Question 19

What statement about 802.11 WLAN bridges is true?

A. WLAN bridges only work in the 2.4 GHz frequency band and they support only SISO communications

B. WLAN bridges must use a channel with acceptable SNR at both transceivers to maintain the desired data rate bi-directionally

C. WLAN bridges may support MIMO communications, but only if used in the 5 GHz frequency band

D. WLAN bridges must be implemented such that no interference occurs on the channel anywhere between the two endpoints used to establish the bridge

Correct Answer:C

Question 20

When using an RF splitter to connect one transceiver to sector antennas loss is incurred. What is this loss called?

A. Conversion loss

B. Intentional loss

C. Through loss

D. Active loss

Correct Answer:C

Question 21

You support a WLAN using dual-band 802.11ac three stream access points. All access points have both the 2.4 GHz and 5 GHz radios enabled and use 40 MHz channels in 5 GHz and 20 MHz channels in 2.4 GHz. A manager is concerned about the fact that each access point is connected using a 1 Gbps Ethernet link. He is concerned that the Ethernet link will not be able to handle the load from the wireless radios. What do you tell him? 2.4

A. His concern is valid and the company should upgrade all Ethernet links to 10 Gbps immediately.

B. His concern is valid and the company should immediately plan to run a second 1 Gbps Ethernet link to each AP.

C. His concern is invalid because the AP will compress all data before transmitting it onto the Ethernet link.

D. Due to 802.11 network operations and the dynamic rates used by devices on the network, the two radios will likely not exceed the 1 Gpbs Ethernet link.

Correct Answer:A

Question 22

A natural disaster has occurred in a remote area that is approximately 40 miles from the response team headquarters. The response team must setup a local wireless network using 802.11 WLAN access points. What is the best method, of those listed, for implementation of a network backhaul for communications across the Internet in this scenario?

A. Temporary wired cable

B. 802.11 bridging

C. Cellular/LTE

D. Temporary wired DSL

Correct Answer:C

Question 23

What is an advantage of using WPA2-Personal instead of WEP-128 as a security solution for 802.11 networks?

A. WPA2-Personal uses CCMP for encryption, and WEP-128 uses TKIP for encryption

B. WPA2-Personal uses dynamic encryption keys, and WEP-128 uses static keys

C. WPA2-Personal uses 802.1X/EAP for authentication, and WEP-128 uses preshared keys

D. WPA2-Personal is based on IEEE 802.11 industry standards, but WEP is not

Correct Answer:B

Question 24

You are tasked with performing a throughput test on the WLAN. The manager asks that you use open source tools to reduce costs. What open source tool is designed to perform a throughput test?

A. IxChariot

B. Python

C. PuTTy

D. iPerf

Correct Answer:D
