The Neighbor Discovery Protocol (NDP), or simply Neighbor Discovery (ND), is a protocol of the Internet protocol suite used with Internet Protocol Version 6 (IPv6). It operates at the link layer of the Internet model, and is responsible for gathering various information required for network communication, including the configuration of local connections and the domain name servers and gateways.

Q

The provider-owned prefix falls within the 0000::/48 to FFFF::/48 range.

A

False

17
Q

With _____ addressing, devices use the common address that is closest to them based on the routing protocol metric. The next closest address is then used in the event that the primary address is no longer reachable.

A

Anycast

18
Q

In IPv6, ______ autoconfiguration allows hosts to configure their Unicast IPv6 addresses by themselves based on prefix advertisements from routers on the local network segment.

A

stateless

19
Q

An IPv6 prefix does not have to be enabled on the interface in order for a Link-Local address to be created dynamically.

A

True

20
Q

Unlike in IPv4, IPv6 views ICMPv6 as an lower-layer protocol, such as TCP, for example, which means that ICMPv6 is placed before all possible extension headers in the IPv6 packet T/F

A

False

21
Q

You are using network address 10.0.0.0 and need to apply a subnet mask so you can generate 256 subnets but no more. Which subnet mask do you apply?

A

/16

22
Q

You have been allocated network 10.10.0.0/16 and need to create 120 point-to-point subnets with very little wastage of subnets. Which mask do you apply?

A

/23

23
Q

Which address will you advertise to summarize the below networks?
172.16.8.0
172.16.9.0
172.16.10.0

172.16.12.0
172.16.13.0
172.16.14.0
172.16.15.0

A

172.16.8.0 255.255.248.0

24
Q

You have network address 192.168.1.0. Which subnet mask will you apply to give you 8 subnets but no more?

A

/27

25
Q

You can debug FTP traffic with the _____ command.

A

debug ip ftp

26
Q

TFTP provides a connection oriented transfer by using UDP port 69.

A

False (TFTP is not connection oriented)

27
Q

You enter the below command. Which command will be next?
RouterA#copy tftp flash:

A

Address or name of remote host []?

28
Q

ICMP is a requirement for any vendor who wishes to use IP on their network.

A

True

29
Q

The Multicast addresses used in IPv6 are derived from the _____ IPv6 prefix.

A

FF00::/8

30
Q

IPv6 Loopback addresses use the prefix?

A

::1

31
Q

Learning card - A Solicited-Node multicast address is:

A

An IPv6 multicast address used by the Neighbor Discovery Protocol to determine the link layer address associated with a given IPv6 address,
which is also used to check if an address is already being used by the local-link or not, through a process called DAD (Duplicate Address Detection).
The Solicited-Node multicast addresses are generated from the host’s IPv6 unicast or anycast address, and each interface must have a Solicited-Node multicast address associated with it.
A Solicited-Node address is created by taking the least-significant 24 bits of a unicast or anycast address and appending them to the prefix ff02::1:ff 00:0/104.
Example: Assume a host with a unicast/anycast IPv6 address of fe80::2aa:ff:fe28:9c5a. Its Solicited-Node multicast address will be ff02::1:ff28:9c5a.
