Free Cisco 300-425 Exam Dumps Questions & Answers

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.

A customer has an existing wireless network with these components:
- Cisco 9800 wireless controller high availability cluster
- Cisco 9120 APs
The customer asks an engineer to perform a post wireless survey of the current network state that includes a list of any non-802.11 devices on the 5 GHz band. The engineer performs the survey by using an 802.11a/b/g/n/ac/ax WLAN adapter but did not use a spectrum analyzer.
Which approach meets the requirements?

• A.  Export a list of 802.11b interferes using the WLC and the RF ASIC embedded in the APs.
• B.  Set the WLAN adapter to monitor mode and perform the analysis by using 802.11a.
• C.  Export a list of 802.11a interferes using the WLC and the RF ASIC embedded in the APs.
• D.  Set the WLAN adapter to monitor mode and perform the analysis by using 802.11b.

Correct Answer:

Explanation:
Link Aggregation
Link aggregation (LAG) is a partial implementation of the 802.3ad port aggregation standard. It bundles all of the controller's distribution system ports into a single 802.3ad port channel. This reduces the number of IP addresses required to configure the ports on your controller. When LAG is enabled, the system dynamically manages port redundancy and load balances access points transparently to the user.
LAG simplifies controller configuration because you no longer require to configure primary and secondary ports for each interface. If any of the controller ports fail, traffic is automatically migrated to one of the other ports. As long as at least one controller port is functioning, the system continues to operate, access points remain connected to the network, and wireless clients continue to send and receive data.

A customer with two Cisco 5520 WLCs that work as a primary and secondary had some switching issues and the primary controller lost connectivity. Immediately all APs went to discovery and joined the secondary controller. After recovering from the issue, the primary controller is online, but no APs return to it. All APs remain in the secondary controller. Which setting advises the APs to return to their primary controller?

• A.  AP multicast mode
• B.  AP fallback
• C.  broadcast forwarding
• D.  AP heartbeat timeout

A network engineer configures mobility between Cisco WLCs at the office headquarters. The wireless network includes Cisco AireOS controllers on each floor. Each controller supports the wireless clients including guests for the specific floor. The engineer must test whether the mobility is configured correctly. Which two CLI commands must the engineer use? (Choose two.)

• A.  tcpdump
• B.  topping
• C.  mping
• D.  netstat
• E.  eping
