The following is the correct description of the AC deployment method?

A.

AC deployment can be divided into two types: side-by-side deployment and direct-attached deployment.

B.

The side-by-side networking is a superposition of the existing network. It has fewer modifications to the existing network and is quick and convenient to deploy. In addition, according to the control requirements for wireless users,

Choose direct forwarding or tunnel forwarding mode according to your needs

C.

In the direct connection network deployment mode, because the AC is connected in series in the network, the management data and user data between the AP and the AC must pass.

CAPWAP tunnel forwards

D.

Direct connection networking is mainly used in large campus network scenarios. The AP size in the network is recommended to be 1000 or more.

What is wrong about the description of antenna azimuth and downtilt below?

A.

Azimuth specifies the coverage direction of the antenna

B.

Azimuth can be understood as the angle that the plane in the north direction rotates clockwise to coincide with the plane of the antenna.

C.

Downtilt angle affects the coverage of the antenna in the vertical direction

D.

The downtilt angle is the angle between the antenna and the vertical plane
