CWDP-304 Online Practice Questions and Answers

A signal passes through a 10-meter cable, an amplifier, and then a filter. The amplifier has an output that is eight times higher in power than its input. Each meter of cable reduces the signal level by a factor of 4. The filter has a loss of 5 dB.

What is the total loss/gain of the three elements in series?

Response:

A. 65 dB loss

B. 16 dB gain

C. 56 dB loss

D. 37 dB loss

An engineering firm just upgraded their WLAN form nine 802.11n APS to nine 802.11ac APs. After this upgrade, they did not see any improvement in throughput. What is the most likely cause of this result?

A. APs are transmitting at a low transmit power

B. The clients were not upgraded

C. APs are mounted on the wall

D. The APs are still using the 5 GHz lower band

What operational plane would a WNMS primarily interact with?

Response:

A. Integration

B. Management

C. Control

D. Data

E. Distribution

An associated STA detects a new BSS with the same SSID as the STA's current BSS. The new BSS uses a different IP subnet than the current BSS. If the STA is configured to use 802.1X/EAP preauthentication, what is likely to occur?

A. The STA will not attempt to preauthenticate because the new BSS uses a different IP subnet.

B. The STA will attempt to preauthenticate, but fail because the new BSS uses a different data-link broadcast domain.

C. The STA will attempt to preauthenticate and succeed if DHCP is supported on the new subnet.

D. The STA will attempt to preauthenticate and succeed if IP Mobility is enabled on the AP or WLAN controller.

While performing a validation site survey, you realize that overlapping channels are being used on the 2.4 GHz bad due to the automatic channel assignment algorithm of the WLAN infrastructure. What should you do to prevent this?

A. Reconfigure the automatic channel assignment settings to use only channels 1, 6, and

B. Purchase and deploy new APs from a different vendor

C. Reconfigure the network to use static channel plans because automatic channel assignment algorithms are all broken

D. Leave it as it is; sometimes using all 11 channels in 2.4 GHz gives the optimum performance result

Which DHCP option, when required, should be configured and enabled to help APs locate their wireless LAN controller?

A. 150

B. 62

C. 43

D. 22

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. Multiple streams

B. Short guard intervals

C. Block Acknowledgments

D. Frame aggregation

You are creating an outdoor bridge link that spans more than 1000 yards. Which one of the following antenna types is more likely to be included in the design?

A. Yagi

B. Omni

C. Patch

D. Panel

During lunch time in the break room of a company, Wi-Fi connectivity on the 2.4 GHz band is intermittent. Every other time of the day, it works fine.

What's the likely cause of this issue?

A. Employees are using their cell data instead of using the Wi-Fi

B. The AP in the cafeteria keeps rebooting due to lack of PoE budget on the switch

C. Toasters and ovens are heating up the air, raising the noise floor with the Wi-Fi on the 2.4 Ghz band

D. Microwaves in the cafeteria are interfering with the Wi-Fi on the 2.4 GHz band

What two 802.11 amendments deal with regulatory and transmission requirements? Response:

B. 802.11i

C. 802.11d

D. 802.11f

E. 802.11h
