Security Groups — AWS Cloud Practitioner (CLF-C02) Practice Questions
Security groups are stateful virtual firewalls that control inbound and outbound traffic at the EC2 instance level within a VPC. Because they are stateful, a response to an allowed inbound request is automatically permitted outbound without an explicit rule. The CLF-C02 exam expects you to understand that security groups operate as an allow-only mechanism, meaning traffic is blocked by default unless a rule explicitly permits it. They are a foundational layer of network security for any AWS workload.
