SnowPro Core Certification — Question 330

Which of the following describes external functions in Snowflake?

Answer options

• A. They are a type of User-defined Function (UDF).
• B. They contain their own SQL code.
• C. They call code that is stored inside of Snowflake.
• D. They can return multiple rows for each row received.

Correct answer: A

Explanation

The correct answer is A, as external functions in Snowflake are indeed categorized as User-defined Functions (UDFs). Options B and C are incorrect because external functions do not contain their own SQL code nor do they call code stored inside Snowflake; instead, they execute code hosted outside of Snowflake. Option D is also wrong since external functions typically return a single result for each input.
