}Based on the exhibit, the security team wants centralized detection and alerting for both successful and failed attempts to change S3 bucket policies and KMS key policies across multiple accounts. Which approach best meets the requirement?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Enable S3 server access logging on each bucket and archive the logs in the security account.
Server access logs do not capture KMS key policy changes or rich API management events.
B
Distractor review
Use AWS Config rules only, because Config records every successful and failed API call automatically.
AWS Config tracks configuration state, but it is not the primary mechanism for failed API attempt alerting across all services.
C
Best answer
Create an organization CloudTrail trail for management events and add EventBridge rules in the security account to alert on PutBucketPolicy and PutKeyPolicy events, including failed calls.
An organization trail captures the API activity across accounts, and EventBridge can route both successful and failed management events to alerts centrally.
D
Distractor review
Enable GuardDuty in every account and use its findings as the main source for policy change notifications.
GuardDuty is valuable for threat detection, but it is not a direct, comprehensive audit trail for policy change API calls.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Create an organization CloudTrail trail for management events and add EventBridge rules in the security account to alert on PutBucketPolicy and PutKeyPolicy events, including failed calls. — The requirement is centralized visibility into policy changes across the organization, including failed attempts. CloudTrail management events are the source of truth for API activity such as PutBucketPolicy and PutKeyPolicy. An organization trail ensures all member accounts are captured in one place, and EventBridge can match those events and send notifications to SNS, Lambda, or another alerting target. This combines durable audit logging with real-time detection. S3 server access logs are for object access, not policy-change management events. AWS Config is useful for configuration drift, but it is not the best direct alerting path for failed API calls across both S3 and KMS. GuardDuty is a detection service, but it does not replace CloudTrail for explicit auditability of policy changes and denied attempts.
