QUESTION 81
The following statement is correct

When covering multiple floors, the channel setting should consider the signal interference in the three-dimensional space.

The user isolation function can reduce the impact of broadcast packets and user traffic on the network, and also avoid some ARP attacks, making the wireless network stable and safe to use.

WLAN dual-band combiner is used for capacity expansion, which is fast in implementation and low in cost. It can quickly double the number of access users in hotspot areas, and can easily deploy functions such as load balancing.

WLAN and PHS have similar frequency bands and air attenuation. When the power of the equipment is the same, the coverage is similar, which provides favorable conditions for the co-site construction of WLAN and PHS.

QUESTION 87
Which of the following statements about AP equipment grounding specifications is correct?

The indoor AP should be grounded. The outdoor AP, antenna and lightning protection device, and PoE module must be grounded. The grounding resistance should be less than 5 ohms. The grounding wire should not exceed 30 meters.

When the multi-strand ground wire (generally not single-core) is connected to the ground bar, a ground terminal (copper nose) must be installed. The size of the ground terminal should be consistent with the wire diameter, and the pressure (welding) connection should be firm.

The contact part between the ground terminal and the ground bar should be flat and tight, without rust and oxidation, and should be coated with Vaseline or butter to prevent rust when connecting different materials.

The principle of fixing the ground wire of the PVC pipe is the same as that of the RF wire. When installing wire grooves, the fixed spacing of wire grooves is 0.3 meters. The radius of curvature of the ground wire should be greater than 130mm.

QUESTION 88
Which description is correct about WIPS for wireless intrusion detection?

Antenna EIPS (WIPS) can detect potential safety hazards in time and provide early warning of safety strategies by scanning communication and collecting airborne information.

The AP with WIPS function enabled can not only provide wireless service, but also perform detection and scanning

WIPS function can attack illegal AP or station

The WIPS function can detect the flood attack of 802.11 antenna packets, and can automatically add to the blacklist after detection

QUESTION 89
The H3C wireless controller can use the command “display wlan ap all verbose” to view the detailed information of AP registration. The following output is the detailed information of an AP viewed through this command.

From the above information, it can be known that _

The model of this AP is WA2100-AG, the status is RUN (registered successfully), and the IP address is 192.168.0.125

This AP has been registered and online for 42 minutes and 50 seconds. It can be judged whether this AP has been disconnected according to the running time of the wireless controller.

Last Join Address Indicates the IP address used by the AP when it successfully established a link with the AC last time. When the AP is disconnected, you can try to telnet to the AP through this address

Admin State is DOWN, indicating that the AP’s radio may be in the disabled state

There are currently no users on this AP because the Running Clients Count is 0

QUESTION 90
The correct procedure to configure the radio 1 channel of AP1 to 6 in the H3C wireless controller is

[H3C] wlan ap ap1 [H3C-wlan-ap-ap1] radio 1 [H3C-wlan-ap-ap1-radio-1] channel 6

[H3C] wlan ap ap1 [H3C-wlan-ap-ap1] radio 1 channel 6

[H3C] wlan ap ap1 radio 1 channel 6

[H3C] wlan ap ap1 radio 1 [H3C-wlan-ap-ap1-radio-1] channel 6

QUESTION 91
