An administrator has been tasked with performingfirmware upgradesfor all Nutanix sites.

The Nutanix Life Cycle Manager (LCM) is designed to manage and automate firmware and software upgrades across Nutanix clusters. However, firmware upgrades via LCM are not supported for single-node clusters. This limitation is documented in the ECA course as well as in LCM’s official release notes and guides.

From the Nutanix Enterprise Cloud Administration (ECA) course materials:

“LCM does not support performing firmware upgrades on single-node clusters. These clusters require manual upgrades, and LCM will not list any available firmware updates for them, regardless of the firmware revision state.”

The other options:

A is incorrect; single-node clusters don’t have this limitation specifically for “one-disk” firmware upgrades—it’s a complete limitation for all firmware tasks in LCM.

B is misleading; LCM is supported in general for Nutanix clusters, just not for firmware tasks in single-node clusters.

D is incorrect because lack of internet connectivity would typically show an error related to download or connectivity issues, not complete absence of firmware updates.
