What combination of Amazon Route 53 policies would provide location-specific services with redundant, backup connections?

1. Latency-based and Multivalue answer

2. CNAME and Geolocation

3. Failover and Geolocation

4. Simple and Latency-based

The correct answer is: Failover and Geolocation

The combination of Failover and Geolocation policies in Amazon Route 53 is particularly effective for providing location-specific services while ensuring redundancy and backup connections. Geolocation routing enables you to direct users to resources based on their geographic location. This is useful for delivering tailored content or services that are more relevant to specific regions. For instance, users from Europe can be routed to a server that offers content specific to that audience, which can improve user experience by reducing latency or directing them to legal/compliance-specific offerings. On the other hand, the Failover routing policy is designed to maintain availability. It allows you to set up primary and secondary resources, ensuring that if the primary resource (like a server in one region) fails, users are routed to a secondary resource (such as a backup server in another region). This is crucial for maintaining service availability, particularly during unexpected outages or disruptions. The combination of these two policies results in a robust solution: users are directed to the closest available resource based on their location, and if that resource becomes unavailable, they are seamlessly rerouted to a backup, ensuring both relevance and reliability in service delivery.
