We can enable it on both database and table levels. I think Microsoft just want to ask for default settings with them. on database level, default option is "Apply to existing tables" which will map all tables to Onelake but don't include any old data. same issue when we try it on table level though UI.

The correct answer is: D. both new data and existing data in the eventhouse When you enable OneLake availability for an eventhouse, you have the option to apply this setting to existing tables by selecting the "Apply to existing tables" option. This means that both new data and existing data will be available in OneLake. As stated in the article: "When turning on the feature, you can also choose to apply this option to existing tables by selecting the Apply to existing tables option, to include historic backfill." This explains why both new and existing data will be copied to OneLake. Check this link: https://learn.microsoft.com/en-us/fabric/real-time-intelligence/event-house-onelake-availability#how-it-works

When you enable OneLake availability for an eventhouse, you have the option to apply this setting to existing tables, which includes the data already present in those tables. This means that both new data (data added after enabling OneLake availability) and existing data (data that was already in the eventhouse at the time of enabling OneLake availability) will be available in OneLake. As the article states: "When turning on the feature, you can also choose to apply this option to existing tables by selecting the Apply to existing tables option, to include historic backfill." This indicates that enabling OneLake availability can include the historical data, meaning the existing data, in addition to any new data added afterwards.

I think it used to be that only new data was available but documentation now says otherwise: https://learn.microsoft.com/en-us/fabric/real-time-intelligence/event-house-onelake-availability#how-it-works When you turn availability back on, all data is made available in OneLake, including historic backfill. I vote for D then

If we strictly follow the documentation's explanation that only new tables are made available in OneLake, then your choice E. only new data added to the eventhouse is the most precise answer. ✅ Final Answer: E. only new data added to the eventhouse

Selected Answer: D
The correct answer is: D. both new data and existing data in the eventhouse Explanation: When you enable OneLake availability for an eventhouse in Microsoft Fabric, all existing data within the eventhouse, along with any new data added afterward, is copied to OneLake. This ensures that users can access both past and future data through OneLake file explorer. This means that enabling OneLake availability makes the entire dataset in the eventhouse visible in OneLake, not just new data moving forward.

You can turn on OneLake availability at the database or table level. When enabled at the database level, all new tables and their data are made available in OneLake. When turning on the feature, you can also choose to apply this option to existing tables by selecting the Apply to existing tables option.
