, but you’re not free to exceed what the Premium capacity can support. If the capacity has more headroom, larger datasets are possible; if an admin has set a maximum dataset size for a workspace or policy, that cap applies as well. The number of users accessing the dataset doesn’t directly set its maximum size, and there are indeed practical limits beyond zero, so the size isn’t unlimited or fixed at an old 10 GB rule.
