Quick Answer
The answer is AWS Firewall Manager, as it is the only service designed to centrally manage security group rules across multiple accounts within AWS Organizations. Firewall Manager enforces a common set of security group rules and security policies across all accounts and VPCs, ensuring consistent compliance without requiring manual per-account configuration. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this question tests your understanding of governance versus deployment: AWS Config only audits rules, CloudFormation StackSets deploys resources but lacks ongoing enforcement, and IAM Policies control permissions, not network traffic. A common trap is confusing Config’s compliance checks with Firewall Manager’s active enforcement. Remember the mnemonic “Firewall Manager Fights for Force” — it actively forces rules across accounts, while other services merely report or deploy.
This ANS-C01 practice question tests your understanding of network security, compliance and governance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 wants to centrally manage and enforce VPC security group rules across multiple accounts in AWS Organizations. Which AWS service should be used?
AWS Config
Why wrong: Config is detective, not enforcement.
AWS CloudFormation StackSets
Why wrong: StackSets deploy stacks, not enforce ongoing rules.
AWS Firewall Manager
Firewall Manager centrally enforces security group rules.
IAM Policies
Why wrong: IAM policies control permissions, not security group configurations.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS Firewall Manager
Option B is correct because AWS Firewall Manager allows central management of security group rules across accounts. Option A is wrong because AWS Config is for compliance, not enforcement. Option C is wrong because AWS CloudFormation StackSets can deploy resources but not enforce ongoing compliance. Option D is wrong because IAM Policies don't configure security groups.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company wants to centrally manage and enforce security rules for all VPCs in a multi-account environment. Which AWS service should be used?
easyWhy C: AWS Firewall Manager is the correct choice because it provides centralized management of firewall rules across multiple accounts and VPCs in an AWS Organization. It allows you to enforce a common set of security policies, such as AWS WAF rules, AWS Shield Advanced protections, and VPC security group rules, ensuring consistent governance across all VPCs in the multi-account environment.
Variation 2. Which AWS service can be used to centrally manage and enforce security group rules across multiple accounts in AWS Organizations?
easyWhy B: Option C is correct because AWS Firewall Manager allows centralized management of security groups across accounts. Option A is wrong because AWS Config evaluates but does not enforce. Option B is wrong because AWS Shield Advanced is for DDoS. Option D is wrong because IAM is for user permissions.
