Your company is planning to use Route 53 as the DNS provider. There is a need to ensure that the company`s domain name points to an existing CloudFront distribution. How could this be achieved?

Answer options:

A.Create an Alias record which points to the CloudFront distribution.
B.Create a host record which points to the CloudFront distribution.
C.Create a CNAME record which points to the CloudFront distribution.
D.Create a Non-Alias Record which points to the CloudFront distribution.

Correct Answer - A
AWS Documentation mentions the following.
While ordinary Amazon Route 53 records are standard DNS records, alias records provide a Route 53–specific extension to the DNS functionality. Instead of an IP address or a domain name, an alias record 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 Route 53 record in the same hosted zone. When Route 53 receives a DNS query that matches the name and type in an alias record, Route 53 follows the pointer and responds with the applicable value.

Note: 
Route 53 uses "Alias Name" to connect to the CloudFront as Alias Record is a Route 53 extension to DNS.Also, an Alias record is similar to a CNAME record, but the main difference is - you can create an Alias record for both root domain & subdomain. In contrast, a CNAME record can be created only to subdomain. Check the below link to get more information:
