-In this quickstart, you create a cluster replica in another region for an Azure Cosmos DB for MongoDB vCore cluster for disaster recovery (DR) purposes. This replica cluster stores a copy of all of your MongoDB resources - databases, collections, and documents - in another Azure region. The replica cluster provides a unique endpoint for various tools and SDKs to connect to and could be promoted to become available for writes in case of the primary region outage.
