• Question 3:

  Given:

  XYZ Company is planning to install a new 802.11 WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. XYZ has hired you to perform the RF site survey. During the interview with the network

  After hearing this information, what immediate concerns do you note?

  A. VoIP phones and 802.11 access points should not be powered by the same edge switch due to distortion.
  B. The edge Ethernet switches will need to support 802.3at PoE in order to support both access points and VoIP phones.
  C. If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal locations for 802.11 APs.
  D. The power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices.
  D. The power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices.

  A. Spatial multiplexing
  D. Space-time block coding

• Question 5:

  Given: You are an independent contractor, hired to perform an indoor site survey and network design for ABC Hotel. The network will support both hotel staff and guest users. You are interviewing the network manager to determine business, performance, and security requirements for the future 802.11 WLAN.

  What questions should you ask the IT manager? (Choose two)

  A. What data cabling is currently installed in the rooms and throughout the hotel?
  B. How much RF loss do you expect between hotel rooms?
  C. Where are the RF dead zones located within the facility?
  D. What types of applications will be used by the hotel staff?
  E. Are there any radar systems in use at the hotel that would conflict with the WLAN?
  A. What data cabling is currently installed in the rooms and throughout the hotel?
  D. What types of applications will be used by the hotel staff?

• Question 6:

  What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) in IEEE 802.11 WLANs?

  A. 802.11a and 11n use six (6) "pilot" subcarriers as a reference for the receiver to detect frequency and phase shifts of the signal.
  B. 802.11a/g/n OFDM includes several combinations of modulation and coding to achieve data rates from 1-600 Mbps.
  C. With 802.11a OFDM, 16-QAM provides either 48 or 54 Mbps data rates, depending upon coding rates.
  D. 802.11n HT-OFDM utilizes 256-QAM, which increases the data rate from 54 Mbps (with 64-QAM) up to 65 Mbps.
  E. In 802.11a OFDM, forty-eight (48) subcarriers are used as parallel symbol transmission paths to carry data.
  E. In 802.11a OFDM, forty-eight (48) subcarriers are used as parallel symbol transmission paths to carry data.

• Question 7:

  What factors will have the most significant affect on the amount of wireless bandwidth available to each station within a BSS? (Choose two)

  A. The number of client stations associated to the BSS
  B. The power management settings in the access point's beacons
  C. The presence of co-located (10m away) access points on non-overlapping channels
  D. The data rates at which nearby client stations are transmitting and receiving data
  E. The layer 3 protocol used by each station to transmit data over the wireless link
  A. The number of client stations associated to the BSS
  D. The data rates at which nearby client stations are transmitting and receiving data

• Question 8:

  What term correctly completes the following sentence?

  In an IEEE 802.11 frame, the IP packet is considered by the MAC layer to be a(n) _________.

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

• Question 9:

  What distinguishes an independent basic service set (IBSS) from an infrastructure basic service set (BSS)?

  A. An IBSS does not have a distribution system (DS), but a BSS does.
  B. An IBSS does not require beacon frames, but a BSS does.
  C. An IBSS does not support 802.11 authentication or association, but a BSS does.
  D. An IBSS can only operate on a single channel, but a BSS can operate on multiple channels.
  A. An IBSS does not have a distribution system (DS), but a BSS does.

• Question 10:

  Given: ABC Hospital is planning a Wi-Fi infrastructure upgrade where the 802.11b/g APs would be replaced with new dual-radio HT (802.11n) 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 HT APs will cause them to continually change channels to avoid co-channel interference.
  C. If the existing UTP cabling is not Category 6 or better, the total Ethernet backhaul for each AP will be limited to 100 Mbps.
  D. In locations with line-of-sight to client devices and little multipath, the benefits of MIMO may be less significant than in other areas.
  D. In locations with line-of-sight to client devices and little multipath, the benefits of MIMO may be less significant than in other areas.
