The answer is to use AWS CloudTrail to log API calls and Amazon CloudWatch Events to send alerts. This combination works because CloudTrail records every IAM policy change as a management event, capturing the who, what, and when of the API call, while CloudWatch Events can filter for those specific events and trigger an SNS notification or Lambda function for immediate alerting. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your understanding of the distinct roles of monitoring services: CloudTrail for auditing API activity, CloudWatch Events for real-time event-driven responses, and AWS Config for configuration history rather than live alerts. A common trap is confusing CloudTrail with CloudWatch Logs—remember that CloudWatch Logs stores log data but does not natively capture API calls, and GuardDuty is for threat detection, not policy change logging. Memory tip: think "Trail tracks the action, Events alerts the reaction."
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's compliance team requires that all changes to IAM policies be logged and immediately alerted. Which AWS solution should be used?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS CloudTrail to log API calls and Amazon CloudWatch Events to send alerts.
Option A is correct because CloudTrail logs IAM policy changes, and CloudWatch Events can trigger alerts. Option B is wrong because AWS Config records configuration changes but does not provide real-time alerting. Option C is wrong because CloudWatch Logs does not capture API calls. Option D is wrong because GuardDuty is for threat detection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use AWS Config rules to monitor IAM policy changes and send notifications.
Why it's wrong here
Config evaluates rules periodically, not in real time.
✗
Use Amazon CloudWatch Logs to capture IAM policy changes and create metric filters.
Why it's wrong here
CloudWatch Logs does not capture IAM policy changes directly.
✗
Use Amazon GuardDuty to detect unauthorized IAM policy changes.
Why it's wrong here
GuardDuty does not monitor IAM policy changes.
✓
Use AWS CloudTrail to log API calls and Amazon CloudWatch Events to send alerts.
Why this is correct
CloudTrail logs the changes, and CloudWatch Events can trigger alerts in real time.

TExam Day Tips
→Underline the problem statement mentally.
→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 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.
