Cisco 300-425 Online Questions & Answers

• Question 71:

  An engineer has designed an anchor redundancy for guest clients connecting to SSID with auto-anchor configured. After adding a second Anchor WLC under the SSID mobility anchor list, clients are load-balanced between existing and new anchors instead of having one anchor as active and the other one as standby.

  Which feature should be included in the design that will be configured on the WLC running 8.1 or above to ensure anchor redundancy?

  A. Auto-Anchor Foreign Mapping
  B. AP groups
  C. Guest Anchor Priority
  D. 802.11r
  C. Guest Anchor Priority

  ---

  When designing anchor redundancy for guest clients with auto-anchor configured on a WLC running version 8.1 or above, setting up Guest Anchor Priority ensures that one anchor is treated as active while another acts as standby rather than load-balancing clients between anchors which is not desired in this case.

• Question 72:

  During a wireless network design, a customer requires wireless coverage on the perimeter of a building but also wants to minimize signal leakage from the wireless network. Which antenna should be used to accomplish this design?

  A. Patch
  B. Dipole
  C. Monopole
  D. Omnidirectional
  A. Patch

  ---

  A Patch antenna should be used to provide wireless coverage on the perimeter of a building while minimizing signal leakage. Patch antennas have a directional radiation pattern that can be focused along the perimeter. https://www.cisco.com/ c/en/us/td/docs/routers/connectedgrid/antennas/installing-combined/industrial-routers-and-industrial-wireless-antenna-guide/ANT-MP-INT-OUT- M.html

• Question 73:

  Refer to the exhibit.

  

  A WLC SSO pair is set up. Which failure scenario causes a split-brain scenario?

  A. RP is down.
  B. Two distribution ports on the active WLC are down.
  C. VSL is down.
  D. One distribution port on the active WLC is down.
  C. VSL is down.

  ---

  The Virtual Switching Link (VSL) is essential for communication between the active and standby Wireless LAN Controllers (WLCs) in a Stateful Switch Over (SSO) setup. If the VSL goes down, it can lead to a split-brain scenario where both WLCs assume they are active, causing network disruptions and inconsistencies in client handling.

• Question 74:

  A wireless deployment in a high-density environment is being used by vendors to process credit card payment transactions via handheld mobile scanners. The scanners are having problems roaming between access points in the environment. Which feature on the wireless controller should have been incorporated in the design?

  A. RX SOP
  B. 802.11w
  C. AP Heartbeat Timeout
  D. Application Visibility Control
  A. RX SOP

• Question 75:

  A customer has multiple WGBs located around a warehouse to support mobile and stationary industrial machines. The wireless network consists of these components:

  1.

  two Cisco 5520 WLCs in a high availability cluster

  2.

  100 Cisco 2800 APs in local mode

  3.

  25 Cisco IW3700 Series APs in WGB mode

  4.

  WLANs that are all 802.11a only

  5.

  UNII 1, UNII 2, and UNII 2E channels in use

  The customer wants to use only UNII 2 channels within the mobile machine area of the warehouse and must reduce the channel scan time on the WGBs. Which channels must be incorporated in the design for the WGBs?

  A. 36, 40, 44, 48
  B. 52, 56, 60, 64
  C. 100, 104, 108, 112
  D. 149, 153, 157, 161
  B. 52, 56, 60, 64

• Question 76:

  When conducting a site survey for real-time traffic over wireless, which two design capabilities of smartphones and tablets must be considered? (Choose two.)

  A. no support for 802.11ac
  B. higher data rates than laptops
  C. fewer antennas than laptops
  D. no support for 802.11r
  E. lower data rates than laptops
  C. fewer antennas than laptops
  E. lower data rates than laptops

  ---

  Smartphones and tablets typically have fewer antennas than laptops, which can affect their signal reception and transmission capabilities. Additionally, they often support lower data rates compared to laptops due to their smaller size and power constraints.

• Question 77:

  An engineer must perform a predictive design for a wireless network for location readiness and to mitigate interference. Which power level does the engineer use?

  A. 10 mw
  B. 18 mw
  C. 20 mw
  D. 50 mw
  B. 18 mw

  ---

  For predictive designs, especially for location readiness and interference mitigation, a mid-range power level like 18 mw is often used. It provides a balance between coverage and minimizing interference with other devices and networks.

• Question 78:

  How are mobility groups created, excluding mobility anchors?

  A. The WLCs do not have to be of the same model or type to be a member of a mobility group; however, each member should be running different software versions.
  B. A mobility group does not require all WLCs in the group to use the same virtual IP address.
  C. Each WLC must use the same mobility domain name and be defined as a peer in each other's static mobility members list.
  D. If WLCs with HA SSO are deployed, each WLC in the WLC HA pair is considered separately as a mobility peer.
  D. If WLCs with HA SSO are deployed, each WLC in the WLC HA pair is considered separately as a mobility peer.

• Question 79:

  An engineer must create a multicampus architecture wireless design to accommodate 4500 access points for wireless data and guest access. Which model controller fits the requirements to support all access points on one high availability controller setup?

  A. 3504
  B. 5508
  C. 5520
  D. 8540
  D. 8540

  ---

  The Cisco 8540 Wireless Controller is designed for large enterprise and high-density environments. It has the capacity to manage up to 6000 access points, making it suitable for a multicampus architecture that needs to accommodate 4500 access points. Its high availability features ensure that all access points can be supported on one controller setup with minimal downtime.

• Question 80:

  A wireless network consultant must assess an existing wireless LAN controller. Which section must the consultant check before replacing the old APs with APs that are IEEE 802.11ac-capable?

  A. number of AP licenses
  B. controller PSU
  C. throughput capacity
  D. software version
  D. software version

  ---

  Before replacing old APs with IEEE 802.11ac-capable APs, it is crucial to check the software version of the wireless LAN controller. The controller's firmware must support the newer standards and capabilities of 802.11ac APs. An outdated software version may not support the advanced features and performance enhancements offered by 802.11ac technology, leading to compatibility issues and suboptimal network performance.
