When used as part of a WLAN authentication solution, what is the role of LDAP?
A WLAN is implemented using WPA-Personal and MAC filtering. To what common wireless network attacks is this network potentially vulnerable? (Choose 3)
What statements are true about 802.11-2012 Protected Management Frames? (Choose 2)
Given: ABC Company is implementing a secure 802.11 WLAN at their headquarters (HQ) building in New York and at each of the 10 small, remote branch offices around the United States. 802.1X/EAP is ABC's preferred security solution, where possible. All access points (at the HQ building and all branch offices) connect to a single WLAN controller located at HQ. Each branch office has only a single AP and minimal IT resources. What security best practices should be followed in this deployment scenario?
Given: AAA is an architectural framework used to provide three separate security components in a network. Listed below are three phrases that each describe one aspect of the AAA framework. Option-1 --- This AAA function is performed first and validates user identify prior to determining the network resources to which they will be granted access. Option-2 --- This function is used for monitoring and auditing purposes and includes the collection of data that identifies what a user has done while connected. Option-3 --- This function is used to designate permissions to a particular user. What answer correctly pairs the AAA component with the descriptions provided above?
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?
An attack is under way on the network. The attack is preventing users from accessing resources required for business operations, but the attacker has not gained access to any files or data. What kind of attack is described?
Given: ABC Company is deploying an IEEE 802.11-compliant wireless security solution using 802.1X/EAP authentication. According to company policy, the security solution must prevent an eavesdropper from decrypting data frames traversing a wireless connection. What security characteristics and/or components play a role in preventing data decryption? (Choose 2)
You are implementing an 802.11ac WLAN and a WIPS at the same time. You must choose between integrated and overlay WIPS solutions. Which of the following statements is true regarding integrated WIPS solutions?
In order to acquire credentials of a valid user on a public hot-spot network, what attacks may be conducted? Choose the single completely correct answer.

Given: When the CCMP cipher suite is used for protection of data frames, 16 bytes of overhead are added to the Layer 2 frame. 8 of these bytes comprise the MIC.

What purpose does the encrypted MIC play in protecting the data frame?

A.
The MIC is used as a first layer of validation to ensure that the wireless receiver does not incorrectly process corrupted signals.
Answers
A.
The MIC is used as a first layer of validation to ensure that the wireless receiver does not incorrectly process corrupted signals.
B.
