The answer is not provided.
Here is my reference:
Global
6to4
Link-local
Site-local

6to4 is not an IP address type but a tunneling technic to propagate the IPV6 traffic over a IPV4 network
so the correct answer should be ( in my opinion ):
global
Solicitated node
link-local
site-local
0
0
Solicited-node is not unicast but multicast address. RIPE claims that 6to4 is a type of IPv6 address:

2 seconds:
GOOGLE.COM + 2 seconds to CLICK…..come ON guys….are we Tech’s or end users?
@Ferdinando : take careful note in these Wiki.
6to4 is NOT a tunnelling technology.
“without the need to configure explicit tunnels.”
THE 6-to-4 address is not really a tunnel the way a GRE or IPSEC would be defined.
“6to4 embeds an IPv6 packet inside
the payload portion
of an IPv4 packet
with protocol type 41”
ERGO…..a unicast IPv4 packet (a correct answer above) and ….it just HAPPENS to have an ipv6 packet inside of it…..think of the movie Alien in 1979….yes…like THAT.
This is my exam-mem devise…..6to4 is a “chest burster.”
To review: 6to4 is JUST an ipv4 transit mech.
It moves IPv6 packets from ONE ipv6 pool to another ipv6 pool
….while traveling THROUGH an ipv4 ONLY lan/wan segment.
Merging the RFC reserved 2002::
with a prefix that is derived
using the EUI-64 representation
of the System (phone, router, switch, machine…what have you) MAC address.
The FAR END router recognizes the reserved 2002: Prefix
and hence provides real time conversion (ipv4->ipv6 NAT..I guess you could say)
On a personal note: I agree with Ferdinando,
that SOUNDS like a tunnel to ME too
….but cisco tac / test team will take your points away
on an exam question SOMEWHERE if you fight with them about THEIR terminology.
I am seconding Kaloyan:
6to4 IS a (very specific) unicast-address so it counts.
what INFURIATES me about this question.
….if SITE-LOCAL is correct…then HOW is “RESERVED” incorrect?
since SITE-LOCAL IS JUST a RESERVED PREFIX for a reserved address.
it WOULD seem to me…that if you take SITE-LOCAL….you HAVE TO BRING RESERVED with it.

guys…..we need to find the ONE page in the BOOK that has THIS SPECIFIC question in the “do I know this already” section and get a FIRM confirmation from Cisco Press what these idiots really want…….often the person who wrote the question was right…but the TEST CREATORS have NO IDEA what it meant…and they just typ-o when copying the content into the exam engine.
serious.
