According to the Network Policies documentation, a network policy can be applied to an account, a security integration, or a user. If there are network policies applied to more than one of these, the most specific network policy overrides more general network policies. The following summarizes the order of precedence:
* Account: Network policies applied to an account are the most general network policies. They are overridden by network policies applied to a security integration or user.
* Security Integration: Network policies applied to a security integration override network policies applied to the account, but are overridden by a network policy applied to a user.
* User: Network policies applied to a user are the most specific network policies. They override both accounts and security integrations.
Therefore, if both the account_level and user_level network policies are defined, the user_level policy will take effect and the account_level policy will be ignored. The other options are incorrect because:
* The account_level policy will not override the user_level policy, as explained above.
* The user_level network policies will be supported, as they are part of the network policy feature.
* A network policy error will not be generated, as there is no conflict between the account_level and user_level network policies.
