Explanation

FusionInsight is designed as an enterprise-grade big data platform with high availability at its core - it supports rolling upgrades and online expansion, meaning nodes can be upgraded or added while the cluster continues serving requests. This eliminates maintenance windows and ensures business continuity, which is a deliberate architectural goal of the platform.

Why B is wrong: "FALSE" would imply that service interruption is required, but FusionInsight specifically avoids this through its distributed, redundant architecture. Claiming downtime is required contradicts the platform's core enterprise design principle.

Memory tip: Think of FusionInsight like a highway with multiple lanes - you can repave one lane at a time while traffic keeps moving. "Fusion" = seamless continuity. If a big data platform required downtime for every upgrade, no enterprise would adopt it, so the answer is always going to favor zero-interruption design.
