- A
Create a hierarchical firewall policy at the organization level
Hierarchical policies are inherited and cannot be overridden by lower-level rules.
- B
Create a network firewall policy and attach it to each VPC network
Why wrong: Network firewall policies are per VPC and can be overridden by VPC firewall rules in that network.
- C
Use Cloud Armor security policies with the load balancers
Why wrong: Cloud Armor applies to load balancers, not VPC networks directly.
- D
Use VPC firewall rules with tags applied to all VMs across projects
Why wrong: VPC firewall rules are per project and can be overridden or deleted by project owners.

PCSE Configuring Network Security Practice Question
This PCSE practice question tests your understanding of configuring network security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization has multiple VPC networks in different projects. They need to centrally manage firewall rules that apply to all VPCs in the organization and ensure that project owners cannot override them. Which solution should they use?
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
✓
Create a hierarchical firewall policy at the organization level
Hierarchical firewall policies can be applied at the organization or folder level and are inherited by all VPC networks. They cannot be overridden by lower-level firewall rules. This is the correct solution for centralized, unoverrideable rules. Network firewall policies are scoped to a single VPC network.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
