 When geo-replication is enabled, and if one replica isn't accessible, you can let your application failover to another replica for improved resiliency. App Configuration provider libraries have built-in failover support by accepting multiple replica endpoints. You can provide a list of your replica endpoints in the order of the most preferred to the least preferred endpoint. When the current endpoint isn't accessible, the provider library will fail over to a less preferred endpoint, but it will try to connect to the more preferred endpoints from time to time. When a more preferred endpoint becomes available, it will switch to it for future requests.
 
-Assuming you have an application using Azure App Configuration, you can update it as the following sample code to take advantage of the failover feature. You can either provide a list of endpoints for AAD authentication or a list of connection strings for access key-based authentication.
