A. Wrap it with insulating tape first, then wrap it with a layer of insulating tape, and finally add a layer of waterproof tape to seal it.

B. Wrap it with insulating tape first, then wrap it with a layer of waterproof tape, and finally add a layer of insulating tape to seal it.

C. Wrap it with waterproof tape first, then wrap it with a layer of insulating tape, and finally add a layer of insulating tape to seal it.

D. Wrap it with waterproof tape first, then wrap it with a layer of insulating tape, and finally seal it with a layer of waterproof tape.

A. Whether the distance between APs is appropriate and whether there are obstacles in the middle

B. If the antenna angles at both ends aligned or not

C. Two APs must work on the same channel

D. The local AP correctly configures the MAC address of the opposite AP, that is, peer-mac

A. True

B. False

A. 23dBm

A. It is recommended to use local power supply for high-power APs;

B. Prefer local power supply.

C. Must require constant voltage power supply

D. The protective ground (PE) of the AC power supply must be reliably grounded

A. The wireless switch is a Layer 3 device, only one VLAN interface IP address and system IP address (usually the same) can be configured, and only static routing can be configured.

B. H3C's universal wireless solution can be deployed on any existing Layer 2 or Layer 3 LAN topology without the need to reconfigure the backbone or hardware. Wireless switches and managed access points AP can be located anywhere in the network.

C. AP zero configuration, console port is useless, the hardware is mainly composed of CPU + memory + RF, configuration and software must be downloaded from the wireless switch.

A. 1 or 0

A. Triangular deployment

B. Even deployment

C. Deploy left and right separately

D. Keep away from corners and obstacles

A. -80dBm ； -75dBm

B. -90dBm ； -85dBm

C. -85dBm ； -80dBm

D. -75dBm ； -70dBm

A. 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.

B. 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.

C. 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.

D. 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.

A. AES

A. True

B. False

A. Beacon

B. RTS

C. CTS

D. ACK

A. Power supply

B. AP

C. Cable (network cable, feeder, power cord)

D. Antenna

A. For a distributed deployment design with the same environment layout on each floor, a uniform and symmetrical antenna feeder design can be selected. For example, the combined location of each floor, the number of APs, the number of couplers and power splitters, and the device specifications can all be unified

B. When adding AP joint points on the original indoor sub-system, if the original system has power amplifier equipment, the AP joint position should be selected behind the power amplifier device.

C. Under normal circumstances, there cannot be more than 1 WLAN signal on the main path of the combined system, which will cause mutual interference of WLAN signals and fail to demodulate.

D. There are two ways to expand the capacity of the combined system. One is to modify the antenna at the end of the system, insert a combiner, and add APs; the other is to use a dedicated WLAN dual AP combiner

A. The applied Active Key has a binding relationship with the relevant device, and this Active Key can only be used on this device (the relevant information of this device is provided at the time of application)

B. The license key of the H3C wireless controller is an authorized serial number, such as 173995EA490E3C14A9A66

C. There is no binding relationship between the applied Active Key and related equipment. This Active Key can be used on any equipment of the same model.

D. When applying for the Active Key of the wireless controller, you need to provide the relevant information of the device (device serial number, verification code) and the license key.

A. 802.11a

B. 802.11b

C. 802.11ac

D. 802.11g

E. 802.11n

A. CSMA/CA, after waiting for the length of IFS time, start a timer Back-off Timer, and start sending messages when the timer counts down to zero.

B. CSMA/CA, after waiting for the length of IFS time, send data immediately, if conflict occurs, start a timer Back-off-timer, and resend the message when the timer counts down to zero.

C. CSMA/CD, after waiting for the length of IFS, send data immediately, if conflict occurs, start a timer Back-off-timer, and resend the message again when the timer counts down to zero.

D. CSMA/CD, after waiting for the length of IFS time, start a timer Back-off Timer, and start sending messages when the timer counts down to zero.

A. Be aware of obstacles in the Fresnel area, such as cutting down trees.

B. Choose a good relay device.

C. Choosing a high-performance antenna can solve the "partially invisible" problem.

D. Raise the height of the antenna
