D.

26dBm

Under the following conditions, if you want to deploy WLAN without interrupting service, please choose () controller as the best strategy:

Enterprise wireless terminals are 500, with notebooks, smart phones, wireless cameras, etc.; enterprise switching network access layer is 3700 series switching

The core layer is the 5700 series switch. The company's export is the NE20 router. Enterprises need to implement user grouping and QOS policies.

A.

Use the AR3260 to hang as AC

B.

Use AC6605 to connect directly to AC

C.

Use AC6605 to hang as AC

D.

Use the ACU2+77 switch to do AC

In general, which of the following obstacles has the greatest attenuation for the 2.4 GHz signal when the material is of the same thickness?

A.

Metal

B.

Asbestos

C.

Wooden door

D.

Colored glass

A WLAN engineer uses the WLAN Tester 2.0 tool for surveying. In order to quickly understand the coverage of the live signal, the following operations are correct.

A.

When viewing the survey, directly view the Wi-Fi signal scan box.

B.

Reduce the current drawing scale

C.

Before the survey, first add the AP group to speed up the simulation.

D.

Modify the global configuration parameters to simulate the data processing granularity to the maximum value, speed up the simulation speed

The throughput test of the wireless terminal in the WLAN wireless city scenario, the following description is correct under the same conditions?

A.

TCP flow is larger than UDP flow

B.

TCP flow is equal to UDP flow

C.

TCP flow is smaller than UDP flow

D.

Other options are wrong.

In the WLAN Tester 2.0 heat map, the tip box displays the following information. According to the information in the figure, the following statement is correct?

A.

Tip shows the signal information around the point

B.

Tip box must be placed on the heat map for 3S and above to display

C.

The SINR and PHY Data Rate that are not displayed in the Tip box are 0.

D.

Tip box only shows the SINR and PHY Data Rate of the maximum field strength value.

What is the operating temperature range of the Huawei outdoor AP8130DN?

A.

-20 degrees Celsius ~ +55 degrees Celsius

B.

-40 degrees Celsius ~ +60 degrees Celsius

C.

0 degrees Celsius ~ +60 degrees Celsius

D.

-40 degrees Celsius ~ +40 degrees Celsius

What is the default priority of VRRP?

A.

1

B.

0

C.

100

D.

255

The following options are incorrect about the WLAN forwarding mode description?

A.

The WLAN forwarding model includes two modes: local forwarding mode and centralized forwarding mode.

B.

The data forwarding mode of the datagram is also called the tunnel forwarding mode. The service data packets are uniformly encapsulated by the AP and then forwarded to the AC.

Line-to-AP management, also acting as a forwarding hub for AP traffic

C.

The datagram is forwarded in text, that is, the AP management flow is encapsulated in the CAPWAP tunnel and reaches the AC termination; the AP service flow is not encapsulated by the CAPWAP.

Directly sent by the AP to the switching device for direct forwarding

D.

The data packet is forwarded in a centralized manner, that is, the AP management flow is encapsulated in the CAPWAP tunnel and the AC is terminated. The AP service flow is not encapsulated by the CAPWAP.

Directly sent by the AP to the switching device for direct forwarding

What is the correct description of the WLAN site survey for different typical scenarios?

A.

The office surveys the main load-bearing columns and partitions to cover the impact. If it is an overall suspended ceiling, the AP should be considered as close to the maintenance port, if it is metal

Ceiling, you can choose to place the AP under the ceiling or wall mount

B.

If the wall of the school classroom is made of reinforced concrete, the signal attenuation is large. It is best to measure the attenuation when surveying. The teaching building should pay attention to the weak electricity room.

Set

C.

The ward inspection scene has high requirements for coverage field strength, roaming effect, and bandwidth requirements. At the same time, it is necessary to pay attention to the interference or disallow of medical equipment.

Area with Wi-Fi signal

D.

The stadium has a complicated environment and difficult wiring. Therefore, the weak house and the wiring should be confirmed with the property. If the distance is too far, it may be considered.

Adding an external switch, the survey should focus on mutual interference and installation methods between APs.
