- A
AWS CloudTrail to deliver logs to a centralized S3 bucket with default encryption; AWS Config to monitor API activity; S3 server access logs enabled.
Why wrong: Config tracks resource configuration, not API activity.
- B
AWS CloudTrail to deliver logs to a centralized S3 bucket with default encryption; Amazon Macie to detect anomalous API activity; S3 server access logs enabled.
Why wrong: Macie detects sensitive data, not anomalous API activity.
- C
AWS CloudTrail to deliver logs to a centralized S3 bucket with default encryption; Amazon Detective to analyze API activity; S3 server access logs enabled.
Why wrong: Detective analyzes security data but does not provide ML-based anomaly detection for API activity across accounts as comprehensively as GuardDuty.
- D
AWS CloudTrail to deliver logs to a centralized S3 bucket with default encryption and S3 server access logs; Amazon GuardDuty enabled in all accounts.
CloudTrail logs to S3, GuardDuty provides ML-based anomaly detection across accounts, and S3 server access logs provide request logging.
Quick Answer
The answer is to use AWS CloudTrail delivering logs to a centralized S3 bucket with default encryption and S3 server access logs, combined with Amazon GuardDuty enabled in all accounts. This works because CloudTrail provides a centralized audit trail of API calls across all accounts in AWS Organizations, while GuardDuty uses machine learning and anomaly detection to identify unusual API activity, such as credential misuse or reconnaissance, across those accounts. On the AWS Certified Security Specialty SCS-C02 exam, this question tests your ability to distinguish between security services that use ML for different purposes—GuardDuty for threat detection versus Macie for sensitive data discovery. A common trap is choosing Amazon Detective, which analyzes post-breach findings but does not provide proactive ML-based anomaly detection for API activity like GuardDuty does. Memory tip: GuardDuty guards the door against suspicious API calls, while Macie minds the data inside the bucket.
SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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 AWS Organizations with multiple accounts. The security team wants to centrally monitor and analyze all CloudTrail logs from all accounts. The logs must be stored in a centralized S3 bucket with encryption and access logging enabled. Additionally, the team needs to detect anomalous API activity across accounts using machine learning. Which combination of services meets 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 CloudTrail to deliver logs to a centralized S3 bucket with default encryption and S3 server access logs; Amazon GuardDuty enabled in all accounts.
Option B is correct because Amazon Macie uses ML to discover sensitive data in S3, not to detect anomalous API activity. Option A is correct: CloudTrail delivers logs to a centralized S3 bucket, Amazon GuardDuty uses ML to detect anomalous API activity across accounts, and S3 server access logs record requests to the bucket. Option C is wrong because AWS Config tracks resource configuration changes, not API activity. Option D is wrong because Amazon Detective analyzes security data but does not provide ML-based anomaly detection for API activity like GuardDuty.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
