Answer: snowlake

The correct answer is B (snowlake) based on the community discussion and Snowflake documentation. The authenticator parameter in JDBC driver connections defaults to 'snowflake' (though the option is listed as 'snowlake' in the choices, which appears to be a typo for 'snowflake'). This is confirmed by the Snowflake documentation link provided in the discussion, which shows that when no authenticator is specified, the default is the Snowflake-native authentication. Options C (username_password_mfa) and D (snowflake_jwt) are valid authentication methods but are not the default - they must be explicitly specified. Option A (externalbrowser) is for OAuth/browser-based authentication and is also not the default. The community consensus strongly supports B with 100% agreement across all responses.
