Network+ Chapter 7 Flashcards
What is a bit?
CH 7 pg 205
A bit is one binary digit, either a 1 or a 0.
A______ is 7 or 8 bits, depending on whether parity is used.
CH 7 pg 205
byte
An __________, made up of 8 bits, is just an ordinary 8-bit binary number.
CH 7 pg 206
Octet
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
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
The _____________ is used by applications and hosts to send information to all hosts on a network.
CH 7 pg 206
broadcast address
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
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.
What is the multicast broadcast range? CH 7 pg 211
multicast range is from 224.0.0.0 through 239.255.255.255.
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
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
Whats the difference between DHCPv4 and DHCPv6?
CH 7 pg 223
DHCPv6 supports version IPv6
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.
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
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
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
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
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
What is the format of a Class C Network?
network.network.network.host or 255.255.255.0
is assigned to, and uniquely identifies, each machine on a network. ch 7 pg 207
host address
also called the network number— uniquely identifies each network. ch 7 pg 207
network address
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
___________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
What are three of the primary transition strategies available to us.
ch 7 pg 223
.
Dual Stacking
6to4 tunneling
Teredo
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.
