- A
Configure the Application Load Balancer to send all traffic to the firewall appliance using Proxy Protocol v2.
Why wrong: Proxy Protocol is used for preserving client IP information, not for traffic inspection.
- B
Use AWS Direct Connect to route all traffic through the firewall appliance.
Why wrong: Direct Connect provides dedicated connectivity but does not provide traffic inspection capabilities.
- C
Use AWS Network Firewall to inspect traffic.
Why wrong: AWS Network Firewall is a managed service, but it cannot forward traffic to a third-party appliance in a separate VPC.
- D
Deploy Gateway Load Balancer endpoints in the application VPC and attach them to the firewall appliance in the inspection VPC across multiple Availability Zones.
Gateway Load Balancer allows transparent inspection of traffic by third-party appliances and supports multi-AZ deployment.
Quick Answer
The correct choice is to deploy Gateway Load Balancer endpoints in the application VPC and attach them to the firewall appliance in the inspection VPC across multiple Availability Zones. This architecture satisfies the requirement for traffic inspection by a third-party firewall without a single point of failure because GWLB transparently intercepts and routes all traffic through the firewall appliance while the endpoints in each AZ ensure high availability and fault isolation. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how to decouple inspection from the application path using GWLB, a common pattern for compliance-driven designs. A frequent trap is confusing AWS Network Firewall with third-party appliances—remember that AWS Network Firewall cannot route traffic to a separate VPC. Memory tip: think "GWLB endpoints = inspection on-ramp across AZs" to recall that the endpoints live in the app VPC while the firewall stays isolated.
ANS-C01 Network Security, Compliance and Governance Practice Question
This ANS-C01 practice question tests your understanding of network security, compliance and governance. 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 company runs a web application on EC2 instances behind an Application Load Balancer. The security team requires that all traffic to the application be inspected by a third-party firewall appliance for compliance. The firewall appliance must be deployed in a separate VPC and must inspect traffic without introducing a single point of failure. Which architecture meets these requirements?
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
Deploy Gateway Load Balancer endpoints in the application VPC and attach them to the firewall appliance in the inspection VPC across multiple Availability Zones.
Option B is correct because using Gateway Load Balancer endpoints across multiple Availability Zones with the firewall appliance in a separate VPC allows traffic to be routed through the firewall for inspection while maintaining high availability. Option A is wrong because AWS Network Firewall does not support routing traffic to a third-party appliance in a different VPC. Option C is wrong because Direct Connect does not provide traffic inspection. Option D is wrong because Proxy Protocol does not enable traffic inspection.
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.
