An organization has multiple VPC networks in a project and wants to centrally manage firewall rules across all networks using a single set of rules. Which approach should they take?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use hierarchical firewall policies at the folder level
Firewall rules are per network. To centrally manage rules, you can use hierarchical firewall policies (part of VPC Firewall Policies) applied at the organization or folder level, which override network-specific rules.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use firewall rules with global scope
Why it's wrong here
Firewall rules are already global per VPC, but not across multiple VPCs.
- ✗
Create a single VPC network and use subnetting
Why it's wrong here
This consolidates networks but may not meet isolation requirements.
- ✓
Use hierarchical firewall policies at the folder level
Why this is correct
Hierarchical firewall policies apply to all networks under a folder, enabling central management.
- ✗
Use shared VPC and apply firewall rules to the host project
Why it's wrong here
Shared VPC allows central management but rules are still per network.
