Difficulty: EasyDesign Azure Backup Solutions

You are designing a backup solution for an Azure virtual machine. The solution must meet the following requirements:
- Backups must be available in a secondary region to protect against a primary region outage.
- You must be able to perform instant recovery from snapshots for up to 14 days.

Which two configurations should you choose? (Choose two.)

  1. A Recovery Services vault configured with Geo-Redundant Storage (GRS) and Cross-Region Restore (CRR) enabledAnswer
  2. An Enhanced backup policy with the instant restore retention set to 14 daysAnswer
  3. C
    A Standard backup policy with the instant restore retention set to 14 days
  4. D
    A Recovery Services vault configured with Locally Redundant Storage (LRS)

Answer

A Recovery Services vault configured with Geo-Redundant Storage (GRS) and Cross-Region Restore (CRR) enabled, and an Enhanced backup policy with the instant restore retention set to 14 days
To satisfy the requirements, you must use a Recovery Services vault configured with Geo-Redundant Storage (GRS) and Cross-Region Restore (CRR) enabled to ensure availability in the secondary region. Additionally, because the Standard backup policy subtype only supports up to 5 days of instant restore retention, you must use the Enhanced backup policy subtype to set the instant restore snapshot retention to 14 days.

Step-by-Step Solution

1
Determine the vault type and redundancy configuration required for regional resilience.
Identify that a Recovery Services vault with Geo-Redundant Storage (GRS) and Cross-Region Restore (CRR) enabled is required to access backups in the secondary region during a primary region outage.
Locally Redundant Storage (LRS) does not replicate outside the primary region.
2
Determine the policy subtype needed to support the instant recovery snapshot duration.
Identify that the Enhanced backup policy subtype is required because the Standard policy limits instant recovery snapshot retention to 5 days, whereas the requirements call for 14 days.
The Standard policy subtype has a hard limit of 5 days for instant restore snapshot retention.

Key Concept

Selecting appropriate Azure Backup vault redundancy and policy subtypes (Standard vs. Enhanced) to satisfy regional disaster recovery and long-term instant restore requirements.
