Show answer and explanation
Correct answer: A
Explanation
To identify the location of a table in Databricks, the DESCRIBE DETAIL command is the most appropriate method. It provides detailed metadata about the table, including its physical storage path. Other options do not provide the required level of detail or are not applicable for locating a specific table.
- A. Correct.
The DESCRIBE DETAIL command provides detailed metadata about the table, including its storage location, making it the correct method to identify the table's location.
- B. Incorrect.
DBFS metadata does not directly provide table-specific location details, so this is not a valid option.
- C. Incorrect.
The default storage location of the workspace is not specific to individual tables, so this is not a reliable method to identify the location of a table.
- D. Incorrect.
The SHOW TABLES command lists tables in the database but does not provide detailed metadata, including the table's location, making this incorrect.
