Cisco CCNP Enterprise 300-425 Questions & Answers

• Question 21:

  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.

  Correct Answer: C

• Question 22:

  An engineer must perform a predictive wireless survey to indicate the number of access points required. The engineer has created a new project and imported the floor plan. Which step must be taken next for accurate AP placement?

  A. Analyze the network.

  B. Identify the coverage area.

  C. Set the scale.

  D. Place the access points.

  Correct Answer: C

• Question 23:

  Refer to the exhibit.

  

  A company is designing a Cisco wireless solution that has two WLCs named WLC1 and WLC2 and several APs. An AP named AP12 is a critical AP and is provisioned to be installed in hallway 6, which is located just outside the office of the company director and must always connect to WLC1.

  Which priority level must be incorporated in the design for AP12?

  A. 1

  B. 2

  C. 3

  D. 4

  Correct Answer: D

• Question 24:

  An engineer must design a predictive site survey. The wireless network must be "location-ready". Each floor is quite small and has only a few offices. Which approach must be considered?

  A. At least two access points are deployed on each floor

  B. At least one access points are deployed on each floor.

  C. At least three access points are deployed on each floor.

  D. At least four access points are deployed on each floor.

  Correct Answer: C

• Question 25:

  Refer to the exhibit

  

  A wireless consultant is performing an onsite survey using AirMagnet Survey PRO. What must be configured on the floor map so that the results appear properly?

  A. Show details of the user density.

  B. Calibrate the dimensions.

  C. Display details of the desk numbers

  D. Add inter-floor bleed

  Correct Answer: B

• Question 26:

  An engineer performs a wireless site survey of a multi-floor building for 2.4-GHz and 5-GHz bands. The customer wants to identify non-802.11 sources of interference. Which survey measurement must be included in the survey?

  A. channel utilization

  B. spectrum analysis

  C. signal-to-noise ratio

  D. co-channel interference

  Correct Answer: B

• Question 27:

  An engineer is deploying new APs to serve IEEE 802.11g through 802.11ac clients and wants to use the Ekahau Site Survey tool to verify RF coverage. Management wants the engineer to verify and create coverage maps as quickly as possible. Which configuration accomplishes the goal?

  A. passive mode with two wireless adapters

  B. passive mode with one wireless adapter

  C. active mode with two wireless adapters

  D. active mode with one wireless adapter

  Correct Answer: A

• Question 28:

  An IT administrator is trying to establish the criteria for a predictive coverage design. The environment is a mix of 802.11g data and voice. Which minimum coverage with SNR 25 aligns with Cisco best practice?

  A. RSSI of -75dBm. 20 to 25% intercell overlap

  B. RSSI of -80dBm. 10% intercell overlap

  C. RSSI of -72dBm. 11% intercell overlap

  D. RSSI of -67dBm. 15 to 20% intercell overlap

  Correct Answer: D

• Question 29:

  A customer has two Cisco WLCs configured in a SSO cluster. The wireless network supports a large warehouse. The customer purchases new iPads to replace legacy scanners. Both devices connect to a single SSID named Scanning by using WPA2 Personal. The customer wants to use a standards-based method for fast roaming on the new iPads. Which approach meets the scanner requirement and still supports the legacy scanners?

  A. Enable FT PSK and set Fast Transition to Adaptive for the Scanning SSID.

  B. Enable FT 802.1X and set Fast Transition to Adaptive for the Scanning SSID.

  C. Enable optimized roaming globally and enable FT 802.1X on the Scanning SSID.

  D. Enable optimized roaming globally and enable FT PSK on the Scanning SSID.

  Correct Answer: A

• Question 30:

  An engineer added an AP to a deployment after a post-installation site survey. The engineer then notices an increase in co-channel interference and retransmissions. Which two features help mitigate the issue? (Choose two.)

  A. Cisco Compatible Extensions

  B. Transmit Power Control

  C. Enhanced Distributed Channel Access

  D. Coverage Hole Detection

  E. Dynamic Channel Assignment

  Correct Answer: BE
