CWNP Wireless Network Administrator (CWNA) Sample Questions (Q102-Q107):NEW QUESTION # 102
ABC Company is planning to install a new 802.11ac WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. ABC Company has hired you to perform the RF site survey.
During the interview with the network manager, you are told that the new Ethernet edge switches will support VoIP phones and 802.11 access points, both using 802.3 PoE.
After hearing this information, what immediate concerns do you note?
  • A. VoIP phones and 802.11 access points should not be powered by the same edge switch due to distortion.
  • B. If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal locations for
    802.11 APs
  • C. The power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices.
  • D. The edge Ethernet switches should support Ether-channel to get the best results out of the network.
Answer: C
Explanation:
An immediate concern that you note after hearing this information is that the power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices. PoE stands for Power over Ethernet and is a technology that allows Ethernet switches to deliver power along with data to devices such as VoIP phones and 802.11 access points. PoE devices are classified into different classes based on their power consumption and output. The edge switches have a limited power budget that determines how many PoE devices they can support simultaneously. If the power budget is exceeded, some PoE devices may not receive enough power or may shut down unexpectedly. Therefore,it is important to plan and monitor the power budget in the edge switches based on the number and class of PoE devices connected to them. Using Ether-channel, placing switches in optimal locations, or avoiding distortion are not immediate concerns related to PoE devices.

NEW QUESTION # 103
What is always required to establish a high quality 2.4 GHz RF link at a distance of 3 miles (5 kilometers)?
  • A. Grid antennas ateach endpoint
  • B. A Fresnel Zone that is at least 60% clear of obstructions
  • C. Minimum output power level of 2 W
  • D. A minimum antenna gain of 11 dBi at both endpoints
Answer: B
Explanation:
What is always required to establish a high quality 2.4 GHz RF link at a distance of 3 miles (5 kilometers) is a Fresnel Zone that is at least 60% clear of obstructions. The Fresnel Zone is an elliptical-shaped area around the line-of-sight path between two antennas that reflects and refracts the RF waves. The Fresnel Zone radius depends on the frequency of the RF signal and the distance between the antennas. For optimal performance, the Fresnel Zone should be at least 60% clear of any obstructions that may cause interference, attenuation, or multipath fading. The minimum output power level, antenna gain, and antenna type may vary depending on the environmental conditions and regulatory constraints, but they are not always required for a high quality RF link.

NEW QUESTION # 104
You were previously onsite at XYZ's facility to conduct a pre-deployment RF site survey. The WLAN has been deployed according to your recommendations and you are onsite again to perform a post-deployment validation survey.
When performing this type of post-deployment RF site survey voice over Wi-Fi, what is an action that must be performed?
  • A. Spectrum analysis to locate and identify RF interference sources.
  • B. Frequency-band hopping analysis to detect improper RF channel implementations.
  • C. Application analysis with an active phone call on an VoWiFi handset.
  • D. Protocol analysis to discover channel use on neighboring APs.
Answer: C
Explanation:
When performing a post-deployment validation survey for voice over Wi-Fi (VoWiFi), an action that must be performed is Application analysis with an active phone call on a VoWiFi handset. Application analysis is a method of testing the performance of a specific application over the WLAN by measuring parameters such as throughput, latency, jitter, packet loss, MOS score, and R-value. Application analysis with an active phone call on a VoWiFi handset can help to evaluate the quality of service (QoS) and user experience of VoWiFi calls over the WLAN. It can also help to identify any issues or bottlenecks that may affect VoWiFi calls such as interference, roaming delays, or insufficient coverage.

NEW QUESTION # 105
You are troubleshooting a controller-based AP that is unable to locate the controller. DHCP is not use and the controller is located at 10.10.10.81/24 while the AP is on the 10.10.16.0/24 network. What should be inspected to verify proper configuration?
  • A. AP hosts file
  • B. BOOTH
  • C. DNS
  • D. NTP
Answer: C
Explanation:
What should be inspected to verify proper configuration is DNS. DNS stands for Domain Name System and is a service that resolves hostnames to IP addresses. In a controller-based AP deployment, DNS can be used to help the AP locate the controller by using a predefined hostname such as CISCO-CAPWAP-CONTROLLER or aruba-master. The AP sends a DNS query for this hostname and receives an IP address of the controller as a response. Therefore, if DNS is not configured properly or if there is no DNS entry for the controller hostname, the AP may not be able to locate the controller. NTP, BOOTP, and AP hosts file are not relevant for this scenario.

NEW QUESTION # 106
You are performing a post-implementation validation survey. What basic tool can be used to easily locate areas of high co-channel interference?
  • A. Access point spectrum analyzer
  • B. Wi-Fi scanner
  • C. Throughput tester
  • D. Laptop-based spectrum analyzer
Answer: B
Explanation:
A Wi-Fi scanner is a basic tool that can be used to easily locate areas of high co-channel interference. A Wi- Fi scanner is a software application that can run on a laptop, tablet, smartphone, or other device that has a Wi- Fi adapter. A Wi-Fi scanner can scan the wireless environment and display information about the detected access points and client stations, such as their SSID, BSSID, channel, signal strength, security, and data rate.
A Wi-Fi scanner can also show the channel utilization and overlap of different access points, which can indicate the level of co-channel interference. Co-channel interference is a type of interference that occurs when multiple access points use the same or adjacent channels within the same coverage area. Co-channel interference can reduce the throughput and performance of the WLAN, as the access points and client stations have to contend for the channel access and avoid collisions. To identify areas of high co-channel interference, a Wi-Fi scanner can be used to measure the signal strength and channel utilization of different access points and compare them with a threshold or a baseline. Alternatively, a Wi-Fi scanner can also use a color-coded heat map to visualize the co-channel interference level in different locations. References: 1, Chapter 7, page
