BMC (Baseboard Management Controller) updates can be applied per-node in Nutanix LCM, unlike AOS or AHV, which require cluster-wide upgrades.
* Option B (BMC) is correct:
* BMC firmwarecontrols remote management and power cycling of individual nodes.
* Updating BMCdoes not impact the entire clusterand can be done per node.
* Option A (AOS) is incorrect:
* AOS upgrades affect the entire clusterand require cluster-wide consistency.
* Option C (NCC) is incorrect:
* NCC updatesapply across all nodes simultaneously, ensuring uniformity in checks.
* Option D (AHV) is incorrect:
* AHV updates require coordinated upgrades across hoststo maintain VM availability.
