Question

Which type of recordset is generally used to point at AWS resources?

Option 1: TXT
Option 2: A
Option 3: AAAA
Option 4: A+Alias

Answer 1

An A+Alias record is commonly used in AWS Route 53 to link a domain to AWS resources, where Alias is an AWS-specific record type that maps domain names to AWS resources dynamically without using IP addresses.

Step-by-step explanation:

The type of recordset generally used to point at AWS resources is Option 4: A+Alias. When managing DNS records in AWS Route 53, an 'A' record is typically used to point a domain to an IPv4 address, while an 'AAAA' record points to an IPv6 address. A TXT record is used for providing text information to sources outside your domain. However, AWS Route 53 has a unique type of record called Alias, which allows you to point your domain to AWS resources such as Elastic Load Balancers, CloudFront distributions, or S3 buckets without needing an IP address. This Alias record type is specific to AWS and can be used like an 'A' record but with the benefit of dynamically resolving AWS resource endpoints.
