A company is planning the backup strategy for a group of Azure Virtual Machines that run a payroll processing application. The virtual machines use Premium SSD v2 managed disks. The backup design must meet the following requirements:
- Achieve a Recovery Point Objective (RPO) of 8 hours.
- Retain backup snapshots in the local storage tier for 5 days to allow immediate recovery.
- Ensure backup data remains available if an entire availability zone in the primary region fails, without replicating data to a secondary region.
Which two configuration settings should you include in the backup design?
- A Recovery Services vault configured with zone-redundant storage (ZRS)Answer
- An Enhanced backup policy with a schedule of every 8 hours and snapshot retention of 5 daysAnswer
- CA Recovery Services vault configured with locally redundant storage (LRS)
- DA Standard backup policy with vault-tier retention set to 5 days
Answer
To meet the requirements, you must use a Recovery Services vault configured with zone-redundant storage (ZRS) and an Enhanced backup policy configured with an 8-hour schedule and 5 days of snapshot retention.
The correct solution includes configuring a Recovery Services vault with zone-redundant storage (ZRS) to protect against availability zone failures without replicating to a secondary region, and implementing an Enhanced backup policy to support Premium SSD v2, enable an 8-hour backup frequency, and specify 5 days of snapshot retention for instant recovery.
