What can be delivered over the air to WLAN mobile devices, such as tablets and smartphones, when a mobile device management (MDM) solution is deployed?
- A . Configuration settings
- B . Applications
- C . Certificates
- D . Web clips
- E . All of the above
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.
Which sublayer of the OSI model’s Data-Link layer is used for communication between 802.11 radios?
- A . LLC
- B . WPA
- C . MAC
- D . FSK
Select the four labels that a WIPS uses to classify an 802.11 device.
- A . Infrastructure
- B . Known
- C . Enabled
- D . Disabled
- E . Rogue
- F . Unknown
Wi-Fi technology is used in many different vertical markets.
Which of these vertical markets use Wi-Fi for inventory control? (Choose all that apply.)
- A . Retail
- B . Manufacturing
- C . Education
- D . Law enforcement
- E . Hotspots
How is throughput capacity scaled in a single channel architecture (SCA) WLAN system?
- A . By increasing transmit power and placing APs that are on a single channel farther from one another.
- B . By adding more SSIDs to existing APs to spread users across different contention domains.
- C . By adding non-overlapping channel layers through the addition of more APs.
- D . By using downlink data compression and uplink flow control at the AP.
- E . By using a single 802.11n radio to transmit simultaneous downlink data streams to different users.
ABC Hospital is planning a Wi-Fi infrastructure upgrade where the 802.11b/g APs (HR/DSSS and ERP) would be replaced with new dual-radio 802.11n/802.11ac (HT and VHT) APs. ABC wants to minimize the time and cost associated with performing a new site survey, so they will be mounting all of the new APs in the same locations and with the same cable drops as the existing APs.
What is one performance drawback with this deployment method?
- A . Multipath will increase, causing excessive layer-2 retransmissions. The retransmissions will cause latency for VoWiFi handsets.
- B . Increased receiver sensitivity on the VHT APs will cause them to continually change channels to avoid co-channel interference.
- C . If the existing UTP cabling is not Category 3 or better, the total Ethernet backhaul for each AP will be limited to 100 Mbps.
- D . The existing WLAN plan, including the AP locations, may not provide the benefits seen in HT and VHT 802.11 PHY capabilities.
What can be done to fix the hidden node problem? (Choose all that apply.)
- A . Increase the power on the access point.
- B . Move the hidden node station.
- C . Increase power on all client stations.
- D . Remove the obstacle.
- E . Decrease power on the hidden node station.
VHT radios are backward compatible with which of the following type of 802.11 technology? (Choose all that apply.)
- A . Clause 17 radios (HR-DSSS)
- B . Clause 18 radios (OFDM)
- C . Clause 14 radios (FHSS)
- D . Clause 19 radios (ERP)
- E . Clause 20 radios (HT)
Which 802.11 service set is defined specifically for directional multi-gigabit (DMG) radios?
- A . BSS
- B . ESS
- C . IBSS
- D . PBSS
- E . MBSS
