Which of the following statements about AWS storage services is TRUE?

  1. They allow you to compute complex calculations.

  2. They replicate data to different data centers for protection.

  3. They provide exclusive access to one user.

  4. They are limited to physical hardware for storage.

The correct answer is: They replicate data to different data centers for protection.

The statement that they replicate data to different data centers for protection is accurate and reflects a key feature of several AWS storage services. For example, Amazon S3 (Simple Storage Service) automatically maintains multiple copies of data across different Availability Zones (AZs) within a region, providing redundancy and high durability. This replication helps ensure that even in the event of hardware failure or a disruption in one data center, the data remains safe and accessible from other locations within the AWS infrastructure. This characteristic is central to the design of AWS storage services, as data durability and availability are critical requirements for businesses relying on cloud storage solutions. It highlights a core advantage of using AWS, where built-in disaster recovery capabilities are part of the overall service architecture. The other statements don't accurately describe AWS storage services: they don't perform complex calculations, they don't grant exclusive access to one user (as multiple users can access data depending on permissions), and they are not limited to physical hardware since AWS utilizes a vast network of interconnected storage systems in the cloud. This makes the replication of data for protection a standout feature that enhances data resilience and availability in the AWS ecosystem.
