Question 1

A legal firm requires that documents sent externally cannot be forwarded or printed by recipients. Which technology enforces this at the document level?

Accepted Answer

Information Rights Management (IRM)

Answer

IRM embeds usage restrictions directly in the document file, enforcing permissions regardless of where the file travels.

Question 2

What is the key advantage of using a microservices architecture for a document processing platform compared to a monolithic design?

Accepted Answer

Independent scaling and deployment of each processing function

Answer

Microservices allow each function (OCR, classification, rendering) to scale and be deployed independently based on its own demand.

Question 3

In a multi-tenant document management SaaS platform, which isolation strategy provides the strongest data separation between customers?

Accepted Answer

Separate database instance per tenant

Answer

Separate database instances provide the strongest isolation because a misconfiguration or breach in one tenant's data cannot affect another.

Question 4

Which caching strategy is most appropriate for a document thumbnail service that generates previews on first request?

Accepted Answer

Cache-aside (lazy loading) pattern

Answer

Cache-aside loads the thumbnail into cache only on the first request, avoiding pre-generating previews for documents that are never viewed.

Question 5

A document workflow system must resume processing exactly where it left off after a server crash. Which design pattern best supports this?

Accepted Answer

Saga pattern with persistent checkpointing

Answer

The Saga pattern with persistent checkpointing records each completed step so the workflow can resume from the last checkpoint after a failure.
