Certified Network Defender (CND) — Question 70

Which of the following statements are true about an IPv6 network? Each correct answer represents a complete solution. Choose all that apply.

Answer options

• A. For interoperability, IPv4 addresses use the last 32 bits of IPv6 addresses.
• B. It increases the number of available IP addresses.
• C. It uses longer subnet masks than those used in IPv4.
• D. It provides improved authentication and security.
• E. It uses 128-bit addresses.

Correct answer: B, E, A, D

Explanation

Answer B is correct as IPv6 significantly increases the number of available IP addresses compared to IPv4. Answer E is also correct because IPv6 addresses are indeed 128 bits long. Answer A, while true, is not a primary feature of IPv6, and D, while applicable, is not as fundamental as the increase in address space and address length.
