  B. Flex + Bridge

• Question 42:

  What is the recommended cell overlap for WLAN design that supports voice traffic?

  A. 5%-10%
  B. 10%-15%
  C. 15%-20%
  D. 25%-30%
  C. 15%-20%

• Question 43:

  Which antenna type is most appropriate for covering a long hallway?

  A. Omnidirectional
  B. Patch
  C. Yagi
  D. Dipole
  C. Yagi

• Question 44:

  A customer is looking for a network design with Cisco Hyperloctation using AP4800 for location tracking via a custom mobile app Issues appeared in the past with refresh rates for location updates. What needs to be implemented to meet these requirements?

  A. Cisco CMX SDK in the location app
  B. redundant CMX and fetch location in round-robin fashion.
  C. device Bluetooth via the app
  D. Cisco FastLocate technology
  D. Cisco FastLocate technology

  ---

  Cisco FastLocate technology is part of the Cisco Hyperlocation solution, which enhances location tracking accuracy and refresh rates. Implementing Cisco FastLocate technology can address issues with refresh rates for location updates in a custom mobile app by increasing the number of location data points captured, thus providing more frequent and accurate location updates.

• Question 45:

  In a high-density stadium deployment, which two design considerations are most important?

  A. Use of high-gain omni antennas and 2.4 GHz channels
  B. Coverage overlap of 50% and fewer APs
  C. Sectorized directional antennas and channel reuse planning
  D. Single large AP with maximum transmit power
  C. Sectorized directional antennas and channel reuse planning

• Question 46:

  A company wants to replace its existing PBX system with a new VoIP System that will include wireless IP phones. The CIO has concerns about whether the company's existing wireless network can support the new system. Which tool in Cisco Prime can help ensure that the current network will support the new phone system?

  A. Location Readiness
  B. Site Calibration
  C. Map Editor
  D. Voice Readiness
  D. Voice Readiness

  ---

  The Voice Readiness tool within Cisco Prime Infrastructure is designed to assess the wireless network's ability to support voice services, including VoIP. It evaluates various factors such as signal strength, noise levels, and coverage to ensure that the wireless network can handle the quality of service requirements needed for voice communications.

• Question 47:

  An engineer in a branch office that does not have a wired backhaul must ensure that local clients can be switched locally and authenticated centrally. In which mode must the AP be configured?

  A. RAP
  B. Flex+Bridge
  C. MAP
  D. Cisco FlexConnect
  D. Cisco FlexConnect

  ---

  Cisco FlexConnect mode is designed for branch offices that lack a wired backhaul. It allows APs to switch client data traffic locally while still performing client authentication centrally. This mode provides the flexibility needed for branch deployments, ensuring that client traffic is handled efficiently even if the WAN link to the central site is down.

• Question 48:

  Which non-Wi-Fi interferer can be identified by Metageek Chanalyzer?

  A. PDAs
  B. jammers
  C. smartphones
  D. printers
  B. jammers

  ---

  Jammers are non-Wi-Fi interferers that can be identified by Metageek Chanalyzer. They intentionally disrupt wireless communications by emitting radio frequencies that interfere with Wi-Fi signals. Chanalyzer is designed to detect such patterns of interference. https://www.metageek.com/training/resources/wifi-and-non-wifi-interference

• Question 49:

  A network consultant must create a wireless design with these characteristics:

  1.

  Provide coverage in a single contiguous space.

  2.

  Support dual-band wireless coverage.

  3.

  Use nine APs for full coverage in a 5 GHz band.

  What must the engineer do to mitigate co-channel interference and maintain coverage in 2.4 GHz?

  A. Adjust the TPC neighbor threshold value to -64 dBm on the 2.4 GHz band.
  B. Configure static channel and power settings of the 2.4 GHz radios.
  C. Disable 2.4 GHz radios on selective APs.
  D. Deactivate low data rates on the 2.4 GHz band.
  C. Disable 2.4 GHz radios on selective APs.

  ---

  In a high-density environment where 5 GHz coverage is provided by nine APs, disabling the 2.4 GHz radios on some APs can reduce co-channel interference because the 2.4 GHz band has fewer non-overlapping channels. This approach helps maintain coverage while mitigating interference.

• Question 50:

  When designing for high-density environments such as stadiums, which is MOST important?

  A. Use of omnidirectional antennas
  B. Increase transmit power of APs
  C. Use of directional antennas with sectorization
  D. Deploying APs only on 2.4 GHz
  C. Use of directional antennas with sectorization
