Your development team has currently made changes to an application that is hosted in AWS. Currently, the application is in Production, and Route 53 is being used as the DNS service. The new version of the application has undergone testing and now needs to be promoted to a separate environment. They need an initial set of traffic to be directed to the new version of the application for testing before the final cutover can be made. Which of the following would you implement?

Answer options:

A.2 resource records based on the Simple Routing policy
B.1 resource record based on the Latency Routing policy
C.1 resource record based on the Geo-location Routing policy
D.2 resource records based on the Weighted Routing policy

Answer – D
The AWS Documentation mentions the following.
Weighted routing lets you associate multiple resources with a single domain name (example.com) or subdomain name (acme.example.com) and choose how much traffic is routed to each resource. This can be useful for various purposes, including load balancing and testing new versions of software.
Option A is incorrect since this is used to configure standard DNS records.
Option B is incorrect since this is used for resources in multiple AWS Regions, and you want to route traffic to the region that provides the best latency.
Option C is incorrect since this is used when you want to route traffic based on the location of your users.
