Cisco 300-425 Online Questions & Answers

• Question 81:

  Based on a wireless network design, an engineer configured a primary and secondary controller for their APs. A power interruption caused the primary Cisco WLC to go down, and, as expected, all APs joined the secondary controller. When the primary controller came back up, all the APs remained joined to the secondary controller. Which approach must the engineer take for the APs to move back to the primary?

  A. Set AP Failover Priority to 4 on each AP.
  B. Set AP Fallback to Enabled on the secondary controller.
  C. Set AP Fallback to Enabled on the primary controller.
  D. Set AP Failover Priority to Critical globally.
  C. Set AP Fallback to Enabled on the primary controller.

  ---

  AP Fallback is a feature that allows APs to rejoin their primary controller after they have connected to a secondary controller due to a failure. By enabling AP Fallback on the primary controller, the APs will automatically rejoin it when it becomes available again after a power interruption. This ensures that APs return to their designated primary controller for normal operations.

• Question 82:

  Which two factors influence the roaming decision of a wireless client? (Choose two.)

  A. Signal-to-Noise Ratio (SNR)
  B. Access point channel number
  C. Received Signal Strength Indicator (RSSI)
  D. AP transmit power
  E. Client's roaming algorithm
  C. Received Signal Strength Indicator (RSSI)
  E. Client's roaming algorithm

• Question 83:

  An engineer must ensure that the wireless network can accomplish fast secure roaming by way of caching keys on the access points. Which key caching mechanism is enabled by default on a Cisco AireOS WLC?

  A. SKC
  B. OKC
  C. 802.11r
  D. CCKM
  B. OKC

• Question 84:

  Which two criteria must be considered when conducting an outdoor bridge site survey? (Choose two.)

  A. near-far effect
  B. weather
  C. traffic lights
  D. power lines
  E. Fresnel zone
  B. weather
  E. Fresnel zone

  ---

  When conducting an outdoor bridge site survey, weather and the Fresnel zone are critical criteria to consider. Weather can affect signal propagation and the reliability of the wireless link, while the Fresnel zone relates to the elliptical area around the line-of-sight path between transceivers, which must be clear of obstacles to ensure a strong signal.

• Question 85:

  A customer is deploying an 802.11ac network on a floor to support approximately 300 wireless devices. Which setting must be changed on Cisco Prime Infrastructure Planning Tool to predict the number of APs the customer needs to service the new floor?

  A. Demand Settings
  B. Data Coverage Support Margin
  C. 802.11n Protocol Support
  D. Add AP Field
  A. Demand Settings

  ---

  To predict the number of APs needed to support approximately 300 wireless devices on a new floor with an 802.11ac network, the Demand Settings in the Cisco Prime Infrastructure Planning Tool must be adjusted. This setting allows the planner to specify client density and throughput requirements, which are crucial for determining the correct number of APs.

• Question 86:

  A new wireless network design has these requirements:

  1.

  AireOS WLCs as guest anchors

  2.

  a Cisco Catalyst 9800 Series WLC as the foreign controller

  3.

  use of Wi-Fi 6 APs

  4.

  inter-controller roaming for guest users

  Which two design approaches meet these requirements? (Choose two.)

  A. Use EoIP for communication between controllers.
  B. Use WLC software versions that support IRCM.
  C. Use AVC on the anchor WLCs.
  D. Use IPv6 across the wireless network.
  E. Use secure mobility to pair controllers.
  B. Use WLC software versions that support IRCM.
  E. Use secure mobility to pair controllers.

• Question 87:

  During a meeting to gather the requirements for a new Wi-Fi network design, the customer requests that 802.11a and 802.11ac clients be able to connect. Which affect does this have to the wireless network?

  A. bigger channel width
  B. lower throughput
  C. 2.4 GHz signal congestion
  D. higher RF reflection
  B. lower throughput

• Question 88:

  DRAG DROP

  A wireless consultant is creating a wireless design for a multistory building. The building will house several groups that will use the wireless network for different operations. Depending on how the wireless network is used, different wireless approach designs must be taken. Drag and drop the services from the left onto the AP density levels on the right based on the wireless deployment requirements.

• Question 89:

  An engineer must produce a passive survey report. The coverage heat map shows the entire site with all signal levels. To see only the desired coverage, which action must the engineer take?

  A. Change the color scheme to show the desired heat map.
  B. Use the RSSI calibration tool to configure the receiver sensitivity.
  C. Use the RSSI slider to set the heat map to the desired cutoff filter.
  D. Filter the results to show the desired APs only.
  C. Use the RSSI slider to set the heat map to the desired cutoff filter.

  ---

  To focus the coverage heat map on the desired coverage, the engineer should use the RSSI slider to set the heat map to the desired cutoff filter. This action will adjust the display to show only the signal levels that meet or exceed the specified RSSI value, effectively filtering out weaker signals and highlighting areas with sufficient coverage.

• Question 90:

  A wireless engineer is getting ready to perform a predictive site survey. The new network needs to support data and voice over wireless. Which two Cisco recommendations should be considered for the design? (Choose two.)

  A. Set -19 dBm of separation between APs on the same channel.
  B. Use the 5 GHz radio band due to 40 MHz bandwidth capability.
  C. Use the 5 GHz radio band due to the 24 non-overlapping channels.
  D. Set the cell boundary to -67 dBm.
  E. Set the cell overlap to 15%
  C. Use the 5 GHz radio band due to the 24 non-overlapping channels.
  D. Set the cell boundary to -67 dBm.
