• A.PLCP Protocol Data Unit (PPDU)
• B.MAC Service Data Unit(MSDU)
• C.PLCP Service Data Unit (PSDU)
• D.MAC Protocol Data Unit (MPDU)

In addition to throughput enhancements, what other improvements does a dual-band
802.11ac AP provide when compared with 802.11a/g APs? (Choose 2)

• A.Better link reliability between 802.11a/b/g client devices and 802.11ac APs
• B.Stronger security with more robust encryption modes.
• C.Increases in receive sensitivity enhance RTLS location accuracy
• D.Introduces "fast transition" roaming protocols for VoWiFi phones
• E.Improves service quality for real-time applications at greater distances

In an infrastructure Basic Service Set (BSS), how does the passive scanning process occur?

• A.Client stations broadcast Probe Request frames on the singlechannel forwhich they are programmed. Nearby access points respond on that channel with Probe Response frames.
  Client stations record information found in the Probe Response frames for use in the association process.
• B.Client stations broadcast Probe Request frames on all supportedchannels inthe regulatory domain. Nearby access points respond with Probe Response frames. Client stations record information in the Probe Response frames for use in the association process.
• C.Access points broadcast Beacons on asingle channel for which they are programmed.
  Nearby client stations listen for Beacon frames and record information found in the
  Beacons for use in the association process.
• D.Access pointsbroadcast Beacons on all channels of each radio within the regulatory domain. Nearby client stations record information found in the Beacons for use in the association process.

You are selecting antennas for a WLAN operating in the 5 GHz frequency band. What specifications should be evaluated for an antenna before it is implemented in this WLAN system?

• A.Impedance in Ohms
• B.802.11ad compatibility
• C.Return Loss Rating
• D.TPC support

AP-1 is a 3x3:2 AP. STA-3 is a 3x3:3 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.Two spatial streams, because the definition of the AP indicates that it is capable of only two spatial streams.
• B.Three spatial streams, because the definition of the client indicates that it is capable of only three spatial streams.
• C.Three spatial streams, because the definition of the AP indicates that it is capable of only three spatial streams.
• D.One spatial stream, because the definition of the AP indicates that it is capable of only one spatial stream.
