Explanation
B (False) is correct because FusionInsight HD is designed to support post-installation configuration changes - administrators can and regularly do modify service parameters, role settings, and instance configurations through the FusionInsight Manager web UI without reinstalling the cluster. This flexibility is a core operational feature of enterprise Hadoop management platforms.
Why A is wrong: Stating that modifications are "not allowed" contradicts how cluster management software works in practice. Clusters require ongoing tuning for performance, capacity changes, and bug fixes; locking configuration after install would make the platform unmanageable in production.
Memory tip: Think of FusionInsight Manager like a car's dashboard - installing the car (cluster) doesn't mean you can never adjust the settings (heat, mirrors, speed limits). Post-install configuration is the norm, not the exception, for any enterprise data platform.
