With the evolution from IPv4 network to IPv6, some transitional technologies have emerged. Which of the following are common types of transitional technologies? (Multiple choice)

Question

Options

• ADual stack technology
• BTunneling technology
• CCompatible technologies
• DTranslation technology

• A
  82% (32)
• C
  18% (7)

Explanation

IPv4-to-IPv6 transition relies on three well-established mechanisms: Dual Stack (A) runs both IPv4 and IPv6 simultaneously on the same device, allowing gradual migration; Tunneling (B) encapsulates IPv6 packets inside IPv4 packets to traverse legacy infrastructure; and Translation (D) (e.g., NAT64) converts between IPv4 and IPv6 at the protocol level, enabling communication between hosts that only speak one version.

Option C ("Compatible technologies") is a distractor - while the term sounds plausible, it is not a recognized standard category of IPv6 transition mechanisms. The three canonical categories defined by IETF and referenced in networking curricula are dual stack, tunneling, and translation.

Memory tip: Think "DTT" - Dual stack, Tunneling, Translation - the three legs of the IPv6 transition stool. If you see "compatible technologies" on an exam, recognize it as a vague, non-standard term designed to trip you up.
