Explanation:
Box 1: Azure Backup
The backup of drive P must be application-consistent.
Azure Backup can be used for application-consistent backups of Azure VMs. Azure Backup creates recovery points that ensure all data required to restore the backup is available, including application data, Box 2: An enhanced policy that has selective disk backup enabled.
The backup of drive S must be crash-consistent.
For Azure crash-consistent backups, utilize the agentless multi-disk restore points feature of Azure Backup. This feature, available with the Enhanced VM backup policy, allows for backups of all disks attached to a VM without requiring agents or quiescing VM I/O for extended periods.
Azure Backup supports agentless VM backups by using multi-disk crash-consistent restore points (preview). The Enhanced VM backup policy now enables you to configure the consistency type of the backups (application-consistent restore points or crash-consistent restore points preview) for Azure VMs.
