A. True

B. False

A wireless AP and wireless terminal support MIMO 2*2. When the AP works in HT20 mode, which of the following data is closest to the wireless terminal? Throughput (the terminal is in the key coverage area)?

A. 30Mbps

B. 90Mbps

C. 150Mbps

D. 300Mbps

When the WLAN is covered outdoors, the following description is correct about the antenna hanging high?

A. In order to ensure coverage of a larger area, the antenna should be as high as possible

B. In order to ensure that there is no black under the tower, the antenna should be as low as possible.

C. Directional antenna hanging height is not recommended more than 12m

D. The omnidirectional antenna hanging height is recommended to exceed 12m

The outdoor bridge backhaul needs to focus on confirming the installation of the AP at the node and paying attention to the transmission path between the nodes. What is the correct statement about leaf nodes, aggregation nodes, and transmission paths?

A. If the leaf node needs to be used for coverage, it is necessary to pay attention to the outdoor coverage of the survey.

B. If there are multiple aggregation points, you need to confirm the location of each aggregation point. Each aggregation point also needs to confirm the AP installation location and power supply mode.

C. There should be no obstructions or distances between the convergence points and leaf nodes.There are allowed between the relay nodes and the convergence points, relay nodes and leaf points.Obstacle obstruction

D. The transmission path is the path between the stations. In the site survey, it is necessary to confirm the distance between the connected nodes. The PMP mode needs to confirm the most

Which of the following options is incorrect about the FIT AP description?

A. FIT AP is a traditional AP. In addition to providing basic wireless connectivity, it also provides security, management, and performance enhancements

B. FIT AP cannot be used in conjunction with AC

C. FIT AP differentiates from traditional FAT APs, providing only reliable, high-performance wireless connectivity, while stripping other features

D. FIT AP must be used in conjunction with AC

In the WLAN security access authentication technology, which way is the air interface packet encrypted?

A. MAC certification

B. Portal authentication

C. PSK certification

D. Wireless 802.1x authentication

What are the advantages of Mesh deployment compared to WDS deployment?

A. Mesh deployment equipment costs less

B. Mesh supports redundant links

C. Mesh network can be deployed quickly and can dynamically increase network coverage

D. All APs in Huawei support Mesh features.

The following is the correct statement about the requirements for confirming the on-site environmental

information during the WLAN site survey process?

A. Confirm whether the site is completely consistent with the architectural drawings, and highlight the inconsistent areas, try to take photo records, and mark them in the drawings.Room number on site

B. Take photos of the scene as thoroughly as possible in the room, especially the installation location of the equipment, the overall coverage area, the internal building structure, and new obstacles.Focus on the outdoor coverage, only need to focus on the obstacles between the AP and the coverage area.

C. In the indoor survey, the obstacle type is distinguished from the drawings, and the actual position and material of each type of obstacle are marked. Different obstacles are used differently.Color marking and testing its 2.4G and 5G attenuation values

D. During indoor survey, pay attention to other obstacles that are not drawn but affect the covering effect, such as load-bearing columns and artificially added partitions during decoration.Large objects such as broken and suspended ceilings

E. Outdoors need to pay attention to the height and shielding range of obstacles on the site. For irregular obstacles (such as trees), try to take photo records.

In the WLAN coverage, the accuracy of wireless positioning is closely related to AP signal coverage.

A. True

B. False

Which of the following is the function of the WLAN Survey Pad?

A. AP photo and antenna pre-installation location photo

B. Wi-Fi interference source search and annotation information function

C. Obstacle attenuation test and report generation

D. RF signal collection and mapping of obstacles and obstacles

E. Addition of switches and drawing of room components

F. Scale setting and floor property settings
