Cisco 300-425 Online Questions & Answers

• Question 241:

  An engineer must configure the virtual IP address on multiple controllers in a mobility group. Which rule must the engineer follows to ensure proper roaming?

  A. Ensure that the DNS entry is tied to the virtual IP address of the WLC.
  B. Use a unique IP address for each WLC.
  C. Ensure that the DNS Host Name field is defined.
  D. Use the same IP address for each WLC.
  D. Use the same IP address for each WLC.

  In a mobility group, multiple controllers should be configured with the same virtual IP address to ensure proper roaming. This virtual IP address is used by wireless clients during the roaming process to facilitate seamless mobility between controllers.

• Question 242:

  In a hospital environment with many medical devices, which design consideration is most important?

  A. Using DFS channels
  B. Ensuring minimal RF interference
  C. Enabling 160 MHz channels
  D. Maximizing AP transmit power
  B. Ensuring minimal RF interference

• Question 243:

  An engineer must design a predictive site survey. The wireless network must be "location-ready". Each floor is quite small and has only a few offices. Which approach must be considered?

  A. At least two access points are deployed on each floor
  B. At least one access points are deployed on each floor.
  C. At least three access points are deployed on each floor.
  D. At least four access points are deployed on each floor.
  C. At least three access points are deployed on each floor.

• Question 244:

  Which band provides the best balance between range and throughput for enterprise WLANs?

  A. 2.4 GHz only
  B. 5 GHz
  C. 900 MHz
  D. 60 GHz
  B. 5 GHz

• Question 245:

  An engineer must identify the network requirements for a company that has a main office and 10 branch offices. The network must be able to support data, voice, video, and location tracking. Which two factors must be considered? (Choose two.)

  A. security policy of the company for building access
  B. number of wireless devices that require access
  C. type of site for which the survey will be performed
  D. available power sockets in the IT room
  E. business type of the company
  B. number of wireless devices that require access
  C. type of site for which the survey will be performed

• Question 246:

  An engineer as performing a Layer 1 passive wireless site survey utilizing a channel analyzer software in the 2.4 GHz spectrum. Which chart indicates the ratio of interference present during the duration of the capture?

  

  A. Option A
  B. Option B
  C. Option C
  C. Option C

  ---

  In a Layer 1 passive wireless site survey, the chart that indicates the ratio of interference present during the duration of the capture in the 2.4 GHz spectrum is typically a Duty Cycle chart or an Interference chart. These charts display the percentage of time that energy, possibly from interfering sources, is present on a channel. The correct answer would show fluctuations in signal levels over time, highlighting periods where interference might be affecting the channel's clarity.

• Question 247:

  Campus users report a poor wireless experience. An engineer investigating the issue notices that in high-density areas, the wireless clients fail to switch the AP to which are automatically connected. This sticky client behavior is causing roaming issues. Which feature must the engineer configure?

  A. Load balancing and band select
  B. optimized roaming
  C. Layer 3 roaming
  D. Layer 2 roaming
  B. optimized roaming

  ---

  Optimized roaming is a feature that helps mitigate sticky client behavior by assessing the client's signal strength and proactively disconnecting clients with a signal below a predefined threshold. This encourages clients to connect to a closer AP with a stronger signal, improving the overall wireless experience in high-density areas. https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/80/hdx_final/b_hdx_dg _final/high_density_experience_features_added_in_release_8_0.html

• Question 248:

  Which feature provides clients with neighbor reports to improve roaming decisions?

  A. 802.11r
  B. 802.11k
  C. 802.11d
  D. 802.11h
  B. 802.11k

• Question 249:

  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. Band Select
  B. RRM
  C. Cisco Centralized Key Management
  D. load balancing
  A. Band Select

  ---

  Band Select is a feature on Cisco WLCs that encourages dual-band capable clients to connect to the less congested 5 GHz spectrum. It works by delaying the response to clients' probes on the 2.4 GHz band, making the 5 GHz band more attractive to the client devices.

• Question 250:

  An engineer is performing an AP-on-a-stick survey and finds that the 5 GHz channel overlap is too high when an appropriate number of APs are used for the density requirements. Which two actions during the survey reduce channel overlap? (Choose two.)

  A. Raise the minimum data rate to 24 Mbps.
  B. Increase AP transmit power to improve the SNR.
  C. Allow the use of UNII-2e channels.
  D. Use directional antennas to limit the coverage area of some APs.
  E. Enable power saving mode.
  C. Allow the use of UNII-2e channels.
  D. Use directional antennas to limit the coverage area of some APs.
