Question 1

When designing disaster recovery for a document repository, what does an RPO (Recovery Point Objective) of 15 minutes require?

Accepted Answer

Backups or replication must capture changes at least every 15 minutes

Answer

RPO defines the maximum acceptable data loss window; a 15-minute RPO requires that backups or continuous replication run at least that frequently.

Question 2

A healthcare document system must ensure that patient records are encrypted both at rest and in transit. Which combination achieves this?

Accepted Answer

AES-256 for storage and TLS 1.2+ for network transport

Answer

AES-256 is the industry standard for encrypting stored data, while TLS 1.2+ secures data moving across networks, satisfying HIPAA encryption requirements.

Question 3

Which document system design consideration is most critical when planning for a 10x increase in concurrent users?

Accepted Answer

Horizontal scalability of stateless application tiers

Answer

Horizontally scaling stateless application tiers allows the system to handle more concurrent users by adding nodes without architectural changes.

Question 4

In a document imaging workflow, what is the function of a document capture server?

Accepted Answer

Receive scanned images, apply preprocessing, and route them to the appropriate workflow

Answer

A document capture server ingests raw scanned images, applies cleanup (deskew, despeckle, crop), and directs files to downstream classification or indexing workflows.

Question 5

What is the primary risk of using file system folders as the sole organizational structure in a large-scale document management system?

Accepted Answer

Folder structures are rigid and cannot represent multi-dimensional relationships between documents

Answer

Folder hierarchies impose a single classification path; documents with multiple attributes or relationships cannot be represented without duplication or complex workarounds.
