According to the exam courses answer is C, for a managed table dropped. But, as after Nov'23, UNDROP is introduced and I have test it working with UC managed tables. https://docs.databricks.com/en/sql/language-manual/sql-ref-syntax-ddl-undrop-table.html However, I don't see any official doc says UNDROP related to 'time travel'. So, be aware of the above info; in exam, watch the question carefully if it is updated.

C. is only correct statement. Though the table can be UNDROP in 7 days https://learn.microsoft.com/en-us/azure/databricks/sql/language-manual/sql-ref-syntax-ddl-undrop-table E.

I think E is better answer

E. Since the table is still recoverable from transaction logs.

C : AS SELECT - Managed table Will remove table and data

In Delta Lake, when a DROP TABLE command is executed, it removes both the metadata entry for the table from the catalog and the data in storage associated with that table. Workspace administrators typically have the necessary permissions to drop tables, and unless there are additional protections or retention policies in place, the data is not recoverable through normal operations after the table is dropped.

Drop will usually delete the table structure and data if its managed, hence c
