How does OCI ensure data durability in its storage services?

• A. By compressing data to save space
• B. By integrating with third-party backup solutions
• C. By replicating data across multiple physical disks and ensuring redundancy
• D. By utilizing SSDs for all data storage

Answer: (C)

Choosing to replicate data across multiple physical disks and ensure redundancy is a key strategy that Oracle Cloud Infrastructure (OCI) uses to guarantee data durability in its storage services. This approach means that even in the event of hardware failure or other issues with a particular storage device, the data remains accessible and intact. Data durability relies on the principle that multiple copies of the same data are stored in separate locations, thereby reducing the risk of data loss. In OCI, this redundancy might involve writing the same data across different physical disks within a data center or even across multiple geographical locations to provide additional protection against potential outages or data corruption. This method is fundamental in cloud storage solutions, as it not only safeguards against individual disk failures but also contributes to high availability and reliability, which are critical for businesses that depend on their data to be consistent and readily available at all times.
