The IEEE 802.11 standard defined Open System authentication as consisting of two auth frames and two assoc frames. In a WPA2-Enterprise network, what process immediately follows the 802.11 association procedure?
What EAP type supports using MS-CHAPv2, EAP-GTC or EAP-TLS for wireless client authentication?
While performing a manual scan of your environment using a spectrum analyzer on a laptop computer, you notice a signal in the real time FFT view. The signal is characterized by having peak power centered on channel 11 with an approximate width of 20 MHz at its peak. The signal widens to approximately 40 MHz after it has weakened by about 30 dB.
What kind of signal is displayed in the spectrum analyzer?
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?
Given: Fred works primarily from home and public wireless hot-spots rather than commuting to the office. He frequently accesses the office network remotely from his Mac laptop using the local 802.11 WLAN.
In this remote scenario, what single wireless security practice will provide the greatest security for Fred?
What statement accurately describes the functionality of the IEEE 802.1X standard?
Given: You must implement 7 APs for a branch office location in your organization. All APs will be autonomous and provide the same two SSIDs (CORP1879 and Guest).
Because each AP is managed directly through a web-based interface, what must be changed on every AP before enabling the WLANs to ensure proper staging procedures are followed?
Given: Many corporations configure guest VLANs on their WLAN controllers that allow visitors to have Internet access only. The guest traffic is tunneled to the DMZ to prevent some security risks.
In this deployment, what risks are still associated with implementing the guest VLAN without any advanced traffic monitoring or filtering features enabled? (Choose 2)
What are the three roles of the 802.1X framework, as defined by the 802.1X standard, that are performed by the client STA, the AP (or WLAN controller), and the RADIUS server? (Choose 3)
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?
