This SCS-C02 practice question tests your understanding of infrastructure security. 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 Shield Advanced to protect its web application from DDoS attacks. The security team wants to receive real-time notifications when a DDoS attack is detected. Which configuration should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Amazon CloudWatch Events to trigger an AWS Lambda function that sends an Amazon SNS notification when a Shield Advanced event occurs.
Option B is correct because Shield Advanced sends events to CloudWatch Events, which can trigger a Lambda function to send notifications. Option A is wrong because CloudTrail does not capture DDoS events. Option C is wrong because VPC Flow Logs are for network traffic, not DDoS events. Option D is wrong because Shield Advanced does not directly integrate with SNS; it uses CloudWatch Events.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Use Amazon CloudWatch Events to trigger an AWS Lambda function that sends an Amazon SNS notification when a Shield Advanced event occurs.
Why this is correct
Shield Advanced publishes events to CloudWatch Events.

✗
Enable VPC Flow Logs and create a CloudWatch alarm for high traffic volume.
Why it's wrong here
Flow Logs are for traffic logs, not DDoS detection events.
✗
Subscribe an SNS topic to Shield Advanced notifications directly.
Why it's wrong here
Shield Advanced does not directly send to SNS; it uses CloudWatch Events.
✗
Enable AWS CloudTrail and create a metric filter for DDoS events.
Why it's wrong here
CloudTrail does not log DDoS events.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
