Question # 11

Which of the following options are the principles for engineers to deploy APs?

Minimize the number of signals passing through obstacles

Ensure that the AP is facing the target area

Try to install in a shelter

AP is placed away from interference sources

Question # 12

What is wrong about the Fresnel region?

The Fresnel zone of the radio beam is an ellipsoidal region that surrounds the visible line of sight directly.

The antenna installation position should ensure that the two nodes of the link are visible, and try to ensure that there is no obstruction in the Fresnel zone.

Two nodes of the site link are visible, and the Fresnel zone boundary is blocked, which will not affect the link transmission effect.

The distance between the stations is 2 kilometers, and the radius of the Fresnel area is about 6 meters.

Question # 13

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

WLAN overlay networking

Independent management of wired and wireless services

Wired and wireless traffic convergence and forwarding

Unified management of wired and wireless users

Question # 14

Which two APs below support the 802.11ac standard?

AP5030DN

AP5130DN

AP6510DN

AP7110DN

Question # 15

Which of the following is the highest security strength of the encryption algorithm?

WEP

CCMP

TKIP

DES

Question # 16

When conducting WLAN security planning, in order to support guest registration, what is the recommended authentication method for visitors?

WEB certification

WPA-PSK

WEB-Portal certification

dot1x certification

Question # 17

What is the correct description of the tools before the actual site survey of the WLAN?

Tape measure is mainly used for indoor scene obstacle test and trace distance measurement.

The range finder is mainly used to measure the outdoor mixing height in outdoor scenes, or the distance between obstacles, the length of the venue, etc.

Hotspot mobile phones can be used as both a signal source and a signal scan

Focus on the installation location of the camera, the overall coverage area, the building structure, and new obstacles in the outdoor coverage scene.

Question # 18

What is the time interval of Short GI?

100ns

200ns

400ns

800ns

Question # 19

Which of the following devices has an internal antenna?

AP6510DN

AP8030DN

AP8130DN

AT815SN

Question # 20

The following is about using the AP6310SN to create a new WLAN room subsystem. What is wrong with this?

The number of antennas in a single AP band is 4~8, and it is recommended that no more than 10 antennas under normal circumstances.

Under normal circumstances, the distance between the AP and the far-end room sub-antenna is controlled within 50 meters, and it is recommended not to exceed 60 meters.

In a typical room sub-scenario, it is recommended that the output power of each antenna be basically the same, and the output power is controlled at 12~18dBm. The specific power selection and field

Strong demand is related to the wall structure

There is interference between the room division antennas of the same AP, so it cannot be placed intensively according to requirements.
