A.

Site survey utility

B.

Wireless Network Management System

C.

Protocol analyzer

D.

Spectrum analyzer

E.

WLAN discovery tool

F.

Wireless Intrusion Protection System

What feature(s) are most likely to be supported by 802.11 enterprise-class WLAN controllers? (Choose 4)

A.

Link aggregation / port trunking

B.

802.1p and DSCP QoS

What statements about the beamwidth of an RF antenna are true? (Choose 2)

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.

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 802.11ac, changing the security mechanism from WPA2-Personal to WPA2-Enterprise will enable the VHT 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
