CCNA Routing and Switching (legacy) — Question 75

Which protocol does ipv6 use to discover other ipv6 nodes on the same segment?

Answer options

• A. CLNS
• B. TCPv6
• C. NHRP
• D. NDP
• E. ARP

Correct answer: D

Explanation

NDP (Neighbor Discovery Protocol) is the correct answer because it is specifically designed for IPv6 to discover other nodes on the same local network. The other options, such as ARP, are associated with IPv4 and do not apply to IPv6, while CLNS, TCPv6, and NHRP serve different purposes unrelated to IPv6 node discovery.
