- A
Project-level VPC firewall rules
Project teams can add their own rules using VPC firewall rules (or project-level hierarchical policies).
- B
Network firewall policy
Why wrong: Network firewall policies are similar to VPC firewall rules but are applied to a specific network; they are not used for organization-wide baseline.
- C
Shared VPC
Why wrong: Shared VPC allows sharing networks but does not enforce firewall rules across projects.
- D
Cloud Armor security policy
Why wrong: Cloud Armor is for WAF, not for baseline firewall rules.
- E
Organization-level hierarchical firewall policy
This enforces baseline rules across all projects.

PCSE Configuring Network Security Practice Question
This PCSE practice question tests your understanding of configuring network security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A security engineer is designing a network security architecture for a multi-project environment. They need to enforce a baseline set of firewall rules across all projects in the organization, but allow individual project teams to add their own specific rules. Which TWO components 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
✓
Project-level VPC firewall rules
Hierarchical firewall policies can be applied at the organization level to enforce baseline rules. These policies are inherited by all projects. Individual project teams can then create their own VPC firewall rules (or project-level hierarchical policies) that are evaluated after the org-level policies, allowing them to add specific rules without overriding the baseline.
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
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
