Snowflake SnowPro Certification Practice Test

Which file compression methods can be automatically detected by Snowflake?

1. BROTLi and Zstandard

2. GZIP, BZIP2, Deflate, and Raw_Deflate

3. BZIP and RAR

4. XZ and LZ4

The correct answer is: GZIP, BZIP2, Deflate, and Raw_Deflate

Snowflake is designed to automatically detect certain file compression methods during data loading operations, which simplifies the process for users. The correct selection includes GZIP, BZIP2, Deflate, and Raw_Deflate. GZIP is widely used due to its effective compression and compatibility with various systems, making it a common choice for data storage and transfer. BZIP2 provides a higher compression ratio than GZIP but can be slower. Deflate and Raw_Deflate are also compression formats often utilized for their balance between speed and compression efficiency. This automatic detection feature of these methods allows users to load compressed files into Snowflake without needing to manually decompress them beforehand, streamlining the data ingestion process. The other methods listed in the choices either do not belong to the recognized set of formats for automatic detection by Snowflake or are less common in data handling within the Snowflake ecosystem.
