Cisco 300-425 Online Practice Questions and Exam Preparation

Cisco 300-425 Online Questions & Answers

• Question 161:

  Where must the APs be mounted when used in a high-density wireless network to provide 6 dB to 20 dB of attenuation to a cell?

  A. in the aisle
  B. under the seat
  C. above the stage
  D. under the stage
  B. under the seat

  ---

  In high-density environments, such as stadiums or auditoriums, APs are often mounted under the seats to provide a controlled cell size with attenuation. This placement helps to manage the RF environment by providing attenuation of 6 dB to 20 dB, which can reduce co-channel interference and improve the user experience by ensuring a strong signal and minimizing noise from other cells.

• Question 162:

  A retail chain wants centralized WLAN control with remote APs.

  Which Cisco deployment model is most suitable?

  A. FlexConnect
  B. Cloud-only deployment
  C. Autonomous AP deployment
  D. Mesh-only architecture
  A. FlexConnect

• Question 163:

  A wireless engineer is utilizing the voice readiness tool in Cisco Prime for a customer that wants to deploy Cisco IP phones. Which dBm range is the network inspected against?

  A. -78 to-65 dBm
  B. -72 to-67 dBm
  C. -85 to-65 dBm
  D. -85 to-67 dBm
  B. -72 to-67 dBm

  ---

  The voice readiness tool in Cisco Prime inspects the network against a dBm range that is suitable for voice over Wi-Fi. The range of -72 to -67 dBm is considered optimal for voice applications, ensuring clear audio quality and minimal packet loss. https://www.cisco.com/c/en/us/td/docs/net_mgmt/prime/infrastructure/34/user/guide/bk_CiscoPrimeInfrastructure_3_4_0_UserGuide/bk_CiscoPrimeInfrastructure_3_4_0_UserGuide_ chapter_01010.html

• Question 164:

  A customer uses a Cisco Catalyst 9800 Series wireless controller to manage all of the APs for a campus network. Secure guest access is required for the guest network. A Cisco 5520 anchor controller is deployed within a DMZ. Which design approach ensures that the mobility tunnel is established successfully between the wireless controller and the anchor controller?

  A. Run an Inter-Release Controller Mobility compatible software version on the wireless controller.
  B. Enable control plane encryption on the wireless controller.
  C. Disable data link encryption on the anchor controller.
  D. Run an Inter-Release Controller Mobility compatible software version on the anchor controller.
  D. Run an Inter-Release Controller Mobility compatible software version on the anchor controller.

• Question 165:

  During a wireless site survey for a hospital, the client requires seamless roaming for VoWi- Fi handsets.

  Which design factor is most critical to ensure high-quality voice roaming?

  A. Using omni-directional antennas for all APs
  B. Ensuring 15?0% cell overlap at ?7 dBm
  C. Deploying APs only on the 2.4 GHz band
  D. Using high-gain directional antennas in hallways
  A. Using omni-directional antennas for all APs

• Question 166:

  A high-density wireless network is designed. Which Cisco WLC configuration setting must be incorporated in the design to encourage clients to use the 5 GHz spectrum?

  A. RRM
  B. Cisco centralized key management
  C. Band select
  D. Load balancing
  C. Band select

• Question 167:

  An IT administrator is trying to establish the criteria for a predictive coverage design. The environment is a mix of 802.11g data and voice. Which minimum coverage with SNR 25 aligns with Cisco best practice?

  A. RSSI of -75dBm. 20 to 25% intercell overlap
  B. RSSI of -80dBm. 10% intercell overlap
  C. RSSI of -72dBm. 11% intercell overlap
  D. RSSI of -67dBm. 15 to 20% intercell overlap
  D. RSSI of -67dBm. 15 to 20% intercell overlap

• Question 168:

  A customer uses a Cisco 5520 WLC that is connected via a single 10-GB interface to manage the wireless network. The wireless network includes 500 APs for the campus network. The customer wants to add 300 APs and is concerned about traffic load and lack of redundancy. The purchase of a second controller is not an option. Which design approach mitigates the customer concerns?

  A. Connect a second 10-GB interface on the WLC and set the port as a secondary port.
  B. Connect a second 10-GB interface on the WLC and implement LAG.
  C. Implement a vWLC and configure SSO with the WLC.
  D. Implement a vWLC and configure N+1 redundancy with the WLC.
  B. Connect a second 10-GB interface on the WLC and implement LAG.

  ---

  The Cisco 5520 WLC supports Link Aggregation (LAG), which allows multiple physical interfaces to be treated as a single logical channel. By connecting a second 10-GB interface and implementing LAG, the customer can increase the throughput capacity and provide redundancy without the need for a second controller. This approach also simplifies network design and management by reducing the number of IP addresses needed for the controllers and APs.

• Question 169:

  As part of a wireless site survey in a hospital, an engineer needs to identify potential Layer 1 interferers. In which two areas is the engineer most likely to find sources of 2.4 GHz and 5 GHz RF noise? (Choose two.)

  A. magnetic resonance imaging
  B. kitchen
  C. Gamma Knife radiation treatment
  D. X-ray radiography
  E. patient room
  B. kitchen
  E. patient room

  B. For different SSIDs, use different VLAN IDs and subnets on both WLCs.
  C. For different SSIDs, use the same VLAN IDs and subnets on both WLCs.
  D. For the same SSIDs, use different VLAN IDs and subnets on both WLCs.
  A. For the same SSIDs, use the same VLAN IDs and subnets on both WLCs.
