This SOA-C02 practice question tests your understanding of security and compliance. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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's security team notices that an IAM user has been generating multiple access keys and deleting them within a short period. The SysOps administrator needs to detect and alert on this behavior. Which solution is the MOST effective?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable AWS CloudTrail and create a CloudWatch Events rule that triggers on iam:CreateAccessKey events and sends a notification to an SNS topic.
Option B is correct because AWS CloudTrail logs all IAM API calls, and CloudWatch Events can trigger on the CreateAccessKey event. Option A is wrong because IAM Access Analyzer analyzes resource policies, not user activity. Option C is wrong because AWS Config evaluates resource compliance, not API call patterns. Option D is wrong because Trusted Advisor does not monitor user behavior.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Enable AWS Trusted Advisor security checks and review the report weekly.
Why it's wrong here
Trusted Advisor does not provide real-time alerts on user activity.
✗
Enable IAM Access Analyzer to analyze user activity and send alerts.
Why it's wrong here
IAM Access Analyzer reviews resource policies, not user actions.
✓
Enable AWS CloudTrail and create a CloudWatch Events rule that triggers on iam:CreateAccessKey events and sends a notification to an SNS topic.
Why this is correct
CloudTrail logs API calls and CloudWatch Events can respond in real time.
Related concept
Static NAT maps one inside address to one outside address.
✗
Use AWS Config to track IAM user configuration changes and trigger an alert when an access key is created.
Why it's wrong here
AWS Config records resource changes, not API calls.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SOA-C02 NAT questions on configuration and troubleshooting.
Security and Compliance — This question tests Security and Compliance — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: Enable AWS CloudTrail and create a CloudWatch Events rule that triggers on iam:CreateAccessKey events and sends a notification to an SNS topic. — Option B is correct because AWS CloudTrail logs all IAM API calls, and CloudWatch Events can trigger on the CreateAccessKey event. Option A is wrong because IAM Access Analyzer analyzes resource policies, not user activity. Option C is wrong because AWS Config evaluates resource compliance, not API call patterns. Option D is wrong because Trusted Advisor does not monitor user behavior.
What should I do if I get this SOA-C02 question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SOA-C02 NAT questions on configuration and troubleshooting.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
