A.    The frequency range of these bands is 5000 MHz – 5200 MHz
B.    Each of these two bands contain five 20 MHz channels.
C.    Regulatory domains worldwide require DFS and TPC in these bands.
D.    These bands have a total combined bandwidth of 200 MHz.
E.    20 MHz in each of these bands is reserved as a guard band.

Answer: DE

Given: Two co-located 802.11b/g/n APs can interfere with one another and cause contention and collisions, even when the two APs are operating on non-overlapping channels (e.g. 1 & 6).
What deployment flaw could cause this problem? (Choose two)

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 using active scanning to probe for access points on multiple channels.
D.    The output power on the access points is too high.
E.    A client station authenticates to both access points, but does not associate.
F.    The access points are not synchronized to the same NTP server.

Answer: AD

Given: XYZ Corporation is experiencing connectivity problems with their existing building-to- building bridge link. A concrete wall on the roof of one building is partially blocking the Fresnel Zone, and the connection is dropping many frames. The administrator moves the antenna to an area not obstructed by the concrete wall and then realizes the RF cable cannot reach the new location.
If an extension cable is added to move the antenna, what are the likely results?

A.    The data throughput rate will increase because VSWR will decrease.
B.    The Equivalent Isotropically Radiated Power (EIRP) will decrease.
C.    The antenna’s azimuth beamwidth will decrease.
D.    The size of the Fresnel zone will increase.
E.    The likelihood of a direct lightning strike will increase.

Answer: B

What specifications should be evaluated for an antenna before it is implemented in a WLAN system? (Choose three)
