Which wireless LAN (WLAN) standards can operate in the 5 GHz frequency band?

Each correct answer represents a complete solution. Choose all that apply.

• 802.11g

• 802.11b

• 802.11a

• 802.11n

A wireless LAN (WLAN) containing only one access point (AP) is known as what type of WLAN?

• BSS

• IBSS

• SSID

• ESS

The IEEE 802.11a wireless standard has which of the following frequency band / maximum bandwidth parameters?

• 5 GHz / 54 Mbps

• 2.4 GHz / 54 Mbps

• 2.4 GHz / 11 Mbps

• 5 GHz / 11 Mbps

When extending the range for a 2.4GHz WLAN, you can use nonoverlapping channels for adjacent coverage cells. However, there should be some overlap in coverage between those cells (using nonoverlapping channels) to prevent a connection from dropping as a user roams from one coverage cell to another. What percentage of coverage overlap should you recommend for these adjacent cells?

• 15% to 20%

• 10% to 15%

• 5% to 10%

• 20% to 25%

Which of the following wireless LAN (WLAN) security threats involves mathematical algorithms that can determine a pre-shared key value?

• War driving

• Warchalking

• WEP and WPA security cracking

• Rogue access point

Which of the following are common sources of interference with a wireless LAN (WLAN)?

Each correct answer represents a complete solution. Choose all that apply.

• CB radios

• Cordless phones

• Wireless microphones

• Microwave ovens

You are configuring a wireless access point (AP). You specify a wireless standard of 802.11n operating in the 2.4 GHz band. You also select an option to make it operate in a "backward compatible" mode. Therefore, what additional 802.11 standards are supported?

Each correct answer represents a complete solution. Choose all that apply.

• 802.11ac

• 802.11g

• 802.11b

• 802.11a

What is the maximum bandwidth of an 802.11g wireless LAN (WLAN)?

• > 300 Mbps

• 54 Mbps

• 11 Mbps

• 2 Mbps

Which of the following wireless LAN (WLAN) security threats is also known as an "evil twin?"

• WEP and WPA security cracking

• Warchalking

• War driving

• Rogue access point

The IEEE 802.11g wireless standard has which of the following frequency band / maximum bandwidth parameters?
