Selected Answer: B

You really do not need the firewall manager. It makes no mention of multiple accounts, hence waf with reputation is good enough.

my answer is C. I think WAF is good combination with CloudFront but WAF is best at blocking massive attacks like DDoS. Question is about blocking fraudulent postings, so AWS Firewall Manager can be proper choice over WAF.

B The Amazon IP reputation list rule group contains rules that are based on Amazon internal threat intelligence. This is useful if you would like to block IP addresses typically associated with bots or other threats. Inspects for a list of IP addresses that have been identified as bots by Amazon threat intelligence.
