A service should be provided to arbitrary clients on the Internet using HTTPS. Any standard client on the Internet should be able to consume the service without further configuration. Which of the following approaches can be used to implement these requirements? (Choose three correct answers.)
To provide a service over HTTPS to arbitrary clients on the internet without further configuration, standard practices must be followed. Using a certificate issuing service to request certificates during each server deployment ensures that the certificates are trusted by clients (option C). A load balancer that decrypts incoming requests and passes them as plain HTTP to the backend servers simplifies SSL management and reduces the overhead on the backend servers (option D). Installing a wildcard certificate and the respective private key on all backend servers allows multiple subdomains to be handled securely without requiring separate certificates for each subdomain (option E). Using self-signed certificates or not using certificates at all would prevent clients from trusting the service and is therefore not suitable (options A and B).
i agree with hector1978 the correcte answer is CDE
Option B is not suitable. In this case it would be option E
IS BCD, e a wildcard certificate is for various subdomains, and it will be just one for all servers
