Before registering a database server VM to NDB, an administrator must verify that all required software (e.g., database engine, OS dependencies) and configuration settings (e.g., WinRM for Windows, SSH for Linux) are in place. NDB provides a prerequisites script, which can be run on the target VM to check these dependencies automatically. This script ensures compatibility and readiness, reducing registration failures.
Option A (LCM - Lifecycle Manager) is incorrect because LCM is used for cluster upgrades, not VM prerequisite checks.
Option B (Upgrade Software) is incorrect as it applies to updating existing software, not initial dependency verification.
Option C (Prerequisites script) is correct as it is the designated tool for pre-registration validation.
Option D (NCC - Nutanix Cluster Check) is incorrect because NCC checks cluster health, not VM-specific software dependencies.
