20+ practice questions focused on Design business continuity solutions — one of the most tested topics on the Microsoft Azure Solutions Architect Expert AZ-305 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Design business continuity solutions PracticeA company runs a critical web application on Azure App Service in a single region. They need to achieve high availability across regions with automatic failover in the event of a regional outage. Which approach should they recommend?
Explanation: Azure Front Door provides global load balancing and automatic failover across multiple regions by routing traffic to the nearest healthy backend. For a critical web application requiring cross-region high availability, deploying App Service instances in multiple regions behind Front Door ensures seamless failover during a regional outage, as Front Door monitors endpoint health and redirects traffic away from failed regions.
A company wants to back up their Azure VMs (running Windows and Linux) to a Recovery Services vault. The backup data must be encrypted at rest using customer-managed keys. They also need to retain monthly backups for 5 years for compliance. Which configuration should they use?
Explanation: Azure Backup encrypts backup data using customer-managed keys by configuring encryption on the Recovery Services vault with a key from Azure Key Vault. ADE/DES are for VM disk encryption, not for backup data. The vault's CMK setting is the correct method.
A company runs a critical application that uses Azure SQL Managed Instance in the West Europe region. They need to ensure that the database remains available if a regional failure occurs. The solution must provide automatic failover with an RPO of less than 5 seconds and an RTO of less than 1 minute. The secondary region must also be able to serve read-only queries for reporting purposes. Which Azure service should they use?
Explanation: Auto-failover groups for Azure SQL Managed Instance provide automatic failover and readable secondaries, but they are designed for an RPO of 5 seconds and an RTO of about 1 hour. This does not satisfy the required RTO of <1 minute. To achieve the required RPO and RTO, a synchronous replica with automatic failover is needed, which is provided by SQL Server Always On Availability Groups on IaaS VMs (option C). This configuration can have an RPO of 0 (synchronous commit) and an RTO of seconds, and the secondary can be configured to accept read-only queries.
A company runs a critical web application on Azure VMs that uses Azure SQL Database. They need a disaster recovery solution that provides automatic failover to a secondary region with an RPO of 5 seconds and an RTO of 1 minute. The secondary region must also be able to serve read-only queries for reporting purposes. Which Azure SQL Database feature should they use?
Explanation: Active geo-replication with an auto-failover group is the correct choice because it provides automatic, asynchronous replication of data to a secondary region with an RPO of 5 seconds (typically under 5 seconds) and an RTO of 1 minute when the failover group is configured with a grace period. Additionally, the secondary replica can be used for read-only queries by connecting with ApplicationIntent=ReadOnly, meeting the reporting requirement.
A company runs a multi-tier application on Azure virtual machines (VMs) in the West US region. The application consists of a web tier, an application tier, and a database tier. They need to implement a disaster recovery plan to a secondary region (East US) with a recovery point objective (RPO) of 5 minutes and a recovery time objective (RTO) of 15 minutes. The VMs must be recovered in the correct order: database tier first, then application tier, then web tier. The company also wants to test the recovery process periodically without affecting production. They need to ensure that after failover, the VMs retain their IP addresses to minimize DNS propagation delays. Which combination of Azure Site Recovery features should they use?
Explanation: Azure Site Recovery supports a replication frequency of 5 minutes, which meets the 5-minute RPO. A recovery plan with manual ordering can enforce the correct startup sequence (database first, app tier, web tier). Although the option says 'rely on default IP assignment,' static IP mapping can be configured within the recovery plan to retain IP addresses after failover. Test failover is supported for non-disruptive drills. This combination meets all requirements, unlike other options that miss the RPO or ordering constraints.
