The correct firewall policies are data, mgmt, and intercluster. These terms are commonly used in firewall rules and configurations. A firewall policy typically involves defining rules for data traffic, management traffic, and traffic between clustered nodes, which correspond to the options data, mgmt, and intercluster respectively. The options cluster and node do not represent standard firewall policy categories. Therefore, the three correct firewall policies are data, mgmt, and intercluster.
