CLF-C02 Security and Compliance Practice Question

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. A key principle to apply: aWS Firewall Manager centrally manages security policies across an AWS Organization.. 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 uses AWS Organizations to manage multiple accounts. The security team needs to enforce a consistent set of security group rules across all accounts. For example, they want to ensure that no security group in any account allows inbound SSH (port 22) from the internet (0.0.0.0/0). If a non-compliant security group is created, the service should automatically remediate by removing the offending rule or by applying a corrective policy. The company wants a managed AWS service that centrally applies these rules and requires no custom scripting. Which AWS service should the security team use?

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 a centralized, managed way to apply security group rules across all accounts in an AWS Organization. It can automatically detect non-compliant security groups (e.g., those allowing SSH from 0.0.0.0/0) and remediate them by removing the offending rule or applying a corrective policy, all without custom scripting.

Key principle: AWS Firewall Manager centrally manages security policies across an AWS Organization.

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 Firewall Manager

    Why this is correct

    Correct. AWS Firewall Manager enables central management of security group rules across multiple accounts in AWS Organizations. It can automatically enforce policies and remediate non-compliant resources, exactly as required.

    Related concept

    AWS Firewall Manager centrally manages security policies across an AWS Organization.

  • AWS Config

    Why it's wrong here

    Incorrect. AWS Config can evaluate resource configurations against rules and detect non-compliant security groups, but it does not provide automatic remediation out of the box without custom AWS Config rules and Lambda functions. The scenario requires a managed service that automatically enforces and remediates, which is a core capability of Firewall Manager.

    When this WOULD be correct

    AWS Config would be correct if the question required detecting non-compliant security group rules across accounts and optionally triggering custom remediation via AWS Systems Manager Automation or Lambda, but explicitly allowed custom scripting for remediation.

  • AWS Organizations

    Why it's wrong here

    Incorrect. AWS Organizations is a service for centrally managing multiple AWS accounts, including consolidated billing and policy-based management (Service Control Policies), but it does not directly enforce security group rules across accounts. Security group policies are handled by Firewall Manager.

    When this WOULD be correct

    A company needs to centrally manage multiple AWS accounts, apply service control policies (SCPs) to restrict permissions, or consolidate billing. In such a scenario, AWS Organizations would be the correct service.

  • AWS Shield Advanced

    Why it's wrong here

    Incorrect. AWS Shield Advanced is a managed DDoS protection service. It does not have capabilities to enforce or remediate security group rules. The scenario is about controlling inbound SSH access, not protecting against distributed denial-of-service attacks.

    When this WOULD be correct

    A company wants to protect its applications running on AWS from DDoS attacks, requiring advanced detection and mitigation, including cost protection against scaling charges. AWS Shield Advanced would be the correct choice.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.

AWS Firewall ManagerCorrect answer

Why this is correct

Correct. AWS Firewall Manager enables central management of security group rules across multiple accounts in AWS Organizations. It can automatically enforce policies and remediate non-compliant resources, exactly as required.

AWS ConfigWrong answer — click to see why

Why this is wrong here

AWS Config can detect non-compliant security group rules via managed rules, but it cannot automatically remediate them without custom AWS Config rules and custom Lambda functions, which violates the 'no custom scripting' requirement.

★ When this WOULD be the correct answer

AWS Config would be correct if the question required detecting non-compliant security group rules across accounts and optionally triggering custom remediation via AWS Systems Manager Automation or Lambda, but explicitly allowed custom scripting for remediation.

Why candidates choose this

Candidates often associate AWS Config with compliance monitoring and think its auto-remediation feature (SSM Automation) can fix rules without scripting, but that still requires custom automation documents, not a managed service.

AWS OrganizationsWrong answer — click to see why

Why this is wrong here

AWS Organizations is a service for centrally managing multiple AWS accounts, but it does not provide security group rule enforcement or remediation. It lacks the ability to automatically detect and fix non-compliant security groups.

★ When this WOULD be the correct answer

A company needs to centrally manage multiple AWS accounts, apply service control policies (SCPs) to restrict permissions, or consolidate billing. In such a scenario, AWS Organizations would be the correct service.

Why candidates choose this

Candidates may think that since AWS Organizations manages accounts centrally, it can also enforce security rules across accounts, but it only provides policy-based guardrails (SCPs) for IAM actions, not for security group configurations.

AWS Shield AdvancedWrong answer — click to see why

Why this is wrong here

AWS Shield Advanced is a managed DDoS protection service, not a service for centrally enforcing security group rules across accounts. It does not provide security group compliance or remediation capabilities.

★ When this WOULD be the correct answer

A company wants to protect its applications running on AWS from DDoS attacks, requiring advanced detection and mitigation, including cost protection against scaling charges. AWS Shield Advanced would be the correct choice.

Why candidates choose this

Candidates may confuse 'security' services and think Shield Advanced provides broader security management, or they may misread the question as focusing on network security rather than compliance enforcement.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse AWS Config's compliance evaluation and remediation capabilities with Firewall Manager's centralized policy enforcement, forgetting that Config requires custom scripting for automatic remediation, whereas Firewall Manager provides it as a managed service.

Trap categories for this question

  • Scenario analysis trap

    Incorrect. AWS Config can evaluate resource configurations against rules and detect non-compliant security groups, but it does not provide automatic remediation out of the box without custom AWS Config rules and Lambda functions. The scenario requires a managed service that automatically enforces and remediates, which is a core capability of Firewall Manager.

Detailed technical explanation

How to think about this question

AWS Firewall Manager uses AWS Organizations as its underlying structure to apply security group policies across member accounts. When a policy is defined (e.g., 'deny SSH from 0.0.0.0/0'), Firewall Manager continuously monitors all security groups in the organization and automatically removes non-compliant rules or attaches a compliant baseline security group to resources. This works by leveraging AWS Config's compliance evaluation under the hood, but Firewall Manager handles the remediation logic natively, eliminating the need for custom code.

KKey Concepts to Remember

  • AWS Firewall Manager centrally manages security policies across an AWS Organization.
  • It can enforce security group rules, WAF rules, Shield Advanced, and Route 53 Resolver DNS Firewall.
  • Firewall Manager automatically remediates non-compliant resources without custom scripting.
  • It ensures consistent security posture across multiple AWS accounts.

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

AWS Firewall Manager centrally manages security policies across an AWS Organization.

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.
