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) act at the subnet level, controlling traffic to/from subnets.
Security groups act as an instance-level firewall, controlling inbound and outbound access at the instance level.
AWS Trusted Advisor provides recommendations for AWS resources but does not control network access.
Virtual private gateways connect on-premises networks to AWS VPCs but do not control instance-level access.
I infer that the answer is:
Security groups
I compute that the answer is:
Security groups
