CDIA Storage, Retrieval & Security Management 4 — Questions and Answers
Question 1: What is the key difference between a backup and an archive in document management?
- Backups use compression; archives do not
- Backups support recovery from failure; archives preserve records for long-term retention (Correct answer)
- Archives are encrypted; backups are plaintext
- Backups are stored offsite; archives are always onsite
Correct answer: Backups support recovery from failure; archives preserve records for long-term retention
Backups are for operational recovery after data loss, while archives preserve records for long-term compliance and historical reference.
Question 2: In access control for a document imaging system, what is a Role-Based Access Control (RBAC) model?
- Access determined by document creation date
- Access permissions assigned to roles that are then assigned to users (Correct answer)
- Access granted based on network IP range
- Access controlled by document file size
Correct answer: Access permissions assigned to roles that are then assigned to users
RBAC assigns permissions to defined roles (e.g., clerk, manager, auditor) and users inherit those permissions by role membership.
Question 3: Which standard defines requirements for electronic records management systems used in government and regulated industries?
- ISO 9001
- DoD 5015.2 (Correct answer)
- IEEE 802.3
- ANSI X9.17
Correct answer: DoD 5015.2
DoD 5015.2 is the Department of Defense standard for records management application design, widely adopted in government and regulated sectors.
Question 4: What does 'disaster recovery point objective (RPO)' define in a document storage context?
- The maximum time allowed to restore a system after failure
- The maximum acceptable amount of data loss measured in time (Correct answer)
- The geographic distance between primary and backup sites
- The number of backup copies required
Correct answer: The maximum acceptable amount of data loss measured in time
RPO defines how far back in time data can be lost during a disaster—e.g., an RPO of 4 hours means up to 4 hours of document changes may be lost.
Question 5: Which encryption approach protects documents while they are stored on disk, regardless of who accesses the storage media?
- Transport Layer Security (TLS)
- Encryption at rest (Correct answer)
- Hashing
- Steganography
Correct answer: Encryption at rest
Encryption at rest protects stored data by encrypting it on the storage medium, so stolen or improperly accessed media remains unreadable.
Question 6: A company needs to retrieve a specific version of a contract signed three years ago. Which system feature makes this possible?
- Full-text indexing
- Document version history with timestamped snapshots (Correct answer)
- Optical character recognition (OCR)
- Storage load balancing
Correct answer: Document version history with timestamped snapshots
Version history stores point-in-time snapshots of documents with timestamps, enabling retrieval of any prior version.
Question 7: Which technique reduces storage space by identifying and eliminating duplicate data blocks across a document repository?
- Compression
- Deduplication (Correct answer)
- Defragmentation
- Indexing
Correct answer: Deduplication
Deduplication identifies identical data blocks or files and stores only a single copy, with pointers replacing redundant copies.
