Questions 22

Given: ABC Hospital wishes to create a strong security policy as a first step in securing their 802.11 WLAN.

Before creating the WLAN security policy, what should you ensure you possess?

Options:
A.

Awareness of the exact vendor devices being installed

B.

Management support for the process

C.

End-user training manuals for the policies to be created

D.

Security policy generation software

Questions 23

As a part of a large organization’s security policy, how should a wireless security professional address the problem of rogue access points?

Options:
A.

Use a WPA2-Enterprise compliant security solution with strong mutual authentication and encryption for network access of corporate devices.

B.

Hide the SSID of all legitimate APs on the network so that intruders cannot copy this parameter on rogue APs.

C.

Conduct thorough manual facility scans with spectrum analyzers to detect rogue AP RF signatures.

D.

A trained employee should install and configure a WIPS for rogue detection and response measures.

E.

Enable port security on Ethernet switch ports with a maximum of only 3 MAC addresses on each port.

Questions 24

In what deployment scenarios would it be desirable to enable peer-to-peer traffic blocking?

Options:
A.

In home networks in which file and printer sharing is enabled

B.

At public hot-spots in which many clients use diverse applications

C.

In corporate Voice over Wi-Fi networks with push-to-talk multicast capabilities

D.

In university environments using multicast video training sourced from professor’s laptops

Questions 25

You perform a protocol capture using Wireshark and a compatible 802.11 adapter in Linux. When viewing the capture, you see an auth req frame and an auth rsp frame. Then you see an assoc req frame and an assoc rsp frame. Shortly after, you see DHCP communications and then ISAKMP protocol packets. What security solution is represented?

Options:
A.

802.1X/EAP-TTLS

B.

Open 802.11 authentication with IPSec

C.

802.1X/PEAPv0/MS-CHAPv2

D.

WPA2-Personal with AES-CCMP

E.

EAP-MD5

Questions 26

Given: In a security penetration exercise, a WLAN consultant obtains the WEP key of XYZ Corporation’s wireless network. Demonstrating the vulnerabilities of using WEP, the consultant uses a laptop running a software AP in an attempt to hijack the authorized user’s connections. XYZ’s legacy network is using 802.11n APs with 802.11b, 11g, and 11n client devices.

With this setup, how can the consultant cause all of the authorized clients to establish Layer 2 connectivity with the software access point?

Options:
A.

All WLAN clients will reassociate to the consultant’s software AP if the consultant’s software AP provides the same SSID on any channel with a 10 dB SNR improvement over the authorized AP.

B.

A higher SSID priority value configured in the Beacon frames of the consultant’s software AP will take priority over the SSID in the authorized AP, causing the clients to reassociate.

C.

When the RF signal between the clients and the authorized AP is temporarily disrupted and the consultant’s software AP is using the same SSID on a different channel than the authorized AP, the clients will reassociate to the software AP.

D.

If the consultant’s software AP broadcasts Beacon frames that advertise 802.11g data rates that are faster rates than XYZ’s current 802.11b data rates, all WLAN clients will reassociate to the faster AP.

Questions 27

What 802.11 WLAN security problem is directly addressed by mutual authentication?

Options:
A.

Wireless hijacking attacks

B.

Weak password policies

C.

MAC spoofing

D.

Disassociation attacks

E.

Offline dictionary attacks

F.

Weak Initialization Vectors
