Quick Answer
The answer is AWS Firewall Manager, AWS Network Firewall, and Service Control Policies. This combination works because Firewall Manager provides centralized network security enforcement across AWS Organizations by automating firewall rule deployment, AWS Network Firewall delivers deep packet inspection and stateful filtering at the VPC level, and Service Control Policies (SCPs) enforce guardrails that restrict or allow actions across all accounts, ensuring no account can bypass the security posture. On the AWS Certified Advanced Networking Specialty ANS-C01 exam, this scenario tests your understanding of how to architect a defense-in-depth strategy for multi-account environments, often appearing as a trap where candidates confuse AWS Config (which only monitors compliance) or Security Groups (which are per-resource) with actual enforcement tools. A useful memory tip: think of Firewall Manager as the “orchestrator,” Network Firewall as the “inspector,” and SCPs as the “bouncer” — together they enforce, inspect, and restrict.
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 is designing a multi-account architecture using AWS Organizations. They want to centrally manage and enforce network security policies across all accounts. Which THREE services or features should they use together to achieve this? (Choose THREE.)
AWS Network Firewall
Provides stateful firewall capabilities.
Service Control Policies (SCPs)
Enforce policies at the organization level.
Security Groups
Why wrong: Per-resource, not centrally managed.
AWS Config
Why wrong: Monitors compliance but does not enforce.
AWS Firewall Manager
Central management of firewall rules across accounts.
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 Network Firewall
Options A, C, and D are correct. AWS Firewall Manager (A) centrally manages firewall rules. AWS Network Firewall (C) provides stateful inspection. Service Control Policies (D) enforce guardrails. Option B is wrong because AWS Config is for compliance monitoring, not enforcement. Option E is wrong because Security Groups are per-resource.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
