IPv6 Addressing

1. Router R1 has an interface named Gigabit Ethernet 0/1, whose MAC address has been set
to 0200.0001.000A. Which of the following commands, added in R1’s Gigabit Ethernet
0/1 configuration mode, gives this router’s G0/1 interface a unicast IPv6 address of
2001:1:1:1:1:200:1:A, with a /64 prefix length?
a. ipv6 address 2001:1:1:1:1:200:1:A/64
b. ipv6 address 2001:1:1:1:1:200:1:A/64 eui-64
c. ipv6 address 2001:1:1:1:1:200:1:A /64 eui-64
d. ipv6 address 2001:1:1:1:1:200:1:A /64
e. None of the other answers are correct.
2. Router R1 has an interface named Gigabit Ethernet 0/1, whose MAC address has
been set to 5055.4444.3333. This interface has been configured with the ipv6 address
2000:1:1:1::/64 eui-64 subcommand. What unicast address will this interface use?
a. 2000:1:1:1:52FF:FE55:4444:3333
b. 2000:1:1:1:5255:44FF:FE44:3333
c. 2000:1:1:1:5255:4444:33FF:FE33
d. 2000:1:1:1:200:FF:FE00:0
3. Router R1 currently supports IPv4, routing packets in and out all its interfaces. R1’s configuration
needs to be migrated to support dual-stack operation, routing both IPv4 and
IPv6. Which of the following tasks must be performed before the router can also support
routing IPv6 packets? (Choose two answers.)
a. Enable IPv6 on each interface using an ipv6 address interface subcommand.
b. Enable support for both versions with the ip versions 4 6 global command.
c. Additionally enable IPv6 routing using the ipv6 unicast-routing global command.
d. Migrate to dual-stack routing using the ip routing dual-stack global command.

4. Router R1 has an interface named Gigabit Ethernet 0/1, whose MAC address has
been set to 0200.0001.000A. The interface is then configured with the ipv6 address
2001:1:1:1:200:FF:FE01:B/64 interface subcommand; no other ipv6 address commands
are configured on the interface. Which of the following answers lists the link-local address
used on the interface?
a. FE80::FF:FE01:A
b. FE80::FF:FE01:B
c. FE80::200:FF:FE01:A
d. FE80::200:FF:FE01:B
5. Which of the following multicast addresses is defined as the address for sending packets
to only the IPv6 routers on the local link?
a. FF02::1
b. FF02::2
c. FF02::5
d. FF02::A
6. Router R1 has an interface named Gigabit Ethernet 0/1, whose MAC address has been
set to 0200.0001.000A. Which of the following commands, added in R1’s Gigabit
Ethernet 0/1 configuration mode, results in R1 using a solicited node multicast address of
FF02::1:FF00:A?
a. ipv6 address 2001:1:1:1:1:200:1:A/64
b. ipv6 address 2001:1:1:1::/64 eui-64
c. ipv6 address 2001:1:1:1::A/64
d. None of the other answers results in R1 using that multicast address.
