Which device replicates Broadcast, Unicast, and Multicast (BUM) frames to all remote sites in a Cisco ACI Multi-Site with multiple stretched bridge domains?
The correct answer is D. local spine that is elected the designated forwarder for each bridge domain. In this architecture, when an endpoint generates a BUM frame within a stretched bridge domain, the local leaf switch encapsulates the frame using VXLAN and forwards it to a multicast group (GIPo) associated with that bridge domain.

Question
Which device replicates Broadcast, Unicast, and Multicast (BUM) frames to all remote sites in a Cisco ACI Multi-Site with multiple stretched bridge domains?
Options
- Aremote spine node that translates the VNID to the locally significant value
- Breceiving leaf that learns the location for the sourced BUM traffic
- Csource leaf that floods the traffic to the specific multicast group or GIPo
- Dlocal spine that is elected the designated forwarder for each bridge domain

Explanation
In this architecture, when an endpoint generates a BUM frame within a stretched bridge domain, the local leaf switch encapsulates the frame using VXLAN and forwards it to a multicast group (GIPo) associated with that bridge domain. This ensures the frame reaches all relevant leaf and spine switches within the local site.
