A start-up firm has configured an Amazon S3 bucket as a static website with a DNS registered name as test.com. For an appropriate record to be created in Amazon Route 53, the deployment team is seeking your advice. Also, they are looking for TTL values that can be set for these records.
Which of the following can be used for the creation of records within Amazon Route 53?

Answer options:

A.Create an Alias record for the domain name test.com with custom TTL values.
B.Create CNAME records for the domain name test.com with default TTL values.
C.Create CNAME records for the domain name test.com with custom TTL values.
D.Create an Alias record for the domain name test.com with default TTL values.

Correct Answer: D
Alias records can be used to map a DNS record test.com to the Amazon S3 bucket static website. With Alias records, custom TTL values cannot be set. Only default TTL values are used.
Option A is incorrect as with Alias record, a custom TTL value cannot be set. Route 53 uses default TTL values for the resource.
Options B and C are incorrect as CNAME record cannot be used for apex records, i.e., for test.com
