Which of the following are correct steps in a LAN based backup job? (Multiple Choice)

In a standard LAN-based backup architecture, the process is centrally managed by a backup server. The data flow begins when the agent, installed on the application server (client), reads the data designated for backup. This data is then transmitted over the production LAN to the backup media server. The media server's function is to receive this data stream and write it to the connected physical backup storage device, such as a tape library or a disk-based backup system. This entire data transfer process utilizes the existing local area network.

A. The agent sends data to the media server, not directly to the backup device. Direct agent-to-device communication is a feature of LAN-Free backup.
D. The backup server, as the control node, sends the "start-backup" command to the agent on the application server, not to the backup device.

describes the traditional backup architecture where the backup client (agent) sends data over the LAN to a backup server/media server

which then writes to the backup device.
