- A
AWS Config
AWS Config provides continuous monitoring and evaluation of resource configurations against desired policies. It supports multi-account aggregation via AWS Organizations, allowing you to apply rules centrally and view compliance across all accounts.
- B
AWS Trusted Advisor
Why wrong: AWS Trusted Advisor offers best-practice checks, including S3 bucket permissions, but it does not allow you to define custom rules or aggregate compliance results across multiple accounts in a single dashboard. It provides recommendations, not continuous enforcement or custom policy evaluation.
- C
Amazon Inspector
Why wrong: Amazon Inspector is designed for vulnerability assessments and network security analysis of Amazon EC2 instances and container images. It does not evaluate S3 bucket policies or provide multi-account compliance aggregation for resource configurations.
- D
AWS Shield
Why wrong: AWS Shield is a managed DDoS protection service. It does not evaluate resource configurations or enforce security policies like S3 bucket access controls.
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 within AWS Organizations. The security team needs to automatically check that no Amazon S3 bucket in any account has public read or write access. They want to define a security rule once and have it evaluated continuously across all accounts. The team also needs to view the overall compliance status from a single dashboard. Which AWS service should they use to meet these requirements?
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 Config
AWS Config is the correct service because it provides managed rules (such as 's3-bucket-public-read-prohibited' and 's3-bucket-public-write-prohibited') that can be defined once in a delegated administrator account and automatically evaluated across all member accounts in AWS Organizations. It continuously monitors S3 bucket configurations and aggregates compliance results into a single dashboard (the AWS Config aggregator), meeting the requirement for a unified view of overall compliance status.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
AWS Trusted Advisor
Why it's wrong here
AWS Trusted Advisor offers best-practice checks, including S3 bucket permissions, but it does not allow you to define custom rules or aggregate compliance results across multiple accounts in a single dashboard. It provides recommendations, not continuous enforcement or custom policy evaluation.
When this WOULD be correct
A company wants a quick, no-configuration overview of their AWS account's adherence to AWS best practices, including S3 bucket public access checks, and they only need a summary report without custom rules or cross-account aggregation.
- ✗
Amazon Inspector
Why it's wrong here
Amazon Inspector is designed for vulnerability assessments and network security analysis of Amazon EC2 instances and container images. It does not evaluate S3 bucket policies or provide multi-account compliance aggregation for resource configurations.
When this WOULD be correct
An exam question where the requirement is to automatically assess EC2 instances for software vulnerabilities, unintended network exposure, or deviations from security best practices, and you need to view findings in a single dashboard.
- ✗
AWS Shield
Why it's wrong here
AWS Shield is a managed DDoS protection service. It does not evaluate resource configurations or enforce security policies like S3 bucket access controls.
When this WOULD be correct
A company wants to protect its web applications from DDoS attacks and needs a managed service that provides always-on detection and automatic mitigations. AWS Shield would be the correct answer in that scenario.
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 Trusted AdvisorWrong answer — click to see why▾
Why this is wrong here
AWS Trusted Advisor provides best-practice checks, including S3 bucket permissions, but it does not allow you to define custom rules or evaluate compliance continuously across all accounts from a single dashboard. It also does not integrate with AWS Organizations to aggregate compliance status.
★ When this WOULD be the correct answer
A company wants a quick, no-configuration overview of their AWS account's adherence to AWS best practices, including S3 bucket public access checks, and they only need a summary report without custom rules or cross-account aggregation.
Why candidates choose this
Candidates may confuse Trusted Advisor's security checks (like S3 bucket permissions) with the ability to define and enforce custom rules, and they might overlook the requirement for custom rules and cross-account dashboard aggregation.
✗Amazon InspectorWrong answer — click to see why▾
Why this is wrong here
Amazon Inspector is designed for vulnerability management and network security assessments of EC2 instances and container workloads, not for evaluating S3 bucket policies or compliance across multiple accounts.
★ When this WOULD be the correct answer
An exam question where the requirement is to automatically assess EC2 instances for software vulnerabilities, unintended network exposure, or deviations from security best practices, and you need to view findings in a single dashboard.
Why candidates choose this
Candidates may confuse Inspector's security assessment capabilities with the broader compliance evaluation needed for S3 bucket policies, or assume it can check all AWS resources.
✗AWS ShieldWrong answer — click to see why▾
Why this is wrong here
AWS Shield is a managed DDoS protection service, not a configuration compliance or auditing tool. It does not check S3 bucket policies for public access or provide a compliance dashboard across multiple accounts.
★ When this WOULD be the correct answer
A company wants to protect its web applications from DDoS attacks and needs a managed service that provides always-on detection and automatic mitigations. AWS Shield would be the correct answer in that scenario.
Why candidates choose this
Candidates may confuse AWS Shield with a security service that monitors all types of security threats, including misconfigurations, due to its name implying broad protection.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse AWS Config (which evaluates resource configurations against rules) with AWS Trusted Advisor (which provides best-practice checks but lacks custom rule definition and multi-account aggregation), leading them to select Trusted Advisor because it also checks S3 bucket permissions.
Detailed technical explanation
How to think about this question
Under the hood, AWS Config uses a configuration recorder to capture resource configuration changes and evaluates them against AWS Config managed rules or custom Lambda-based rules. For multi-account scenarios, you enable AWS Config in each account and use an aggregator in a central account to collect compliance snapshots from all accounts, which allows you to view overall compliance status without needing to log into each account individually. A subtle behavior is that AWS Config rules are evaluated only when a configuration change occurs or during periodic evaluations (if configured), so near-real-time detection depends on the evaluation trigger frequency.
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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
