Question 1

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

Accepted Answer

Hard Disk Drive (HDD)

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

Write Once Read Many

Answer

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

Question 4

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

Accepted Answer

RAID 1

Answer

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

Question 5

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

Accepted Answer

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

Answer

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