You have a collection of assets stored in an S3 bucket. You want to enable users across the world to access these assets with the least latency. The users must also access the distribution via your company domain name. How can you achieve this? Choose 2 answers from the options given below.

Answer options:

A.Create a web based distribution in Cloudfront.
B.Create an application load balancer and point it to your S3 bucket.
C.Create a resource record in a hosted zone and create an ALIAS record.
D.Create a resource record in a hosted zone and create a PTR record.

Answer – A and C
This is also given in the AWS Documentation.
Routing Traffic to an Amazon CloudFront Web Distribution by Using Your Domain Name
If you want to speed up the delivery of your web content, you can use Amazon CloudFront, the AWS content delivery network (CDN). CloudFront can deliver your entire website—including dynamic, static, streaming, and interactive content—by using a global network of edge locations. Requests for your content are automatically routed to the edge location that gives your users the lowest latency.
 Note 
 You can route traffic to a CloudFront distribution only for public hosted zones.
To use CloudFront to distribute your content, you create a web distribution and specify settings such as the Amazon S3 bucket or HTTP server that you want CloudFront to get your content from, whether you want only selected users to have access to your content, and whether you want to require users to use HTTPS.
When you create a web distribution, CloudFront assigns a domain name to the distribution, such as d111111abcdef8.cloudfront.net. You can use this domain name in the URLs for your content, for example:
http://d111111abcdef8.cloudfront.net/logo.jpg
Alternatively, you might prefer to use your own domain name in URLs, for example:
http://example.com/logo.jpg
If you want to use your own domain name, use Amazon Route 53 to create an alias record that points to your CloudFront distribution. An alias record is a Route 53 extension to DNS. It`s similar to a CNAME record, but you can create an alias record both for the root domain, such as example.com, and for subdomains, such as www.example.com. (You can create CNAME records only for subdomains.) When Route 53 receives a DNS query that matches the name and type of an alias record, Route 53 responds with the domain name that is associated with your distribution.
Option B is incorrect since you can’t use S3 behind the Application Load balancer.
Option D is incorrect because you need to define an ALIAS record.
