LPIC-1 Exam 102 v5 (Linux Administrator) — Question 66

Which of the following is true about IPv6?

Answer options

• A. IPv6 no longer supports broadcast addresses.
• B. With IPv6, the TCP port numbers of most services have changed.
• C. IPv4 addresses can be used without any change with IPv6.
• D. IPv6 no longer supports multicast addresses.
• E. For IPv6, UDP and TCP have been replaced by the Rapid Transmission Protocol RTP.

Correct answer: A

Explanation

The correct answer is A because IPv6 eliminates the use of broadcast addresses, opting for multicast and anycast instead. Option B is incorrect as TCP port numbers remain the same for services in both IPv4 and IPv6. Option C is false because IPv4 addresses require translation to be used in an IPv6 environment. Option D is also incorrect since IPv6 does support multicast addresses. Lastly, option E is wrong as UDP and TCP are still valid transport protocols in IPv6.
