In WPA-PSK and WPA2-PSK, the Pairwise Transient Key (PTK) is a dynamic key that is per session / per client

When using an 802.11 wireless controller solution with an 802.1x framework, which device would be considered the authenticator?

If an attacker compromises a Pairwise Transient Key (PTK) in a WPA based network, they will be able to decrypt all of the traffic on that wireless network.

Which key is used to encrypt and decrypt unicast traffic between a client station and AP in a WPA / WPA 2 implementation?

Which wireless security implementation offers this highest level of security available using today’s standards?

What three main components constitute an 802.1X/EAP framework? (Choose Three)

If an attacker compromises the shared key in a WEP based network, they will be able to decrypt all of the traffic on that wireless network.

In a WPA-PSK implementation, the pre-shared key is the same key used to encrypt and decrypt unicast traffic.

TKIP has been cracked

Which key is used to decrypt broadcast and multicast traffic in a WPA / WPA2 implementation?

Which cipher suites are available in WPA2? (Choose all that apply)

Which current wireless security standard is 802.11i compliant?

Which cipher suites are available in WPA? (Choose all that apply)

Which wireless security implementation would be the most secure option for SOHO WLAN implementation which do not have RADIUS servers available?

Which security solution may be used to segment a LAN or wireless LAN

You want to place users on different network segments once they authenticate based on the users role. Which technology will help you achieve this?

Which of the following factors indicate that a RSN is being used? (Choose Two)

Hiding the SSID provides good security for wireless networks

Which IEEE Standard defines the framework for port-based authentication?

Which encryption algorithm is used by the CCMP cipher suite?

Which encryption algorithm is used by the WEP cipher suite?

Which encryption algorithm is used by the TKIP cipher suite?

Which of the following are weaknesses of WEP?

AES has been cracked

In WPA + EAP and WPA2 + EAP, the Pairwise Transient Key (PTK) is a dynamic key that is per session / per client

Which of the following would be the most secure option for an Enterprise WLAN implementation?

An attacker is flooding your wireless service area with spoofed de-authentication frames. What type of attack is being performed?

You are running a wireless network with WPA2-PSK using AES encryption. Your pre-shared key contains words found in the English dictionary and does not follow best practices for complexity. Which attack have you left yourself open to?

Which of the following is considered a DoS attack? (Choose One)

What are some problems with rogue access points?

What is the major weakness of MAC filtering?

An attacker starts a software-based AP on his laptop. He then scans for the SSID of the AP at the coffee shop hotspot where he is located. He sets his software-based AP to the same SSID. What type of attack is he likely beginning?

Which of these attacks will not be detected by a WIDS?

Which of the following can notify the network administrator of a wide variety of wireless attacks when they are detected but cannot attempt to mitigate the attack?

An attacker wants to steal data from users on an open and unsecured hotspot at a coffee shop. Which type of attack might the attacker use?

While performing a penetration test on a WLAN, you attempt to connect to the IP address of the AP in a web browser. Your connection is denied when connecting through the WLAN. What attack method is being protected against in this scenario?

You are the network administrator for a Small Business named Pizza2Go. The single AP your organization uses is configured with WPA-PSK, and the pre-shared key is set to your company name followed by the number 7. Is this a secure implementation and why?

An attacker completes a DoS attack on your wireless network . Which security concept in the CIA security triad has been compromised?

MAC Filtering is sufficient for securing most wireless networks.

You have failed to remove the default user id and password from your wireless access point before placing it into production. Which type of attack have you left yourself very vulnerable to?

If you connect to a wireless hotspot and you do not have Windows Firewall or another third-party firewall enabled on your device, you have left yourself open to which type of attack?

A hacker convinces an IT staff member that he is an employee of the company and has the IT staff member program the company’s pre-shared key into his laptop so that he may access the corporate wireless network. This is an example of which type of attack?

If you fail to keep logs on user activity in your network environment, which AAA concept have you failed to implement?

Which of the following can notify the network administrator of a wide variety of wireless attacks when they are detected as well as respond to the attack by changing the network environment in an attempt to prevent or mitigate the attack?

A hacker cracks your WEP key and then eavesdrops on data from your wireless network. Which security concept in the CIA security triad has been compromised?

The best way to prevent Social Engineering Attacks is:

WPA2-PSK (Pre-Shared Key) with AES may be vulnerable to authentication cracking

WEP should never be used to secure a production wireless network that transmits sensitive data.
