Question

Quizplus · Accepted Answer

The correct answer is A because it uses AWS WAF to block requests that do not originate from the specified country. AWS WAF is a web application firewall that can be used to protect web applications from a variety of threats, including IP-based attacks. The solution also requires the least possible maintenance because AWS WAF is a managed service that is automatically updated and patched by AWS.
