Answer: Security groups in conjunction with route tables
The correct answer is B. Security groups act as virtual firewalls for EC2 instances, controlling inbound and outbound traffic. Route tables, on the other hand, determine the path for traffic to and from subnets within a VPC or to a virtual private gateway for accessing external resources. Option A is incorrect because web application firewalls are not a service provided by AWS for routing traffic at the network level. Option C is incorrect because a network intrusion system is not a standard AWS service for routing traffic in a VPC. Option D is incorrect because AWS Shield is a service for protecting against DDoS attacks, not for routing traffic.
