22
Q

Address is delivered to only one of the interfaces identified by that address

A

Anycast

The “nearest” one, according to the routing protocols’ measure of distance

23
Q

This type of address is used for generic IPv6 communication

A

Global Unicast Addresses

24
Q

How are the bits divided within the Global Unicast Addresses?

A

First 48 bits are used to identify this service provider (ISP)
The next 16 bits are used for the subnet
The last 64 bits are used as the host interface identified

25
Q

True/False?

A host hasconnectivity beyond the local link unless it locates a default router router and obtain it’s global address unique to the network.

A

False

A host does NOT have connectivity

26
Q

Type of address that had a scope that is limited to the link and is automatically configured with the interface ID

A

Link-Local addresses

27
Q

Network is prefixed with FE80:: and the 2nd 64 bits is tied to the interface ID (Physical Address)

A

Link-Local addresses

28
Q

Used in Stainless Auto configuration and for creating local network without the presence of a router

A

Link-Local addresses

29
Q

Type of address that has a scope limited to the site and contain the inside topology of the site with the subnet Id of the site.

A

Site-Local addresses

30
Q

Network is prefixed with FEC0::/10 and bits 48 - 64 are set to the subnet Id if the site.

A

Site-Local addresses

31
Q

Addresses are routable, but not to the internet.

IPv6 addresses can use private IP addresses, AND can connect to any other address within the organization.

A

Site-Local addresses

32
Q

Used as a place holder when no IPv6 address is specified an the host much obtain an address from a router or Dynamic Host Configuration Protocol (DHCPv6) server

A

Unspecified

33
Q

Identifies itself and is used for testing.

A

Loopback

34
Q

True/False

IPv4 and IPv6 are compatible with each other

A

False

IPv4 and IPv6 are not compatible because the addressing system and datagram format are different

35
Q

What is an option to make IPv4 and IPv6 compatible?

A

Use nodes with what is called ‘IPv4 compatible IPv6 address’.

Every current IPv4 address can be transformed to an IPv6 compatible address in this way. However additional hardware devices are required

36
Q

What is used to represent the addresses of IPv4 nodes as IPv6 addresses?

A

IPv4 mapped

37
Q

The first 80 bits are all kept at zeros, next 16 bits are all set to FFF, and the last 32 bits are expressed as IPv4 dotted decimal or IPv6 notation

A

IPv4 mapped

38
Q

IPv6 address is enclosed in square brackets and can be cumbersome for most users

A

URL

39
Q 
What are these features of:
New header format
Stateful
Stateless
Neighbor Discovery(ND)
Built-in security
Better support for quality of service (QoS)
Mobile IP
Extensibility
A

IPv6 Features

40
Q

Achieved by moving both nonessential fields an option fields to extension headers that are placed after the IPv6 header

A

New Header Format

41
Q

IP address is one that is automatically configured by router discovery.

A

Stateless

42
Q

Idea is for machines to discover information about their nearest router

A

Neighbor Discovery (ND)

43
Q

Promotes interoperability between different IPv6 implementations

A

Built-in Security

44
Q

Traffic is identified by using a Flow Label field in the header, this allows routers to identify and provide special handling for packets that belong to a flow

A

Better support for quality of service (QoS)

45
Q

What a communications protocol designed to allow mobile device users to move from one network to another while maintaining their permanent IP address

A

Mobile IP

46
Q

What is a processing location.

Can be a computer or some other device.

A

Node

47
Q

Computer that is connected to a TCP/IP network, including the internet

A

Host

48
Q

Device that forwards data packets along networks

A

Router

49
Q

Communication facility or medium over which nodes can communicate at the link later

A

Link

50
Q

Nodes attached to the same link

A

Neighbors

51
Q

Nodes attachment to a link

A

Interface

52
Q

An IP later identifier for an interface or a set of interfaces

A

Address

53
Q

An IP header plus payload

A

Packet

54
Q

Protocol stack that contains both IPv4 and IPv6

A

Dual Stack

55
Q

Are IPv4 and IPv6 compatible?

A

No.
