Which statement accurately describes Snowflake network policies?

• A. They optimize query performance
• B. They provide options for managing network configurations for the Snowflake service
• C. They enforce data retention policies
• D. They manage user authentication methods

Answer: (B)

Snowflake network policies control where and how users can connect to Snowflake by defining allowed networks and connectivity rules. This means you can specify IP addresses or ranges that are permitted, enforce secure transport, and attach these rules to specific users or roles. The reason this description fits best is that network policies are about the network access layer for the Snowflake service, shaping who can reach the account rather than how data is processed or stored. They aren’t about query performance, which depends on warehouse sizing and query optimization; they don’t set data retention policies, which govern how long data is kept; and they aren’t the method for choosing authentication approaches, though they work alongside authentication to restrict login origins. In practice you create a network policy, define the allowed networks, and apply it to users; login attempts from unapproved networks are blocked, enhancing security while permitting access from trusted locations. They can also support private connectivity options to further control how traffic reaches Snowflake.
