  Correct answer: A. Configure TCP Proxy Load Balancing as a global load balancing service listening on port 995. Brief explanation: Mail protocols (e.g., POP3S — port 995) require a load balancer operating at the TCP level with global routing. TCP Proxy Load Balancing is a global service that can route TCP traffic (including port 995) to the nearest (geographically/latency) backend. Network Load Balancer (B) is regional, not global. HTTP(S) Load Balancer (C) — works only with HTTP/HTTPS, not suitable for mail protocols. Cloud CDN (D) — for HTTP(S) caching, not for TCP/mail.
