IPv6

1. Which of the following is true when describing a multicast address?

A. Packets addressed to a unicast address are delivered to a single interface.
B. Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.
C. Identifies multiple interfaces and is only delivered to one address. This address can also be called one-to-one-of-many.
D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

Correct Answer: B. Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.

2. Which of the following is true when describing a 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.

Correct Answer: A. Packets addressed to a unicast address are delivered to a single interface.

3. To enable OSPFv3, which of the following would you use?

C. Router1(config)# ipv6 router eigrp 10
D. Router1(config-rtr)# no shutdown
E. Router1(config-if)# ipv6 eigrp 10
