Microsoft Azure Architect Design (AZ-304) Practice Test

What solution meets the goal of migrating virtual machine disks to Azure while keeping the VMs available?

1. Implementing an Azure Storage account with blob service

2. Implementing a Recovery Services vault with Azure Site Recovery

3. Using Azure Storage account with Data Migration Assistant

4. Implementing an Azure Storage account with AzCopy

The correct answer is: Implementing a Recovery Services vault with Azure Site Recovery

Implementing a Recovery Services vault with Azure Site Recovery is the best solution for migrating virtual machine disks to Azure while ensuring that the VMs remain available throughout the migration process. Azure Site Recovery is specifically designed for disaster recovery and migration scenarios. It allows you to replicate your on-premises VMs to Azure, enabling you to conduct a seamless migration while keeping the original VMs running. When you use Azure Site Recovery, the replication process is continuous, meaning that any changes made to the VMs will be captured and replicated to Azure. Once the migration is completed and the VMs are fully replicated, you can perform a failover, which brings the replicated VMs online in Azure. This minimizes downtime and ensures that your applications remain available during the migration period. Other options, such as implementing an Azure Storage account with blob service, do not inherently provide the necessary functionality for keeping VMs available during the migration. While Data Migration Assistant is useful for assessing and migrating databases, it does not cater to the migration of virtual machines specific to maintaining availability. AzCopy, while a powerful tool for transferring data to Azure Storage, does not support the full VM replication and migration capabilities that Azure Site Recovery provides. Therefore, using the Recovery Services vault with Azure Site Recovery is
