Explanation
Option B is correct because NDU (Non-Disruptive Upgrade) is specifically designed to upgrade Dorado V6 controller software without requiring controller restarts or causing service interruptions. The upgrade process uses a rolling approach, updating software components while the array continues to serve I/O, ensuring continuous availability throughout the procedure.
Option A is wrong because it directly contradicts the core purpose of NDU. Requiring a controller restart would constitute a disruption, making it a standard disruptive upgrade rather than a non-disruptive one.
Memory tip: Break down the acronym - NDU means Non-Disruptive Upgrade. If controllers had to restart, the upgrade would be disruptive by definition, making "NDU" a contradiction in terms. When you see NDU on the exam, anchor your answer to the word "Non-Disruptive."
