DP-300 Question #317: Real Exam Question with Answer & Explanation

Question

You have an Azure subscription that contains three instances of SQL Server on Azure Virtual Machines. You plan to implement a disaster recovery solution. You need to be able to perform disaster recovery drills regularly. The solution must meet the following requirements: - Minimize administrative effort for the recovery drills. - Isolate the recovery environment from the production environment What should you use?

Options

• Anative Microsoft SQL Server backup
• BAzure Site Recovery
• CRecovery Services vaults
• DAzure Backup

Explanation

Azure Site Recovery (ASR) is the right choice because it is specifically designed for disaster recovery scenarios and includes built-in test failover functionality, which allows you to spin up a fully isolated recovery environment in a separate Azure virtual network without impacting production - perfectly meeting both requirements of minimizing admin effort and isolating the recovery environment.

Why the distractors are wrong:

• A. Native SQL Server backup requires significant manual effort to restore and configure environments for drills, making it administratively heavy and not isolation-friendly.
• C. Recovery Services vaults are a storage container used by both Azure Backup and ASR - they are not a solution on their own and don't directly provide DR drill capabilities.
• D. Azure Backup is focused on data backup and restoration, not disaster recovery orchestration; it lacks the automated, isolated test failover capability that DR drills require.

Memory tip: Think of ASR = "Always Safe Recovery" - it's the go-to Azure service whenever an exam question mentions disaster recovery drills, test failovers, or isolating recovery from production, as these are its signature features that distinguish it from basic backup solutions.
