An administrator manually applies operating-system patches to an NDB-managed database server outside NDB.

NDB’s one-click patching workflow tracks patch actions and the corresponding database-server state in the NDB control plane. If an administrator patches the operating system manually outside NDB, those changes bypass the managed workflow, so NDB metadata is not updated. The VM is not automatically rolled back, and NDB does not automatically refresh it from a Software Profile. Instead, the difference between the server’s actual configuration and NDB’s recorded state can affect later lifecycle operations and produce unexpected behavior. Nutanix explicitly warns administrators to avoid manual patching outside NDB for this reason and states that the metadata will not update. Therefore, option D is correct. The candidate file’s supplied answer C states the opposite of the official One-Click Patching guidance and has been corrected. Nutanix One-Click Patching documentation
