QuestionQ718

Content Domain 3: Cloud Technology and Services

A company wants its Amazon EC2 instances to operate in a highly available environment, even if there is a natural disaster in a particular geographic area.

Which solution achieves this goal?

  • A Use EC2 instances in multiple AWS Regions.
  • B Use EC2 instances in multiple edge locations.
  • C Use EC2 instances in the same Availability Zone but in different AWS Regions.
  • D Use Amazon CloudFront with the EC2 instances configured as the source.
Explanation

Running EC2 instances across multiple AWS Regions provides geographic redundancy so the application stays available even if an entire Region is affected by a natural disaster, since Regions are physically isolated from one another. Availability Zones within a single Region (or edge locations, which serve cached content rather than run EC2 instances) do not protect against a Region-wide disaster.
