Cisco 300-425 Online Questions & Answers

• Question 1:

  Which CLI command does an engineer use to validate that the redundancy peer of a Stateful Switchover pair of controllers is up and connected?

  A. rping
  B. ping
  C. eping
  D. mping
  A. rping

  ---

  Explanation Explanation/Reference:rping - Check IPsec status on both controllers to check which link is broken RP or RMI. Perform rping on both controllers to check if the peer is reachable. mping - Mobility ping over UDP--Thistest runs over mobility UDPport 16666. It tests whether the mobility control packet can be reached over the management interface. eping - Mobility ping over EoIP--This test runs over EoIP (IP protocol 97). It tests the mobility data traffic over the management interface https://www.cisco.com/c/en/us/td/docs/wireless/controller/7-6/configuration-guide/b_cg76/b_cg76_chapter_010010010.pdf https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-8/config-guide/b_cg88/high_availability.html

• Question 2:

  An engineer is using a Cisco AIR-2702i AP to conduct a Layer 1 site Survey, which mode is selected for the AP to discover non-Wi-Fi interference with metageek chanalyzer?

  A. FlexConnect
  B. Sniffer
  C. Monitor
  D. SE-connect
  D. SE-connect

  ---

  SE-Connect Mode enables a user to connect Chanalyzer directly to a Cisco CleanAir access point when the access point is not connected to a controller. The access point provides air quality and interference detection reports for all monitored channels.

• Question 3:

  An engineer Is trying to determine the most cost-effective way to deploy high availability for a campus enterprise wireless network that currently leverages three wireless LAN controllers. Which architecture should the engineer deploy?

  A. N+1 solution without SS0
  B. N+1 with SSO
  C. N+N solution without SSO
  D. N+N with SSO
  B. N+1 with SSO

  ---

  For a cost-effective high availability deployment in a campus enterprise wireless network with three controllers, the N+1 architecture with Stateful Switch Over (SSO) is recommended. This architecture provides redundancy and allows for seamless failover without service interruption, ensuring that the network remains highly available without the need for a one-to-one controller redundancy, which would be less cost-effective https://www.cisco.com/c/en/us/td/docs/wireless/ technology/hi_avail/N1_High_Availability_D eployment_Guide/N1_HA_Overview.html?

• Question 4:

  WLC SSO is set up between two WLCs in a service provider network serving public spaces. On WLC failover, it is noticed that only about half of the original client count is now showing on the secondary WLC, although it is currently showing the role as active. Which design side case explains the issue?

  A. The secondary WLC platform does not support the required client count.
  B. The WLCs had not completed database sync before the primary failure.
  C. SSO is not configured correctly.
  D. Some client sessions were in WebAuth-Req state before failover.
  D. Some client sessions were in WebAuth-Req state before failover.

  ---

  Only clients that are in Run state are synced between the Active and Standby WLC. Client SSO does not support seamless transitions for clients that are in the process of associating/joining the controller. The clients in the transition phase will be de-authenticated after switchover and will need to rejoin the controller. no deatails about the WLC status in public spaces. in that case we assume that there is no issue with the connetivity between WLCs Round trip latency on Redundancy Link should be less than or equal to 80 milliseconds. Preferred MTU on Redundancy Link is 1500 or above. Bandwidth on Redundancy Link should be 60 Mbps or more.

• Question 5:

  After the completion of a site survey with Ekahau Site Survey tool, using the default color palette, it is noted that multiple areas are shown as white on the heat map when viewing 5 GHz signal strength data. What does this indicate about the signal strength?

  A. The area is below -67 dBm at coverage cell edge.
  B. The area is below -100 dBm at coverage cell edge.
  C. The area is below the minimum threshold configured on the tool.
  D. The area is below the detectable level and indicates no RF signal.
  D. The area is below the detectable level and indicates no RF signal.

• Question 6:

  Why is 802.11a connectivity reduced in an X-ray room?

  A. X-rays create significant non-Wi-Fi interference on the 802.11a band.
  B. X-rays impact the 802,11a UNll-2 channels that cause access points to dynamically change channels.
  C. X-rays within these rooms cause multipath issues.
  D. X-ray rooms exhibit increased signal attenuation.
  D. X-ray rooms exhibit increased signal attenuation.

  ---

  The connectivity of 802.11a, which operates in the 5 GHz band, is reduced in X-ray rooms primarily due to the increased signal attenuation caused by the lead and other dense materials used in the construction of these rooms to shield against X-ray radiation. These materials effectively block or weaken the radio signals used for wireless communication portable X-ray machines, sending high-resolution images, sometimes in real time, echography machines, and electrocardiography [ECG] machines). These devices may also use the same spectrum as Wi-Fi but with other protocols and, therefore, become sources of interference for your system.

• Question 7:

  Which three pieces of equipment are needed to conduct a fully measured wireless survey? (Choose three.)

  A. PoE battery
  B. spirit level
  C. access point
  D. tall tripod
  E. goggles
  F. ladder
  A. PoE battery
  C. access point
  D. tall tripod

• Question 8:

  An engineer must design a WLAN that can handle voice traffic and location-based services. Which two design features enable both services to function properly? (Choose two.)

  A. Use every channel possible in 5 GHz.
  B. Put APs in corners of each floor for triangulation.
  C. Have a 15% overlap of cell coverage.
  D. Use every channel possible in 2.4 GHz.
  E. Have a 25% overlap of cell coverage.
  C. Have a 15% overlap of cell coverage.
  E. Have a 25% overlap of cell coverage.

• Question 9:

  A Cisco controller-based wireless network must support workgroup bridges. The APs configured as workgroup bridges must support wired and wireless clients. The wireless clients must connect to the spare radio. What is the maximum number of wired client connections supported on a workgroup bridge?

  A. 20
  B. 25
  C. 30
  D. 35
  A. 20

  ---

  Typically, a Cisco workgroup bridge can support up to 20 wired client connections. This allows for a reasonable number of devices to be connected while maintaining performance.

• Question 10:

  An engineer is configuring a centralized set of controllers for separate facilities. Which two Cisco wireless architectures must be used to ensure flexible sizing of WLAN to VLAN mappings? (Choose two.)

  A. interface group
  B. mobility group
  C. AP group
  D. controller group
  E. RF group
  A. interface group
  C. AP group

  ---

  Interface groups allow for flexible WLAN to VLAN mappings by grouping multiple interfaces into a single entity. This enables a single WLAN to be mapped to multiple VLANs, providing scalability and flexibility in network design. AP groups are used to manage the configuration of multiple APs collectively, allowing for consistent WLAN to VLAN mappings across different APs in separate facilities.
