Cisco 300-425 Online Questions & Answers

• Question 51:

  An enterprise network administrator is asked to set up an experimental WLAN for a collaboration project with a local service provider. The WLAN must be anchored to a WLC in the service provider data center using legacy mobility mode. After the configurations are completed on the WLCs and the firewalls in the path, the data path mobility tunnel is failing to come up. What should be performed by the administrator to debug the issue?

  A. Establish a Telnet connection from a local PC to the firewall on port 97.
  B. Use the eping command on the WLC.
  C. Establish a Telnet connection from a local PC to the firewall on port 16666.
  D. Use the mping command on the WLC.
  B. Use the eping command on the WLC.

  First lets look at the matrix https://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/113344-cuwn-ppm.html Mobility data traffic is carried via Ethernet over IP (EoIP) which is IP protocol 97 hence firewall rules should allow IP protocol 97 traffic between your WLCs.

• Question 52:

  A hospital needs seamless roaming between APs for wireless medical devices. Which WLAN feature is most critical?

  A. DFS channels
  B. Mobility groups
  C. Band Select
  D. CleanAir
  B. Mobility groups

• Question 53:

  A company is upgrading the wireless infrastructure and is in a state of transition. Some parts of the company's building still run on the legacy WLC. The new WLC is not located at the same site as the legacy WLC. The company requires seamless client inter-controller roaming between the new WLC and the legacy WLC, with no disruptions. Both WLCs are separated by firewalls. Which troubleshooting command validates that the mobility control packets between the WLCs can be sent and received?

  A. mping mobility_peer_IP_address
  B. debug mobility handoff enable
  C. debug mobility config enable
  D. eping mobility_peer_management_IP_address
  A. mping mobility_peer_IP_address

• Question 54:

  An engineer changed the TPC Power Threshold for and wireless deployment from the default value to-65 dBm. The engineer conducts a new post-deployment Survey to validate the results What is the expected outcome?

  A. Increase cell size
  B. Decreased client signal strength
  C. Increased received sensitivity
  D. Decreased channel overlap
  A. Increase cell size

• Question 55:

  An enterprise is using a Cisco AireOS controller and Wi-Fi 6 APs. The controller is installed in the head office, and the employees primarily use Apple OS devices. The APs broadcast WLAN ENT-WLAN406558520-1 for the employees and a guest WLAN with similar naming. What needs to be enabled on the controller to optimize roaming?

  A. Aggregated Probe Response Optimization
  B. Fast SSID Changing
  C. Load Balancing Window
  D. Client Timers
  B. Fast SSID Changing

• Question 56:

  What is the attenuation value of a human body on a wireless signal?

  A. 3 dB
  B. 4 dB
  C. 6 dB
  D. 12 dB
  A. 3 dB

• Question 57:

  When a wireless survey is conducted at a customer facility, signal attenuation in an area that is surrounded by thick glass walls is noted as 2dB. When Cisco Prime Infrastructure is configured, which obstacle must be placed in a map editor to represent the impact that the glass wall will have on the RF signal in the facility?

  A. heavy door
  B. glass
  C. thick wall D. light wall
  B. glass

  ---

  When configuring Cisco Prime Infrastructure, to represent the impact of a thick glass wall with an attenuation of 2dB on the RF signal, the obstacle that should be placed in the map editor is glass. This is because the material-specific attenuation values are used to model the RF signal's behavior as it passes through different types of obstacles, and the thick glass wall's impact is best represented by the glass obstacle in the map editor.

• Question 58:

  A customer is running a guest WLAN with a foreign/export-anchor setup. There is one anchor WLC in the US and two in Europe. Anchor WLC priorities are used to prefer local anchors. During a routine network audit, it is discovered that a large number of guest client sessions in the US are anchored to the WLCs in Europe. Which reason explains this behavior?

  A. The foreign WLC failed and recovered.
  B. The US anchor WLC failed and recovered.
  C. The US anchor WLC is anchored to itself with a priority value of zero.
  D. The anchor WLC is in the same mobility group.
  B. The US anchor WLC failed and recovered.

  ---

  The behavior of guest client sessions in the US being anchored to the WLCs in Europe despite the presence of a local anchor WLC can be explained by the failure and subsequent recovery of the US anchor WLC. During the failure, the guest sessions would have been transferred to the European WLCs. After recovery, if the priority settings were not correctly restored or if the system did not automatically revert back to the local anchor, the sessions would remain anchored to the European WLCs3.

• Question 59:

  Which survey type uses predictive modeling software instead of physically visiting the site?

  A. Passive survey
  B. Predictive survey
  C. Active survey
  D. Post-deployment survey

• Question 60:

  What is the maximum recommended number of SSIDs per WLAN to avoid excessive overhead?

  A. 4?
  B. 8?0
  C. 12?5
  D. 20+
  C. 12?5
