同学你好~
as long as the CEO maintains the confidence of the board of directors
只要CEO 保持着董事会的信任
the confidence of the board of directors 董事会的信任，董事会对CEO的信任
所以是董事会trust CEO

如果是信任……，应该是confidence in sth，比如
The players all have confidence in their manager.
队员都信赖他们的教练。
如果是CEO信任董事会，应该是maintains the confidence in the board of directors

祝同学学习进步~
