- A
AWS Config
AWS Config is the correct choice because it continuously evaluates resource configurations against desired policies (e.g., S3 bucket encryption and public access) and can automatically remediate non-compliant resources using pre-defined actions, meeting all requirements.
- B
AWS Trusted Advisor
Why wrong: AWS Trusted Advisor inspects AWS environments and provides best practice recommendations (including S3 bucket permissions and encryption) but does not support automatic remediation of non-compliant resources.
- C
AWS IAM Access Analyzer
Why wrong: AWS IAM Access Analyzer helps identify resources shared with external entities (e.g., S3 buckets with public or cross-account access) but does not monitor or enforce encryption settings, nor does it automatically apply corrective actions.
- D
AWS CloudTrail
Why wrong: AWS CloudTrail records API activity for governance and audit but does not monitor resource configurations or automatically enforce compliance rules; it cannot detect or remediate non-compliant S3 bucket settings.
Quick Answer
The answer is AWS Config. This service is the correct choice because it continuously monitors and evaluates the configuration of AWS resources—like S3 buckets—against predefined rules, such as requiring server-side encryption with AWS KMS and blocking public access. When a violation is detected, AWS Config can automatically trigger remediation actions, such as enabling default encryption or removing public bucket policies, using Systems Manager Automation or Lambda functions. On the AWS Certified Cloud Practitioner CLF-C02 exam, this scenario tests your understanding of how to enforce security policies at scale across multiple accounts, often appearing as a question that contrasts AWS Config with services like AWS CloudTrail or IAM. A common trap is choosing S3-specific features like bucket policies, but those lack continuous monitoring and automated remediation. Remember: Config is the cop that enforces the rules, not just the rulebook. Memory tip: “Config corrects configurations” across accounts.
CLF-C02 Security and Compliance Practice Question
This CLF-C02 practice question tests your understanding of security and compliance. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 uses multiple AWS accounts. The security team wants to enforce two requirements for all Amazon S3 buckets: first, server-side encryption must be enabled using AWS KMS; second, no bucket can be publicly accessible. The team needs a service that continuously monitors the configuration of S3 buckets across all accounts, detects when a bucket violates either requirement, and automatically applies corrective actions (such as enabling default encryption or removing public access). Which AWS service should the security team use to meet these requirements?

Correct answer & explanation
AWS Config
AWS Config is the correct service because it provides continuous monitoring, evaluation, and automated remediation of resource configurations across multiple accounts. With AWS Config rules (e.g., managed rules like `s3-bucket-server-side-encryption-enabled` and `s3-bucket-public-read-prohibited`), you can detect noncompliant S3 buckets and trigger AWS Systems Manager Automation documents or Lambda functions to automatically enable default encryption or remove public access. AWS Config also supports multi-account aggregation via an aggregator, allowing the security team to enforce these requirements across all accounts from a single management account.
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 Config's continuous compliance monitoring and automated remediation with AWS Trusted Advisor's advisory checks or AWS IAM Access Analyzer's policy analysis, failing to recognize that only AWS Config provides both detection and automatic corrective actions.
Detailed technical explanation
How to think about this question
AWS Config evaluates resource configurations against desired state defined in Config rules, using a configuration recorder that captures configuration changes and triggers evaluations. For automated remediation, you attach an AWS Systems Manager Automation document (e.g., `AWS-EnableS3BucketEncryption` or `AWS-DisableS3PublicAccess`) to the Config rule, which runs when a resource is marked noncompliant. In a multi-account setup, you must enable AWS Config in each account and use an aggregator in a central account to view compliance across all accounts, ensuring the security team has a single pane of glass.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

Same concept, more angles
2 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 and manages hundreds of AWS accounts. The security policy requires that all Amazon S3 buckets be encrypted using a specific AWS KMS customer-managed key (CMK). The security team wants to automatically detect any S3 bucket that is not encrypted with the required CMK and automatically apply the correct encryption configuration without manual intervention. Which AWS service should the security team use to implement this automated compliance enforcement?
medium- A.Amazon GuardDuty
- ✓ B.AWS Config
- C.AWS CloudTrail
- D.AWS Trusted Advisor
Why B: AWS Config is the correct service because it provides managed rules (e.g., s3-bucket-server-side-encryption-enabled and s3-bucket-kms-encryption-specific-key) that can evaluate whether S3 buckets are encrypted with the required KMS customer-managed key. When a noncompliant bucket is detected, AWS Config can trigger an AWS Lambda function via an Amazon EventBridge rule to automatically apply the correct encryption configuration, enabling automated remediation without manual intervention.
Variation 2. A company uses AWS Organizations to manage multiple accounts. The security team wants to continuously monitor the configurations of all AWS resources across the organization and receive alerts when a resource violates a compliance rule. For example, they want to ensure that all Amazon RDS databases are not publicly accessible, and that any new RDS instance created with public access enabled is automatically flagged. The team does not want to build custom scripts for monitoring. Which AWS service should the security team use to meet these requirements?
medium- A.AWS CloudTrail
- ✓ B.AWS Config
- C.AWS Trusted Advisor
- D.Amazon GuardDuty
Why B: AWS Config is the correct service because it provides continuous monitoring and recording of AWS resource configurations, and it can evaluate those configurations against custom or managed rules (e.g., 'rds-instance-public-access-check'). When a resource like an RDS instance violates a rule (e.g., being publicly accessible), AWS Config can automatically flag it and trigger an alert via Amazon SNS, all without requiring custom scripts.
