59. Route 53 Simple Routing Policy

If we choose simple routing policy we can only have one record with multiple IP addresses and we cant have any health checks. If we specify multiple values in a record, Route 53 returns all values to the user in a random order.  User making a DNS request to Route 53 and we have got two IP addresses ( & Route 53 just picks these in random orders.

Question 1:
As a Solutions Architect, you are building a WEB application configured using two EC2 instances. You would like to configure it to randomly route to each server using Route53.
Choose a routing policy that meets this requirement.
A. Simple routing policy
B. Weighted routing policy
C. Latency routing policy
D. Failover routing policy
Answer: A
Option 1 is the correct answer. Simple routing is used when a domain has a single resource that performs a specific function. Simple routing routes traffic randomly across multiple instances. Therefore, simple routing is sufficient for random routing.
Option 2 is incorrect. Weighted routing allows you to associate multiple resources with a single domain name (example.com) or subdomain name (acme.example.com) and set the routing weight for each resource. it is used to route traffic to multiple resources in proportions that you specify.
Option 3 is incorrect. Latency routing can improve user performance by routing requests to the AWS Region with the lowest network latency when you are hosting your application in multiple AWS Regions.
Option 4 is incorrect. Failover routing allows you to stop routing to anomalous resources and route traffic to healthy resources.
