Fusioninsight HD preparations before installation, what steps are included? (Multiple choice)

Question

Options

• AComplete the hardware installation
• BComplete node host operating system installation
• CPrepare tools and software. For example, Putty, LLD, Fusioninsight HD software installation
• DPrepare planning data. Such as network parameters and role deployment locations

• A

Explanation

All four options are correct because pre-installation preparation for FusionInsight HD is a comprehensive process that spans hardware, software, and planning dimensions - skipping any one of them would leave the environment unprepared for a successful deployment. A ensures the physical infrastructure (servers, networking, storage) is in place before any software touches it. B is required because FusionInsight HD runs on top of a configured OS (typically a supported Linux distribution), and the cluster nodes must be ready to accept the installation. C covers the client-side tooling needed to connect to and manage the nodes (e.g., PuTTY for SSH access, LLD for log collection, and the HD installer package itself). D ensures that critical deployment decisions - IP addresses, hostnames, subnet masks, and role assignments (NameNode, ResourceManager, etc.) - are documented before installation begins, preventing misconfigurations mid-deploy. Since there are no wrong choices here, the key exam insight is that preparation is holistic: think of it in four layers - physical → OS → tools → planning data - and you'll recall all four steps under pressure.
