Question 76

You are evaluating a connection that states the data rate is 150 Mbps. What is the expected throughput of
this connection?

A.Less than 150 Mbps because of 802.11 overhead and contention

B.54 Mbps because that is the actual maximum throughput of an 802.11 connection

C.150 Mbps because the data rate is equal to the throughput

D.More than 150 Mbps because of compression

Question 77

What statement about 802.11 WLAN performance is true?

A.To get the best performance out of an AP, you should disable data rates of 72 Mbps and lower

B.In most WLANs, no special skill or tuning is required to get peak performance

C.WLANs perform better as more wireless clients connect with each AP

D.In modem networks, both centralized and distributed data forwarding work well for most standard office deployments

Question 78

ABC Company is planning to install a new 802.11ac WLAN, but wants to upgrade its wired infrastructure first to provide the best user experience possible. ABC Company has hired you to perform the RF site survey. During the interview with the network manager, you are told that the new Ethernet edge switches will support VoIP phones and 802.11 access points, both using
802.3 PoE.
After hearing this information, what immediate concerns do you note?

A.VoIP phones and 802.11 access points should not be powered by the same edge switch due to distortion.

B.The power budget in the edge switches must be carefully planned and monitored based on the number of supported PoE devices.

C.If the switches are in optimal locations for VoIP phones, they are likely to be suboptimal locations for 802.11 APs

D.The edge Ethernet switches should support Ether-channel to get the best results out of the network.

Question 79

Lynne runs a small hotel, and as a value added service for her customers she has implemented a Wi-Fi hot-spot. Lynne has read news articles about how hackers wait at hot- spots trying to take advantage of unsuspecting users. She wants to avoid this problem at her hotel.
What is an efficient and practical step that Lynne can take to decrease the likelihood of active attacks on her customers' wireless computers?

A.Implement an SSL VPN in the WLAN controller that initiates after HTTPS login.

B.Enable station-to-station traffic blocking by the access points in the hotel.

C.Require EAP-FAST authentication and provide customers with a username/password on their receipt.

D.Implement Network Access Control (NAC) and require antivirus and firewall software along with OS patches.

Question 80

What statement is true concerning the use of Orthogonal Frequency Division Multiplexing (OFDM) modulation method in IEEE 802.11 WLANs?

A.OFDM was used by Frequency Hopping Spread Spectrum (FHSS) PHY devices.

B.OFDM was first introduced in 802.11 and is used by the ERP, HT and VHT PHYs as well.

C.OFDM implement BPSK modulation to allow for data rates up to 7 Gbps.

D.OFDM modulation is used only in 5 GHz 802.11 transmissions.
