Answer: Deploying instances across multiple AWS Regions
The correct answer is B, which is to use EC2 instances in multiple AWS Regions. This approach ensures high availability by distributing instances across different geographical locations. If a natural disaster occurs in one region, the instances in other regions will continue to operate, providing uninterrupted service. This method offers a higher level of fault tolerance and disaster recovery compared to deploying instances in a single Availability Zone or multiple edge locations, or using Amazon CloudFront with EC2 instances as the source.
