- A
AWS WAF
Why wrong: WAF creates firewall rules for specific web applications in a single account and region. It does not centrally manage rule sets across multiple accounts.
- B
AWS Security Hub
Why wrong: Security Hub aggregates security findings across accounts. It does not deploy or enforce firewall rules and WAF policies across accounts.
- C
AWS Firewall Manager
Firewall Manager is a security management service that centrally deploys and enforces WAF rules, Shield Advanced protections, VPC security groups, and Network Firewall policies across all accounts in an AWS Organisation.
- D
AWS Shield Advanced
Why wrong: Shield Advanced provides enhanced DDoS protection for specific resources. While Firewall Manager can deploy Shield Advanced, it is not itself the centralised policy management service.
AWS Firewall Manager for Centralized Security Policy Management
This CLF-C02 practice question tests your understanding of security and compliance. 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 manages 15 AWS accounts and wants to centrally deploy and enforce consistent AWS WAF rules, security groups, and Shield Advanced protections across all accounts and regions from a single administrator account. Which AWS service provides this centralised security policy management?
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
AWS Firewall Manager
AWS Firewall Manager is the correct service because it provides centralized security policy management across multiple AWS accounts and regions. It allows an administrator to define and enforce AWS WAF rules, security group rules, and Shield Advanced protections from a single administrator account, ensuring consistent compliance across all accounts in an AWS Organization.
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
The trap here is that candidates confuse AWS WAF (a resource-level protection service) with Firewall Manager (a multi-account policy management service), leading them to select AWS WAF instead of the centralized governance solution.
Detailed technical explanation
How to think about this question
AWS Firewall Manager uses AWS Organizations to centrally configure and apply security policies across member accounts. It supports policy types including AWS WAF rules (e.g., rate-based rules, managed rule groups), security group common and content audit policies, and Shield Advanced protections. When a policy is updated, Firewall Manager automatically propagates changes to all accounts and regions within the defined scope, ensuring consistent enforcement without manual intervention.
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.
TExam Day Tips
- 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
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.

Same concept, more angles
1 more ways this is tested on CLF-C02
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 uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
medium- A.AWS Config
- ✓ B.AWS Firewall Manager
- C.Amazon GuardDuty
- D.AWS Identity and Access Management (IAM)
Why B: AWS Firewall Manager is the correct service because it provides centralized management of firewall rules across all accounts in AWS Organizations. It can enforce a common security group rule to deny SSH access from 0.0.0.0/0, automatically apply this policy to new VPCs and security groups, and remediate non-compliant existing security groups by removing or replacing violating rules. This meets the requirement for both proactive enforcement and automated remediation at scale.
