- A
Denial of Service (DoS) testing is permitted as long as it targets only customer-owned IPs.
Why wrong: DoS testing is explicitly prohibited under Google's policy.
- B
All penetration tests require prior approval from Google Cloud support.
Why wrong: Google does not require prior approval for most penetration tests; customers can test their own resources.
- C
Customers can conduct penetration testing without prior approval, but must avoid DoS attacks.
Google allows penetration testing without prior approval for most services, but DoS testing is prohibited.
- D
Penetration testing is only allowed on Compute Engine, not on managed services like Cloud SQL.
Why wrong: The policy applies to most services; customers can test their own resources across many services.
PCSE Supporting Compliance Requirements Practice Question
This PCSE practice question tests your understanding of supporting compliance requirements. 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.
An organization wants to run a penetration test on their Google Cloud environment to validate security controls. According to Google's Acceptable Use Policy, which of the following is true regarding penetration testing?
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
Customers can conduct penetration testing without prior approval, but must avoid DoS attacks.
Google's Acceptable Use Policy allows customers to conduct penetration testing on their own infrastructure without prior approval for most services, but they prohibit denial of service (DoS) testing. Tests must follow the policy guidelines. No prior approval is needed, but DoS testing is forbidden.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.

Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PCSE ACL questions on filtering logic and placement.
