Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 211

Which protocol is used to propagate multicast join requests over the Cisco SD-WAN fabric?

Answer options

• A. Auto-RP
• B. ARP
• C. OMP
• D. IGMP

Correct answer: C

Explanation

The correct answer is C, OMP, as it is specifically designed for the Cisco SD-WAN architecture to manage multicast join requests. Auto-RP (A) and IGMP (D) are used in different contexts for multicast management, while ARP (B) is used for mapping IP addresses to MAC addresses, making them unsuitable for this purpose.
