A company needs to run a pre-installed third-party firewall on an Amazon EC2 instance.
Which AWS service or feature can provide this solution?
Network ACLs
Security groups
AWS Marketplace
AWS Trusted Advisor
Explanations:
Network ACLs provide a stateless layer of security at the subnet level, not suitable for running software like firewalls.
Security groups act as virtual firewalls for controlling inbound and outbound traffic at the instance level, but they are not third-party firewalls.
AWS Marketplace offers third-party software, including pre-installed firewalls, which can be deployed on Amazon EC2 instances.
AWS Trusted Advisor provides recommendations to improve AWS environments but does not provide firewall software.
I rank that the answer is:
