Fusionlnsight Manager supports large-scale cluster installation and deployment, monitoring, alarming, user management, rights management, auditing, service management, health check, problem location, upgrade, and patching.

The statement accurately describes the core functionalities of FusionInsight Manager. FusionInsight Manager is the centralized Operations and Maintenance (O&M) and management component of the Huawei FusionInsight HD big data platform. Its primary purpose is to simplify the lifecycle management of large-scale big data clusters. The functions listed—from initial installation and deployment to ongoing monitoring, user management, security auditing, service configuration, health checks, and software lifecycle tasks like upgrades and patching—are all integral features of this management system.

The option "False" is incorrect because the statement provides a comprehensive and accurate list of the key capabilities provided by FusionInsight Manager. To state that it is false would be to incorrectly deny that FusionInsight Manager performs these essential O&M tasks, which contradicts its fundamental design and purpose as documented by the vendor.

1. Huawei FusionInsight HD Product Documentation: In various versions of the FusionInsight HD Administrator Guide and Product Description, the role of FusionInsight Manager is explicitly defined. For instance, the documentation outlines its capabilities in sections dedicated to O&M.
