  1. Which storage technology uses spinning magnetic platters and mechanical read/write heads to store document images?

    Answer: Hard Disk Drive (HDD)

    Hard Disk Drives (HDDs) use spinning magnetic platters with mechanical read/write heads, making them cost-effective for large-volume document storage.

  2. In a document imaging system, what is 'hierarchical storage management' (HSM)?

    Answer: An automated process that migrates data between storage tiers based on usage patterns

    HSM automatically moves data between high-performance and lower-cost storage tiers based on access frequency and defined policies.

  3. What does 'WORM' storage stand for in document imaging?

    Answer: Write Once Read Many

    WORM (Write Once Read Many) storage prevents modification or deletion of stored documents, making it ideal for compliance and legal record retention.

  4. Which RAID level provides disk mirroring without striping, offering the highest redundancy for two drives?

    Answer: RAID 1

    RAID 1 mirrors data across two drives exactly, providing full redundancy so that if one drive fails, the other contains a complete copy.

  5. What is the primary advantage of using a Content Addressable Storage (CAS) system for document imaging?

    Answer: Documents are retrieved by their content hash rather than file path, ensuring integrity

    CAS assigns a unique hash to each document based on its content, enabling fast retrieval by content identifier and verifying data integrity on access.

  6. In cloud storage for document imaging, what does 'eventual consistency' mean?

    Answer: All nodes will reflect the same data after a period of time, but may temporarily diverge

    Eventual consistency means distributed storage nodes will converge to the same data state over time, though brief inconsistencies may exist immediately after a write.

  7. Which storage metric best describes how quickly a storage system can begin delivering data after a request is made?

    Answer: Latency

    Latency measures the delay between initiating a storage request and receiving the first byte of data, directly impacting user experience in document retrieval.
