For shared L3Out network connectivity among different tenants in a Cisco ACI fabric, a common tenant is necessary. It provides a global space for defining resources like L3Outs once, which can then be utilized by multiple tenants, simplifying management and ensuring consistent policy application. References := ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )

 In a Cisco ACI Multi-Site setup, the ISN (Inter-Site Network) connects different ACI sites. For efficient multicast traffic routing, BIDIR-PIM (Bidirectional Protocol Independent Multicast) is configured throughout the ISN, which is why option B is correct. Increasing the ISN MTU (Maximum Transmission Unit) to support the maximum MTU sent by endpoints is crucial to prevent packet fragmentation or loss, making option C correct.

Options A, D, and E are not typically required for an ACI Multi-Site setup. Direct connectivity between Spine switches and ISN routers, as mentioned in options A and D, is usually established through leaf switches. Option E, enabling IGMPv3 on ISN routers, is more relevant for managing multicast subscriptions within a single site.

Removing pre-existing Fibre Channel over Ethernet (FCoE) configurations from Nexus devices is necessary to ensure compatibility with Cisco ACI mode. FCoE configurations are not supported in ACI mode, and their presence can hinder the migration process2.
