- D . TVHT
XYZ Company has decided to install an 802.11 WLAN system that will support 1000 wireless users, but they are concerned about network security.
XYZ is interested in deploying standardized security features. In addition to WPA2-Enterprise with PEAP and role-based access control, XYZ would like to support management frame protection as well as a fast secure roaming protocol for future mobile handsets.
As XYZ Company selects a product to deploy, what two IEEE amendments, which are included in 802.11-2012, should be supported to provide the management frame protection and fast secure roaming security features? (Choose 2)
- A . 802.11j
- B . 802.11p
- C . 802.11r
- D . 802.11u
- E . 802.11w
- F . 802.11z
In an 802.11n 2.4 GHz BSS, what prevents each station from using the full network bandwidth (e.g. 130 Mbps) for user data throughput when multiple clients are actively exchanging data with the AP? (Choose 2)
- A . Radio receiver hardware cannot process data as quickly as it can be transmitted.
- B . Half of the bandwidth is allocated to uplink traffic and half to downlink traffic.
- C . The DCF and EDCA coordination functions require backoff algorithms
- D . WLAN devices cannot detect collisions and must receive positive frame acknowledgment.
- E . APs do not have sufficient wired connection speeds to the LAN.
You are reporting on the RF environment in your facility. The manager asks you to describe the noise floor noted in the report.
Which of the following is the best explanation?
- A . The noise caused by elevators, microwave ovens, and video transmitters.
- B . The extra energy radiated by access points and client devices beyond that intended for the signal.
- C . The energy radiated by flooring materials that causes interference in the 2.4 GHz and 5 GHz bands.
- D . The RF energy that exists in the environment from intentional and unintentional RF radiators that forms the baseline above which the intentional signal of your WLAN must exist.
What would be needed for multiple basic service sets (BSSs) to exist within the same coverage area of a single access point and in that coverage area, all the client stations would be segmented in separate layer 2 and 3 domains but all communicate within a single layer 1 RF domain? (Choose all that apply.)
- A . Virtual BSSIDs
- B . SSIDs
- C . VLANs
- D . Autonomous APs
- E . None of the above
What is another name for a wireless hijacking attack?
- A . Wi-Fi phishing
- B . Man-in-the-middle
- C . Fake AP
- D . Evil twin
- E . AirSpy
Which ESS design scenario is required by the IEEE 802.11-2020 standard?
- A . Two or more access points with overlapping coverage cells
- B . Two or more access points with overlapping disjointed coverage cells
- C . One access point with a single BSA
- D . Two basic service sets interconnected by a distribution system medium (DSM)
- E . None of the above
A Type 2 PSE will perform a two-event Physical layer classification or Data-Link layer classification.
If mutual identification cannot be completed, what does the Type 2 device do?
- A . Defaults as a Category 0 device.
- B . PoE cannot be enabled.
- C . Operates as a Type 1 device.
- D . Provides 15.4 watts of power using Alternative A.
