SAP-C02 Practice Question: Design Solutions for Organizational Complexity
A company plans to migrate on-premises workloads to AWS. They have 500 VMs and need to ensure consistent network segmentation and security group rules across multiple VPCs in different AWS accounts. The network team uses a centralized hub-and-spoke model with AWS Transit Gateway. Which approach minimizes operational overhead while maintaining security compliance?
⚠ Common exam trap
Many exam-takers confuse AWS Config's detective capabilities (alerting) with Firewall Manager's preventive and automated enforcement, or they underestimate the operational burden of custom scripting (Option B) versus a fully managed service like Firewall Manager.
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
✓
Use AWS Firewall Manager to centrally define and apply security group policies across accounts.
AWS Firewall Manager is the correct choice because it provides a centralized, policy-based approach to define and apply security group rules across multiple accounts and VPCs in an AWS Organization. It integrates with AWS Transit Gateway to enforce consistent network segmentation in a hub-and-spoke model, minimizing operational overhead by automating rule enforcement and compliance without custom scripting or manual periodic checks.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use AWS Config rules to detect non-compliant security groups and send alerts.
Why it's wrong here
Alerts require manual remediation; does not prevent drift.
- ✗
Create a Python script that uses AWS SDK to apply security group rules to each VPC and run it periodically.
Why it's wrong here
Scripting is not scalable and requires constant maintenance.
- ✓
Use AWS Firewall Manager to centrally define and apply security group policies across accounts.
Why this is correct
Firewall Manager automates policy enforcement across all accounts.
- ✗
Use network ACLs instead of security groups to enforce segmentation.
Why it's wrong here
NACLs are stateless and less flexible.
