Which one of the following describes the correct hierarchy of 802.1X authentication key derivation?

• A.After successful EAP authentication, the RADIUS server generates a PMK. A separate key, the MSK, is derived from the AAA key and is hashed with the PMK to create the PTK and GTK.
• B.The PMK is generated from a successful mutual EAP authentication. When mutual authentication is not used, an MSK is created. Either of these two keys may be used to derive the temporal data encryption keys during the 4-way handshake.
• C.The MSK is generated from the 802.1X/EAP authentication. The PMK is derived from the MSK. The PTK is derived from the PMK, and the keys used for actual data encryption are a part of the PTK.
• D.If passphrase-based client authentication is used by the EAP type, the PMK is mapped directly from the user's passphrase. The PMK is then used during the 4-way handshake to create data encryption keys.

Given: You have implemented strong authentication and encryption mechanisms for your enterprise 802.11 WLAN using 802.1X/EAP with AES-CCMP.
For users connecting within the headquarters office, what other security solution will provide continuous monitoring of both clients and APs with 802.11-specific tracking?

• A.IPSec VPN client and server software
• B.WLAN endpoint agent software
• C.Wireless intrusion prevention system
• D.RADIUS proxy server
• E.Internet firewall software

You are implementing a wireless LAN that will be used by point-of-sale (PoS) systems in a retail environment. Thirteen PoS computers will be installed. To what industry requirement should you ensure you adhere?

• A.PCI-DSS
• B.Directive 8500.01
• C.HIPAA
• D.ISA99

Given: You are the WLAN administrator in your organization and you are required to monitor the network and ensure all active WLANs are providing RSNs. You have a laptop protocol analyzer configured.
In what frame could you see the existence or non-existence of proper RSN configuration parameters for each BSS through the RSN IE?

• A.Data frames
• B.CTS
• C.Beacon
• D.RTS
• E.Probe request

For a WIPS system to identify the location of a rogue WLAN device using location patterning (RF fingerprinting), what must be done as part of the WIPS installation?

• A.At least six antennas must be installed in each sensor.
• B.A location chipset (GPS) must be installed with it.
• C.The RF environment must be sampled during an RF calibration process.
• D.All WIPS sensors must be installed as dual-purpose (AP/sensor) devices.
