A solution for the data warehouse system must be created to provide disaster recovery between SQL03 and an Azure virtual machine named SQL04. You are designing the data warehouse. You need to recommen

SQL Server AlwaysOn Availability Groups provide high availability and disaster recovery by allowing databases to be replicated between SQL Server instances, including a hybrid configuration between on-premises and Azure virtual machines. This setup ensures data redundancy and failover capabilities across different locations, directly addressing the disaster recovery requirement between SQL03 and SQL04.

Hosting the data warehouse on an Azure virtual machine only specifies the location of one instance and does not inherently provide a disaster recovery solution between two specific SQL Server instances.

Azure HDInsight is a Hadoop-based analytics service and is not a direct solution for providing disaster recovery for SQL Server relational databases.

Azure DocumentDB, now part of Azure Cosmos DB, is a NoSQL database service, which is not suitable for a relational data warehouse system or for providing disaster recovery for SQL Server.
