Configure White Label Name Servers in AWS

Answer - D.

This is given in the AWS documentation.

Each Amazon Route 53 hosted zone is associated with four name servers, known collectively as a delegation set.

By default, the name servers have names like ns-2048.awsdns-64.com.

If you want the domain name of your name servers to be the same as the domain name of your hosted zone, for example, ns1.example.com, you can configure white label name servers, also known as vanity name servers or private name servers.

The correct answer is D. This is when you want to have name servers in Route53 to be the same as the domain name of your hosted zone.

Explanation: When you create a hosted zone in Amazon Route 53, you are provided with a set of default name servers that you can use to manage your DNS resolution. However, if you want to use your own custom domain name as the name server for your hosted zone, you can configure white label name servers in AWS.

White label name servers allow you to use your own domain name as the name servers for your hosted zone. This means that instead of using the default name servers provided by Route 53, you can use your own custom domain name as the authoritative name servers for your domain.

To configure white label name servers in AWS, you will need to create a delegation set in Route 53. A delegation set is a set of four name servers that are associated with your custom domain name. You can then use these name servers to delegate DNS resolution for your domain to Route 53.

Once you have created your delegation set, you can use it to create a new hosted zone in Route 53. When you create the hosted zone, you will need to specify your custom domain name as the name servers for the zone. This will ensure that Route 53 uses your white label name servers as the authoritative name servers for your domain.

In summary, configuring white label name servers in AWS allows you to use your own custom domain name as the name servers for your hosted zone in Route 53. This can be useful if you want to have more control over your DNS resolution or if you want to use your own branding for your DNS services.
