Cisco 300-425 Online Questions & Answers

• Question 271:

  A customer called with a requirement that internal clients must be on different subnets depending on the building they are in. All access points are operating in local mode and will not be modified, and this is a single controller solution. Which design approach creates the desired result?

  A. Create AP groups for each desired location, map the correct VLANs to the internal SSID, and add the access points for that location.
  B. Create an SSID place it to the desired VLAN under WLANs and configure 802.1x in ISE to assign the correct VLAN based on the SSID from which the client is authenticating
  C. Create FlexConnect groups, place the access points in, and set the correct VLAN to SSID mapping based on location.
  D. Create mobility anchors for the SSID and on the controller under the internal SSID create a foreign map to the desired VLAN based on location.
  A. Create AP groups for each desired location, map the correct VLANs to the internal SSID, and add the access points for that location.

• Question 272:

  An engineer is performing a predictive wireless design for a medical treatment environment, which requires data and voice services. What is the minimum requirement for the design?

  A. overlapping-72 dBm coverage from two access points
  B. continuous-67 dBm coverage from one access point
  C. continuous-72 dBm coverage from one access point
  D. overlapping-67 dBm coverage from two access points
  B. continuous-67 dBm coverage from one access point

  ---

  In a medical treatment environment where both data and voice services are required, continuous coverage of -67 dBm from one access point is the minimum requirement. This ensures that there is sufficient signal strength for reliable voice communication, which is critical in medical settings. The -67 dBm threshold is commonly recommended for voice applications to ensure call quality and reliability. So -67dBm covers both Data and Voice with a single AP

• Question 273:

  A customer has this wireless design:

  1.

  two Cisco Catalyst 9800 Series wireless controllers configured in a high-availability SSO cluster to manage APs in the local office network

  2.

  100 APs in local mode and registered to the high-availability cluster

  3.

  one Catalyst 9800 Series wireless controller that is deployed as an anchor in a DMZ

  4.

  Cisco ISE for user authentication and authorization

  The customer wants to deploy a new SSID to support staff BYOD devices and authenticate users via Cisco ISE. The SSID terminates on the anchor WLC. How must the requirement be incorporated into the design to address the AAA servers for the WLAN?

  A. Send the AAA server accounting and authentication traffic from the high-availability cluster.
  B. Send the AAA server accounting and authentication traffic from the anchor WLC.
  C. Send the accounting traffic from the anchor WLC and the authentication traffic from the high-availability cluster.
  D. Send the accounting traffic from the high-availability cluster and the authentication traffic from the anchor WLC.
  B. Send the AAA server accounting and authentication traffic from the anchor WLC.

• Question 274:

  Which design consideration is most important for real-time applications such as voice and video over WLAN?

  A. High data rates
  B. Low latency and jitter
  C. Maximum throughput
  D. Use of DFS channels
  B. Low latency and jitter

• Question 275:

  An engineer needs a budgetary number for the quantity of 9115AXI APs in a new conference center. The engineer plans to use only the 5 GHz band and use 20 MHz channel width. Based on this requirement and Cisco best practices, what is the amount of square feet covered per AP in a high-density conference room layout?

  A. 3,500 square feet
  B. 1.000 square feet
  C. 5,000 square feet
  D. 2,500 square feet
  D. 2,500 square feet

• Question 276:

  An engineer is designing a solution where guests terminate on an anchor controller in the DMZ. The engineer is having issues and wants to test connectivity between members of a mobility group. Which command must be issued to test whether a mobility control packet is able to be reached over the management interface?

  A. show logging
  B. mapping
  C. eping
  D. tracert
  B. mapping

• Question 277:

  An engineer is designing a wireless network for a manufacturing facility that has high steel shelves. Which antenna type must be used?

  A. outdoor omnidirectional
  B. patch
  C. indoor omnidirectional
  D. dipole
  A. outdoor omnidirectional

• Question 278:

  An engineer is designing a new wireless network for an international company. The design must have these requirements:

  1.

  broadcast wireless channels based on country regulations

  2.

  controllers to support APs for regulatory domains

  3.

  RF changes applied on APs per country that are installed

  4.

  multiple-country feature to be used on the controllers

  Which design approach must be taken?

  A. Install APs and controllers with the same license number across all offices globally.
  B. Install APs and controllers with the same part number across all offices globally.
  C. Create an RF group with controllers configured with the same set of countries in the random order.
  D. Create an RF group with controllers configured with the same set of countries in the same order.
  D. Create an RF group with controllers configured with the same set of countries in the same order.

• Question 279:

  A hospital wireless environment was designed with these characteristics:

  1.

  RF coverage

  2.

  better than -67 dBm in the 5 GHz spectrum

  3.

  RRM be used for DCA and TPC in the 2.4 GHz band

  4.

  RRM be used for DCA and TPC in the 5 GHz band

  After deployment, why do many of the legacy 802.11b/g devices have difficulty maintaining connectivity?

  A. Excessive co-channel interference in the 2.4 GHz band exists.
  B. Excessive overlapping channels in the 2.4 GHz band exists.
  C. TPC drastically increases Tx power in the 2.4 GHz band.
  D. TPC drastically reduces Tx power in the 2.4 GHz band.
  D. TPC drastically reduces Tx power in the 2.4 GHz band.

  The Cisco Aironet 3800 Series APs support mGig, which allows for higher throughput over existing cabling. However, the maximum cable length that supports 5G operation is limited by the quality of the cable and signal attenuation. Category 5e cabling can support 5G operation up to a length of 130 meters, which is within the acceptable range for maintaining the required signal integrity for 5G speeds.

• Question 280:

  A customer has a centralized wireless deployment with N+1 high availability and few open authentication SSIDs configured. After failover, all APs are broadcasting all SSIDs, but the clients are assigned IP addresses from a different subnet. The WLANs on both WLCs are configured with the same dynamic interfaces. Which feature must be incorporated in the wireless design of the second controller?

  A. RF Profile
  B. AP Groups
  C. VLAN Select
  D. AAA Override
  C. VLAN Select

  ---

  VLAN Select is a feature that allows for the assignment of clients to different VLANs based on various criteria, such as user credentials or device type. In a centralized wireless deployment with N+1 high availability, incorporating VLAN Select can ensure that clients maintain consistent IP addressing across failovers, preventing them from being assigned IP addresses from a different subnet.
