Question

A company runs its critical storage application in the AWS Cloud. The application uses Amazon S3 in two AWS Regions. The company wants the application to send remote user data to the nearest S3 bucket with no public network congestion. The company also wants the application to fail over with the least amount of management of Amazon S3. Which solution will meet these requirements?

Options

  • AImplement an active-active design between the two Regions. Configure the application to use the
  • BUse an active-passive configuration with S3 Multi-Region Access Points. Create a global endpoint
  • CSend user data to the regional S3 endpoints closest to the user. Configure an S3 cross-account
  • DSet up Amazon S3 to use Multi-Region Access Points in an active-active configuration with a

Explanation

AWS S3 Multi-Region Access Points enable customers to use a single global endpoint for S3 bucket access across multiple AWS Regions, providing automatic routing to the nearest Region. This reduces public network congestion by directing user data to the closest S3 bucket and supports high availability with active-active configuration. Cross-Region Replication ensures data is replicated between buckets in different Regions, meeting the failover and resilience requirements with minimal management overhead. Option D aligns best with AWS's recommended approach to resilient, low-latency, and simplified multi-Region S3 access. Option A lacks the global endpoint and automatic failover. Option B incorrectly describes Multi- Region Access Points configuration and suggests global endpoints per Region, which is contradictory. Option C's cross-account replication adds complexity and does not provide a single global
