- A
Amazon Inspector
Why wrong: Amazon Inspector assesses EC2 instances for software vulnerabilities and network exposure, not S3 bucket configurations.
- B
AWS Config
AWS Config has managed rules to evaluate resource settings, including S3 bucket encryption. It can automatically detect non-compliant buckets and send notifications.
- C
AWS CloudTrail
Why wrong: CloudTrail logs API activity but does not perform proactive compliance checks on resource configurations.
- D
Amazon GuardDuty
Why wrong: GuardDuty is a threat detection service that monitors for malicious activity; it does not evaluate encryption settings.
Question 437 of 1,546
SOA-C02 Security and Compliance Practice Question
This SOA-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. A key principle to apply: aWS Config continuously monitors and records AWS resource configurations.. 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's security policy requires that all Amazon S3 buckets must have server-side encryption enabled. The SysOps administrator needs to automatically detect any bucket that does not have encryption enabled and notify the security team. Which AWS service should be used to detect non-compliant buckets?
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 continuously monitors and evaluates the configuration of AWS resources against desired policies. By using an AWS Config managed rule such as `s3-bucket-server-side-encryption-enabled`, you can automatically detect any S3 bucket that lacks server-side encryption and trigger an SNS notification to the security team.
Key principle: AWS Config continuously monitors and records AWS resource configurations.

AWS Config
Why this is correct
AWS Config has managed rules to evaluate resource settings, including S3 bucket encryption. It can automatically detect non-compliant buckets and send notifications.
Related concept

AWS CloudTrail
Why it's wrong here
CloudTrail logs API activity but does not perform proactive compliance checks on resource configurations.
- ✗
Amazon GuardDuty
Why it's wrong here
GuardDuty is a threat detection service that monitors for malicious activity; it does not evaluate encryption settings.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing AWS Config's configuration compliance monitoring with AWS CloudTrail's API logging or GuardDuty's threat detection, leading candidates to choose a service that records actions rather than one that evaluates resource states.
Detailed technical explanation
How to think about this question
AWS Config evaluates resource configurations using managed or custom rules written in AWS Lambda. The `s3-bucket-server-side-encryption-enabled` rule checks the `x-amz-server-side-encryption` header on the bucket's default encryption configuration; if the bucket does not have SSE-S3, SSE-KMS, or DSSE-KMS enabled, the rule marks it as non-compliant. In a real-world scenario, you can combine this rule with an AWS Config remediation action to automatically apply encryption or send a notification via Amazon SNS to the security team.
KKey Concepts to Remember
- AWS Config continuously monitors and records AWS resource configurations.
- AWS Config uses managed rules to evaluate resource compliance against policies.
- The `s3-bucket-server-side-encryption-enabled` rule checks S3 bucket encryption.
- AWS Config can integrate with SNS to send notifications for non-compliant resources.
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 Config continuously monitors and records AWS resource configurations.
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 |
