問題7

WLAN "Theoretical Maximum Transmission Rate" usually refers to the transmission rate of large-byte (0 1500 bytes) packets, but in most networks, there are more small-byte (below 250 bytes) packets. Will seriously affect the actual application performance of WLAN, making it far below the theoretical maximum rate.

A. False

B. True

正確答案: B

問題8

In the 802.11i standard, which protocol that needs to be encrypted by hardware? so the hardware support of the network card is required.

A. AES

正確答案: A

問題9

In the process of wireless network survey, which of the following statements is correct? (Multiple choice)

A. When deploying indoor multiple APs, in order to ensure a good signal strength index, the AP should work at the maximum transmit power, and attention should be paid to the channel division between APs.

B. When deploying indoor multiple APs, in order to meet the wireless application requirements of a certain user density, the appropriate AP installation location, installation method, transmission power, etc. Reduce the number of visible signals in the three-dimensional space as much as possible.

C. When planning signal coverage in a three-dimensional space, the problem of signal leakage across floors is unavoidable. Therefore, the degradation of wireless link quality caused by signal leakage needs to be considered and optimized.

D. When conducting wireless network surveys, it is necessary to ensure that the coverage area is the same as the actual application area. When the signal coverage is affected by obstacles and the wireless signal coverage cannot meet the actual application requirements, the deployment plan needs to be adjusted in time.

正確答案: B,C,D
