Certified Wireless Design Professional - CWDP-302 Exam Practice Test

Question 1

You are on site, planning a network at a freight shipping company on a busy harbor. Since the preliminary WLAN design specifies support for the 5 GHz spectrum, you would like to test for radar pulses to determine if DFS channels should be supported at this facility. As a part of your spectral survey with a laptop-based analyzer, you include DFS testing to identify the presence of radar. This is done by manually observing Real-time FFT, Duty Cycle, and Active Devices charts of the spectrum analyzer software.
What potential drawback is present with this DFS test method?

A. Modern spectrum analyzer adapters do not provide the necessary bandwidth resolution required to detect and measure radar signatures.

B. Many WLAN products that support DFS channels report several false positives. Ideally, the actual WLAN equipment used in the deployment should be used to test for DFS.

C. Manual identification of radar pulses using spectrum analysis charts can be very difficult due to radar's low amplitude at the Wi-Fi receiver.

D. Some sources of 5 GHz radar, such as military ships, are mobile in nature. A longer, automated test setup should be used to identify the presence or absence of radar.

Correct Answer: C

Question 2

What should always be done before connecting an AP to the production network?

A. Increase in output power.

B. Baseline configuration that prevents the introduction of security issues to the network on initial connection.

C. Disabling SSID broadcasting.

D. Reduction of output power.

Correct Answer: B

Question 3

You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users frequently come and go. With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client Layer 3 connections. The DHCP server is a Windows Server 2012 R2 machine. Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.
What setting would be most effective at achieving this design task?

A. Set the RTS threshold to 2346 bytes

B. Set the DHCP lease for this pool to 20 minutes

C. Set the inactive wireless client timeout (client age-out) to 5 minutes

D. Set the maximum client limit per radio to 64

Correct Answer: B

Question 4

In a manufacturing facility with highly reflective materials, you are planning an upgrade to your existing
802.11b WLAN implementation. You have chosen a dual-band 802.11n infrastructure product for this purpose. Your client applications include:
* Handheld scanners - for inventory management
* Toughbooks (laptops) - mounted on forklifts for inventory and workflow management
* VoWiFi phones - used by select employees throughout the facility
You are evaluating all of the 802.11n enhancements and determining which features to enable for your environment and applications.
In this scenario, what 802.11n enhancement typically should NOT be enabled on the 2.4 GHz radio of the new APs?

A. Frame aggregation

B. Short guard intervals

C. Multiple streams

D. Block Acknowledgments

Correct Answer: B

Question 5

What are some advantages of designing guest access with all guest users tunneled directly into the DMZ?

A. Enhances performance of web proxy servers in the DMZ for guest Internet traffic

B. Allows a single SSID with different authentication/encryption models to be used for all WLAN services for corporate users and guests

C. The border firewall configuration will not require any additional rules to pass guest traffic to the DMZ controller

D. Minimizes configuration requirements for segmentation and filtering of guest traffic across internal LAN

Correct Answer: D

Question 6

You are performing a WLAN analysis process wherein you move through the environment and actively send and receive data to and from the AP and network. The statistics are gathered including throughput rates.
What kind of process is being performed?

A. Passive Site Survey

B. Spectrum analysis

C. Active Site Survey

D. Protocol capture

Correct Answer: C

Question 7

What document might specify that RF propagation patterns, AP locations and configurations, and potential sources should be documented?

A. Hold harmless

B. Site survey deliverables

C. Project charter

D. NDA

Correct Answer: C

Question 8

You must determine the SNR of a particular signal. You know the RSSI.
What additional metric is required?

A. CCI ratio

B. Throughput rate

C. Noise floor

D. Data rate

Correct Answer: C
