Questions # 31:

Which of the following options are part of the lifecycle phase of a WLAN project operation?

Options:

Planning

Deployment

Upgrade

Operation and maintenance

Troubleshooting

Answer

A, B, D

Questions # 32:

What is wrong about the dual link backup description below?

Options:

The process of establishing the primary CAPWAP tunnel after the dual-link backup function is configured is the same as that of the normal CAPWAP tunnel.

If the dual-link active/standby configuration is configured with the dual-link active/standby configuration, the AP will preferentially select the dual-link active/standby configuration.

Dual-link cold standby is compared to hot standby. After detecting the failure of the primary CAPWAP tunnel, the backup CAPWAP tunnel is established to implement services. Break forwarding

Dual-link hot backup is relative to cold standby. The CAPWAP tunnel fault detection is performed between the active and standby ACs, and the HSB channel synchronizes the status information in real time.

Answer

A, C, D

Questions # 33:

Directional antennas have a stronger gain in signal strength in horizontal and vertical lobes, and no signal outside the lobes. So it is recommended to use high gain

Directional antennas to increase outdoor AP coverage distance.

Options:

True

False

Answer

Questions # 34:

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

Options:

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.

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

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

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

Answer

Questions # 35:

Which of the following factors affect the simu-lation rate value in the WLAN Tester 2.0 tool?

Options:

Field strength, signal to noise ratio, signal to noise ratio

Field strength, signal to noise ratio, bandwidth

Signal to noise ratio, bandwidth, field strength

Signal to interference and noise ratio, channel, bandwidth

Answer

Questions # 36:

In the 5W of the refined policy control in the Huawei WLAN network solution, What is the control method?

Options:

User role based access control

Time-based access control

Location-based access control

Policy control based on terminal type

Answer

Questions # 37:

WLAN engineers need to test the actual attenuation values of different channels in an obstacle in the room. Which of the following steps is correct?

1. Configure the 2.4G and 5G signals of the fat AP, place and turn on the signal source.

2. Select the obstacle to be tested

3. Using the signal scanning tool, test the field strength of the signal on both sides of the obstacle.

4. The subtraction of the two can calculate the attenuation value of the obstacle.

Options:

1234

2143

1324

2134

Answer

Questions # 38:

Which of the following two tools are needed to measure the attenuation value of an obstacle?

Options:

Surveying tools ------ tape measure, range finder

Observation record ------ telescope, camera

Signal source ------- fat AP

Signal scanning ------ laptop

Answer

C, D

Questions # 39:

For an open office area, there are 8 office areas, each with 10 people, each user requires a downstream bandwidth of 2Mbps, all users

The Internet concurrency rate is 80%. How many AP5030DN are needed for this office building? The measured rate of each AP is about 80Mbps, regardless of the fading

Other factors such as subtraction, interference, etc., only calculate the number of APs from the bandwidth.
