Which statements about the implementation of multicast in NSX-T Data Center are true? (Choose two)

In the context of implementing multicast in NSX-T Data Center, the statement regarding the use of PIM Sparse-Mode for multicast routing is accurate. PIM Sparse-Mode (Protocol Independent Multicast Sparse Mode) is designed for environments where receivers are sporadically distributed across a network. It establishes efficient multicast routing by requiring an explicit join from receivers to the multicast group, which minimizes unnecessary traffic on the network until there are actual subscribers. This mode is particularly advantageous for large, dynamic networks where maintaining efficient multicast transmission is critical.

Additionally, the use of IGMP Snooping is also significant in the multicast implementation. IGMP Snooping allows the switching infrastructure to listen to IGMP (Internet Group Management Protocol) messages between hosts and routers. By doing so, it dynamically builds multicast forwarding tables, which significantly optimizes multicast traffic handling and ensures that multicast packets are only sent to the ports that have interested receivers. This not only enhances network efficiency but also reduces unnecessary bandwidth consumption.

Choosing these aspects for the implementation of multicast in NSX-T underscores the importance of both efficient routing protocols and the means of managing traffic within the network effectively.
