CompTIA Network+ (N10-007) — Question 495

Which of the following IPv6 transition methods requires all network devices to support IPv4 and IPv6?

Answer options

• A. 6to4
• B. Teredo
• C. ISATAP
• D. Dual stack

Correct answer: D

Explanation

The correct answer is D, Dual stack, because it allows devices to run both IPv4 and IPv6 simultaneously, requiring support for both protocols. The other methods, such as 6to4, Teredo, and ISATAP, can function with a single stack and do not mandate universal support for both protocols on all devices.
