You have an ACI environment with three APICs, two spine switches, and four-leaf switches. You wipe and reboot all APICs first then leaf and spine switches one- by-one and successfully go through the Initial Setuo dialogue on the APIC 1 CIMC KVM console. When you log in to the APIC1 WebGUI, you notice that you do not see any directly connected leaf switches being discovered under Fabric > Inventory > Fabric Membership. What is the cause of the issue?
A. The leaf nodes were not erased properly, which caused a fabric parameters mismatch with the APIC1
B. Rebooting the APICs and the leaf and spine switches after wiping them is not required
C. You forgot to enter the TEP Pool value during the Initial Setup dialogue on APIC1
D. The same Fabric Name value should be used before after wiping all devices
