ACI Licensing APIC-CLUSTER-L4

[config]

Hi team, 

I am going to deploy aci multipod fabric using APIC-CLUSTER-L4 and N9K-C93600CD-GX as spine switches, two switches for each pod. 

Cisco writes that APIC-CLUSTER-L4 are now bundled with 2 (two) Advantage XF2 3-year-term licenses that can be applied to any switch that uses XF2 licenses. How many apic cluster licenses do I need for 4 spine switches? Are the licenses that come with the apic cluster enough or do I need additional licenses?

I believe you have your answer, but for anyone with the same question, the licenses included with the APIC cluster are for two switches, either Spine or Leaf.
