Questions # 52:

What is the correct description of the indoor distributed AP?

Options:

A.

The AP6310SN has only one radio port.


B.

AP9330DN room division scheme, 20m feeder is not recommended


C.

The RF cable of AP9330DN and AP9430DN can be shared.

Questions # 53:

The AP number is calculated only from the bandwidth without considering other factors such as attenuation and interference. Take 802.11n as an example: the measured rate of each AP.

About 100Mbps, there are 10 office areas in an office building, 40 people per office area, and customers require bandwidth per terminal.

2Mbps, all users online companion rate is calculated according to 70%, how many APs are needed for the office building?

Options:

A.

4


B.

5


C.

6


D.

7

Options:

A.

True


B.

False

Questions # 56:

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?

Options:

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.

Questions # 57:

The following description of the BYOD networking of large enterprises is wrong?

Options:

A.

The network is divided into access layer, distribution layer and core layer.


B.

AP is connected to the access layer switch. It is recommended to use a PoE switch.


C.

AC can be implemented using the built-in AC card of the core switch.


D.

At the access layer, you can use the side-mounted CA to implement wireless centralized control.

Questions # 58:

What is wrong with the WoC scheme in the following options?

Options:

A.

The WLAN and CATV signals are mixed by the signal combiner and input to the existing CATV cable, and transmitted to the CATV coaxial shielded cable.

In the room, finally separate the signals through the splitter panel to achieve indoor wireless network coverage and TV signal transmission.


B.

The overall construction of WoC does not need to be changed too much, the construction impact is negligible, and the wireless coverage is better. It is excellent in wireless system transformation projects.

Obvious


C.

Signal combiner and WoC panel, need to be customized separately from the partner


D.

At present, the cable commonly used by CATV is SY(W) V75-5 coaxial cable, which is specially produced for cable TV. The transmission frequency of 2.4G is very small, so the distance from AP to terminal panel can be longer, but it is recommended not to exceed 500 meters


Expert Solution
Questions # 59:

The maximum transmission power of indoor WLAN products stipulated by international standards is 100mw, which is equivalent to?

Options:

A.

1dBm


B.

10dBm


C.

20dBm


D.

30dBm


Expert Solution
Questions # 60:

When using the WLAN Tester 2.0 tool, the dot speed is preferably controlled from 0.8m/s to 1.2m/s. What is the correct statement about the dot speed?

Options:

A.

The speed is too fast, the heat map is not accurate, and the heat map abnormality may occur.


B.

The speed is too slow, the amount of sampled data is too large, and the heat map calculation time is lengthened.


C.

Signal collection is a process that takes enough time to save


D.

This is to ensure that the normal walking speed of ordinary people is consistent.
