The answer is to create an EventBridge rule that matches the CreateAccessKey API call and triggers an SNS notification. This is correct because CloudTrail logs all management events, and EventBridge (formerly CloudWatch Events) can filter these logs in real time for specific API actions like CreateAccessKey, then immediately invoke a target such as an SNS topic—no polling or additional log analysis is needed. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your understanding of event-driven monitoring versus batch-based solutions; a common trap is choosing a solution that uses CloudWatch Logs Insights or Athena, which require querying stored logs after the fact and introduce latency. The key concept is that EventBridge provides real-time, stateless event matching directly from CloudTrail streams, making it the most efficient for immediate notification. Memory tip: think “EventBridge catches the API call as it happens—no waiting, no querying.”
SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. 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 CloudTrail to log all management events. The SysOps administrator needs to be notified when an IAM user creates a new access key. Which configuration is the MOST efficient?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a CloudWatch Events rule that matches the CreateAccessKey API call and triggers an SNS notification.
Option C is correct because CloudWatch Events (now Amazon EventBridge) can directly match the CreateAccessKey API call from CloudTrail in real time and trigger an SNS notification. This is the most efficient solution as it requires no additional log analysis or polling, and it reacts immediately when the API call occurs.
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.
✗
Create a CloudWatch Logs metric filter on the CloudTrail log group for CreateAccessKey events and set an alarm.
Why it's wrong here
This works but is less efficient than using CloudWatch Events directly.
✗
Use AWS Trusted Advisor to check for excessive access keys.
Why it's wrong here
Trusted Advisor provides best-practice checks, not real-time API monitoring.
✓
Create a CloudWatch Events rule that matches the CreateAccessKey API call and triggers an SNS notification.
Why this is correct
CloudWatch Events can directly react to CloudTrail API calls and send notifications.

✗
Use AWS Config to monitor the 'iam-user' resource type for changes to access keys.
Why it's wrong here
AWS Config evaluates resource configuration, not API calls.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often default to CloudWatch Logs metric filters (Option A) because they are familiar with log-based monitoring, but they overlook the more efficient and real-time event-driven approach using CloudWatch Events/EventBridge for API call notifications.
Detailed technical explanation
How to think about this question
CloudWatch Events (EventBridge) uses event patterns to match specific API calls recorded by CloudTrail, such as 'CreateAccessKey', and can invoke targets like SNS, Lambda, or SQS within seconds of the API call. This event-driven architecture avoids the overhead of polling or log parsing, making it ideal for real-time operational alerts. Under the hood, EventBridge evaluates events against rules as they are emitted, ensuring near-instantaneous response without the need for metric aggregation.

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 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.
