SAP-C02 Practice Question: Design Solutions for Organizational Complexity
A company with multiple AWS accounts wants to centrally manage network security policies. The security team needs to inspect all traffic between VPCs in different accounts and block malicious traffic. Which solution is MOST operationally efficient?
⚠ Common exam trap
A common mix-up: candidates assume AWS Transit Gateway with a Gateway Load Balancer is the most operationally efficient because it provides centralized inspection, but they overlook the automated policy management and cross-account deployment capabilities of AWS Firewall Manager, which reduces operational overhead significantly for multi-account environments.

Correct answer & explanation
✓
AWS Network Firewall with AWS Firewall Manager and AWS Resource Access Manager to deploy across accounts.
AWS Network Firewall, combined with AWS Firewall Manager and AWS Resource Access Manager, provides a centralized, policy-based approach to deploy and manage network security rules across multiple accounts and VPCs. Firewall Manager allows you to define common security policies (e.g., domain filtering, intrusion prevention) and automatically apply them to new and existing VPCs, while RAM enables sharing the firewall subnet across accounts. This eliminates the need for manual per-account configuration, making it the most operationally efficient solution for centrally inspecting and blocking malicious traffic between VPCs in different accounts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS PrivateLink to route traffic through a centralized security appliance in a single account.
Why it's wrong here
PrivateLink is for accessing services, not for routing all inter-VPC traffic; managing appliances adds overhead.
- ✗
VPC Peering connections between all VPCs and use security groups to control traffic.
Why it's wrong here
VPC Peering does not provide centralized traffic inspection; security groups are stateful but not designed for inline inspection across many VPCs.
- ✓
AWS Network Firewall with AWS Firewall Manager and AWS Resource Access Manager to deploy across accounts.
Why this is correct
This provides centralized policy management and automatic deployment across accounts with minimal operational effort.
- ✗
AWS Transit Gateway with a centralized inspection VPC using a Gateway Load Balancer.
Why it's wrong here
This requires manual route table updates in each VPC and additional management of the inspection VPC.
