CDIA Storage, Retrieval & Security Management 2 — Questions and Answers
Question 1: Which storage tiering strategy automatically moves documents from high-performance to lower-cost storage based on access frequency?
- Hierarchical Storage Management (HSM) (Correct answer)
- RAID striping
- Content-addressable storage
- Journaling file system
Correct answer: Hierarchical Storage Management (HSM)
HSM automatically migrates data between storage tiers based on predefined policies such as access frequency and age.
Question 2: In a document imaging system, what does the term 'dark archive' refer to?
- An archive stored without indexing metadata
- A long-term preservation repository not accessible for daily retrieval (Correct answer)
- An encrypted backup with no key management
- A write-once optical storage system
Correct answer: A long-term preservation repository not accessible for daily retrieval
A dark archive is a preservation copy kept offline or restricted, not used for routine retrieval, to protect against corruption of the primary archive.
Question 3: Which authentication method provides the strongest access control for a document management system?
- Single-factor password
- Multi-factor authentication (MFA) (Correct answer)
- IP address filtering alone
- Security questions
Correct answer: Multi-factor authentication (MFA)
MFA combines two or more independent credentials (something you know, have, or are), significantly reducing unauthorized access risk.
Question 4: What is the primary purpose of a document retention schedule in a records management system?
- To define storage media formats
- To specify how long records must be kept and when they must be destroyed (Correct answer)
- To encrypt documents at rest
- To determine retrieval response times
Correct answer: To specify how long records must be kept and when they must be destroyed
A retention schedule establishes legally and operationally mandated timeframes for keeping records, followed by authorized disposition.
Question 5: Which indexing approach stores a document's content words in a searchable database to enable full-text search?
- Metadata indexing
- Inverted index (Correct answer)
- Hash-based indexing
- Sequential file indexing
Correct answer: Inverted index
An inverted index maps each word to the documents containing it, enabling efficient full-text search across large repositories.
Question 6: In document imaging security, what does 'chain of custody' primarily ensure?
- Unbroken audit trail documenting who handled a document and when (Correct answer)
- Physical security of storage media during transport
- Encryption key handoff between administrators
- Sequential version numbering of edited documents
Correct answer: Unbroken audit trail documenting who handled a document and when
Chain of custody maintains a documented, unbroken record of document possession and handling, critical for legal admissibility.
Question 7: What storage format is most appropriate for long-term archival of scanned documents requiring guaranteed readability decades later?
- Proprietary DMS format
- PDF/A (ISO 19005) (Correct answer)
- TIFF with LZW compression
- JPEG 2000
Correct answer: PDF/A (ISO 19005)
PDF/A is an ISO-standardized subset of PDF designed specifically for long-term archival, prohibiting features that may hinder future rendering.
