Correct Answer: D
To list all network policies available in an account, the correct command isSHOW NETWORK POLICIES.
Network policies in Snowflake are used to define and enforce rules for how users can connect to Snowflake, including IP whitelisting and other connection requirements. TheSHOW NETWORK POLICIEScommand provides a list of all network policies defined within the account, along with their details.
TheDESCRIBE SESSION POLICYandDESCRIBE NETWORK POLICYcommands do not exist in Snowflake SQL syntax. TheSHOW SESSION POLICIEScommand is also incorrect, as it does not pertain to the correct naming convention used by Snowflake for network policy management.
UsingSHOW NETWORK POLICIESwithout any additional parameters will display all network policies in the account, which is useful for administrators to review and manage the security configurations pertaining to network access.
