- A
Use AWS Config with the 's3-bucket-public-read-prohibited' managed rule and configure automatic remediation to block public access.
AWS Config continuously evaluates bucket configurations and can automatically remediate noncompliant buckets using pre-built automation.
- B
Create an Amazon EventBridge (CloudWatch Events) rule that triggers an AWS Lambda function to check and fix public read access.
Why wrong: While this works, it requires custom Lambda code, which is more effort than using AWS Config's managed rule with remediation.
- C
Apply an S3 bucket policy to each bucket that denies public read access.
Why wrong: This requires manual per-bucket configuration and does not automatically detect new buckets or changes.
- D
Use AWS Trusted Advisor to check for public read access and manually remediate when notified.
Why wrong: Trusted Advisor provides checks but requires manual remediation; it does not automatically fix the issue within five minutes.
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. 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 Amazon S3 to store sensitive customer data. A SysOps administrator needs to ensure that any S3 bucket that is incorrectly configured to allow public read access is automatically remediated within five minutes. The administrator wants to use native AWS services with minimal custom code. Which solution should be used?
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
Use AWS Config with the 's3-bucket-public-read-prohibited' managed rule and configure automatic remediation to block public access.
AWS Config with the 's3-bucket-public-read-prohibited' managed rule can automatically evaluate S3 bucket configurations against the desired state. When a non-compliant bucket is detected, AWS Config can trigger an automatic remediation action (e.g., applying an S3 bucket policy or blocking public access) using AWS Systems Manager Automation documents, all within the required five-minute window and with minimal custom code.
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 often choose EventBridge + Lambda (Option B) because it seems more flexible, but they overlook the 'minimal custom code' constraint and the fact that AWS Config's managed rule with automatic remediation is a fully native, code-free solution.
Detailed technical explanation
How to think about this question
AWS Config's automatic remediation uses SSM Automation documents (e.g., AWS-DisableS3BucketPublicReadWrite) to execute remediation actions. The evaluation frequency can be set to as low as one minute, ensuring detection within the five-minute window. Under the hood, AWS Config evaluates resource configurations against the rule's logical condition (checking the bucket's public access block settings or bucket policy), and upon non-compliance, it invokes the remediation action via an SSM Automation runbook, which can apply an S3 bucket policy that denies public read access or enable S3 Block Public Access settings.
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.
