AWS Certified Cloud Practitioner — Question 760

A company wants to use an Amazon EC2 instance that has a pre-installed third-party firewall.

Which AWS service or feature can provide this solution?

Answer options

• A. Security groups
• B. AWS Marketplace
• C. AWS Systems Manager
• D. AWS Certificate Manager (ACM)

Correct answer: B

Explanation

AWS Marketplace offers a digital catalog where customers can find, buy, and deploy third-party software, including pre-configured Amazon Machine Images (AMIs) containing firewalls. Security groups only provide basic stateful filtering at the instance level and do not host third-party software. AWS Systems Manager is used for operational management, and AWS Certificate Manager manages SSL/TLS certificates, neither of which provides pre-installed software images.
