Question 1

Which storage characteristic is most critical when selecting a system for real-time document retrieval in a high-traffic enterprise environment?

Accepted Answer

Low latency and high IOPS

Answer

Real-time retrieval in high-traffic environments demands low access latency and high IOPS to ensure users receive documents quickly without queuing delays.

Question 2

What is 'storage virtualization' in the context of an enterprise document management system?

Accepted Answer

Abstracting physical storage resources into a single logical pool manageable as one unit

Answer

Storage virtualization abstracts heterogeneous physical storage hardware into a unified logical pool, simplifying management and enabling seamless capacity expansion.

Question 3

For long-term digital preservation of archival documents, which file format and storage combination is generally recommended?

Accepted Answer

PDF/A on WORM-compliant storage with checksum validation

Answer

PDF/A is the ISO-standardized archival format, and pairing it with WORM storage and checksum validation ensures both format integrity and protection against alteration.

Question 4

What is 'storage replication' and how does it differ from backup in a document imaging system?

Accepted Answer

Replication continuously mirrors live data to another location; backup creates periodic point-in-time copies

Answer

Replication provides continuous or near-real-time synchronization of live data to a secondary site, while backup captures periodic snapshots that may lag behind current state.

Question 5

A company stores 50 million document images that are accessed less than once per year on average. Which storage approach is most cost-effective?

Accepted Answer

Tiered cold/archive storage such as tape or cloud glacier-class storage

Answer

Cold or archive storage tiers like tape or cloud glacier-class services offer the lowest cost per GB for rarely accessed data where retrieval speed is not critical.
