An enterprise runs mission-critical stateful workloads on Compute Engine virtual machines in the us-central1 region using zonal Persistent Disks. The architecture team needs to establish a backup and disaster recovery strategy that satisfies several operational and compliance requirements:

StudyCertsus-east1 regionWhich solution should you recommend to meet these requirements?
Take scheduled instant snapshots of the Persistent Disks in us-central1 and set a Cloud Storage object lifecycle rule to transition instant snapshots to Archive storage after 90 days.
Configure Persistent Disk Asynchronous Replication (PD Async Replication) between us-central1 and us-east1 for both operational recovery and 3-year compliance data retention.
Create regionally scoped snapshot schedules restricted strictly to us-central1 to avoid cross-region network egress costs, and export snapshots older than 30 days to a single-region Coldline Cloud Storage bucket in us-central1.
Configure automated snapshot schedules on the Persistent Disks that create standard snapshots stored in a multi-region location (us) for daily operational recovery, and configure scheduled archive snapshots stored in multi-region us for long-term monthly compliance retention.

Compute Engine Persistent Disk snapshots are incremental point-in-time backups that capture block-level changes from persistent storage. Snapshots can be configured as either standard snapshots for short-term operational recovery or archive snapshots for low-cost, long-term data retention. They can be placed into regional or multi-regional Cloud Storage locations.
us) ensures that snapshots are automatically replicated across multiple regions, allowing immediate disk restoration in us-east1 during a regional outage in us-central1.This architecture leverages fully managed native Compute Engine capabilities (snapshot schedules, multi-region snapshot storage, and archive snapshot tiers) to satisfy RPO, cross-region disaster recovery, and long-term cost optimization with minimal operational overhead.
