Certified Wireless Network Administrator (CWNA): PW0-105

Given: The network administrator at XYZ Company recently attended a training class on wireless security and realized that he should 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 company security policy? (Choose 4)

A. Theft prevention and data security of WLAN infrastructure devices

B. Wireless intrusion monitoring and response procedures

C. WLAN performance analysis baseline documentation

D. Password requirements for users and infrastructure equipment

E. Training of the IT staff on WLAN operational security

F. User density planning and AP client association thresholds

What statement about 802.11 WLAN performance is true?

A. Use of larger frame sizes results in greater throughput in low interference environments.

B. BSS support for 65 KB A-MPDUs will increase the maximum data rate available to client devices.

C. In 802.11n, changing the security mechanism from WPA2-Personal to WPA2-Enterprise will enable the HT MCS rates.

D. Compared to an Independent BSS, an Infrastructure BSS can provide almost twice the throughput between wireless nodes.

E. Use of short guard intervals improves reliability and throughput in high multipath environments

What statements about the beamwidth of an RF antenna are true? (Choose two)

A. The lower the gain of an antenna, the more narrow one or both beamwidths become.

B. The beamwidth patterns on an antenna polar chart indicate the point at which the RF signal stops propagating.

C. Horizontal and vertical beamwidth are calculated at the points in which the main lobe decreases power by 3 dB.

D. Horizontal beamwidth is displayed (in degrees) on the antenna's Azimuth Chart.

E. Antenna beamwidth is measured in units of decibels relative to an isotropic radiator (dBi).
