Explanation

B is correct because FusionInsight HD's dual-node HA (High Availability) management mechanism performs automatic Failover - when the primary node fails, the system detects the failure and promotes the standby node to primary without requiring manual intervention.

Why A is wrong: Stating that Failover must be done manually contradicts the core purpose of an HA mechanism. If administrators had to manually trigger Failover every time a node went down, the system would suffer significant downtime, defeating the point of having HA in the first place.

Memory tip: Think of HA as "Hands-off Automation" - the entire value proposition of a dual-node HA design is eliminating human intervention during failure events. If you see a question suggesting HA requires manual steps for basic Failover, that's almost always false.
