You are designing a backup solution for an Azure Virtual Machine that hosts a critical enterprise resource planning (ERP) application. The virtual machine is configured with Premium SSD v2 managed disks.
Your design must meet the following requirements:
* The Recovery Time Objective (RTO) for restoring backups from the last 7 days must be minimized by using local snapshots.
* Backups must remain available even if an entire Azure region experiences an outage.
* Daily backups must be retained in the vault for 180 days.
* Administrative effort and cost must be minimized.
Which two configurations should you include in the backup design? (Select two.)
- An Enhanced backup policy with the instant restore retention set to 7 daysCevap
- A Recovery Services vault configured with Geo-redundant storage (GRS) and Cross Region Restore enabledCevap
- CA Standard backup policy with the instant restore retention set to 7 days
- DA Recovery Services vault configured with Locally redundant storage (LRS)
Cevap
The correct configurations are using an Enhanced backup policy with the instant restore retention set to 7 days, and using a Recovery Services vault configured with Geo-redundant storage (GRS) and Cross Region Restore enabled.
To support local snapshot retention of 7 days (instant restore) and back up a VM using Premium SSD v2 managed disks, you must use an Enhanced backup policy. Standard backup policies only support up to 5 days of instant restore retention and do not support Premium SSD v2 disks. To ensure backup availability during a regional outage, the Recovery Services vault must be configured with Geo-redundant storage (GRS) and Cross Region Restore (CRR) enabled, allowing you to restore data in the secondary region.
