Question 96

The FAT AP can use the black and white list function to implement user access control. If a client MAC address is on both the black list and the white list, then:

A.This client can successfully access because only the MAC address on the whitelist is a valid MAC

B.This client cannot be successfully connected, because when the actual user accesses, its MAC address will be filtered by the blacklist first.

C.This client cannot be successfully connected, because when the actual user accesses, its MAC address will be filtered by the whitelist first, and then filtered by the blacklist.

D.This client can successfully access because only the MAC addresses on the blacklist are valid MAC addresses

Question 97

The description about hidden nodes is correct

A.cts-to-self is to solve the hidden node problem

B.In order to reduce the impact of hidden nodes in the indoor environment, the RTS/CTS function can be enabled on the AP side

C.The formation of hidden nodes between APs may result in collision and loss of packets sent by APs to STAs

D.In the outdoor AP+CPE environment, to reduce the impact of hidden nodes, the RTS/CTS function can be enabled on the AP side

Question 98

The 802.11 series of standards are only limited to the description of the MAC layer and the PHY layer.

A.error

B.correct

Question 99

The theoretical maximum transmission rate of WLAN usually refers to the transmission rate of large-byte (1500 bytes) packets, but in most networks, there are many small-byte (below 250 bytes) packets, which will seriously affect the practical application of WLAN. performance, making it well below the theoretical maximum rate. The above statement is true.

A.correct

B.error

Question 100

Enable the wireless user speed limit function on the SSID "H3C" of the Fat AP, the configuration is as shown in the figure.

Based on the above configuration, which of the following statements are correct?

A.If the number of users currently connected to this Fat AP is 10, the maximum bandwidth per user cannot exceed 20000Kbps.

B.The wireless user speed limit function of Fat AP is divided into static speed limit and dynamic speed limit. The above configuration realizes dynamic speed limit.

C.If the number of users currently connected to this Fat AP is 10, the bandwidth per user cannot exceed 20000/10=2000Kbps.

D.If the number of users currently connected to this Fat AP is 10, and 5 of them have no traffic, the bandwidth per user cannot exceed 20000/5=4000Kbps.
