Here,s why the other options are not as suitable:
A). Configure A records with different weights: While weights can influence traffic distribution, they wouldn,t automatically direct users based on region. Users might still access an unsuitable version due to various factors like caching.B. Traffic Management with Failover Pools: This solution is more complex and might not be necessary for basic version differentiation based on region. It,s often used for high availability scenarios with active-passive failover within a region.C. Latency-Based Traffic Steering: This works well for optimizing performance based on user location, but it wouldn,t automatically choose the appropriate version based on the deployed version in each region.DNAME records offer several advantages:
Simple and efficient: You can create DNAME records that redirect users to different "A" records based on their DNS query origin (region).
Flexible control: You can create separate DNAME records for each region, pointing to the specific "A" record of the deployed version in that region.
Automatic redirection: Users are automatically directed to the correct version based on their location, improving user experience and ensuring they access the intended content.
