The IEEE 802.11 pairwise transient key (PTK) is derived from what cryptographic element?
A. Phase shift key (PSK)
B. Group master key (GMK)
C. Peerkey (PK)
D. Group temporal key (GTK)
E. Pairwise master key (PMK)
What wireless authentication technologies build a TLS-encrypted tunnel between the supplicant and the authentication server before passing client authentication credentials to the authentication server? (Choose 3)
Given:ABC Company has recently installed a WLAN controller and configured it to support WPA2- Enterprise security. The administrator has confirmed a security profile on the WLAN controller for each group within the company (manufacturing, sales, and engineering)
How are authenticated users assigned to groups so that they receive the correct security profile within the WLAN controller?
A. The WLAN controller polls the RADIUS server for a complete list of authenticated users and groups
after each user authentication.
B. The RADIUS server forwards a request for a group attribute to an LDAP database service, and LDAP
sends the group attribute to the WLAN controller.
C. The RADIUS server sends a group name return list attribute to the WLAN controller during every
successful user authentication.
D. The RADIUS server sends the list of authenticated users and groups to the WLAN controller as a
part of a 4-way handshake prior to user authentication.
Given:Jane Smith works primarily from home and public wireless hot spot rather than commuting to the office. She frequently accesses the office network frequently from her laptop using the 802.11 WLAN.
To safeguard her data, what wireless security policy items should be implemented? (Choose 2)
A. Use 802.1X/PEAPv0 to connect to the corporate office network.
B. Use secure protocols, such as FTP, for remote file transfer with encryption.
C. Use an IPSec VPN for connectivity to the office network.
D. Use an HTTPS captive portal for authent6ication at hot spots.
E. Use WIPS sensor software to monitor for risks.
F. Use personal firewall software on her laptop.
What is illustrated on the RF spectrum analyzer?
A. A low-power narrow band RF attacks is in progress on channel 11, causing significant 802.11 interference.
B. A frequency hoping device is being used as a signal jammer on channel 11 only.
C. An HR/DSSS AP and an ERP AP are both operating on channel 11 simultaneously.
D. An ERP AP operating normally on channel 11.
What security weakness is presented in pre-RSNA system using 802.1X with dynamic WEP?
A. There is support for authentication of individual users.
B. All version of EAP used with dynamic WEP pass the user name across the wireless medium in clear text.
C. The session key is crackable if enough traffic is transmitted using the key.
D. With out notification, APs downgrade the security mechanism to 104-bit static WEP when the client
device does not support dynamic WEP.
In what deployment scenarios would it be desirable to enable peer-to-peer traffic blocking?
A. In home networks in which file and pointer sharing is enabled
B. In corporate VoWiFi is networks with push to talk multicast capabilities
C. At public hotspots in which many clients use diverse application
D. In university environment with multicast training
What type of system is installed in graphics?
A. Distributed RF spectrum analyzer
B. Wireless Intrusion Prevention System
C. WLAN Controller Device Monitors
D. WLAN Emulation System
E. Wireless VPN Management System
Given:Many corporations have guest VLANs configured on their WLAN controller that allow visitors to have wireless internet access only.
What risks are associated with implementing the guest VLAN without any protocol filtering features enabled? (Choose 2)
A. Unauthorized users can perform internet based network attacks through the WLAN.
B. Intruders can send spam to the internet through the guest VLAN.
C. Peer-to-peer attacks between the guest users can not be prevented without protocol filtering.
D. Once guest users are associated to the WLAN, they can capture 802.11 frames from the corporate VLANs.
E. Guest users can reconfigure APs in the guest VKAN unless unsecure network management protocols
(e.g. Telnet, HTTP) are filtered.
Joe’s new laptop is experiencing difficulty connecting to ABC Company’s 802.11 WLAN using 802.1X/EAPPEAPv0. The company’s wireless network action network administrator assured Joe that his laptop was authorized in the WIPS for connectivity to all marketing department APs before it was given to him yesterday the WIPS terminations given to him yesterday. The WIPS termination policy is shown in exhibit.
Whatis apossible reason that Joe can not connect to the network?
A. Joe disabled his laptop’s integrated 802.11 radio and is using a personal PC card radio with a different
chipset, drivers, and client utilities.
B. An ASLEAP attack has been detected on APs to which Joe’s laptop was trying to associate.
This WIPS responded by disabling the APs.
C. Joe’s 802.11radio sending too many probe request and EAPoL start frame due to corrupted driver.
D. Joe configured his 802.11 radio card to transmit at 100mW to increase his SNR. The WIPS is detecting
his much out put power as a DoS attack.
E. Joe changed the system limit on his computer, and WIPS is detecting this as usage time violation.
