Your company has a main office and two branch offices. The offices connect to each other by using a
WAN link.
In the main office, you have a server named Server1 that runs Windows Server 2012 R2.
Server1 is configured to use an IPv4 address only.
You need to assign an IPv6 address to Server1. The IP address must be private and routable.
Which IPv6 address should you assign to Server1?

A.
fe80:ab32:145c::32cc:401b

B.
ff00:3fff:65df:145c:dca8::82a4

C.
2001:ab32:145c::32cc:401b

D.
fd00:ab32:14:ad88:ac:58:abc2:4

Explanation:
Unique local addresses are IPv6 addresses that are private to an organization in the same way that
private addresses–such as 10.x.x.x, 192.168.x.x, or 172.16.0.0 172.31.255.255–can be used on an
IPv4 network.
Unique local addresses, therefore, are not routable on the IPv6 Internet in the same way that an
address like 10.20.100.55 is not routable on the IPv4 Internet. A unique local address is always
structured as follows:
The first 8 bits are always 11111101 in binary format. This means that a unique local address always
begins with FD and has a prefix identifier of FD00::/8.
