All about WAF for AWS Exam and later

Web Application Firewall ( WAF) in General WAF filters, monitors, and blocks HTTP traffic to and from a web application.

Prepare your own notes. Trust me, it helps! You can compare it later with others to fill gaps if any. This is in many a sense going beyond the exam preparation and helps facing the real world situations like job-interviews, solution-consulting, problem-solving at work. Ask how? Because it helps you internalize the concepts. Practice more and more mock tests. Don't skip it, ever. It pays to tone your mind for the exam nitty-gritties.
