Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
IPv4-IPv6 translation (NAT64-like)
MAP-T (Mapping of Address and Port using Translation) uses IPv4-IPv6 translation (stateless NAT64-like) at the customer edge, not encapsulation.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
MPLS label switching
Why it's wrong here
MPLS is not specific to MAP-T.

Why it's wrong here
MAP-E uses encapsulation; MAP-T uses translation.
- ✗
IPv6 in IPv4 encapsulation
Why it's wrong here
That is 6rd or 6PE.
