H3C GB0-341-ENU 問題集

質問 1：
In the process of wireless network survey, which of the following statements is correct? (Multiple choice)
A. 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.
B. 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.
C. 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.
D. 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.
正解：A,B,C

質問 2：
In point-to-multipoint (PtMP) wireless transmission, the more suitable antenna type is?
A. All directional antennas
B. The central node uses an omnidirectional antenna, and the branch link uses a directional antenna
C. The central node uses a directional antenna, and the branch link uses an omnidirectional antenna
D. All omnidirectional antennas
正解：B

質問 3：
For coverage planning for areas with a large radius and few concurrent users, which of the following statement is correct? (Multiple choice)
A. Such areas can be covered by low-power APs respectively, and the coverage method can be based on the coverage of areas with small radius and few users. It is necessary to pay attention to the isolation of each AP frequency point during coverage.
B. deployed in such a multi-area AP, need to consider the AP divided between the channels, AP used between poor channel deployment with less interference, for example, when deploying three APs, the channels of AP1, AP2, and AP3 can be set to 1, 6 and 11 respectively
C. This type of area is the main WLAN indoor application place, such as comprehensive function area, hotel guest room, etc., this type of area can be divided into small areas according to rooms, walls, columns, etc., as a combination of multiple small radius and fewer users
D. This type of area can be covered by an indoor distributed system, using the sky of the original wireless network (such as PHS, CDMA, etc.) The feeder system combines WLAN systems to achieve the effect of one AP covering a larger area.
正解：A,B,C,D

A. WA220X-AGP
B. WA1208E-GP
C. WA2610-AGN
D. WA1208E-AGP
正解：A,B,D

質問 5：
Power management is an important attribute of wireless terminals. It will choose a balance between power consumption and adapter performance, which will affect the user's network experience. For example, usually the power management attribute of the Inter wireless network card is set to _______ to give full play to the maximum performance of the network card.
A. Default value
B. Lowest value
C. Highest value
D. Any value
正解：C

質問 6：
Which of the following are not the shortcomings of FAT AP?
A. FAT AP software is stored on the AP, and the software needs to be upgraded one by one when the software is upgraded, which requires a lot of maintenance work
B. The configuration of FAT AP is saved on the AP, the loss of AP equipment can cause the leakage of system configuration
C. No wireless controller required, can work independently
D. Each FAT AP only supports individual configuration, and the configuration of a large network requires a huge workload for AP configuration.
正解：C
