You have a parent folder with department subfolders. Each department manages its project and VPC and can create VPC firewall rules. VPCs must be isolated so no traffic flows between them, but departments should manage intra-VPC rules. How do you enforce a global deny-from-any-other-VPC while delegating intra-VPC allows to the department folders?

The correct option uses hierarchical firewall policies with gotonext to achieve the desired isolation and delegation. A high-priority gotonext rule allows intra-VPC traffic to bypass the hierarchical policy and be evaluated by VPC network firewall rules, which departments can manage. A lower-priority rule then blocks all other traffic, ensuring inter-VPC isolation. Creating a single VPC firewall rule with priority 0 or 1000 to block all traffic would prevent intra-VPC communication and override department-managed rules, failing to meet the requirements. Using allow instead of gotonext for the high-priority rule would prevent further evaluation by VPC network firewall rules, limiting departmental control.
