Cisco 300-360 Online Questions & Answers

• Question 21:

  An engineer has performed a post-deployment site survey and noticed that access points were installed in suboptimal locations due to physical restrictions and obstacles. Which action must the engineer take to resolve this deployment issue?

  A. Set DCA Channel Assignment Method to freeze.
  B. Set all Auto RF parameters to factory default
  C. Set TPC maximum and minimum power levels.
  D. Set static channels on all AP radios.
  C. Set TPC maximum and minimum power levels.

  Suspect poor coverage/not enough AP density -- If AP transmit power is already at the maximum, you can enable the lower data rates to allow clients to connect from farther away. This has a negative impact on performance, but it can help the customer understand that additional APs might be necessary. https:// www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/116057-site-survey - guidelines-wlan-00.html

  A. overlapping -72 dBm coverage from two access points
  B. overlapping -67 dBm coverage from two access points
  C. continuous -67 dBm coverage from one access point
  D. continuous -72 dBm coverage from one access point
  C. continuous -67 dBm coverage from one access point

• Question 25:

  An engineer must perform a survey where the target client devices range from standard Wi-Fi-equipped laptops, consumer handhelds and tablets, and low power tracking tags limited to 12 mW Tx power. With which setting should the survey AP be configured?

  A. local power 11
  B. local power 5
  C. local power 14
  D. local power 8
  B. local power 5

• Question 26:

  An engineer is preparing for an active site survey of a warehouse and is informed that they should not enter any areas that are blocked by supplies that are difficult to move. Which option describes how the engineer should address this restriction?

  A. Extrapolate restricted access areas by drawing circles for AP coverage
  B. Survey hallways, common areas, and storerooms.
  C. Utilize a predictive tool to define coverage in off-limits areas.
  D. Educate the customer about the importance of accurate and complete measurements.
  C. Utilize a predictive tool to define coverage in off-limits areas.

• Question 27:

  A wireless engineer is configuring VoWLAN on a WLC.

  Which configuration should be implemented on the router or switch that is connected to the WLC?

  A. The interface on the switch or router should trust the CoS settings of the WLC.
  B. The interface on the WLC should mark all packets as EF.
  C. The interface on the switch or router should strip all CoS markings on the IEEE 802.11 header.
  D. The interface must be configured as a Layer 3 interface.
  A. The interface on the switch or router should trust the CoS settings of the WLC.

  ---

  We recommend that the QoS policy on the router/switch interfaces connected to the WLC be set to trust the CoS settings of the WLC. This means that the wired network responds to the CoS values controlled by the QoS policy set on the WLC. The WLC does not enforce any policy that changes the WLAN client DSCP values. The WLC policy effects will only be seen in the CoS values associated with the WLAN client traffic. If the routers and switches connecting to the WLC are set to trust DSCP, then a DSCP policy must be created and maintained on those router and switch interfaces--in addition to the policies applied on the WLC. For more information on WLAN QoS and traffic classification, refer to the Chapter 3, "Voice over WLAN Radio Frequency Design".

• Question 28:

  Which three recommendations must be taken into consideration when an engineer is installing a new Voice WLAN? (Choose three.)

  A. Use the Cisco wireless phone site survey client utility.
  B. Use a separate Cisco Wireless Lan Controller.
  C. Enable load balance on voice WLANs.
  D. Maintain -67dBM as a minimal RSSI.
  E. Set data for 2.4 GHz and voice for 5 GHz using separate SSIDs.
  F. Enable lower data rates for 2.4-GHz data WLAN.
  A. Use the Cisco wireless phone site survey client utility.
  D. Maintain -67dBM as a minimal RSSI.
  E. Set data for 2.4 GHz and voice for 5 GHz using separate SSIDs.

• Question 29:

  A customer is deploying a mesh outdoor wireless network based on FCC standards where spectrum analysis shows significant radar energy propagating throughout the coverage area from a local weather station. Which channel must be excluded from the access points RRM calculation to avoid network disruption due to weather radar activity?

  A. 132
  B. 44
  C. 11
  D. 36
  A. 132

  ---

  Weather radars operate within the 5600- to 5650-MHz band, which means that channels 124 and 128 might be affected, but also channels 120 and 132 might suffer from weather radar activity.

• Question 30:

  You are designing a wireless network to support high user density in the 5 GHz spectrum. Which option is the benefit of selecting a channel width of 20 MHz instead of selecting a higher channel width?

  A. increased bandwidth
  B. increased throughput
  C. decreased co-channel interference
  D. decreased speed
  C. decreased co-channel interference

  ---

  If forced to reuse 5 GHz channels, more consistent results will be delivered using strictly 20 MHz channels and avoiding loss of efficiency due to CCI. https://www.cisco.com/c/en/us/products/collateral/wireless/aironet-1250-series/design_guide_c07-693245.html#_Toc309331077
