CV0-004 Security Practice Question
This CV0-004 practice question tests your understanding of security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 company is deploying a web application on GCP and needs to protect against OWASP Top 10 threats and DDoS attacks. Which THREE services should be combined to provide comprehensive protection?
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
✓
Cloud Load Balancing
Cloud Load Balancing (A) is correct because it distributes incoming traffic across multiple backend instances, providing inherent DDoS resilience by absorbing and scaling with attack traffic. It also integrates directly with Cloud Armor to enforce OWASP Top 10 web application firewall (WAF) rules, such as SQL injection and XSS protections, at the edge before traffic reaches the application.
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
The trap here is that candidates often confuse Cloud NAT or Cloud VPN as security services for inbound traffic, but they are designed for outbound connectivity and encrypted tunnels, not for application-layer threat detection or DDoS mitigation.
Detailed technical explanation
How to think about this question
Cloud Armor uses a rules engine that evaluates HTTP(S) requests against pre-configured WAF rules (e.g., OWASP ModSecurity Core Rule Set) and can also apply rate limiting and IP blacklisting to mitigate Layer 7 DDoS attacks. Cloud CDN caches static content at Google's edge locations, reducing origin load and absorbing volumetric attacks by serving cached responses, while Cloud Load Balancing provides global anycast IPs that distribute traffic across multiple regions, further diluting attack impact.
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.
TExam Day Tips
- 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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
