COF-C03 Data Loading, Unloading, and Connectivity Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  COPY INTO

  Why it's wrong here

  The COPY INTO command is used to move data from a stage into a table or from a table into a stage. It does not interact directly with a local file system; it requires the data to already be present in a cloud-accessible stage before the ingestion into a table can begin.

• ✗

  GET

  Why it's wrong here

  The GET command is the functional opposite of the PUT command. It is used to download files from a Snowflake internal stage to a local directory on the user's machine. It is typically used after data has been unloaded from a table into a stage using the COPY INTO command.

• ✓

  PUT

  Why this is correct

  The PUT command is specifically designed to upload files from a local directory to an internal stage. It supports features like automatic compression and parallel uploads, making it the standard tool for getting data into the Snowflake environment before it is finally loaded into a permanent database table.

• ✗

  INSERT

  Why it's wrong here

  The INSERT command is a standard SQL DML operation used to add individual rows or results of a query into a table. It is not designed for bulk file movement or uploading files from a local computer, and using it for large-scale data ingestion is inefficient compared to the COPY command.
