WLAN Security and Configuration Fundamentals

City Center Hospital mandates the use of encrypted connections for employee mobile devices accessing the hospital's wireless network. What is the primary benefit of this policy?

• to verify that only authorized hospital staff can access the network

• to protect sensitive data from being exposed if transmissions are intercepted

• to stop malware on mobile devices from spreading to the network

• to prevent external denial of service attacks on the hospital's systems

Which method can an administrator implement to restrict access to a wireless network for specific devices?

• port forwarding

• MAC filtering

• VPN tunneling

• SSID broadcasting

Which of the following is a consequence of hiding the SSID on a wireless network?

• Wireless devices must be configured with the SSID to connect.

• SSID hiding guarantees complete network security.

• SSID hiding increases the network speed.

• All devices can connect automatically without knowing the SSID.

Which discovery mode causes an access point to send the highest number of probe responses on a wireless network?

• mixed mode

• active mode

• passive mode

• open mode

At a university, students can join the campus Wi-Fi without entering any credentials. What type of authentication is being used by the access point?

• passive

• shared-key

• open

• network

A visitor sets up a personal hotspot in the office, allowing others to connect to the corporate network without authorization. What type of security risk does this scenario represent?

• cracking

• spoofing

• rogue access point

• denial of service

Why might a company restrict the use of personal wireless devices near the cafeteria's microwave ovens?

• To prevent unauthorized network access

• To reduce accidental wireless signal disruption

• To avoid data interception

• To stop the use of rogue devices

Which wireless security protocol uses a centralized authentication server for user verification?

• WPA2 Personal

• WPA2 Enterprise

• WEP

• WPA Personal

Which two functions are commonly integrated into a wireless router used in residential or small office environments? (Choose two.)

• firewall

• VPN concentrator

• Ethernet switch

• access point

• proxy server

Which wireless encryption method is the most secure?

• WPA

• WEP

• WPA2 with TKIP

• WPA2 with AES
