Which AWS service or feature gives a company the ability to control incoming traffic and outgoing traffic for Amazon EC2 instances?
Security groups
Amazon Route 53
AWS Direct Connect
Amazon VPC
Explanations:
Security groups act as virtual firewalls for EC2 instances, controlling both inbound and outbound traffic.
Amazon Route 53 is a DNS web service that routes end users to applications but does not control EC2 traffic.
AWS Direct Connect is a dedicated network connection for secure, high-bandwidth data transfer but does not manage EC2 traffic.
Amazon VPC provides a private network for EC2 instances, but traffic control is handled by security groups within the VPC.
I believe the answer is:
Security groups
As far as I can tell, the answer is:
