What service must be implemented on your customers' network to authenticate users against an LDAP database prior to access to the WLAN infrastructure being granted?
A. NTP
B. RADIUS
C. SFTP
D. TLS
An amplifier has a 1 dB compression point of 32 dBm and a gain of 20 dB. Which is the highest average input power shown here that would be safe to operate a 24 Mbps 802.11g signal so that spectral regrowth is not a problem?
Response:
A. 5 dBm
B. 0 dBm
C. 5 dBm
D. 10 dBm
Of the following antenna connector types, which one is the smallest?
A. RP-TNC
B. MC Connector
C. N Connector
D. Male N Connector
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
What are some common problems with short (12 or fewer characters) ASCII passphrases in WPA/WPA2-Personal networks?
Response: A. They are more susceptible to dictionary attacks than longer passphrases.
B. They lead to weak group keys in a BSS.
C. They only produce a 64-bit PMK instead of a 256-bit PMK.
D. Very few AP and client vendors support entry of an ASCII-based passphrase.
During a post-validation assessment, you have configured a client for 802.1X/EAP but it is not passing authentication. Which areas should you check in the WLAN configuration?
Response:
A. Whether the RADIUS server is online and configured for the matching port on the APs and WLAN controllers
B. Whether the RADIUS shared secret is properly configured on the supplicant and authentication server
C. Whether the authenticator is configured to support the EAP type(s) your client is configured for
D. Whether the client has a fully valid certificate
What statement is true of a WLAN design that supports Real-Time Location Services (RTLS) with 802.11 RFID asset tags?
A. When passive tags are implemented, the AP density should be increased by 25% to make up for the shorter transmit range of passive tags as compared to active tags.
B. Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized with the AP for proper location of the tagged asset.
C. With passive tags, AP transmit gain should be increased to supply extra power for near- field coupling or backscatter modulation from the tag to the AP since the passive tag lacks an internal power source.
D. Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the tag reader to communicate tag information to the
While configuring your site survey software for an upcoming manual survey project, you notice the configuration option for "Network Card Simulation". What is the purpose of such a feature and when would you use it?
A. This setting allows the site survey software to convert the APs measured downlink RF data into a simulated data set as if the same data were transmitted by a specific client station. It is useful for determining uplink client performance when clients are located far from APs as well as projecting cell size for ad hoc networks.
B. Since WLAN adapters are not typically calibrated by manufacturers, this setting is a form of software calibration in which you can calibrate an (uncalibrated) adapter to match one of the calibrated adapters shown in the list. This process improves the reliability of RF data collection and reporting when uncalibrated adapters are used.
C. This is the configuration area in which you specify the adapter type that will be used for the site survey so that the survey software can interpret that adapters reported metrics (based on proprietary formulas) into an RF measurement that is standardized by the survey software and known to its users. This is done
Given: In a site survey deliverable report, you are expected to explain the spectrum measurements taken at the customers site. What portion of a spectrum analyzer view can be used to determine if a given channel is too active for use as the active channel for a new AP?
A. Device list
B. Frame decode
C. Real time FFT
D. Duty cycle
What is a radome?
A. A type of semi-circular ceiling found in atriums and that is a heavy cause of RF reflection.
B. A weatherproof piece of plastic covering an antenna or antenna system.
C. The unit used to measure the signal reflected backward by the end of a cable.
D. A piece of metal positioned behind APs mounted on outdoor poles, designed to limit the butterfly effect.
