Answer: Amazon EFS, designed to replicate data across Availability Zones for high availability., Amazon S3, ensuring high availability through storage redundancy across multiple facilities.
The correct answers are Amazon Elastic File System (Amazon EFS) and Amazon S3. Amazon EFS is designed to provide high availability by automatically storing data across multiple Availability Zones within a region. This ensures that the file system remains available even if one Availability Zone experiences a failure. Similarly, Amazon S3 is built to offer high availability and durability by storing data across multiple devices and facilities. While S3 does not replicate data across Availability Zones by default, it does provide a highly durable storage solution that is available with a 99.999999999% (11 9's) durability guarantee for all storage classes.
