H3CSE-WLAN Sample Questions:

1. The message used by STA to terminate the authentication relationship is

A) Association
B) Authentication
C) Deassociation
D) Deauthentication

2. When using a WLAN dual-band combiner for indoor distributed system combining and expansion, the following statements are correct:

A) The WLAN combination expansion scheme can increase the capacity of the entire WLAN system by using different channel combination of two APs.
B) During the project implementation, if using Fit AP for WLAN dual-band combination, it is recommended to enable the load sharing function of wireless controller + Fit AP, which can enable wireless users to connect to two APs evenly and avoid users on one AP. Many, while few users on another AP happen.
C) At present, due to the limitation of device characteristics, this expansion scheme only supports the expansion of channel 1 and channel 11. However, which of the two ports of the combiner is connected to the AP of channel 1 and which is connected to the AP of channel 11 is not strictly required. limit.
D) When using this combination expansion scheme, the insertion loss introduced by the WLAN combiner is about 2dB, which needs to be taken into account when calculating the signal strength.

3. The wireless client can search for the WLAN signal but cannot associate with the AP, the possible reasons are

A) There are strong sources of interference in the surrounding environment
B) Client wireless network card encryption method is inconsistent with AP
C) The AP distance is too far or there are too many obstacles, and the signal strength is lower than the receiving sensitivity of the wireless network card
D) Too many users associated with this AP

4. The smooth switching of FAT/FIT AP working mode mainly comes from ()

A) In the initial stage of network construction, APs work in FAT mode to meet the needs of small-scale networking
B) Purchase FIT/FAT dual-mode AP to protect the original investment
C) In the initial stage of network construction, make APs work in FIT mode, and add wireless controllers to meet the needs of large-scale networking
D) Change the working mode through commands to achieve smooth upgrade and simplify management operations

5. The use of wireless network has become more and more extensive. Compared with traditional wired network, the advantage of wireless network is shown.

A) Wireless network meets the mobility requirements of network applications in all walks of life, greatly improving work efficiency
B) It can provide higher data bandwidth and more stable network connection than wired network
C) Unrestricted by cables and ports, you can connect to the network in free space and use more freely
D) In certain geographical environments, it can greatly reduce the cost of network construction and make network construction more economical
