Windows server 2012 Practice Test

In Windows Server 2012, both ReFS (Resilient File System) and Storage Spaces are designed to enhance data availability and resilience.

ReFS is a file system that provides several important features for data integrity and availability. It includes a built-in mechanism for detecting and automatically correcting data corruption, ensuring that the data remains accessible and reliable over time. This is achieved through checksums that verify the integrity of the data and metadata, which helps to safeguard against bit rot and other types of data corruption.

Storage Spaces complements this by allowing you to create virtualized storage pools from physical disks. This feature enables users to combine hard drives into a single storage pool, which can then be managed through a simplified interface. Storage Spaces supports different resiliency options, such as mirroring and parity, which provide redundancy. This ensures that even if a physical disk fails, the data remains safe and accessible through the remaining disks in the pool.

Together, ReFS enhances the reliability of data storage by ensuring data integrity, while Storage Spaces offers innovative management and redundancy solutions. Their combination provides a robust framework for ensuring high availability and resilience of data, making option D the correct choice.
