Show Suggested Answer

Suggested Answer: C

For the configuration of data unloading in Snowflake, the valid option among the provided choices is 'C.' This is because Snowflake supports unloading data into Google Cloud Storage using the COPY INTO <location> command with specific configurations. The configurations listed in option C, such as Parquet file format with UTF-8 encoding and gzip compression, are all supported by Snowflake. Notably, Parquet is a columnar storage file format, which is optimal for high-performance data processing tasks in Snowflake. The UTF-8 file encoding and gzip compression are both standard and widely used settings that are compatible with Snowflake's capabilities for data unloading to cloud storage platforms. Reference:

Option B is alright, but Latin-1 encoding? What is this, the 90s? Let's stay modern with UTF-8 for text data.

I'm not sure, but I think option A could also be valid with Snowflake internal location and UTF-8 encoding.

Option A is the way to go. Keeping everything within Snowflake's internal storage is the simplest and most secure approach.
