Cisco 300-425 Online Questions & Answers

• Question 151:

  The wireless team must configure a new voice SSID for optimized roaming across multiple WLCs with Cisco 8821 phones. Which two settings accomplish this goal? (Choose two.)

  A. Configure mobility groups between WLCs.
  B. Use Cisco Centralized Key Management for authentication.
  C. Configure AP groups between WLCs.
  D. Configure AVC profile on new SSID.
  E. Use AVC to tag traffic voice traffic as best effort.
  B. Use Cisco Centralized Key Management for authentication.
  E. Use AVC to tag traffic voice traffic as best effort.

  Cisco 8821 phones are clients that support CCKM. CCKM caches clients' PMK for 1 hour (good for voice calls) and works inter-controller, but this require that the WLCs know each other: Mobility Group

• Question 152:

  A university lecture hall has a Cisco wireless high-density network with this configuration:

  5 GHz only 20-MHz channels UNII-1, UNII-2, and UNII2-E channels TPC minimum = 8 TPC maximum = 14

  The lecture hall is 200 feet by 100 feet and has 16 Cisco APs that use directional antennas. Which feature must be included in the design to mitigate and reduce high-channel utilization from rogue APs?

  A. band select
  B. DFS detection
  C. RxSOP
  D. 802.11w
  C. RxSOP

  ---

  Receiver Start of Packet Detection Threshold (RxSOP) helps to mitigate high-channel utilization by ignoring rogue APs and other RF interference sources. By adjusting the RxSOP threshold, APs can be made less sensitive to unwanted signals, thus reducing the impact of interference.

• Question 153:

  What is the main goal of Radio Resource Management (RRM) in Cisco WLANs?

  A. To manually configure AP channels
  B. To automatically adjust channel, power, and coverage parameters
  C. To increase antenna gain
  D. To manage client roaming decisions directly
  B. To automatically adjust channel, power, and coverage parameters

• Question 154:

  A customer is concerned about mesh backhaul link security. Which level of encryption does the backhaul link use?

  A. hash
  B. AES
  C. WEP
  D. 3DES
  B. AES

  ---

  The mesh backhaul link uses Advanced Encryption Standard (AES) for encryption. AES is a robust encryption standard that is widely used in various security protocols, including WPA2 and WPA3, to provide a high level of security for wireless communications. It ensures that the data transmitted over the mesh backhaul link is protected against unauthorized access and eavesdropping.

• Question 155:

  Multiple WLCs are implemented in a high-availability configuration in a mobility group. APs are deployed with only a primary controller assigned. By default, which mobility group member controller do the orphaned APs join in the event of a failed controller?

  A. controller with the most available AP free license capacity
  B. controller with the lowest percent of associated APs per license capacity
  C. controller with the least CPU utilization over the last reporting period
  D. controller with the least number of associated APs
  A. controller with the most available AP free license capacity

• Question 156:

  A customer has a Cisco wireless network that has these configurations and components:

  1.

  two Cisco Catalyst 9800 Series WLCs in a high availability cluster

  2.

  50 Cisco 2800I APs

  3.

  all SSIDs and services are 5 GHz only

  A security mandate requires that rogue APs be scanned and identified in 2.4 GHz and 5 GHz bands and must not impact existing client connectivity. How must the wireless network be reconfigured to meet the requirement without purchasing additional APs?

  A. Set the XOR radio role to Client Serving and the slot 1 radio to Sniffer mode on all the APs.
  B. Set the XOR radio role to Monitor mode and the slot 1 radio to Client Serving on all the APs.
  C. Set the XOR radio role to Client Serving and the slot 1 radio to Monitor mode on all the APs.
  D. Set the XOR radio role to Sniffer mode and the slot 1 radio to Client Serving on all the APs.
  B. Set the XOR radio role to Monitor mode and the slot 1 radio to Client Serving on all the APs.

• Question 157:

  A university is in the process of designing a wireless network in an auditorium that seats 500 students and supports student laptops. Which design methodology should the university implement in the auditorium?

  A. roaming design model
  B. voice design model
  C. location design model
  D. high-density design model
  D. high-density design model

  ---

  In an auditorium seating 500 students with laptops, a high-density design model is appropriate. This model focuses on supporting a large number of devices in a concentrated area with sufficient coverage and bandwidth. It involves strategic AP placement, proper channel planning, and capacity planning to ensure all students have reliable wireless access.

• Question 158:

  Which feature ensures seamless roaming between APs with no noticeable delay for voice clients?

  A. Client load balancing
  B. 802.11k
  C. 802.11r Fast Transition
  D. 802.11d
  C. 802.11r Fast Transition

• Question 159:

  What is the recommended cell overlap when designing a wireless network for Cisco Hyperlocation?

  A. 20%
  B. 30%
  C. 40%
  D. 50%
  A. 20%
