You are designing a wireless point-to-point connection between two buildings that are 5 miles (8 km)
apart. Which statement is true regarding the design, considering that there is a lake between the
two buildings?

A.
You do not need to be concerned about multipath, reflection, scattering, or refraction because
this is an outdoor design.

B.
A pair of workgroup bridges will need to be used to bridge Ethernet traffic over the air between
buildings.

C.
You need to be concerned with the even and odd Fresnel zones because they can result in signal
cancellation or amplification.

D.
You need to simplify the design by putting a router on each building because wireless APs or
bridges cannot carry 802.1Q traffic across the wireless link.

E.
Your concern should be the lake between the two buildings rather than the distance, because the
water will absorb the signal.
