Question 1

Which of the following is true when describing an anycast address?

Accepted Answer

Anycast addresses identify multiple interfaces, which is the same as multicast; however, the big difference is that the anycast packet is only delivered to one address, the first one it finds defined in the terms of routing distance. This address can also be called one-to-one-of-many.

Question 2

Which of the following is true when describing a link-local address?

Accepted Answer

Link-local addresses are meant for throwing together a temporary LAN for meetings or a small LAN that is not going to be routed but needs to share and access files and services locally.

Question 3

Which statement(s) about IPv6 addresses are true? Leading zeros are required. Two colons (::) are used to represent successive hexadecimal fields of zeros. Two colons (::) are used to separate fields. A single interface will have multiple IPv6 addre…

Accepted Answer

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.

Question 4

Which of the following is true when describing a unicast address?

Accepted Answer

Packets addressed to a unicast address are delivered to a single interface. For load balancing, multiple interfaces can use the same address.

Question 5

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

Accepted Answer

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.

Question 6

What multicast addresses does EIGRPv6 use?

Accepted Answer

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).

Question 7

What multicast addresses does RIPng use?

Accepted Answer

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.

Question 8

Which of the following is true when describing a unique local address?

Accepted Answer

These addresses are meant for nonrouting purposes like link-local, but they are almost globally unique so it is unlikely they will have an address overlap. Unique local addresses were designed as a replacement for site-local addresses.

Question 9

Which statement(s) about IPv4 and IPv6 addresses are true? An IPv6 address is 32 bits long, represented in hexidecimal. An IPv6 address is 128 bits long, represented in decimal. An IPv4 address is 32 bits long, represented in decimal. An IPv6 addres…

Accepted Answer

IPv4 addresses are 32 bits long and are represented in decimal format. IPv6 addresses are 128 bits long and represented in hexadecimal format.

Question 10

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

Accepted Answer

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.

Question 11

Which of the following is true when describing a global unicast address?

Accepted Answer

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

Question 12

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

Accepted Answer

To enable OSPFv3, you enable the protocol as with RIPng. The command string is ipv6 ospf area .

Question 13

What two multicast addresses does OSPFv3 use? FF02::A FF02::9 FF02::5 FF02::6

Accepted Answer

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.

Question 14

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

Accepted Answer

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.

Question 15

You want to ping the loopback address of your local host(with IPv6). What will you type?

Accepted Answer

The loopback address with IPv4 is 127.0.0.1. With IPv6, that address is ::1.
