Answer: Store the application data on a regional persistent disk. If an outage occurs, create an instance in another zone with this disk attached.
The correct answer is D. When using regional persistent disks in Google Cloud, the data is automatically replicated to two replicas across different zones within the region. This ensures high availability because, in the event of a zonal failure, you can directly attach the regional persistent disk to a VM in another zone without the need to create a snapshot or restore data from it. Hence, option D provides immediate data availability and minimal downtime, addressing the high-availability requirement effectively.
