Start the firmware upgrade on the spine upgrade group and then proceed with the other two groups.
C. Upgrade the APIC controllers by selecting the desired firmware and choosing Upgrade Now.

Selected Answer: B

It is not C, because Spines and leaves should be upgraded separately to maintain stability. It is B: This method aligns with Cisco ACI best practices, which recommend grouping nodes based on their roles and upgrading them sequentially to maintain redundancy and minimize downtime.
