JNCIS-SP: Juniper Networks Certified Specialist – Service Provider Routing (2022) — Question 42

The IPv6 Neighbor Discovery Protocol (NDP) performs the same function as which two IPv4 protocols? (Choose two.)

Answer options

• A. ICMP
• B. ARP
• C. DNS
• D. DHCP

Correct answer: A, B

Explanation

The correct answers are A and B because the IPv6 Neighbor Discovery Protocol (NDP) is responsible for functions that are handled by ICMP and ARP in IPv4, such as address resolution and neighbor discovery. DNS and DHCP, while important in their own right, serve different purposes related to domain name resolution and dynamic IP address allocation, respectively.
