To enable SSH communication between Web_EPG (Web Endpoint Group) and App_EPG (Application Endpoint Group), it’s necessary to apply a configuration that allows bidirectional communication while not restricting ports based on their directionality. By enabling “Apply Both Directions” and disabling “Reverse Filter Ports,” this ensures that the filter allows SSH packets to flow from Web_EPG to App_EPG and vice versa without any restrictions based on the port’s direction, which is essential for establishing an SSH session. References := ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )

 In Cisco ACI fabric, STP BPDUs are flooded in the bridge domain VLAN. This allows the BPDUs to be propagated throughout the fabric, maintaining the STP topology2.

 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.
