CDIA Storage, Retrieval & Security Management 3

Question 1

Which RAID level provides both striping and mirroring, offering a balance of performance and fault tolerance?

Accepted Answer

RAID 10

Answer

RAID 10 (1+0) combines mirroring and striping, tolerating multiple drive failures as long as no mirror loses both drives.

Question 2

In a document imaging system, what is 'version control' primarily designed to manage?

Accepted Answer

Successive edits to a document, preserving prior states

Answer

Version control tracks document revisions over time, allowing users to view, compare, or restore earlier document states.

Question 3

Which security principle dictates that users should only have access to the documents necessary for their job function?

Accepted Answer

Least privilege

Answer

The least privilege principle restricts user permissions to the minimum required to perform their tasks, reducing exposure from compromised accounts.

Question 4

What is the primary advantage of content-addressable storage (CAS) in a document archive?

Accepted Answer

Automatic deduplication by storing each unique content only once

Answer

CAS uses a hash of the content as the storage address, automatically preventing duplicate copies of identical documents.

Question 5

A healthcare organization must ensure patient document images remain unaltered after storage. Which technology best satisfies this requirement?

Accepted Answer

WORM (Write Once Read Many) storage

Answer

WORM storage physically or logically prevents modification or deletion of data after it is written, ensuring document integrity.
