5. A. The received signal strength represents how much of a transmitted signal is being received.

If this signal is weak, the difference between the signal and noise may not be high enough

to recover the data. If the power on an access point is high, it would provide more received

signal. A signal-to-noise ratio of 35 dB is more than adequate. If the radio on the client was

disabled, it would not be able to connect at all. For more information, see Chapter 11.
