Exam 300-420 topic 1 question 54 discussion

Client mulicast or receiver resides inside overlay. Both for source. D is correct. See page # 87 https://www.cisco.com/c/dam/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/deploy-guide/cisco-dna-center-sd-access-wl-dg.pdf

D is correct - please, refer to: Multicast traffic is transported in the overlay, in the EID space, for both wired and wireless clients https://www.ciscolive.com/c/dam/r/ciscolive/us/docs/2018/pdf/BRKEWN-2020.pdf

A follows the CBT Nuggets explanation

i will go with PIM SSM in the underlay as first things to do. https://community.cisco.com/t5/networking-knowledge-base/cisco-sd-access-multicast/ta-p/4068110

Answer is C. CCNP Enterprise Design Official Cert Guide ENSLD 300-420 Ch 10 : SD-Access Design page 340 "Both PIM Source-Specific Multicast(SSM) and PIM-Sparse Mode are supported with SD-Access. When using IP multicast in the overlay, the use of a RP is required."

Provided explanation is clear - D

Luis Jurado is right. D is correct ulticast traffic is transported in the overlay, in the EID space, for both wired and wireless clients page 113 of his link

Am assuming we are talking about the overlay in which case i think it is C. "Multicast sources can be supported both inside and outside the SD-Access fabric. With PIM implementations, a rendezvous point (RP) is used on the border for all multicast clients in the overlay. The multicast protocol configurations can be done within Cisco DNA Center.Both PIM Source-Specific Multicast (SSM) and PIM–Sparse Mode are supported with SD-Access. When using IP multicast in the overlay, the use of a RP is required. Multicast Source Discovery Protocol (MSDP) can be used for RP redundancy, if desired"
