The question asks about the purpose of enabling Federated Authentication in Snowflake. Federated Authentication specifically allows users to authenticate through external identity providers using secure single sign-on (SSO), which aligns with option D. The community discussion shows 100% consensus on D, with multiple comments confirming this is correct and referencing Snowflake documentation that explains federated authentication enables SSO through external identity providers. Option A is incorrect because federated authentication doesn't disable other authentication methods - it provides an additional option. Option B is incorrect as federated authentication doesn't enable dual MFA. Option C is incorrect because federated authentication handles identity verification, not network proxy configuration.
