Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
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
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
AWS Firewall Manager
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.
B
Distractor review
AWS Config
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.
C
Distractor review
AWS Organizations
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.
D
Distractor review
AWS Shield Advanced
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.
Common exam trap
Common exam trap: answer the scenario, not the keyword
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.
Technical deep dive
How to think about this question
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.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
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?
FAQ
Questions learners often ask
What does this CLF-C02 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: AWS Firewall Manager — AWS Firewall Manager is a security management service that allows you to centrally configure and manage firewall rules across accounts and resources in AWS Organizations. It can enforce policies for security groups, AWS WAF rules, AWS Shield Advanced protections, and AWS Network Firewall rules. In this scenario, the security team can create a security group policy that blocks SSH from the internet; Firewall Manager will automatically monitor all accounts and apply the policy, remediating any non-compliant security groups. AWS Config can audit and notify but does not automatically remediate without custom rules. AWS Organizations provides the account management structure but not the security policy enforcement. AWS Shield Advanced is focused on DDoS protection. Therefore, Firewall Manager is the correct choice.
