True or False? A home router typically only provides wired access to the network. You have to buy a separate device for wireless access.

• True

• False

Answer explanation

The correct answer is false. Typically a home network uses an integrated router equipped with both wired and wireless capabilities

Which of the following is used to connect a wired device to the internal switch of the home router?

• Ethernet Port

• Internet Port

True or false? Wi-Fi, Bluetooth, and cordless phones all use the same frequency ranges.

• True

• False

Answer explanation

The correct answer is false. Wi-Fi uses two different frequency ranges: 2.4 GHz and 5 GHz. Bluetooth also uses the 2.4 GHz frequency range. However, cordless phones operate at a lower ~900 MHz frequency range.

Which wired network technology has an inner wire surrounded by a tubular insulating layer, that is then surrounded by a tubular conducting shield.

• Category 5 cable

• Coaxial Cable

• Fibre-optic cable

Answer explanation

Coaxial cable has an inner wire surrounded by a tubular insulating layer, that is then surrounded by a tubular conducting shield.

Which organization is responsible for testing wireless LAN devices?

• IEEE

• Wi-Fi Alliance

• IETF

• TIA/EIA

Answer explanation

The Wi-Fi Alliance is responsible for testing wireless LAN devices from different manufacturers.

What is used to identify a specific wireless network?

• the Service Set Identifier (SSID)

• the network address

• the IP address of the router

• the network mode

What is created when you divide up the available radio frequency spectrum?

• Network

• SSID

• Channel

• Medium

Answer explanation

 

Channels are created by dividing up the available RF spectrum. Each channel is capable of carrying a different conversation

What is the method used to create a reservation on the channel for a specific conversation between devices?

• CSMA/CA

• CTS

• SSID

• ACK

Answer explanation

Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is the method used on wireless networks to create a reservation on the channel for a specific conversation between devices.
