A company's compliance team needs to enforce a policy that all Amazon S3 buckets must have 'Block all public access' enabled. If a bucket is created without this setting, the company wants the policy to be automatically remediated within minutes without manual intervention. The solution must check for compliance continuously and apply the fix automatically. Which AWS service should the company use to meet these requirements?

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 Config with an AWS Config rule and an automatic remediation action

AWS Config can evaluate resource configurations against rules (e.g., 's3-bucket-public-read-prohibited') and automatically trigger a remediation action, such as an SSM Automation document, to fix non-compliant resources like S3 buckets without manual intervention. This matches the requirement.

B

Distractor review

Amazon GuardDuty

Amazon GuardDuty is a threat detection service that identifies suspicious activity and potential security threats using machine learning. It does not evaluate or remediate resource configuration compliance such as S3 bucket public access settings.

C

Distractor review

AWS CloudTrail

AWS CloudTrail records API calls made in the AWS account for auditing, governance, and security analysis. It does not proactively check resource configurations or apply automatic remediation.

D

Distractor review

AWS Identity and Access Management (IAM)

AWS IAM manages users, groups, roles, and policies to control access to AWS services and resources. It does not monitor or enforce configuration compliance on resources like S3 buckets.

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.

Keep practising from the same exam bank, or move into a focused topic page if this question exposed a weak area.

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 Config with an AWS Config rule and an automatic remediation action — AWS Config is the correct service because it continuously evaluates resource configurations against desired policies (Config rules) and can automatically remediate non-compliant resources by triggering remediation actions, such as an AWS Systems Manager Automation document or an AWS Lambda function. In this scenario, AWS Config would detect any S3 bucket that does not have 'Block all public access' enabled and automatically apply the setting. Amazon GuardDuty is a threat detection service that monitors for malicious activity, not for configuration compliance. AWS CloudTrail records API activity for auditing but does not evaluate or remediate configurations. AWS IAM manages user permissions and access controls, not resource configuration enforcement.
