CWNA-106 Online Practice Questions and Answers

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 on their department. What WLAN feature would allow the network administrator to accomplish this task?

A. SNMP

B. VRRP

C. RBAC

D. IPSec

E. WIPS

F. WPA2

The network administrator at XYZ Company recently attended a training class on wireless security and realized that heshould update the corporate security policy to address WLAN technology. The network administrator is listing the items that should be addressed in the security policy update, and has asked for your input.

What WLAN topics should be addressed by a companysecurity policy? (Choose 3)

A. Theft prevention and data security of WLAN infrastructure devices

B. Wireless intrusion monitoring and response procedures

C. WLAN performance analysis baseline documentation

D. Wired network performance analysis andbaseline documentation

E. Training of the IT staff on WLAN operational security

F. User density planning and AP client association thresholds

The IEEE 802.11a/n/ac physical layer technologies utilize the 5 GHz frequency band. What is true ofthe channels in this frequency spectrum?

A. 14 channels are available worldwide.

B. 11 channels are available worldwide.

C. Regulatory domains worldwide require DFS and TPC in all these channels.

D. DFS may be required in some regulatory domains on somechannels.

E. 802.11 channels areseparated by 5 Mhz

XYZ Company has hired you to perform an indoor site survey of their 5-storyfacility. They own the building and rents out unused floors (floors 2 and 4) to other companies, and the other companies already use

802.11 WLANs. XYZ Company wants all of the offices they occupy to be surveyed as part of the project.

What actions should be recommended as part of the site survey project? (Choose 2)

A. Verify that RF signals from XYZ Company's APs are not penetrating outside the perimeter of the building.

B. Determine how much signal strength is passing between floors.

C. Locate wiring closets on each floor occupied by XYZ Company.

D. Identify security best practice violations on neighboring WLANs.

E. Verify that XYZ Company's APs are not directly above or below APs on adjacent floors.

In a long-distance RF link, whatstatement about Fade Margin is true?

A. Fade Margin is an additional pad of signal strength designed into theRF system to compensate for unpredictable signal fading.

B. The Fade Margin of a long-distance radio link should be equivalent to the receiver's antenna gain.

C. A Fade Margin is unnecessary on a long-distance RF link if more than 80% of the first Fresnelzone is clear of obstructions.

D. The Fade Margin is a measurement of signal loss through free space, and is a function of frequency and distance.

What are two channel modes specified by the 802.11n (High Throughput) PHY? (Choose 2)

A. 20 MHz

B. 20/40 MHz

C. 40/80 MHz

D. 22 MHz

E. 80 MHz

F. 160 MHz

In a single channel architecture (SCA) WLAN system, 802.11n (HT) APs should not share an SSID with 802.11g (ERP) APs.

What is the reason for this recommendation?

A. Client stations would see two different sets of AP capabilities as they roam between APs with the same BSSID.

B. The added range of 802.11n APs would cause additional co-channel interference.

C. The additional beacon material in 802.11n beacons wouldconfuse 802.11b/g client stations.

D. Beacons from 802.11n APs use 40 MHz channels, while beacons from 802.11g APs use 20 MHz channels.

Two co-located 802.11b/g/n APs caninterfere with one another and cause contention and collisions, even when the two APs are operating on non-overlapping channels (e.g. 1 and 6).

What deployment flaw could cause this problem? (Choose 2)

A. The access points are mounted too closely to one another.

B. Reflective objects in the area are causing significant multipath.

C. A client station is usingactive scanning to probe for access points on multiple channels.

D. The output power on the access points is too high.

E. A client station authenticatesto both access points, but does not associate.

F. The access points are not synchronized to the same NTP server.

You are being interviewed by ABC Company for employment as a wireless site surveyexpert. The interviewing manager asks you what items should be included in a site survey report generated as part of a manual site survey process.

What answer would be accurate?

A. Itemized list of equipment, licenses, and support contracts required forthe facility

B. RF heat map illustrating coverage and signal quality for each frequency band

C. Documentation proving proper entry of wall material types into the site survey software

D. Documentation noting how each WLAN user group will authenticate to the network

ABC Company has thousands of Wi-Fi users accessing their network on a daily basis. Their WLAN consists of 700 access points, 6 WLAN controllers, and a wireless network management system.

Whatnetwork functions are performed by the enterprise-class WNMS?

A. Radio management, fast roaming, key caching, and other centralized control plane operations

B. Centralized bridging of guest data traffic and application of firewall and QoS policies to data

C. Management of WLAN controller configuration and provisioning of firmware updates

D. Generating, encrypting, and decrypting 802.11 frames and collecting RF radio data.
