Your network contains an Active Directory domain named contoso.com. The domain
contains a server named Server1 that runs Windows Server 2012 R2 and has the DHCP
Server server role installed.
You need to create an IPv6 scope on Server1. The scope must use an address space that is
reserved for private networks. The addresses must be routable.
Which IPV6 scope prefix should you use?
A.
2001:123:4567:890A::
B.
FE80:123:4567::
C.
FF00:123:4567:890A::
D.
FD00:123:4567::
Answer = A

2001:: is the prefix for global unicast addresses not for private routable addresses.
D is correct.

bobsmith u probably forgotten ur 70-410 class
Correct Answer is D.
http://en.wikipedia.org/wiki/Unique_local_address
Prefixes in the fd00::/8 range have similar properties as those of the IPv4 private address ranges.
http://www.simpledns.com/private-ipv6.aspx
IPv6 private routable IP addresses begin with FD or FC > from the CCNA and probably from the 410, but I took my CCNA more recently and definitely remember that (I’m also a network engineer)
Oh boy. The v6 equivalent to a rfc1918 address is called ULA.
Here you go

The answer D is right
Why not FF00:123:4567:890A:: ?
Sorry i didn’t read the article http://www.subnetting-secrets.com/members/ipv6/different-ipv6-address-types.html. FF is for multicast-
I am confused , in the question they are asking for IPv6 which is both used for private network and routable , what I know is that FD00:: is used for private networks but it’s NOT routable !! and 2001:: is routable IP but it’s not used for private networks .. can someone explain for me why the answer is D ??
The difference here is between Link-Local (FE80) and Unique Local (FD00).
Routers will drop FE80 packets, they are only used on a local segment.
Internal routers will route FD00, but IPSs should be dropping them. The are route-able just not on the public internet.
“Unique local addresses are available for use in private networks, e.g. inside a single site or organization or spanning a limited number of sites or organizations. They are not routable in the global IPv6 Internet.”
“Link-local addresses are usually not guaranteed to be unique beyond a single network segment. Routers therefore do not forward packets with link-local addresses.”
thanks mslover for your explanation , its Cristal clear
A+ explanation sir.
