D. PIM sparse mode with RP located at the hub

PIM (Protocol Independent Multicast) sparse mode is typically recommended for large-scale networks, such as the one described in this scenario, where multicast traffic needs to be efficiently distributed across the WAN. In the PIM sparse mode, the RP (Rendezvous Point) acts as a meeting point for multicast sources and receivers. By locating the RP at the hub (headquarters site) in this setup, it centralizes the control and management of multicast traffic. The remote sites can function as PIM sparse mode routers and join the multicast group through the RP at the hub. This design helps optimize the distribution of multicast traffic by minimizing unnecessary traffic replication across the WAN. Therefore, using PIM sparse mode with the RP located at the hub would be the appropriate multicast routing design for Company XYZ's network in this scenario.

The RP is a control-plane operation that should be placed in the core of the network or close to the IP Multicast sources on a pair of Layer 3 switches or routers. It is normally at the Hub end. https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/Feb2016/CVD-IWANDesignGuide-FEB16.pdf https://learningnetwork.cisco.com/s/question/0D53i00000KszXhCAJ/multicast-over-dmvpn-possible-solutions

RP is Rendevous Point, it's natual location will be Hub.

B. RP is a designated router that manages multicast group membership information and controls the distribution of multicast traffic in a network.

D , as spoke to spoke traffic goes through Hub
