Explanation

Note: The stated correct answer of B and D appears questionable based on standard AEM architecture principles. The most widely accepted correct answers for this question are B and C - this may be an error in your source material. Here's the breakdown:

Why B (Fail Safeness) is correct: A multi-author setup provides redundancy - if one Author instance goes down, authors can continue working on another node. High availability is one of the primary architectural drivers for running multiple Author instances.

Why C (Number of Parallel Authors) is the likely second correct answer, not D: When many authors work concurrently, a single Author instance becomes a performance bottleneck. Distributing the load across multiple instances is a core justification for multi-author architecture. This is a standard AEM design consideration.

Why D (Cache Efficiency on the Dispatcher) is suspect: The Dispatcher primarily caches content for Publish instances, not Author instances. It's a Publish-tier concern and would not typically drive Author-tier architecture decisions.

Why A and E are wrong: Website traffic (A) is handled by Publish/Dispatcher layers, not Author servers. Types of author actions (E) might influence hardware sizing on a single instance but don't inherently require multiple Author instances.

Memory tip: Think "Author problems get Author solutions" - only factors that directly stress the Author tier (uptime risk, concurrent user load) justify adding Author instances. Dispatcher and traffic concerns belong to the Publish/Delivery tier.

I'd recommend cross-checking this question against official Adobe AEM 6.5 documentation or another practice exam source.
