A: Yes: hile ordinary Amazon Route 53 resource record sets are standard DNS resource record sets, alias resource record sets provide an Amazon Route 53–specific extension to DNS functionality. Instead of an IP address or a domain name, an alias resource record set contains a pointer to a CloudFront distribution, an Elastic Beanstalk environment, an ELB Classic, Application, or Network Load Balancer, an Amazon S3 bucket that is configured as a static website, or another Amazon Route 53 resource record set in the same hosted zone. When Amazon Route 53 receives a DNS query that matches the name and type in an alias resource record set, Amazon Route 53 follows the pointer and responds with the applicable value:
C: Yes: A CNAME record can point to any DNS record hosted anywhere, including to the resource record set that Amazon Route 53 automatically creates when you create a policy record.
