SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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 security engineer is responsible for monitoring AWS account activity. The engineer needs to receive real-time notifications when specific API calls are made, such as 'DeleteTrail' or 'UpdateTrail'. The engineer wants to use AWS services to achieve this with minimal latency. Which combination of services should the engineer use?
Why wrong: EventBridge can be used, but CloudTrail does not automatically send events to EventBridge; a rule must be set up and it may have slight delay.
CloudTrail delivers events to CloudWatch Logs in near real-time. You can then create a CloudWatch Logs metric filter to match specific API calls and set up a CloudWatch alarm that triggers an SNS notification. This provides real-time alerts. Option A is correct. Option B is wrong because EventBridge can directly receive CloudTrail events, but CloudTrail logs are not automatically sent to EventBridge; you need to set up a rule. Option C is wrong because CloudWatch Logs subscription filters are for streaming to other services, not for real-time alarms. Option D is wrong because S3 event notifications are not real-time and are for object-level events.
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.
✗
CloudTrail -> Amazon EventBridge -> Amazon SNS
Why it's wrong here
EventBridge can be used, but CloudTrail does not automatically send events to EventBridge; a rule must be set up and it may have slight delay.
This architecture provides near real-time alerting based on API calls.
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.
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 SCS-C02 NAT questions on configuration and troubleshooting.
Security Logging and Monitoring — This question tests Security Logging and Monitoring — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: CloudTrail -> CloudWatch Logs -> CloudWatch metric filter -> CloudWatch alarm -> Amazon SNS — CloudTrail delivers events to CloudWatch Logs in near real-time. You can then create a CloudWatch Logs metric filter to match specific API calls and set up a CloudWatch alarm that triggers an SNS notification. This provides real-time alerts. Option A is correct. Option B is wrong because EventBridge can directly receive CloudTrail events, but CloudTrail logs are not automatically sent to EventBridge; you need to set up a rule. Option C is wrong because CloudWatch Logs subscription filters are for streaming to other services, not for real-time alarms. Option D is wrong because S3 event notifications are not real-time and are for object-level events.
