The following description of the BYOD networking of large enterprises is wrong?

A. The network is divided into access layer, distribution layer and core layer.

B. AP is connected to the access layer switch. It is recommended to use a PoE switch.

C. AC can be implemented using the built-in AC card of the core switch.

As shown in the figure below, a city will install cameras (2 per school) in the entrances of multiple schools (yellow points in the picture). The camera does not support wireless functions, and there is only one network port. There is no switch on site, customers want to pass The WLAN passes the data back to the location of Main C4 in the figure (red standard Note), the two points connecting the red line in the figure are 3km apart. According to the calculation of 2Mbps bandwidth for each camera, there is a line of sight between the school gate and Main C4. Which of the following solutions can meet the above scenarios begging?

A. Each school deploys 1 AT815SN and 1 AP6510DN (with external antenna)

B. One AT815SN and one AP8030DN per school

C. 2 AP8130DN (with external antenna) deployed in each school

D. 2 AP6610DN (with external antenna) deployed in each school

E. Two AP6510 (with external antenna) deployed in each school

What is the correct description of the indoor distribution type AP6310SN?

A. The power splitter has multiple interfaces. When signals enter from any one interface, they are equally divided into multiple signal outputs.

B. When the AP is at the center of the room division network, it is recommended to use a single power splitter for direct splitting.

C. When the AP is at one end of the room division network and the coverage area is large, it is recommended to use a coupler for signal splitting.

D. Power splitters and couplers cannot be used in the same network at the same time

Regarding WLAN mobility capabilities, the following statement is wrong?

A. When forwarding across a Layer 3 IP network, it is recommended to use centralized forwarding mode.

B. Only the centralized forwarding mode can be used to support roaming between different VLANs under the same aggregation gateway.

C. AC6005 does not support fast roaming with key caching

D. Roaming in the same VLAN belongs to Layer 2 roaming
