問題文

The management address of the chassis pair does not change when the primary role moves from one module to the other. Why is that arrangement useful?

選択肢

1. The tools and the scripts learn the new address from the module that has taken the primary role, because that module announces itself on the management segment.
2. The tools and the scripts connect to both modules at once and use whichever one answers, because the two modules present the same configuration database.
3. The tools and the scripts that talk to the platform keep working after the role moves, because the address they use stays the same.
4. The tools and the scripts are restarted after the role moves and pick up the new address, because the platform writes it into their configuration files.
