Snowflake SnowPro Certification Practice Test 2026 - Free SnowPro Practice Questions and Study Guide

The correct answer specifies that the auto-encryption standard for newly loaded files in Snowflake is AES encryption, which is a well-established symmetric encryption standard used worldwide. AES, or Advanced Encryption Standard, is considered a secure and efficient method for encrypting data. When Snowflake loads files, it automatically applies this encryption standard to safeguard sensitive information.

While the options mention various key lengths such as 128-bit, 256-bit, and 512-bit, the relevant aspect is that Snowflake defaults to using AES encryption with a key length of 256 bits for the strongest security. However, the distinction of using either a 128-bit or 256-bit key length is related to the specific configuration or usage rather than the standard itself. Snowflake's approach reinforces the platform's commitment to data security by ensuring that any data loaded into it is automatically encrypted, thereby protecting it against unauthorized access.
