 ## How it works
 
-When HA is enabled, all primary nodes in a cluster are provisioned in one availability zone for better latency between nodes. The HA replica nodes, which don't receive requests, are provisioned in a different zone, if the region supports multiple zones and has available capacity.
+When HA is enabled, Azure Cosmos DB for MongoDB vCore runs one replica node for each primary node in the cluster. The primary and its replica use synchronous replication. The service detects failures on primary nodes and fails over to the replica nodes with zero data loss. The MongoDB connection string remains the same.
 
-Even without HA enabled, each node has its own locally redundant storage (LRS) with three synchronous replicas maintained by Azure Storage service. If there's a single replica failure, the Azure Storage service detects the failure, and transparently re-creates the relevant data. For LRS storage durability, see metrics on [this page](../../../storage/common/storage-redundancy.md#summary-of-redundancy-options).
