Question 1

What is the key difference between object storage and block storage in a document imaging context?

Accepted Answer

Object storage stores data with metadata and a unique ID, while block storage divides data into fixed-size chunks

Answer

Object storage pairs data with rich metadata and a unique identifier for flexible retrieval, whereas block storage divides data into raw fixed-size blocks without inherent metadata.

Question 2

A healthcare organization must retain patient records for 10 years with no possibility of alteration. Which storage solution is most appropriate?

Accepted Answer

WORM-compliant optical or cloud storage

Answer

WORM-compliant storage prevents any modification or deletion, satisfying healthcare regulations like HIPAA that mandate immutable long-term record retention.

Question 3

What is 'deduplication' in the context of document imaging storage?

Accepted Answer

Eliminating redundant copies of identical data to reduce storage consumption

Answer

Deduplication identifies and removes identical data segments, storing only one copy and referencing it when duplicates are detected, significantly reducing storage usage.

Question 4

Which factor most directly influences the choice between NAS and SAN in a large document imaging deployment?

Accepted Answer

Whether file-level or block-level storage access is required

Answer

NAS provides file-level access over standard network protocols (NFS/SMB), while SAN provides block-level access via Fibre Channel or iSCSI, making access type the key differentiator.

Question 5

In document storage tiering, which tier is typically used for documents accessed only once or twice per year?

Accepted Answer

Tier 3 (Archive/Cold Storage)

Answer

Tier 3 archive or cold storage, often using tape or low-cost cloud, is designed for rarely accessed documents that must be retained for compliance or historical purposes.
