Networking Essentials - Ch 4 Media

The two basic categories of physical cabling used in an Ethernet network.

• Fiberoptics and Ethernet
• Ethernet and Wireless
• Fiberoptics and Wireless
• Infrared and Bluetooth

The length of cable between the wall jack and a patch panel is called ?

• Vertical Cabling
• Patch Panel
• Horizontal Cabling
• Backbone Cabling

Because it uses light pulses instead of electrical signals, it is immune to interference and highly resistant to eavesdropping

• Ethernet
• Bluetooth
• IrDA
• Fiberoptics

Which of the following is not one of the main differences between the types of network cabling?

• The distance a signal can travel
• The ability to send and receive signals
• the type of signal the media can transmit
• the speed at which the signal can be sent

This type of network is often used to extend the reach of a wired LAN.

• Repeater
• Wireless
• MESH network
• Star topology

The type of network(s) susceptible to RFI?

• Wired only
• Wireless only
• Both wired and wireless
• No network is susceptible to RFI

Which of the following is not a form of electromagnetic interference, or EMI?

• rain/fog
• transformer
• fluorescent lights
• crosstalk

When a signal travels across network medium, it loses strength the further it goes.  This is called:

• electromagnetic interference
• crosstalk
• radio frequency interference
• attentuation

What are all of the connections in a network considered, including the cables and their connectors?

• telecommunications closet
• horizontal wiing
• work area

• cable plant

What is the maximum bandwidth for a network cabled using CAT5E UTP cable?

• 10 Mbps
• 16 Mbps
• 100 Mbps
• 1000 Mbps
