CompTIA Linux+ Powered by LPI (LX0-104) — Question 13

Which of the following is true about IPv6?

Answer options

• A. With IPv6, the TCP port numbers of most services have changed.
• B. IPv6 no longer supports broadcast addresses.
• 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• E. For IPv6, UDP and TCP have been replaced by the Rapid Transmission Protocol RTP.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: B

Explanation

The correct answer is B, as IPv6 eliminates the use of broadcast addresses in favor of multicast and anycast addressing. Option A is incorrect because TCP port numbers remain the same across both protocols. Option C is false because IPv4 addresses cannot be directly used in IPv6 without changes. Options D and E are also incorrect, as IPv6 does support multicast addresses and does not replace UDP and TCP with RTP.
