- Question
You want to ping the loopback address of your local host(with IPv6). What will you type?
Options- A. ping 127.0.0.1
- B. ping 0.0.0.0
- C. ping ::1
- D. trace 0.0.::1
- Correct Answer
- ping ::1
ExplanationThe loopback address with IPv4 is 127.0.0.1. With IPv6, that address is ::1. - 1. Which of the following is true when describing a multicast address?
Options- 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. Discuss
- 2. What two multicast addresses does OSPFv3 use?
- FF02::A
- FF02::9
- FF02::5
- FF02::6
Options- A. 2 only
- B. 3 only
- C. 1 and 3
- D. 3 and 4 Discuss
- 3. To enable OSPFv3, which of the following would you use?
Options- 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 Discuss
- 4. Which of the following is true when describing a global unicast address?
Options- 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. Discuss
- 5. To enable RIPng, which of the following would you use?
Options- 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 Discuss

Correct Answer: Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address.
Explanation:
Packets addressed to a multicast address are delivered to all interfaces identified by the multicast address, the same as in IPv4. It is also called a one-to-many address. You can always tell a multicast address in IPv6 because multicast addresses always start with
FF.
Correct Answer: 3 and 4
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.
Correct Answer: Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
Explanation:
To enable OSPFv3, you enable the protocol as with RIPng. The command string is ipv6
ospf <process-id> area <area-id>.
Correct Answer: These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
Explanation:
Unlike unicast addresses, global unicast addresses are meant to be routed.
Correct Answer: Router1(config-if)# ipv6 router rip 1
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.
