Answer: Configure TCP Proxy Load Balancing as a global load balancing service listening on port 995.
The correct answer is A because TCP Proxy Load Balancing is a global load balancing service that operates at Layer 4 (TCP/SSL) and supports routing traffic to the nearest backend based on client geographic location when using Premium Tier. This makes it ideal for non-HTTP protocols like mail services (port 995 for POP3S). The community discussion strongly supports A with high upvotes (e.g., 27 upvotes for ESP_SAP's comment citing official documentation) and detailed reasoning that TCP Proxy Load Balancing is global and automatically directs traffic to the closest region with capacity. Option B (Network Load Balancer) is incorrect because it is regional and cannot route traffic across multiple regions globally. Option C (HTTP(S) Load Balancer) is unsuitable as it only handles HTTP/HTTPS traffic, not TCP-based mail protocols. Option D (Cloud CDN) is inappropriate as it is designed for HTTP content caching and cannot route real-time mail traffic.
