AWS Certified Cloud Practitioner (CLF-C01)- Amazon Route53 and DNS

The video tutorial provides an in-depth look at AWS Route 53, Amazon's managed DNS service. It explains how Route 53 translates domain names into IP addresses, making it easier for users to connect to internet applications. The tutorial covers the features and benefits of Route 53, including its ability to route traffic globally and perform health checks. It also details various routing policies such as simple, failover, geolocation, latency-based, and weighted routing. The video concludes with a practical demonstration of setting up Route 53, including creating a hosted zone and configuring a domain name to work with an elastic load balancer.

What is the primary function of AWS Route 53?

• To host virtual machines

• To manage cloud storage

• To provide a scalable DNS web service

• To monitor network traffic

Why is Route 53 named as such?

• It was named after a famous highway

• It operates on port 53, similar to DNS

• It supports 53 different routing policies

• It was the 53rd service launched by AWS

What is a hosted zone in Route 53?

• A virtual server for hosting applications

• A text file containing DNS records

• A security group for network access

• A storage bucket for data

Which routing policy would you use for directing traffic based on user location?

• Latency-based routing policy

• Geolocation routing policy

• Failover routing policy

• Simple routing policy

What is the purpose of a failover routing policy?

• To test new versions of a website

• To route traffic to a backup site during an outage

• To balance traffic across multiple servers

• To direct traffic based on user location

How does weighted routing policy assist in A/B testing?

• By routing traffic based on server health

• By directing all traffic to a single version

• By routing traffic to the nearest server

• By distributing traffic between versions based on specified weights

What is a key feature of multivalue answer routing?

• It balances load across regions

• It provides a single IP address for all queries

• It returns multiple healthy IP addresses

• It routes traffic based on user location

What is the first step in setting up a web server in AWS?

• Creating a hosted zone

• Launching an EC2 instance

• Registering a domain name

• Configuring a load balancer

Why is it beneficial to use a domain name instead of an elastic load balancer DNS name?

• It reduces costs

• It provides faster access

• It is easier to remember and better for company image

• It is more secure

What is the role of an alias record in Route 53?

• To provide backup DNS records

• To encrypt DNS queries

• To map domain names to AWS resources

• To connect to external DNS services
