5. Which statement is true of a comparison between WP A and WP A2? (Source: Understanding WLAN Security)

WPA uses pre-shared keys, while WPA 2 uses PSK.

WPA uses EAP authentication, while WPA 2 uses 802.IIX.

WPA uses personal mode, while WPA 2 uses enterprise mode.

WPA uses TKIP/MIC encryption, while WPA 2 uses AES-CCMP encryption.

6. Which three are the steps to secure a WLAN? (Choose three.) (Source: Understanding WLAN Security)

Encryption for providing privacy and confidentiality

Authentication to ensure that legitimate clients and users access the network via trusted access points

Controls to transmit power to limit the access point access range to the property boundaries of the parent organization

Protection from security risks and availability with intrusion detection and intrusion protection systems for WLANs

Submit

7. What is a rogue access point? (Source: Understanding WLAN Security) A)

An access point that has an open WEP key

An access point that is broadcasting its SSID

An unsecured access point that has been placed on a WLAN

An access point that has had a hardware failure that causes it to endlessly broadcast its SSID

8. When you are implementing extended service areas, how much overlap is suggested? (Source: Implementing a WLAN)

5 to 10 percent

10 - 15 percent

15 - 20 percent

25 - 30 percent

9. When implementing a WLAN, when should you use WEP? (Source: Implementing a WLAN)

Only if there is an AAA server available

When you need the increased security ofWEP

When you are planning to enable 802.llx authentication

Only If the hardware equipment does not support WPA

13. Which statement is true about the Wi-Fi Alliance? (Source: Exploring Wireless Networking)

It is a global standards organization that controls the compatibility of Wi-Fi products.

It operates only in the United States and ensures the compatibility ofWi-Fi products

It is a global, nonprofit industry trade association devoted to promoting the growth and acceptance of wireless LAN s.

It is a global, nonprofit industry trade association devoted to promoting the installation of wireless LANs in retail locations.

14. Which three are the unlicensed bands used by WLANs? (Choose three.) (Source: Exploring Wireless Networking)

2.4-MHz band

900- MHz band

2.4-GHz band

5-GHz band

900-GHz band

Submit

15. What allows a client to communicate while moving? (Source: Implementing a WLAN)

The ability to shift data rates ,

The ability to vary transmit levels

The ability to match the transmit level to the receive level

The ability to perform error correction as the signal level changes

16. What factor determines which access point a client will associate with? (Source: Understanding WLAN Security

The access point with the lowest ssm

The access point with the highest ssm

The access point whose SSID is received first

The access point that is received with the strongest signal

17. Which three are basic wireless access point parameters? (Choose three.) (Source: Implementing a WLAN)

SSID

Authentication

Data exchange rates

Transmit band selection

RF Channel with optional power

Submit

18. When using 802.IX, how is the client authenticated? (Source: Understanding WLAN Security)

The client is authenticated against a local database stored on the access point.

The access point forwards all network traffic to the server where it is either authenticated or blocked

The access point encapsulates any 802.1 X traffic bound for the authentication server and sends it to the server
