3. C. Use Route 53 for domain registration. Register 2048-bit encryption keys from a third-party certificate service. Use a third-party DNS service that supports DNSSEC for DNS requests that use the customer managed keys. Import the customer managed keys to ACM to deploy the certificates to Classic Load Balancers configured with those TLS/SSL certificates for the site. Use the Server Name Identification extension in all clients requests to the site.
4. D. Use Route 53 for domain registration, and host the company DNS root servers on Amazon EC2 instances running Bind. Enable DNSSEC for DNS requests. Use ACM to register TLS/SSL certificates for the shopping website, and use Application Load Balancers configured with those TLS/SSL certificates for the site.
