Cisco 300-425 Online Questions & Answers

• Question 61:

  Which survey type relies on predictive models of RF behavior based on building floor plans and materials, without physically measuring signals?

  A. Active survey
  B. Passive survey
  C. Predictive survey
  D. Validation survey
  C. Predictive survey

• Question 62:

  An engineer must design AP placements for a new branch office that contains two floors. The engineer uses Ekahau to complete the predictive survey. To calculate the signal bleed through between floors, the engineer creates a building, adds the floors, and attenuations areas. After the scale is set, what else must be added on the floors to accurately measure the signal bleed at a specific location?

  A. Choose the access point models.
  B. Start the auto planner.
  C. Add alignment points.
  D. Draw in coverage areas.
  C. Add alignment points.

• Question 63:

  A network engineer is troubleshooting connectivity issues between two WLCs running 8.x code in SSO mode and finds that the redundancy management heartbeat is failing. Which packet type must be filtered for heartbeats when taking a capture to verify communication?

  A. RSTP
  B. UDP
  C. TCP
  D. ICMP
  B. UDP

  ---

  The redundancy management heartbeat in Cisco Wireless LAN Controllers (WLCs) running 8.x code in Stateful Switch Over (SSO) mode uses UDP packets for communication. When troubleshooting connectivity issues between two WLCs, it is essential to filter for UDP packets in a packet capture to verify the heartbeat communication. The heartbeat packets are sent on a specific UDP port, and filtering for this port can help isolate the heartbeat traffic from other types of traffic in the capture.

• Question 64:

  Refer to the exhibit.

  

  A network engineer has identified that during a recent controller failure, several APs failed over to the tertiary controller instead of the secondary controller. The configuration from one of the APs is provided. Which design consideration led to the issue?

  A. The secondary controller was at capacity.
  B. The secondary controller is an SSO configuration.
  C. The tertiary controller is an HA-SKU controller, so it took priority.
  D. The tertiary controller is in the same subnet as the primary controller.
  A. The secondary controller was at capacity.

  ---

  The issue where APs failed over to the tertiary controller instead of the secondary controller during a controller failure is likely due to the secondary controller being at capacity. When a controller reaches its maximum capacity, it cannot accept any additional APs, causing them to failover to the next available controller in the high availability configuration.

• Question 65:

  A medium-sized hospitality company with 50 hotels needs to upgrade the existing WLAN in each hotel to 802.11n. During the site surveys for each hotel, what needs to be taken into consideration when determining the locations for each AP?

  A. Selecting locations that are easily accessed so maintenance and upgrades can be performed quickly.
  B. Selecting AP locations where power is already available.
  C. Selecting APs that can be hidden in ceiling panels to provide a secure and clean aesthetic look.
  D. Selecting locations that make visual assessment of the AP operation easy.
  A. Selecting locations that are easily accessed so maintenance and upgrades can be performed quickly.

  ---

  When conducting site surveys for WLAN upgrades to 802.11n, it's important to consider AP locations that allow for easy access. This facilitates quick maintenance and upgrades, ensuring minimal downtime and disruption to the network. While aesthetics and power availability are also considerations, the primary focus should be on maintaining the network's performance and reliability.

• Question 66:

  A network engineer is working for an enterprise where most of the laptops support 802.11v. To optimize the client roaming experience, configuration changes must be made on the corporate SSID to force clients to use the best APs based on the 802.11 v BSS transition message. Which configuration meets this requirement?

  A. Enable BSS transition for the SSID and disable dissociation imminent to avoid client disconnects.
  B. Enable the BSS transition option with an optimized roaming timer for the corporate SSID.
  C. Enable coverage hole detection and BSS transition and disable dissociation imminent.
  D. Disable coverage hole detection and enable 802.11k for the corporate SSID.
  A. Enable BSS transition for the SSID and disable dissociation imminent to avoid client disconnects.

• Question 67:

  A shopping mall wants to track customer movement patterns using Wi-Fi. Which Cisco solution should you recommend?

  A. Cisco CleanAir
  B. Cisco DNA Spaces
  C. Cisco Band Select
  D. Cisco ClientLink
  B. Cisco DNA Spaces

• Question 68:

  Which Cisco WLC feature allows grouping of APs into a logical set for RF management?

  A. RF Profiles
  B. FlexConnect Groups
  C. Mobility Groups
  D. AP Groups
  D. AP Groups

• Question 69:

  Which wireless survey type is performed without APs installed, using simulated AP locations?

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

• Question 70:

  A customer has determined that aesthetics is a primary concern for their upcoming guest deployment. Which design consideration can be leveraged to address this concern?

  A. Paint the access point to cover the LED from being noticeable.
  B. Use enclosures to hide the wireless infrastructure in the surrounding environment.
  C. Use AIR-AP-BRACKET-1 to allow for greater mounting locations
  D. Deploy environmentally friendly cabling components to blend into the environment.
  B. Use enclosures to hide the wireless infrastructure in the surrounding environment.

  ---

  To address aesthetic concerns, using enclosures can effectively conceal wireless infrastructure, such as access points, within the environment. This helps maintain the visual appeal of the area while still providing the necessary wireless coverage.
