1. In the survey of outdoor bridge, the main consideration is the problem of wireless line of sight. The opposite end's antenna should be visible on the site, and there should be no obstacles in the middle. In general, solving the line-of-sight problem and the I Fresnel interval problem can be done by the following methods.
Which is the most simple and effective way?
A) Choose a high-performance antenna, which can solve the "partially invisible" problem.
B) Clear obstacles in the Fresnel area, such as cutting down trees.
C) Choose a good repeater.
D) Raise the height of the antenna
2. The media access mechanism of an 802.11 network is ______. In this mechanism, when the sender detects that the media is idle _______.
A) CSMA/CA: After waiting for the IFS time length, start a timer Back-off Timer, and start sending messages when the timer counts down to zero.
B) CSMA/CD: After waiting for the IFS time length, send data immediately, if a conflict occurs, start a timer Back-off-timer, when the timer counts down
C) CSMA/CD: After waiting for the IFS time length, start a timer Back-off Timer, and start sending messages when the timer counts down to zero.
D) CSMA/CA: After waiting for the IFS time length, the data will be sent immediately. If there is a conflict, a timer Back-off timer will be started, and the message will be resent when the timer counts down to zero.
3. Note when using AP for wireless bridging
A) The local AP correctly configures the MAC address of the peer AP, that is, peer-mac
B) Whether the distance between APs is appropriate and whether there are obstacles in the middle
C) Whether the antenna angles at both ends are aligned
D) Both APs must work on the same channel
4. The survey and design of the wireless network is a key link in the implementation of the WLAN project. A good survey and design scheme can
A) Reduce the maintenance workload of the wireless network
B) Completely solve the problem of interference sources in wireless networks
C) Ensure the stable operation of the wireless network
D) Improve the efficiency of equipment usage, thereby increasing customer ROI
5. What are the commonly used troubleshooting commands for WLAN network failures?
A) debugging command
B) display command
C) tracert command
D) ping command
