Configure Route 53 Hosted Zones for Domain Name Resonance

Answer - C and D.

The AWS Documentation mentions the following.

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.

To create a reusable delegation set, you can use the Route 53 API, the AWS CLI, or one of the AWS SDKs.

To ensure that hosted zones created in Route 53 have name servers that resonate with your domain name, you can use a Reusable delegation set. A Reusable delegation set is a set of four Amazon Route 53 name servers that you can use as the delegated name servers for multiple hosted zones. When you create a Reusable delegation set, you specify a name for the delegation set, and you can associate it with multiple hosted zones.

To achieve this, you can use two of the options given:

B. Create a Reusable delegation set using the AWS Console D. Create a Reusable delegation set using the AWS CLI

To create a Reusable delegation set using the AWS Console, follow these steps:

1. Log in to the AWS Management Console and navigate to the Route 53 console.
2. Click on the "Reusable delegation sets" option in the left-hand navigation pane.
3. Click on the "Create reusable delegation set" button.
4. Enter a name for the delegation set.
5. Add the IP addresses of the four name servers that you want to use for the delegation set.
6. Click on the "Create" button.

To create a Reusable delegation set using the AWS CLI, follow these steps:

1. Install and configure the AWS CLI on your local machine.

2. Open a command prompt or terminal and enter the following command to create a delegation set:

   aws route53 create-reusable-delegation-set --caller-reference <unique string> --name <delegation set name> --child-nameserver-count 4 --hosted-zone-id <your hosted zone ID> --nameservers <list of four IP addresses>

   Replace <unique string> with a unique string that you choose, <delegation set name> with a name for the delegation set, <your hosted zone ID> with the ID of the hosted zone that you want to associate with the delegation set, and <list of four IP addresses> with a comma-separated list of four IP addresses that you want to use for the name servers.

3. Press Enter to execute the command.

Once you have created a Reusable delegation set, you can associate it with multiple hosted zones. When you create a new hosted zone, you can select the Reusable delegation set that you want to use for the name servers, and Route 53 will automatically assign the four name servers from the delegation set to the hosted zone. This ensures that the name servers for your hosted zones have names that resonate with your domain name.

So, the correct answers to this question are:

B. Create a Reusable delegation set using the AWS Console. D. Create a Reusable delegation set using the AWS CLI.
