AWS Certified Cloud Practitioner (CLF-C02) — Question 397

Which AWS service or resource can a company use to deploy AWS WAF rules?

Answer options

• A. Amazon EC2
• B. Application Load Balancer
• C. AWS Trusted Advisor
• D. Network Load Balancer

Correct answer: B

Explanation

AWS WAF can be directly associated with an Application Load Balancer (ALB) to protect web applications from common web exploits. It cannot be deployed directly on Amazon EC2 instances or Network Load Balancers (NLB), which do not support direct AWS WAF integration. AWS Trusted Advisor is an optimization tool that provides recommendations rather than serving as a deployment target for security rules.
