Question

You have an on-premises multi-tier application named App1 that includes a web tier, an application tier, and a Microsoft SQL Server tier. All the tiers run on Hyper-V virtual machines. Your new disaster recovery plan requires that all business-critical applications can be recovered to Azure. You need to recommend a solution to fail over the database tier of App1 to Azure. The solution must provide the ability to test failover to Azure without affecting the current environment. What should you include in the recommendation?

Explanation

You can use Azure Site Recovery to test failover. You run a test failover to validate your replication and disaster recovery strategy, without any data loss or downtime. A test failover doesn't impact ongoing replication, or your production environment. You can run a test failover on a specific virtual machine (VM), or on a recovery plan containing multiple VMs. https://docs.microsoft.com/en-us/azure/site-recovery/site-recovery-test-failover-to-azure
