In the WLAN Tester 2.0 tool, when a vendor group information is added to an AP packet in the global configuration, can one vendor correspond to several OUIs?

A. 1

B. 2

C. 3

D. Multiple

Basic requirements for WLAN network construction include bandwidth requirements, coverage targets, coverage methods, field strength requirements, and power distribution methods. Determining the strength of the coverage area in the field strength requirement is adjusted by the AP transmit power. The following statements are correct regarding the requirements that the network regulation needs to consider in advance.Is it?

A. The field strength demand in key areas is that the main online area of the user can be controlled at -40~-80dBm. If the power is too strong, it will easily lead to receiving overload, and the power is too weak.Will cause the connection rate to drop

B. The interference field strength requirement is that the same-frequency interference in the same area is not more than -80dBm

C. The fringe field strength level combined with the receiving sensitivity and edge bandwidth requirements are generally selected above -75dBm

D. The leakage field strength of the system should not be too large, and the field strength at 10m of the external network of the building cannot be greater than -90dBm.

Usually, what is the attenuation of 2.4GHz at 10 meters?

A. 32dB

B. 53dBm

C. 71dBm

D. 92dB

After the deployment of the WLAN project is completed, which of the following tools is required for acceptance?

A. WLAN Survey

B. WLAN Tester 2.0

C. WLAN Planner

D. Antenna Alignment

As shown in the figure below, a city will install cameras (2 per school) in the entrances of multiple schools (yellow points in the picture). The camera does not support wireless functions, and there is only one network port. There is no switch on site, customers want to pass The WLAN passes the data back to the location of Main C4 in the figure (red standard Note), the two points connecting the red line in the figure are 3km apart. According to the calculation of 2Mbps bandwidth for each camera, there is a line of sight between the school gate and Main C4. Which of the following solutions can meet the above scenarios begging?

A. Each school deploys 1 AT815SN and 1 AP6510DN (with external antenna)

B. One AT815SN and one AP8030DN per school

C. 2 AP8130DN (with external antenna) deployed in each school

D. 2 AP6610DN (with external antenna) deployed in each school

E. Two AP6510 (with external antenna) deployed in each school

Assume that the Root AP is installed on a 30-meter tower with coordinates (0m, 0m), and four Leaf APs are at (200m, 100m). (200m, 0m), (800m, 400m) and (1000m, 0m) in the four positions of the 7-meter pole, all equipment used AP6510DN, and the antenna is the same. Each Leaf AP requires 1 Mbps of bandwidth and the local EIRP is unlimited. Which of the following antennas is optimal for a Root AP?

A. 11dBi_H60 degrees _V30 degrees

B. 27dBi_H5 degrees _V5 degrees

C. 18dBi_H15 degrees _V15 degrees

D. 13dBi_H15 degrees _V60 degrees

Which of the following three formats can be planned with the WLAN planning tool?

A. Google Earth

B. Bitmap (jpg, gif, bmp, etc.)

C. PDF drawings

D. Vector graphics ( ai, odr, etc.)

The device selected for a WLAN project is AC6605. Which of the following networking scenarios is applicable to this independent AC solution?

A. WLAN overlay networking

B. Independent management of wired and wireless services

C. Wired and wireless traffic convergence and forwarding

D. Unified management of wired and wireless users

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

Which of the following addresses can be used as an internet address?

A. 10.1.1.6/30

B. 10.1.1.7/30

C. 172.18.1.17/30

D. 224.1.1.16/30
