Flashcards in Network+ Chapter 7 Deck (25):
1

What is a bit?

CH 7 pg 205

A bit is one binary digit, either a 1 or a 0.

2

A______ is 7 or 8 bits, depending on whether parity is used.
CH 7 pg 205

byte

3

An __________, made up of 8 bits, is just an ordinary 8-bit binary number.

CH 7 pg 206

Octet

4

True or False the terms byte and octet are completely interchangeable, and they are typically displayed in decimal up to 255.

CH 7 pg 206

True

5

This is the designation used in routing to send packets to a remote network— for example, 10.0.0.0, 172.16.0.0, and 192.168.10.0.
CH 7 pg 206

Network Address

6

The _____________ is used by applications and hosts to send information to all hosts on a network.
CH 7 pg 206

broadcast address

7

True or False The 32-bit IP address is known as a structured, or hierarchical, address as opposed to a flat, or nonhierarchical, address.

CH 7 pg 206

True

8

What are class D and E networks used for?

CH 7 pg 211

Class D (224– 239) is used for multicast addresses and Class E (240– 255) for scientific purposes.

9

What is the multicast broadcast range? CH 7 pg 211

multicast range is from 224.0.0.0 through 239.255.255.255.

10

Packets addressed to a unicast address are delivered to a single interface, same as in IPv4. For load balancing, multiple interfaces can use the same address.
CH 7 pg 219

Unicast

11

These are your typical publicly routable addresses, and they're used the same way globally unique addresses are in IPv4. CH 7 pg 219

Global Unicast Addresses

12

Whats the difference between DHCPv4 and DHCPv6?
CH 7 pg 223

DHCPv6 supports version IPv6

13

What is 6to4 Tunneling? CH 7 pg 224

.

6to4 tunneling is really useful for carrying IPv6 packets over a network that's still running IPv4.

14

A___________address is assigned to a single interface, and this term is used in both IPv4 and IPv6 to describe your host interface IP address.

ch 7 pg 215

Unicast Address

15

An___________ is a numeric identifier assigned to each machine on an IP network. It designates the specific location of a device on the network.

IP Address

16

address is used by applications and hosts to send information to all hosts on a network. Examples include 255.255.255.255, which designates all networks and all hosts; 172.16.255.255, which specifies all subnets and hosts on network 172.16.0.0; and 10.255.255.255, which broadcasts to all subnets and hosts on network 10.0.0.0.
ch 7 pg 206

broadcast address

17

In a ________ address, the first byte is assigned to the network address, and the three remaining bytes are used for the host addresses. The_________network format is as follows: network.host.host.host

ch 7 pg 208

Class A network

18

In a ______network address, the first 2 bytes are assigned to the network address and the remaining 2 bytes are used for host addresses. The format is as follows: network.network.host.host
ch 7 pg 209

Class B Network

19

What is the format of a Class C Network?

network.network.network.host or 255.255.255.0

20

is assigned to, and uniquely identifies, each machine on a network. ch 7 pg 207

host address

21

also called the network number— uniquely identifies each network. ch 7 pg 207

network address

22

The crux of ________ is that it enables multiple recipients to receive messages without flooding the messages to all hosts on a broadcast domain. However, this is not the default behavior— it's what we can do with multicasting if it's configured correctly!

ch 7 pg 214

Multicast

23

___________broadcasts are also known as hardware broadcasts.they only go out on a LAN, and they don't go past the LAN boundary (router).
ch 7 pg 214

Layer 2

24

What are three of the primary transition strategies available to us.

ch 7 pg 223
.

Dual Stacking
6to4 tunneling
Teredo

25

is a transition technology that gives full IPv6 connectivity for IPv6-capable hosts that are on the IPv4 Internet but have no native connection to an IPv6 network.

ch 7 pg 224
