Answer: B AWS WAF supports geo-matching rules, allowing you to easily block requests based on country of origin. This eliminates the need to manually manage IP ranges. Option C - Shield primarily defends against DDoS attacks and does not offer granular geo-blocking capabilities.

Why not A? Option A allows for logging of blocked requests while minimizing maintenance needs, as AWS WAF handles updates to IP ranges effectively.
