Which AWS networking primitive is STATEFUL, lives at the ENI level, allows traffic by allow-rules-only (implicit deny), and is the primary access control for EC2 / RDS / Lambda-in-VPC?
AAmazon Route 53
BSecurity Groups
CAWS Snowball
DNetwork ACLs
Answer & Solution
Correct answer: B. Security Groups
Security Groups are stateful, ENI-attached, allow-only (per SCS-C02 §3.2). NACLs are subnet-level + stateless; Route 53/Snowball are unrelated.
