Which description regarding the initial APIC cluster discovery process is true?
Correct Answer: A
Each APIC instance in the cluster first discovers only the leaf switch to which it is directly connected. After the leaf switch is registered with the APIC, the APIC discovers all spine switches that are directly connected to the leaf switch. As each spine switch is registered, that APIC discovers all the leaf switches that are connected to that spine switch. This cascaded discovery allows the APIC to discover the entire fabric topology in a few simple steps. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/apic/sw/2- x/GSG/b_APIC_Getting_Started_Guide_Rel_2_x/b_APIC_Getting_Started_Guide_Rel_2_x_chap ter_0100.pdf
