Warehouse horizontal plane channel planning

B.

Warehouse vertical stereo channel planning

C.

Scan code terminal channel support

D.

Scan code terminal rate support

A.

Root against four leaves

B.

One-hop relay between root and leaf

C.

Two-hop relay between root and leaf

In an outdoor WLAN deployment scenario, the channel design must consider the interference of the radar channel.

A.

True

B.

False

As shown in the figure below, what is the best channel for the AP in the lower left corner?

A.

1 channel

B.

6 channels

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

In the wireless high-density access scenario, what are the main technical points used?

A.

Using room divider antenna

B.

Automatic packet-by-packet power control

C.

Low speed users limit access

D.

5G frequency band priority access

E.

Maximize AP transmit power

The throughput test of the wireless terminal in the WLAN wireless city scenario, the following description is correct under the same conditions?

A.

TCP flow is larger than UDP flow

B.

TCP flow is equal to UDP flow

C.

TCP flow is smaller than UDP flow

D.

Other options are wrong.

Which two APs below support the 802.11ac standard?

A.

AP5030DN

B.

AP5130DN

C.

AP6510DN

D.

AP7110DN

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.

The WLAN high-density venue business can achieve 100% concurrent users under a good experience.

A.

True

B.

False

When using the WLAN planning tool, which type of area should be used for areas with coverage field strength requirements but no access and bandwidth requirements?

A.

Key coverage areas

B.

Ordinary coverage area

C.

Blind area

D.

AP deployment area

If you use a layered network design method in enterprise network design, what are the three levels of network?

A.

Access layer

B.

Convergence layer

C.

Transport layer

D.

Core layer

What is the correct statement about the function of the WLAN Survey PAD survey tool?

A.

The floor attribute is set for some basic information of this floor, which has great reference value for the installation method of AP when planning later.

B.

The surveying personnel select the AP hotspot to enter the test session, and locate the approximate location of the interference source by moving the field strength change, and then input the distance.

Can calculate the power of the interference source

C.

The classification of obstacles is mainly to draw the types of obstacles on the drawings.

D.

The scale function is to let the surveyors know the size of the drawing scale more accurately.

What is wrong about the Fresnel region?

A.

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

B.

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.

C.

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

D.

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