Back 5

Bridge

Front 6

what is the primary funtion of a bridge

Back 6

keep traffic separated on either side of the bridge THEREFORE breaking up collsion domains

Front 7

Bridges use _________ to make forwarding decision and are considered what layer device

Back 7

Mac Addresses - layer 2

Front 8

Are bridges software or hardware based

Back 8

software

Front 9

connects multiple segments of a network together like a hub

Back 9

switches

Front 10

2 differences between switches and hubs

Back 10

1. switches regongize frames and pay attention to the source and destinaton MAC address of incoming frames as well as the port oon which it was received.

2. in a switch each port is its own collision domain.

Front 11

is a network device used to connect many, network segments together, combinding them into an internetwork

Front 14

do switches have IP addresses

Back 14

no

Front 15

2 incidents when a NIC can get an error

Firewall

Front 18

how many network connections will a firewall have

Back 18

2: one to the internet (public) and one to he network (private side)

Front 19

is a hub that accepts wireless clients via an analog wireless sgnal

Back 19

Access point

Front 20

what is the first line of defense for an internet connected network

Back 20

firewall

Front 21

Wireless range exenders should be placed with what percentage of overlap

Back 21

15 percent

Front 22

wire and wireless enviornments use what to arbitrate access to the medium to help prevent collisions or at he least to recover from them when they occur

Back 22

contention method

DHCP

Front 29

manually assigning IP addresses

Back 29

Static IP addressing

Front 30

IP addresses that are off limits are called what

Back 30

IP exclusions

Front 31

what layer does DHCP work at

Back 31

Application layer

Front 32

IPAM

Back 32

IP address managment

Front 33

______ tools are software products that integrate the managment of DHCP and DNS

Back 33

IPAM

Front 34

what is IPAM used for

Back 34

Plan, track, and manage the IP address

Front 35

MLS

Back 35

multilayer switch

Front 36

is a computer networking device that switches on OSI layer 2 like an ordinary network switch but provides routing

Back 36

MLS (multilayer switch)

Front 37

allows you to send incoming packets to multiple machines hidden behind 1 IP address

Back 37

Load Balancer

Front 38

FQDN

Back 38

fully qualified domain name: consists of a hostname and a domain name

Front 39

the process of finding the IP address for any given hostname is know as

Back 39

name resolution

Front 40

what other records are found on DNS servers

Back 40

mail exchanger (MX)

Front 41

is a type of server that handles its client-machine requests by forwarding them on to other servers while allowing granular control over the traffic between the local LAN and the Internet.

Back 41

proxy server

Front 42

what layer does a proxy server operate at

Back 42

application

Front 43

2 types of proxy servers

Back 43

web proxy server - caching proxy server

Front 44

used to create a web cache. remebers sites you went to and recalls your personal info

Back 44

web proxy server

Front 45

speeds up the networks servce request by recovering ifo from a clients earlier request. Keeps local copies of resources.

Back 45

cashing proxy server

Front 46

Next Generation Firewall

is application aware

Front 47

5 things that can cause LAN traffic congestion

Back 47

1 Too many hosts in a broadcast domain

2 Broadcast storms

3 Multicasting

4 Low bandwidth

5 Adding hubs for connectivity to the network

Front 48

how do you fix a slow network

Back 48

break it up into a number of smaller networks which is called network segmentation

Front 49

you can have one broadcast domain but seperate collision domains
