SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 configuring Amazon GuardDuty for the first time. The engineer wants to receive alerts when GuardDuty generates a finding of severity HIGH or higher. What is the simplest way to achieve this?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create an Amazon EventBridge rule that matches GuardDuty findings and triggers an SNS topic.
Option B is correct because GuardDuty can send findings directly to CloudWatch Events (EventBridge), which can then invoke a Lambda function or send to an SNS topic. Option A is wrong because GuardDuty does not have native email alerts. Option C is wrong because GuardDuty does not use CloudWatch Logs directly. Option D is wrong because GuardDuty findings are not stored in S3 by default.
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.
✓
Create an Amazon EventBridge rule that matches GuardDuty findings and triggers an SNS topic.
Why this is correct
Simple and effective.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Configure CloudWatch Logs to monitor GuardDuty logs and create a metric filter for high-severity findings.
Why it's wrong here
GuardDuty does not send logs to CloudWatch Logs.
✗
Set up an S3 event notification on the GuardDuty findings bucket.
Why it's wrong here
Findings are not stored in S3 by default.
✗
Configure GuardDuty to send email notifications for all findings.
Why it's wrong here
No native email alerting.
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: Create an Amazon EventBridge rule that matches GuardDuty findings and triggers an SNS topic. — Option B is correct because GuardDuty can send findings directly to CloudWatch Events (EventBridge), which can then invoke a Lambda function or send to an SNS topic. Option A is wrong because GuardDuty does not have native email alerts. Option C is wrong because GuardDuty does not use CloudWatch Logs directly. Option D is wrong because GuardDuty findings are not stored in S3 by default.
What should I do if I get this SCS-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 SCS-C02 NAT questions on configuration and troubleshooting.
Are there clue words in this question I should notice?
Yes — watch for: "first". Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
