Multiple-Response Questions: Select multiple correct answers (typically 2-3 correct from 5-6 options).
Security questions often involve scenario-based decision-making about the best security approach given constraints.
Common Exam Scenarios
SCS-C02 scenarios often include:
- Access control: “Design IAM policy for cross-account access while maintaining least privilege”
- Data protection: “Encrypt data at rest and in transit while meeting compliance requirements”
- Threat response: “Investigate unusual CloudTrail activity and implement automated remediation”
- Network security: “Design network architecture that restricts traffic and prevents lateral movement”
- Compliance: “Implement controls to meet PCI-DSS requirements in AWS”
Real-world security challenges requiring thoughtful solutions are typical.
