DP-300 Certification Practice Question #225

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?

Accepted Answer

To fail over a multi-tier Hyper-V application (including the SQL Server database tier) from on-premises to Azure while satisfying the requirement to test the failover without impacting the current production environment, Azure Site Recovery (ASR) is the appropriate solution. ASR provides a native "Test Failover" capability that spins up replicas of the on-premises virtual machines in an isolated Azure virtual network. This allows administrators to verify the disaster recovery plan, connectivity, and database integrity without disrupting active replication or the production on-premises environment.
