AZ-305 Question 118
Select 2An e-commerce company runs several Windows and Linux virtual machines (VMs) in Azure to host their online store. They want to implement a cost-effective backup solution that enables file-level restores within 14 days of data loss or corruption. Additionally, they require the ability to fail over to a secondary Azure region if the primary site experiences a major outage. Which two options should you include in your design to meet these requirements?
- A
Use Azure Backup to create daily VM backups in a Recovery Services vault
- B
Configure ephemeral OS disks for all VMs to reduce snapshot storage costs
- C
Implement Azure Site Recovery for replication of VMs to a secondary region
- D
Use Azure Key Vault to store daily snapshots for file-level restore
Show answer and explanation
Correct answers: A, C
Explanation
The key to meeting the organization's requirements is a combination of Azure Backup for daily VM backups and file-level restores, and Azure Site Recovery for region-level failover. Azure Backup manages short-term retention needs (14 days) and provides flexible restore options. Azure Site Recovery replicates workloads to a secondary region to protect against regional disasters. For more details, refer to Azure official documentation on VM backup (https://learn.microsoft.com/azure/backup/backup-overview) and Azure Site Recovery (https://learn.microsoft.com/azure/site-recovery/site-recovery-overview).
- A. Correct.
Option 1 is correct. Azure Backup provides a straightforward way to create and manage daily VM-level backups. It allows you to configure retention policies (e.g., 14 days) and perform file-level restores, which meets the requirement for restoring data from accidental deletions or corruption.
- B. Incorrect.
Option 2 is incorrect. While ephemeral OS disks can help improve performance and reduce costs, they do not support backup through Azure Backup. Ephemeral disks store data locally on the host, making them unsuitable for persistent backups in a Recovery Services vault.
- C. Correct.
Option 3 is correct. Azure Site Recovery is the recommended Azure solution for disaster recovery scenarios. It replicates workloads to a secondary region, providing a way to fail over in case of a regional outage. This satisfies the requirement for region-level disaster recovery.
- D. Incorrect.
Option 4 is incorrect. Azure Key Vault is used to store secrets, keys, and certificates. It is not a repository for VM snapshots or file backups. Daily snapshot-based backups for file-level restore should be handled by Azure Backup rather than Key Vault.
