Cisco 300-425 Online Questions & Answers

• Question 191:

  A company installs a new anchor controller in the DMZ. The company has not upgraded the foreign controller for several years. The foreign controller runs code 7.5. The IT administrator suggests that the company upgrade the foreign controller and the new anchor controller to 8.10 or later. Which two benefits must be incorporated into the design regarding the code upgrade? (Choose two.)

  A. The foreign controller load balances guest clients across the list of anchor controllers
  B. Guest clients are load balanced in round-robin fashion among the anchor controllers.
  C. User devices must upgrade their WLAN card drivers.
  D. Guest clients are tunneled to anchors with the highest priority.
  E. The foreign controller designates one anchor as primary and one or more anchors as secondary.
  D. Guest clients are tunneled to anchors with the highest priority.
  E. The foreign controller designates one anchor as primary and one or more anchors as secondary.

• Question 192:

  A network engineer is working on a design for a wireless network that must support data, voice, and location services. To support these services, which access point placement must the engineer use?

  A. corner only
  B. perimeter and corner
  C. perimeter only
  D. indoor and outdoor
  B. perimeter and corner

  ---

  In a location-ready design, it is important to ensure that access points are not solely clustered in the interior and toward the center of floors. Rather, perimeter access points complement access points located within floor interior areas. In addition, access points must be placed in each of the four corners of the floor, and at any other corners that are encountered along the floor perimeter. These perimeter access points play a vital role to ensure good location fidelity within the areas they encircle, and, in some cases, can provide general voice or data coverage, as well.

• Question 193:

  What is the primary purpose of a validation survey?

  A. To predict AP placement before installation
  B. To confirm that the deployed WLAN meets design requirements
  C. To simulate wireless performance using CAD drawings
  D. To test AP throughput in a lab environment
  B. To confirm that the deployed WLAN meets design requirements

• Question 194:

  An engineer has deployed a group of APs in an auditorium and notices that the APs are showing high cochannel interference. Which profile can be used to adjust the parameters for these high-density APs?

  A. QoS profile
  B. AVC profile
  C. RF profile
  D. ISE profile
  C. RF profile

  ---

  In a high-density environment like an auditorium, where APs are in close proximity and a large number of devices are connected, the RF profile is used to adjust the radio frequencies of the APs to minimize co-channel interference. The RF profile allows for the configuration of power levels, channel width, and channel assignment to optimize wireless performance and reduce interference.

• Question 195:

  How does AP failover priority for access points function when configured with priority 1 or 4?

  A. When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.
  B. When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.
  C. When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.
  D. When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.
  B. When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

• Question 196:

  A wireless engineer must assess constraints for a future WLAN deployment for a site that consists of office cubicles. Which signal propagation attenuation result is associated with this environment?

  A. reflection
  B. absorption
  C. noise
  D. refraction
  B. absorption

• Question 197:

  An engineer performs a Layer 1 survey by using Metegeek chanalyzer only on the current operating channel. Which operating mode is configured for a Cisco CleanAIR AP?

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

  ---

  In Local Mode, each Cisco CleanAir-enabled access point radio provides air quality and interference detection reports for the current operating channel only." "In Monitor Mode, the access point provides air quality and interference detection reports for all monitored channels." "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. https://support.metageek.com/hc/en-us/articles/200591105-Connecting-Chanalyzer-to-a-Cisco-CleanAir-Access-Point

• Question 198:

  An engineer is reducing the subnet size of the corporate WLAN by segmenting the VLAN into smaller subnets. Clients will be assigned a subnet by location. Which type of groups can the engineer use to map the smaller subnets to the corporate WLAN?

  A. WLC port groups
  B. RF groups
  C. AP groups
  D. interface groups
  C. AP groups

  ---

  In typical deployment scenarios, each WLAN is mapped to a single dynamic interface per WLC, but consider a deployment scenario where there is a 4404-100 WLC that supports the maximum number of APs (100). Now consider a scenario where 25 users are associated to each AP. That would result in 2500 users who share a single VLAN. Some customer designs can require substantially smaller subnet sizes. One way to deal with this is to break up the WLAN into multiple segments. The AP grouping feature of the WLC allows a single WLAN to be supported across multiple dynamic interfaces (VLANs) on the controller. This is done when a group of APs is mapped to a specific dynamic interface. APs can be grouped logically by employee workgroup or physically by location. https://www.cisco.com/c/en/us/support/docs/wireless-mobility/wireless-vlan/71477-ap-group-vlans-wlc.html

• Question 199:

  A network engineer is designing a new wireless network. The network needs to have these characteristics:

  

  Which approach should be taken?

  A. Deploy APs near each other for 5 GHz coverage, and disable the 2.4 GHz radios for some Aps.
  B. Deploy APs near each other for 2.4 GHz coverage, and disable the 5 GHz radios for all APs.
  C. Deploy APs near each other for 5 GHz coverage, and enable the 2.4 GHz radios for all Aps.
  D. Deploy APs near each other for 2.4 GHz coverage, and disable the 5 GHz radios for some APs.
  A. Deploy APs near each other for 5 GHz coverage, and disable the 2.4 GHz radios for some Aps.

  ---

  In environments with high client density, deploying APs for 5 GHz coverage is recommended due to the larger number of non-overlapping channels available, which can support higher data rates and client capacity. Disabling the 2.4 GHz radios on some APs can reduce interference and improve overall network performance. https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/86/b_Cisco_Wireless_ LAN_Controller_Configuration_Best_Practices.html

• Question 200:

  An enterprise is using two wireless controllers to support the wireless network. The data centre is located in the head office Each controller has a corporate WLAN configured with the nameCopr-NET390595865WLC-1 and CoprNET6837l638WLC-2. The APs are installed using a round-robin approach to load balance the traffic. What should be changed on the configuration to optimize roaming?

  A. Move all access points to one controller and use the other as N+1 HA.
  B. Move the controllers to an external data center with higher internet speeds.
  C. Use the same WLAN name for the corporate network on both controllers.
  D. Place the access points per floor on the same controller.
  C. Use the same WLAN name for the corporate network on both controllers.

  ---

  To optimize roaming in a wireless network with multiple controllers, it is essential to use the same WLAN name (SSID) across all controllers. This allows clients to roam seamlessly between access points managed by different controllers without having to re-authenticate or experience disconnections
