Which of the following statements are true about amplification? (Choose all that apply.)
- A . All antennas require an outside power source.
- B . RF amplifiers require an outside power source.
- C . Antennas are passive gain amplifiers that focus the energy of a signal.
- D . RF amplifiers passively increase signal strength by focusing the AC current of the signal.

Users and Network support personnel at a mid-sized equipment manufacturer have been discussing the potential uses and benefits of implementing an indoor WLAN.
The network administrator and network manager have requested a meeting of senior management personnel to discuss a WLAN implementation before performing a site survey or taking any implementation steps. The first topic of discussion in the meeting is the corporate policy concerning implementation and use of WLAN technology.
What specific topics are appropriate in this policy meeting? (Choose 2)
- A . Use of the latest 802.11ac equipment
- B . Business justification
- C . User productivity impact
- D . Antenna types
- E . Defining RF channels for use
AP-1 is a 3×3:2 AP. STA-3 is a 3×3:3 client.
What is the maximum number of spatial streams that can be used for a downlink HT-OFDM transmission from AP-1 to STA-3?
- A . One spatial stream, because the definition of the AP indicates that it is capable of only one spatial stream.
- B . Three spatial streams, because the definition of the client indicates that it is capable of only three spatial streams.
- C . Two spatial streams, because the definition of the AP indicates that it is capable of only two spatial streams.
- D . Three spatial streams, because the definition of the AP indicates that it is capable of only three spatial streams.
What is the difference between association frames and reassociation frames?
- A . Association frames are management frames, whereas reassociation frames are control frames.
- B . Association frames are used exclusively for roaming.
- C . Reassociation frames contain the BSSID of the original AP.
- D . Only association frames are used to join a BSS.
Which type of site survey uses modeling algorithms and attenuation values to create visual models of RF coverage cells?
- A . Associated
- B . Passive
- C . Predictive
- D . Assisted
- E . Active
Which of these attacks can be mitigated with a mutual authentication solution? (Choose all that apply.)
- A . Malicious eavesdropping
- B . Deauthentication
- C . Man-in-the-middle
- D . Wireless hijacking
- E . Authentication flood
The Wi-Fi Alliance certification called Wi-Fi Multimedia (WMM) is based on which media access method defined by the 802.11-2012 standard?
- A . DCF
- B . PCF
- C . EDCA
