Cisco CCNP Enterprise 300-425 Questions & Answers

• Question 71:

  Refer to the exhibit.

  

  Client A is roaming from AP1 on WLC1 to AP2 on WLC2. The client roams between two APs registered to two different controllers. The WLAN on the two controllers is on a different subnet. Which scenario explains the client's roaming behavior?

  A. The client database entry is different than that of Layer 2 roam. (Instead of copying, it moves the database to the new controller.)

  B. The client database entry is different than that of Layer 2 roam. (Instead of moving, it copies the database to the new controller.)

  C. The client database entry is different than that of Layer 2 roam because the client database is neither moved nor copied into the new controller.

  D. The client database remains in the mobility anchor controller and it is not copied or moved.

  Correct Answer: B

• Question 72:

  An engineer must deploy a wireless network in an open-plan environment that has three SSIDs using the 5 GHz band and the channel width is set to 40 MHz. Co-channel interference must be reduced. Which two actions must be taken? (Choose two.)

  A. Increase the number of SSIDs.

  B. Increase channel bonding in the 2.4 GHz band to 40 MHz.

  C. Disable band steering.

  D. Decrease channel bonding in the 5 GHz band to 20 MHz.

  E. Reduce the power of the AP.

  Correct Answer: DE

• Question 73:

  A network consultant must create a wireless design with these characteristics:

  Provide coverage in a single contiguous space.

  Support dual-band wireless coverage.

  Use nine APs for full coverage in a 5 GHz band.

  What must the engineer do to mitigate co-channel interference and maintain coverage in 2.4 GHz?

  A. Adjust the TPC neighbor threshold value to -64 dBm on the 2.4 GHz band.

  B. Configure static channel and power settings of the 2.4 GHz radios.

  C. Disable 2.4 GHz radios on selective APs.

  D. Deactivate low data rates on the 2.4 GHz band.

  Correct Answer: B

• Question 77:

  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

  Correct Answer: B

• Question 78:

  A. interface throughput

  B. high availability

  C. collision domains

  D. output power

  Correct Answer: A

• Question 79:

  What is the wireless signal loss of large cases of liquid materials being stored in a warehouse environment?

  A. It is higher than dry goods.

  B. It is not impactful to the RF design.

  C. It is less than dry goods.

  D. It is impactful but overall negligible to the RF design.

  Correct Answer: A

• Question 80:

  An engineer is trying to configure the APs installed in a new auditorium to use 40 MHz channels with high data rates and lower TX power. The APs in the building hallway must use lower-density design settings configured for the rest of the building. Which two configurations achieve this design? (Choose two.)

  A. TPC

  B. DCA

  C. AP group

  D. RRM

  E. RF profile

  Correct Answer: CE
