1
Which of the following is true when describing a multicast address?
Discuss
Answer & Solution
Answer: Option B
Solution:
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.
2
Which of the following is true when describing a unicast address?
Discuss
Answer & Solution
Answer: Option A
Solution:
Packets addressed to a unicast address are delivered to a single interface. For load balancing, multiple interfaces can use the same address.
3
To enable OSPFv3, which of the following would you use?
Discuss
Answer & Solution
Answer: Option A
Solution:
To enable OSPFv3, you enable the protocol as with RIPng. The command string is ipv6 ospf area .
4
What multicast addresses does RIPng use?
Discuss
Answer & Solution
Answer: Option B
Solution:
RIPng uses the multicast IPv6 address of FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same.
5
Which statement(s) about IPv6 addresses are true?
1. Leading zeros are required.
2. Two colons (::) are used to represent successive hexadecimal fields of zeros.
3. Two colons (::) are used to separate fields.
4. A single interface will have multiple IPv6 addresses of different types.
Discuss
Answer & Solution
Answer: Option B
Solution:
In order to shorten the written length of an IPv6 address, successive fields of zeros may be replaced by double colons. In trying to shorten the address further, leading zeros may also be removed. Just as with IPv4, a single device's interface can have more than one address; with IPv6 there are more types of addresses and the same rule applies. There can be link-local, global unicast, and multicast addresses all assigned to the same interface.
6
To enable RIPng, which of the following would you use?
Discuss
Answer & Solution
Answer: Option B
Solution:
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.
7
Which of the following is true when describing a global unicast address?
Discuss
Answer & Solution
Answer: Option B
Solution:
Unlike unicast addresses, global unicast addresses are meant to be routed.
8
What two multicast addresses does OSPFv3 use?
1. FF02::A
2. FF02::9
3. FF02::5
4. FF02::6
Discuss
Answer & Solution
Answer: Option D
Solution:
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.
9
What multicast addresses does EIGRPv6 use?
Discuss
Answer & Solution
Answer: Option A
Solution:
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).
10
To enable EIGRP, which of the following would you use?
1. Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
2. Router1(config-if)# ipv6 router rip 1
3. Router1(config)# ipv6 router eigrp 10
4. Router1(config-rtr)# no shutdown
5. Router1(config-if)# ipv6 eigrp 10
Discuss
Answer & Solution
Answer: Option B
Solution:
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.
