• Question 92:

  One of your customers plans on providing wireless coverage to a warehouse facility. After performing an initial walkthrough, you collect the following information:

  The central part of the warehouse is between 400 and 600 feet (122 to 183 meters) from the warehouse switches mounted on the walls.

  # The warehouse storage is composed of metallic racks with varying inventory levels and contents, from electronics and plastic toys to food pallets and juice bottles. # Workers need basic data coverage from their working location, and are not

  highly mobile. They usually work from one single aisle, and their laptop is on a cart with wheels.

  What would be your one recommendation to provide coverage to the central area of the warehouse?

  A. Equip workers laptops with a directional antenna and install APs less than 328 feet (100m) away from the switch.
  B. In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as possible to the central area of the warehouse.
  C. Position APs along the walls, and equip the APs with Yagi antennas to cover the central area.
  D. Install APs for client access in the central area and use a mesh backhaul link to connect to the DS.
  B. In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as possible to the central area of the warehouse.

• Question 93:

  The installation crew for your WLAN project wants to install a few APs to locations nearby the ones specified in the RF design document. What next step should occur? Response:

  A. Confirm the mounting hardware.
  B. Choose a different AP model.
  C. Update the documentation.
  D. Consult the RF designer.
  D. Consult the RF designer.

• Question 94:

  ABC Company has a WLAN controller with 10 controller-based APs; the Voice SSID is configured for centralized data forwarding. Each AP is connected to an access port on a layer-2 Ethernet switch. Each layer-2 switch is uplinked to a single layer-3 core Ethernet switch. The WLAN controller is connected directly to the layer-3 core Ethernet switch. Layer-3 tunnels are created between all controller-based APs and the WLAN controller. A voice server is connected to the layer-3 Ethernet switch.

  When a voice-enabled QoS STA sends an IP data packet to a voice server in this scenario, the DSCP value carried in the STA's IP data packet gets mapped to what and by which device?

  A. The DSCP value is mapped to an IEEE 802.1Q priority tag value by the WLAN controller.
  B. The DSCP value is mapped to the DSCP value in the encapsulating IP header by the layer-3 switch.
  C. The DSCP value is mapped to an IEEE 802.1p (802.1D-2004) UP value by the access point.
  D. The DSCP value is mapped to an IEEE 802.1Q VLAN tag by the access point.
  A. The DSCP value is mapped to an IEEE 802.1Q priority tag value by the WLAN controller.

• Question 95:

  During a post-validation survey, you find an area lacking any detectable Wi-Fi signal at all It is located behind an elevator shaft What is a common solution to this problem?

  A. Move one or more APs so that indoor propagation results in coverage in that area or install another AP on that side of the elevator shaft
  B. Turn up the power on the three APs closes! to that area
  C. Install antennas with at least 3 more dB of gain on the two APs closest to that area
  D. Replace all the clients in that area with clients having better receive sensitivity
  A. Move one or more APs so that indoor propagation results in coverage in that area or install another AP on that side of the elevator shaft

• Question 96:

  What is an advantage of centralized data forwarding?

  A. It reduces delay for user traffic
  B. It increases the encryption strength for user traffic
  C. It increases the signal strength for wireless client devices
  D. It allows for centralized filtering of wireless traffic
  D. It allows for centralized filtering of wireless traffic

• Question 97:

  During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent. Every other time of the day, it works fine. What's the likely cause of this issue? Response:

  A. Employees are using their cell data instead of using the Wi-Fi
  B. The AP in the cafeteria keeps rebooting due to lack of PoE budget on the switch
  C. Microwaves in the cafeteria are interfering with the Wi-Fi on the 2.4 GHz band
  D. Toasters and ovens are heating up the air, raising the noise floor with the Wi-Fi on the 2.4 Ghz band
  C. Microwaves in the cafeteria are interfering with the Wi-Fi on the 2.4 GHz band

• Question 98:

  When selecting a centralized WLAN architecture, what new problem may arise when you change the data forwarding model from centralized to distributed? Response:

  A. Centralized control functions, such as key management and distribution, RRM, and load balancing will no longer be supported.
  B. The router between the APs and the controller must be made aware of the APs as forwarding client STAs.
  C. APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.
  D. All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit power arbiter for other APs in the ESS.
  C. APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.

• Question 99:

  When viewing channel utilization information from a protocol analyzer, if high channel utilization is occurring, what should you ensure does not exist? Response:

  A. A high percentage of low PHY rates
  B. An RF signal generator causing an RF DoS
  C. High levels of workload
  D. High frames per second
  A. A high percentage of low PHY rates

• Question 100:

  A business traveler from North America is in Europe. The hotel only provides coverage in 2.4 GHz. The traveler connects to the hotel's SSID and notices an AP in the hotel room. However, the laptop reports a very low RSSI when connected. The traveler does not have the same problem when connecting in the lobby. What would be the most likely cause of the low RSSI in the hotel room?

  A. The AP in the room is using ZigBee instead of Wi-Fi.
  B. The AP in the room is transmitting on channel 13 and the traveler associated to a non-channel 13 AP located elsewhere.
  C. The switchport that the AP is connected to is only capable of transmitting at 10 Mbps.
  D. The AP in the room is using Bluetooth instead of Wi-Fi.
  B. The AP in the room is transmitting on channel 13 and the traveler associated to a non-channel 13 AP located elsewhere.
