Question 80

What might limit the ability to locate 802.11 clients using a WLAN infrastructure without an 802.11 tag?(Choose all that apply.)

Options:

A.

Lack of 802.11k support

B.

When its radio is disabled

C.

When it is off

D.

RF channel selection

Question 81

Why does a frame transmitted at 1 Mbps have a greater usable range than the same frame transmitted at 54 Mbps?

Options:

A.

Free space path loss causes greater signal dispersion for higher rate transmissions.

B.

Receiver sensitivity requirements are lower for frames transmitted with less complex modulation and coding.

C.

To improve reliability, 802.11 STAs increase transmit power as the signaling rate decreases.

D.

Lower data rate RF transmissions travel at higher speeds and are less likely to experience collisions.

Question 82

A wireless engineer from your company performed a site survey in an office building where a wireless network extension was needed. He reports

that while performing a Layer 1 sweep near a meeting room full of people, he detected RF activity with a very low duty cycle. He is unsure how to

interpret what he recorded to determine its impact on a future Wi-Fi network.

What is true about this RF environment and its potential impact on the WLAN?

Options:

A.

The signal affects the entire spectrum and will render the wireless network unusable. It must be located and removed.

B.

The signal has a low duty cycle and should not be of major impact on the wireless network.

C.

The signal is alternating between peaks (high interference level) and valleys (low interference level). The network channel design must be

built to avoid the affected peak frequencies.

D.

The signal is typical of a high radio card background noise. It shows that the card used for the Layer 1 sweep should be replaced and the

Layer 1 sweep re-

Question 83

When using a predictive design tool, you have selected APs with an antenna gain 3 dBi and set the transmit power of the predicted APs to 25 mW. What should be EIRP of the APs in the design?

Response:

Options:

A.

17 dBm

B.

125 mW

C.

11 dBm

D.

6.25 mW
