Regarding a cloud cluster, which two upgrades can be performed using LCM? (Choose two.)

Life Cycle Manager (LCM) on Nutanix Clusters (NC2) on AWS is used to manage and upgrade the Nutanix software stack. This includes the hypervisor (AHV) and core software components like Nutanix Cluster Check (NCC). LCM inventories the cluster and provides recommendations for available software updates, which can then be applied with one-click simplicity. This ensures the cluster's software components are up-to-date. However, LCM does not manage the underlying bare-metal hardware firmware, as this is the responsibility of the cloud provider (AWS).

B. NBA: This is not a standard Nutanix component acronym. LCM updates well-defined Nutanix software, and NBA does not correspond to a known updatable module in this context.
C. BIOS: The BIOS is part of the server firmware. For NC2 on AWS, the underlying bare-metal instances are managed by AWS, which includes all firmware and BIOS updates.

2. Nutanix University. (2023). Nutanix Hybrid Cloud Fundamentals Courseware. Module: "Life Cycle Management". The course explains that LCM is the tool for upgrading the Nutanix software stack, including AHV and NCC.
