To enable RIPng, which of the following would you use?
A.     Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
B.     Router1(config-if)# ipv6 router rip 1
C.     Router1(config)# ipv6 router eigrp 10
D.     Router1(config-rtr)# no shutdown
E.     Router1(config-if)# ipv6 eigrp 10
Answer & Explanation

Answer: Option B

Explanation:

It’s pretty simple to enable RIPng for IPv6. You configure it right on the interface where you want RIP to run with the ipv6 router rip number command.

Which of the following is true when describing a global unicast address?
A.     Packets addressed to a unicast address are delivered to a single interface.
B.     These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
C.     These are like private addresses in IPv4 in that they are not meant to be routed.
D.     These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
Answer & Explanation

Answer: Option B

Explanation:

Unlike unicast addresses, global unicast addresses are meant to be routed.

What two multicast addresses does OSPFv3 use?

FF02::A
FF02::9
FF02::5
FF02::6

A.     2 only
B.     3 only
C.     1 and 3
D.     3 and 4
Answer & Explanation

Answer: Option D

Explanation:

Adjacencies and next-hop attributes now use link-local addresses, and OSPFv3 still uses multicast traffic to send its updates and acknowledgments with the addresses FF02::5 for OSPF routers and FF02::6 for OSPF designated routers. These are the replacements for 224.0.0.5 and 224.0.0.6, respectively.

What multicast addresses does EIGRPv6 use?
A.     FF02::A
B.     FF02::9
C.     FF02::5
D.     FF02::6
Answer & Explanation

Answer: Option A

Explanation:

EIGRPv6’s multicast address stayed very near the same. In IPv4 it was 224.0.0.10; now it is FF02::A (A=10 in hexadecimal notation).

To enable EIGRP, which of the following would you use?

Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
Router1(config-if)# ipv6 router rip 1
Router1(config)# ipv6 router eigrp 10
Router1(config-rtr)# no shutdown
Router1(config-if)# ipv6 eigrp 10

A.     1, 3 and 5
B.     3, 4 and 5
C.     1 and 3
D.     5 only
Answer & Explanation

Answer: Option B

Explanation:

Unlike RIPng and OSPFv3, you need to configure EIGRP both from global configuration mode and from interface mode, and you have to enable the command with the no shutdown command.
