CWNP Wireless Network Administrator (CWNA) Sample Questions (Q131-Q136):

NEW QUESTION # 131
An 802.11 WLAN transmitter that emits a 50 mW signal is connected to a cable with 3 dB of loss. The cable is connected to an antenna with 16 dBi of gain. What is the power level at the Intentional Radiator?

Answer: D


NEW QUESTION # 132
What is the term for the additional amount of signal strength above the receiver sensitivity that provides a buffer against variable environmental conditions in an RF link?

Answer: C

Explanation:
Fade margin, also known as system operating margin (SOM), is the amount of extra signal strength built into an RF link beyond the minimum required receiver sensitivity. This buffer accounts for variables such as weather changes, seasonal foliage growth, temperature fluctuations, and minor obstructions that could otherwise cause a link to fail. A common design goal is a fade margin of at least 10-20 dB to ensure a reliable connection under changing environmental conditions.


NEW QUESTION # 133
What cause of hidden nodes within a BSS would be more likely lead to an increase in collisions and retries?

Answer: A


NEW QUESTION # 134
XYZ Company has decided to install an 802.11 WLAN system that will support 1083 wireless users, but they are concerned about network security. XYZ is interested in deploying standardized security features. In addition to WPA2-Enterprise with PEAP and role-based access control, XYZ would like to support management frame protection as well as a fast secure roaming protocol for future mobile handsets.
As XYZ Company selects a product to deploy, what two IEEE amendments, which are included in
802.11-2016, and 802.11-2020 should be supported to provide the management frame protection and fast secure roaming security features?

Answer: C

Explanation:
The two IEEE amendments that should be supported to provide the management frame protection and fast secure roaming security features are 802.11r and 802.11w12.
* 802.11r (Fast BSS Transition): This amendment to the IEEE 802.11 standard permits continuous connectivity aboard wireless devices in motion, with fast and secure client transitions from one Basic Service Set to another1.
* 802.11w (Management Frame Protection): This amendment increases the security of its management frames2.


NEW QUESTION # 135
What authentication method is referenced in the 802.11-2016 and 802.11-2020 specifications and is recommended for robust WI-AN client security?

Answer: C

Explanation:
The authentication method that is referenced in the 802.11-2016 and 802.11-2020 specifications and is recommended for robust WLAN client security is 802.1X/EAP. 802.1X/EAP stands for IEEE 802.1X Port-Based Network Access Control with Extensible Authentication Protocol and is a framework that provides strong authentication and dynamic encryption key generation for WLAN clients. 802.1X/EAP involves three parties: the supplicant (the client), the authenticator (the AP or the controller), and the authentication server (usually a RADIUS server). The supplicant sends its credentials (such as username and password, certificate, or token) to the authenticator, which forwards them to the authentication server. The authentication server verifies the credentials and sends a response to the authenticator, which grants or denies access to the supplicant. The authentication server also generates a master key that is used to derive encryption keys for the data frames between the supplicant and the authenticator. 802.1X/EAP supports various EAP methods that offer different levels of security and flexibility, such as EAP- TLS, EAP-PEAP, EAP-TTLS, EAP-FAST, and EAP-SIM. SSL, IPSec, and WEP are not authentication methods, but rather encryption or security protocols that are not specific to WLANs or referenced in the 802.11 specifications.
