* C. Using a certificate issuing service (e.g., Let's Encrypt) allows each server to obtain a valid, trusted certificate, ensuring secure HTTPS communication. * D. A load balancer can handle HTTPS termination, decrypting incoming HTTPS requests and forwarding them as plain HTTP to backend servers. * E. Installing a wildcard certificate on all backend servers ensures that each server can handle HTTPS requests using the same certificate, simplifying management.
