IPv6 - Networking MCQ Questions and answers

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.

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.

To enable OSPFv3, 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

4.
What multicast addresses does RIPng use?

A. FF02::A

B. FF02::9

C. FF02::5

D. FF02::6

Answer & Solution Discuss in Board Save for Later

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.

A. 1 and 3

B. 2 and 4

C. 1, 3 and 4

D. All of the above

Answer & Solution Discuss in Board Save for Later

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.

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

Answer & Solution Discuss in Board Save for Later

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?

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 & 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

A. 2 only

B. 3 only

C. 1 and 3

D. 3 and 4

Answer & Solution Discuss in Board Save for Later

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?

A. FF02::A

B. FF02::9

C. FF02::5

D. FF02::6

Answer & Solution Discuss in Board Save for Later

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

A. 1, 3 and 5

B. 3, 4 and 5

C. 1 and 3

D. 5 only

Answer & Solution Discuss in Board Save for Later

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.
