ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped
VoWiFi calls and leading to data connectivity and throughput problems. In addition to avoiding 2.4 GHz channels and installing a distributed spectrum analyzer to locate RF interference sources, what should the implementer do to resolve the problem fully?

  1. Have only guest access on the 5 GHz channels.
  2. Move all corporate data clients and VoWiFi devices to the 5 GHz channels appropriate for their regulatory domain.
  3. Use captive portals for guest authentication in 5 GHz.
  4. Implement WPA-PSK everywhere in the network.

Answer(s): B



When you see the SKINNY protocol in a post-install validation protocol capture, what does this indicate?

  1. Secure FTP is in use
  2. VoIP is used on the network
  3. HTTPS is in use
  4. Multicasting is used on the network

Answer(s): B



During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame showing an incorrect FCS.
This frame is typical of those that were captured by the analyzer.
What does this frame reveal about the RF network in this area?

  1. One station seems to be streaming video, thus may have reserved significant bandwidth via admission control
  2. Contention Free is in place in this network, which may starve some non-QoS stations from access
  3. Multipath or excessive collisions seem to be an issue in this area
  4. The AP seems to be too far to provide enough coverage to this area

Answer(s): C



Excessive uplink RTP frame retransmissions can result in ____________.

  1. Deauthentication of the transmitter by the receiver
  2. Lowering of the data transmission rate by the transmitting station
  3. MOS scores in excess of 5
  4. Head-of-Line blocking at the receiver

Answer(s): B



When designing a WLAN to support voice in a large office, which design element is of the highest concern for performance?

  1. Frequency Selection
  2. Roaming
  3. AP vendor
  4. Band steering

Answer(s): B
