QAssuming Ethernet, what type of cable is this?

ACrossover

QWhat type of cable is this?

ACoaxial

QWhat are the most common causes of signal degradation?

A• Improper Termination• Low quality cable or connectors• Cable Length exceeding standard

QWhat is the difference between Symmetrical and Asymmetrical?

AS- is even up and downA- is typically slower up and faster down

QWhat type of cable is this?

AFiber Optic

QWhat is the name of the connection point in which user equipment connects with ISP equipment?

APOP (Point of Presence)

QAssuming Ethernet, what type of cable is this?

AStraight Through

QWhat is the Internet?

AA network of networks spread all over the world.

QWhat is a DSLAM used for?

AA DSL Access Multiplexer is the device used by an ISP to accept connections from a consumer’s DSL modem.

QWhy is cable management important?

A• Presents a neat and organized

system• Aids in the isolation of cabling

problems• Protects cables from physical

damage

QWhat type of cable is this?

AUTP – Unshielded Twisted Pair

QJust like the high speed connections between switches in a LAN, what are the high speed connections on the Internet called?

AInternet Backbone connections.

QWhat type of Ethernet cable should be used in an environment where EMI is an issue?

ASTP – Shielded Twisted Pair

QWhat type of cable is this?

ASTP – Shielded Twisted Pair

QWhat type of Ethernet cable should be used indoors when EMI is not a concern?

AUTP – Unshielded Twisted Pair

QWhat term is used to describe how a packet travels across a router as it is sent on to its destination?

AHop(s)

QIf someone wanted to test the network path(s) to a specific destination, which Windows command would you use?

AMost likely you would use “tracert” which allows path specific information. One could also use the “ping” command but the result would have less path information.

QWhat are the two types of fiber optic cable?

ASingle Mode and Multimode

QAssuming Ethernet, what type of cable is this?

AStraight Through

QWhy use patch panels?

APatch panels allow for quick rearrangements of network connections should a failure occur or change become necessary.
