問題文
A rack server is delivered and racked, but no operating system has been installed yet. The operator needs to reach its console and control its power. Which facility makes that possible?
選択肢
- A management controller on the server board answers on its own network port, and it presents the console and the power controls whatever state the host software is in.
- The central management platform installs an agent on the server, and the operator uses that agent to reach the console.
- Its operating system exposes a remote console service, and the operator connects to that service over the production network.
- One upstream switch relays the console output of the server, and the operator reads it from the port to which the server happens to be cabled.
