Cisco 300-425 Online Questions & Answers

• Question 181:

  An engineer is designing an outdoor mesh network to cover several sports fields. The core of the network is located in a building at the entrance of a sports complex. Which type of antenna should be used with the RAP for backhaul connectivity?

  A. 5 GHz. 8-dBi omnidirectional antenna
  B. 2.4 GHz. 8-dBi patch antenna
  C. 2.4 GHz. 14-dBi omnidirectional antenna
  D. 5 GHz. 14-DBi patch antenna
  D. 5 GHz. 14-DBi patch antenna

  ---

  In an outdoor mesh network designed to cover sports fields, a 5 GHz, 14- dBi patch antenna is suitable for the RAP for backhaul connectivity. The higher gain and directional nature of a patch antenna help in focusing the signal over longer distances and in specific directions, which is ideal for connecting various points in a large outdoor area. https://www.cisco.com/c/en/us/products/collateral/wireless/aironet-antennas-accessories/product_data_sheet09186a008008883b.html

• Question 182:

  Which IEEE standard enables Fast BSS Transition (FT) for seamless roaming?

  A. 802.11k
  B. 802.11r
  C. 802.11v
  D. 802.11ac
  B. 802.11r

• Question 183:

  Which two wireless design principles help mitigate co-channel interference? (Choose two.)

  A. Use directional antennas
  B. Increase AP transmit power
  C. Use non-overlapping channels
  D. Place APs too close together
  E. Lower AP transmit power
  C. Use non-overlapping channels
  E. Lower AP transmit power

• Question 184:

  Which two considerations must a network engineer have when planning for voice over wireless roaming? (Choose two.)

  A. Full reauthentication introduces gaps in a voice conversation.
  B. Roaming time increases when using 802.1x + Cisco Centralized Key Management.
  C. Roaming occurs when the phone has seen at least four APs.
  D. Roaming occurs when the phone has reached-80 dBs or below.
  E. Roaming with only 802.1x authentication requires full reauthentication.
  A. Full reauthentication introduces gaps in a voice conversation.
  E. Roaming with only 802.1x authentication requires full reauthentication.

  ---

  Voice over wireless roaming is sensitive to delays and interruptions. Full reauthentication, as mentioned in option A, can cause noticeable gaps in a voice conversation because it requires time to re-establish security credentials. This process can interrupt the seamless experience expected in voice communications. Option E is also correct because roaming with only 802.1x authentication indeed requires full reauthentication, which can introduce significant delays affecting voice quality.

• Question 185:

  A customer requires that two wireless APs be installed in a reception area, in a historic building, the impact of the APs on the appearance of the reception area must be minimized. Which two AP antennas should be used? (Choose two.)

  A. AP with a Yagi antenna
  B. AP with a patch antenna
  C. AP with a monopole antenna
  D. AP with an integrated antenna
  E. AP with a dipole antenna
  A. AP with a Yagi antenna
  B. AP with a patch antenna

• Question 186:

  Which antenna type is best for covering a long corridor in a building?

  A. Omni-directional antenna
  B. Patch antenna
  C. Yagi antenna
  D. Dipole antenna
  B. Patch antenna

• Question 187:

  Which UDP port numbers are used for exchange mobility packets in an AireOS wireless deployment?

  A. UDP 16666 for control plane, EoIP (IP protocol 97) for data plane
  B. UDP 16668 for control plane, UDP 16667 for data plane
  C. UDP 16667 for control plane, UDP 16666 for data plane
  D. UDP 16666 for control plane, UDP 16667 for data plane
  D. UDP 16666 for control plane, UDP 16667 for data plane

• Question 188:

  An engineer must decide the cell overlap for a wireless voice deployment. Which Cisco measurement recommendation should be considered?

  A. The edge of the cell should be-67 dBm.
  B. The edge of the cell should be below 35 RSSI.
  C. The measurement should be done on the 2.4-GHz band.
  D. One AP should be deployed per 3000 square feet.
  A. The edge of the cell should be-67 dBm.

  ---

  Explanation Explanation/Reference:For a wireless voice deployment, Cisco recommends that the edge of the cell should have a signal strength of -67 dBm to ensure reliable voice quality and seamless roaming capabilities.

• Question 189:

  What is the recommended overlap percentage between adjacent AP cells in a data WLAN design?

  A. 5%
  B. 10%?5%
  C. 20%?0%
  D. 50%
  B. 10%?5%

• Question 190:

  Two cisco 5520 wireless LAN controllers are managing all access points throughout the network. The WLCs are in different locations to provide geographical redundancy a mobility group has been configured on both WLCs and has a UP status on both controllers. The Aps in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline. The Aps successfully join the WLC in location, but they do not fail over to their primary configured controller. Which configuration task fixes the issue?

  A. Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A Access points.
  B. Use DHCP Option 43 and specify WLC in location A as primary.
  C. Enable AP fallback globally on the WLC
  D. Change the AP Failover Priority to critical.
  C. Enable AP fallback globally on the WLC

  ---

  Enabling AP fallback globally on the WLC allows access points to reconnect to their primary controller after they have connected to a secondary controller due to the primary being offline. This ensures that once the primary WLC is back online, APs will revert to it, maintaining the intended primary/secondary controller hierarchy.
