Which of the following acts as an instance-level firewall to control inbound and outbound access?
Network access control list
Security groups
AWS Trusted Advisor
Virtual private gateways
Explanations:
Network access control lists (NACLs) work at the subnet level, controlling traffic to and from an entire subnet.
Security groups act as instance-level firewalls, controlling inbound and outbound access for individual instances.
AWS Trusted Advisor is a management tool that provides best-practice recommendations but does not control traffic.
Virtual private gateways enable private connectivity to AWS but do not act as firewalls for instance-level traffic.
I draft that the answer is:
Security groups
As I understand it, the answer is:
Security groups
