Which cluster configuration is LCM unable to perform firmware upgrades against?

AFive-node

BThree-node

CTwo - node

DSingle---node

Show Suggested Answer

Suggested Answer: D

LCM (Lifecycle Manager) is a tool provided by Nutanix to automate software and firmware upgrades for Nutanix clusters. However, LCM is unable to perform firmware upgrades against a (D) Single-node cluster configuration.

This is because a single-node cluster does not have any redundancy, so there is no way to perform an upgrade without taking the entire cluster offline. In contrast, multi-node clusters can typically be upgraded in a rolling fashion, with one or more nodes being upgraded at a time while the rest of the cluster remains online.

LCM is capable of performing firmware upgrades against two-node, three-node, and five-node cluster configurations, as long as they meet the other requirements for LCM support (such as being on a supported AOS release and having the appropriate network connectivity).

Just to clarify, two-node setups are also supported.

It's definitely five-node clusters that are fine.

LCM can't do firmware upgrades on single-node clusters.

I’m leaning towards single-node as well, but I remember something about five-node clusters being tricky too.

I feel like two-node clusters might be the answer, but I can't recall the specifics from my notes.

I remember practicing a similar question, and I think it was about three-node clusters being the limit for LCM upgrades.

I think LCM struggles with firmware upgrades on single-node clusters, but I'm not entirely sure.

Okay, let me think this through. A physical control is something tangible that helps protect against threats, right? I'm leaning towards option A, but I'll double-check the definitions just to be sure.

Ah, the age-old battle of the cluster configurations. I bet LCM can handle them all, except for the single-node setup - that's like trying to herd cats!
