The answers each list a tunnel method and two consecutive IPv6 address quartets. Which
answers identify a tunneling method that relies on an IPv4 address to be embedded into an
IPv6 address, within the correct quartets listed? (Choose two.)

A.
Automatic 6to4, quartets 2 and 3

B.
Automatic 6to4, quartets 7 and 8

C.
ISATAP, quartets 2 and 3

D.
ISATAP, quartets 7 and 8

Explanation:

ISATAP uses a modified EUI-64 format, which adds the IPv4 address, in
hex, into quartets 7 and 8. Automatic 6to4 tunnels use address range 2002::/16, with
the next two quartets (second and third quartets) used to store the hex version of an
IPv4 address.
