Best Disaster Recovery Option for Natural Disasters

A.

All the given options can contribute to disaster recovery; however, to meet the requirement of little to no downtime in the event of a natural disaster, the BEST option would be C. Configure geo-redundancy.

Here's why:

A. Configure availability zones: Availability zones are physical data centers within a cloud region. Each availability zone is isolated from other availability zones, and they provide high availability and fault tolerance. However, if a natural disaster affects the entire region, availability zones would not be a suitable option to avoid downtime.

B. Configure high availability: High availability (HA) is a configuration that ensures applications or services are available with minimal downtime. This can be achieved through redundant components, load balancing, and failover mechanisms. While HA can reduce downtime caused by hardware or software failure, it may not be sufficient to avoid downtime in the event of a natural disaster.

C. Configure geo-redundancy: Geo-redundancy is a disaster recovery strategy that involves duplicating data and applications across multiple geographic locations. If a natural disaster occurs, the backup site can take over, and there will be no downtime. Geo-redundancy is the BEST option for minimizing downtime in the event of a natural disaster.

D. Configure auto-scaling: Auto-scaling is a feature that allows applications or services to automatically adjust their capacity based on demand. Auto-scaling can help avoid downtime caused by overload or traffic spikes, but it may not be relevant in the context of natural disasters.

In summary, the BEST option to meet the requirement of little to no downtime in the event of a natural disaster is to configure geo-redundancy.
