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 daysAnswer
- A Recovery Services vault configured with Geo-redundant storage (GRS) and Cross Region Restore enabledAnswer
- CA Standard backup policy with the instant restore retention set to 7 days
- DA Recovery Services vault configured with Locally redundant storage (LRS)
Answer
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.

Key Concept
Designing Azure Virtual Machine backup solutions using Recovery Services vaults and backup policies, aligning snapshot and vault-level retention with recovery objectives and storage redundancy constraints.
