Question 1

A company hosts a mission-critical, 3-tier application on Azure Virtual Machines (Web, App, and Database tiers).

The business continuity plan requires a Recovery Time Objective (RTO) of 2 hours and a Recovery Point Objective (RPO) of 15 minutes. In the event of a regional disaster, the application must be failed over to a secondary region.

Crucially, during failover, the Database VMs must boot first, followed by the App VMs, and finally the Web VMs. Custom PowerShell scripts must run automatically after the Database VMs boot to reconfigure connection strings.

Which disaster recovery solution should you recommend?

Accepted Answer

Identify the need for continuous replication (ASR) and orchestrated failover with boot orders/scripts (Recovery Plans).

Question 2
