Implementing Cisco Data Center Infrastructure (DCII, legacy) — Question 25

Which technology is required in the underlay to facilitate remote VTEP discovery?

Answer options

• A. multicast
• B. VXLAN
• C. OSPF
• D. BGP

Correct answer: A

Explanation

Multicast is essential for remote VTEP discovery as it allows the efficient transmission of discovery messages to multiple destinations simultaneously. VXLAN, OSPF, and BGP serve different purposes, such as encapsulation, routing, and path selection, but they do not directly facilitate the discovery of VTEPs.
