You operate frontends in us-central1 and europe-west1 and need Cloud DNS to route users to the nearest region by geography (continent or country). Which Cloud DNS routing policy should you use?

The Geolocation (Geo) routing policy is designed to route users to resources based on their geographic location (continent, country, or region). This directly addresses the requirement to route users to the nearest frontend in us-central1 or europe-west1 based on geography. Weighted routing policy distributes traffic across multiple resources based on assigned weights, not geographic proximity. Failover routing policy is used for high availability, directing traffic to a healthy alternative if the primary resource fails. Multivalue answer without a routing policy returns all configured IP addresses, leaving the client to choose, which doesn't guarantee routing to the nearest region.
