Show answer and explanation
Correct answer: A
Explanation
The DESCRIBE DETAIL command is the correct way to identify a table's location in Databricks. It provides detailed metadata, including the physical storage location of the table. Other options either do not provide the location or are not standard practices for retrieving this information.
- A. Correct.
Correct: The DESCRIBE DETAIL command provides metadata about a table, including its location. This is the most direct and reliable method.
- B. Incorrect.
Incorrect: While the Delta Lake transaction log contains metadata about the table, querying it directly for the location is not a standard practice and requires advanced knowledge of the Delta log structure.
- C. Incorrect.
Incorrect: The Databricks workspace UI does not directly display the physical location of the table. It provides table metadata but not the location details.
- D. Incorrect.
Incorrect: The SHOW TABLES command displays a list of tables but does not include detailed metadata such as the table's location.
