CDIA Storage, Retrieval & Security Management 3 — Questions and Answers
Question 1: Which RAID level provides both striping and mirroring, offering a balance of performance and fault tolerance?
- RAID 0
- RAID 1
- RAID 5
- RAID 10 (Correct answer)
Correct answer: RAID 10
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?
- Software patch deployment schedules
- Successive edits to a document, preserving prior states (Correct answer)
- Hardware firmware upgrades
- User account provisioning changes
Correct answer: Successive edits to a document, preserving prior states
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?
- Separation of duties
- Defense in depth
- Least privilege (Correct answer)
- Need to know
Correct answer: Least privilege
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?
- Faster sequential read speeds
- Automatic deduplication by storing each unique content only once (Correct answer)
- Lower encryption overhead
- Simplified access control lists
Correct answer: Automatic deduplication by storing each unique content only once
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?
- Full-disk encryption
- WORM (Write Once Read Many) storage (Correct answer)
- Load balancing
- Delta compression
Correct answer: WORM (Write Once Read Many) storage
WORM storage physically or logically prevents modification or deletion of data after it is written, ensuring document integrity.
Question 6: When classifying documents for access control, which attribute is typically used to group documents with similar sensitivity levels?
- File size
- Document classification label (e.g., Confidential, Public) (Correct answer)
- Creation timestamp
- OCR accuracy score
Correct answer: Document classification label (e.g., Confidential, Public)
Classification labels group documents by sensitivity, enabling security policies to grant or restrict access based on those labels.
Question 7: Which retrieval method allows a user to find documents by drawing conceptual relationships between terms, even without exact keyword matches?
- Boolean search
- Semantic or concept-based search (Correct answer)
- Wildcard search
- Proximity search
Correct answer: Semantic or concept-based search
Semantic search uses natural language processing and ontologies to match documents based on meaning and context, not just literal keywords.
