[All AWS-SysOps Questions]

An organization's security policy requires multiple copies of all critical data to be replicated across at least a primary and backup data center. The organization has decided to store some critical data on Amazon S3.
Which option should you implement to ensure this requirement is met?

  • A. Use the S3 copy API to replicate data between two S3 buckets in different regions
  • B. You do not need to implement anything since S3 data is automatically replicated between regions
  • C. Use the S3 copy API to replicate data between two S3 buckets in different facilities within an AWS Region
  • D. You do not need to implement anything since S3 data is automatically replicated between multiple facilities within an AWS Region
Show Suggested Answer Hide Answer
Suggested Answer: D 🗳️
You specify a region when you create your Amazon S3 bucket. Within that region, your objects are redundantly stored on multiple devices across multiple facilities. Please refer to Regional Products and Services for details of Amazon S3 service availability by region.
