CWNA-107 Certified Wireless Network Administrator (CWNA) practice exam questions

1. A dual-band 802.11ac AP must be powered by PoE. As a class 4 device, what power level should be received at the AP?

2. A WLAN is implemented using wireless controllers. The APs must locate the controllers when powered on and connected to the network.

Which one of the following methods is commonly used to locate the controllers by the APs?

3. You are implementing a multi-AP WLAN and fast secure roaming is essential.

Which one of the following methods is an IEEE 802.11 standard method for fast roaming?

4. In an 802.11 2.4 GHz system, what 22 MHz channels are considered non-overlapping?

5. The center frequency of channel 1 in the 2.4 GHz band is 2.412 GHz (2412 MHz).

What is the center frequency of channel 4?

6. The requirements for a WLAN you are installing state that it must support unidirectional delays of less than 150 ms and the signal strength at all receivers can be no lower than -67 dBm.

What application is likely used that demands these requirements?

7. You are deploying a WLAN with the access points configured for 10 mW of output power on the 2.4 GHz radios and 20mW of output power on the 5GHz radios. Some semi-directional antennas are also in use.

What kind of deployment is described?

8. Option 43 must be configured to allow access points to locate controllers. In what network service should this option be configured?

9. What statement about 802.3, Clause 33 Power over Ethernet is true?

10. What statement describes the authorization component of a AAA implementation?

11. You are the network administrator for ABC Company. Your manager has recently attended a wireless security seminar. The seminar speaker taught that a wireless network could be hidden from potential intruders if you disable the broadcasting of the SSID in Beacons and configured the access points not to respond to Probe Request frames that have a null SSID field.

Your manager suggests implementing these security practices.

What response should you give to this suggestion?

12. What cipher suite is specified by the 802.11-2016 standard and is not deprecated?

13. To ease user complexity, your company has implemented a single SSID for all employees.

However, the network administrator needs a way to control the network resources that can be accessed by each employee based in their department.

14. ABC Company is planning a point-to-multipoint bridge deployment with standalone (autonomous) 802.11 bridge units. 802.1X/EAP will be used for bridge authentication. A Linux-based RADIUS server will be used for authentication.

What device in the bridge implementation acts as the 802.11X Authenticator?

15. You are managing a wireless access point in autonomous mode using the Web based interface. You capture traffic during this management task and notice that you can see the HTML code of the Web pages for access point management.

What error in administration could be the cause of the security concern?

16. What is the most effective method of testing roaming in relation to 802.11 VoIP handsets?

17. You are performing a post-implementation validation survey.

What basic tool can be used to easily locate areas of high co-channel interference?

18. During a post-implementation survey, you have detected a non-802.11 wireless device transmitting in the area used by handheld 802.11g scanners.

What is the most important factor in determining the impact of this non-802.11 device?

19. A non-802.11 device is suspected of causing interference on the WLAN. You are not certain of the location or type of device.

What is the best solution for locating this non-802.11 device?

20. You are tasked with performing a throughput test on the WLAN. The manager asks that you use open source tools to reduce costs.

What open source tool is designed to perform a throughput test?
