You are using a utility that takes input and generates random output. For example, you can provide the input of a known word as a secret word and then also provide another known word as salt input. When you process the input it generates a secret code which is a combination of letters and numbers with case sensitivity. For what is the described utility used? (Choose 3)

What is the purpose of the Pairwise Transient Key (PTK) in IEEE 802.11 Authentication and Key Management?

You are using a protocol analyzer for random checks of activity on the WLAN. In the process, you notice two different EAP authentication processes. One process (STA1) used seven EAP frames (excluding ACK frames) before the 4-way handshake and the other (STA2) used 11 EAP frames (excluding ACK frames) before the 4-way handshake.

Which statement explains why the frame exchange from one STA required more frames than the frame exchange from another STA when both authentications were successful? (Choose the single most probable answer given a stable WLAN.)

While seeking the source of interference on channel 11 in your 802.11n WLAN running within 2.4 GHz, you notice a signal in the spectrum analyzer real time FFT display. The signal is characterized with the greatest strength utilizing only 1-2 megahertz of bandwidth and it does not use significantly more bandwidth until it has weakened by roughly 20 dB. At approximately -70 dB, it spreads across as much as 35 megahertz of bandwidth.

What kind of signal is described?

Given: ABC Company has recently installed a WLAN controller and configured it to support WPA2-Enterprise security. The administrator has configured a security profile on the WLAN controller for each group within the company (Marketing, Sales, and Engineering).

How are authenticated users assigned to groups so that they receive the correct security profile within the WLAN controller?

Given: ABC Corporation’s 802.11 WLAN is comprised of a redundant WLAN controller pair (N+1) and 30 access points implemented in 2004. ABC implemented WEP encryption with IPSec VPN technology to secure their wireless communication because it was the strongest security solution available at the time it was implemented. IT management has decided to upgrade the WLAN infrastructure and implement Voice over Wi-Fi and is concerned with security because most Voice over Wi-Fi phones do not support IPSec.

As the wireless network administrator, what new security solution would be best for protecting ABC’s data?

A single AP is configured with three separate WLAN profiles, as follows:

1. SSID: ABCData – BSSID: 00:11:22:00:1F:C3 – VLAN 10 – Security: PEAPv0/EAP-MSCHAPv2 with AES-CCMP – 3 current clients

2. SSID: ABCVoice – BSSID: 00:11:22:00:1F:C4 – VLAN 60 – Security: WPA2-Personal with AES-CCMP – 2 current clients

3. SSID: Guest – BSSID: 00:11:22:00:1F:C5 – VLAN 90 – Security: Open with captive portal authentication – 3 current clients

Three STAs are connected to ABCData. Three STAs are connected to Guest. Two STAs are connected to ABCVoice.

How many unique GTKs and PTKs are currently in place in this scenario?

What TKIP feature was introduced to counter the weak integrity check algorithm used in WEP?

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

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?
