Which Snowflake object executes code outside Snowflake, i.e., a remote service?

• A. External Script
• B. External Job
• C. External Function
• D. External Function Integration

Answer: (C)

External Function is the Snowflake object that executes code outside Snowflake. When you define one, you link it to an External Function Integration that points to a remote endpoint (such as AWS Lambda, Google Cloud Functions, Azure Functions, or a custom HTTP service). Invoking the function sends the input to that remote service, which runs the code externally and returns the result back to Snowflake. The External Function Integration itself is just the connection setup and credentials used to reach the remote service, not the code execution.
