Top Route 53 Interview Questions and Answers - Thinkcloudly

What is the AWS Route 53?

AWS’s Route 53 is a scalable and easy-to-use domain name system (DNS) hosting service. DNS services help translate your domain names into IP addresses so that you can communicate across the internet, just like translating someone’s name into their phone number so you can reach them on the phone.

How can we use Route 53 to route users?

We can use Route 53 to route users to your website [by translating human-readable names into numerical IP addresses] or as a name server for your domain [by storing all of the information that defines your domain in the Route 53 DNS naming system].

When preparing for an interview on DNS-related topics, you’ll likely encounter questions about Route 53 in AWS. Route 53 is AWS’s scalable and highly available DNS web service, playing a pivotal role in managing domain names and directing traffic efficiently across various AWS resources. To excel in your interview, it’s crucial to understand what Route 53 is and be prepared to answer questions about its key features, its integration with other AWS services, and its role in ensuring the reliability and availability of your applications and websites hosted on AWS infrastructure.

 What are the actions performed by Route 53?

There are primarily two actions performed.

  • Based on information in its hosted zone files, AWS serves as a “Domain Name System Server” by allocating specific IP addresses to each domain name. Clients may now quickly access internet resources by name as opposed to IPv4 or IPv6 addresses, which are more challenging for people to remember.
  • Clients can manage records on their own defined list rather than relying on external data sources by becoming aware of all hosted zones being supplied out of Route 53’s servers when they seek to connect, utilizing the public DNS servers offered by Amazon Web Services (AWS).

What are Name servers?

What are zones?

Zones are the grouping of one or more hosted zones with the same namespace in our AWS account.

As an illustration, if we have two different websites, www1, and www2, they would be kept in two different hosted zones in our AWS account.

What is a DNS name or alias?

The human-readable record we want to link to an endpoint in Route 53 is called a DNS name (e.g., ).

For instance, if someone types into their web browser’s address bar, Route 53 will provide the IP address corresponding to that domain name.
