Practice Test Question 3

Q.  During regular conference sessions, an 802.11g wireless network is overwhelmed with the amount of traffic it needs to process by wireless clients. Most of the additional traffic is from attendees’ mobile devices such as smart phones. What can be done to improve the performance of the wireless network?

A. Use a channel that doesn’t interfere with the smart phones
B. Use channel bonding
C. Switch to the 2.4 GHz frequency band
D. Add MIMO capabilities to the 802.11g network

N10-005: Exam Answer 1

Q.  Which of the following uses MIMO and OFDM?

A. 802.11a
B. 802.11b
C. 802.11g
D. 802.11n

D is correct. 802.11n uses multiple-input multiple-output (MIMO) technologies and orthogonal frequency-division multiplexing (OFDM). 802.11n is the only one of the listed wireless standards that uses MIMO.

A is incorrect. 802.11a uses OFDM but not MIMO.
B is incorrect. 802.11b uses direct-sequence spread spectrum (DSSS) instead of OFDM and it does not use  MIMO.
C is incorrect. 802.11g uses OFDM and DSSS, but not MIMO.

Objective:  3.3 Compare and contrast different wireless standards.

N10-005 Exam: Answer 2

Q.Which of the following wireless standards has the fastest transfer rate?

A. 802.11a
B. 802.11b
C. 802.11g
D. 802.11n

Answer D is correct. 802.11n has a maximum transfer rate of 600 Mbps, which is faster than the other standards.

A is incorrect. 802.11a has a maximum transfer rate of 54 Mbps.
B is incorrect. 802.11b has a maximum transfer rate of 11 Mbps.
C is incorrect. 802.11g has a maximum transfer rate of 54 Mbps.

Objective:  3.3 Compare and contrast different wireless standards.

N10-005: Answer 3

Q.  During regular conference sessions, an 802.11g wireless network is overwhelmed with the amount of traffic it needs to process by wireless clients. Most of the additional traffic is from attendees’ mobile devices such as smart phones. What can be done to improve the performance of the wireless network?

A. Use a channel that doesn’t interfere with the smart phones
B. Use channel bonding
C. Switch to the 2.4 GHz frequency band
D. Add MIMO capabilities to the 802.11g network

Answer B is correct. Channel bonding can be used to increase the maximum transfer rate from 54 Mbps to 108 Mbps on 802.11g.
A is incorrect. If cordless telephones were interfering with a wireless networks, changing the channel would reduce the interference. However, smart phones are the wireless clients using the wireless network, and they are not interfering with the wireless network.
C is incorrect. 802.11g uses the 2.4 GHz frequency band already.
D is incorrect. 802.11g does not support multiple-input multiple-output (MIMO) with multiple antennas. MIMO is used with 802.11n.
Objective:  3.3 Compare and contrast different wireless standards.
