6.Which four statements are true about database instance behavior?

A) Redo log files can be renamed in mount state.

B) Datafiles can be renamed in mount state.

C) All dynamic performance views (v$ views) return data when queried from a session connected to an Instance in nomount state.

D) An spfile can be updated when connected to an idle instance.

E) The consistency of redo logs and data files is checked when mounting the database.

F) An idle instance is created when a startup nomount is successful.

Answer：ABDF

(解析：答案 AB 是沒有問題的，但是這道題的 an idle instance 指的是什麼不明確，如果一個實例沒有啓動，那麼我們連接的時候會告訴我們：Connected to an idle instance.，所以這裏不清楚實例啓動後是不是算是 idle instance，如果是，那麼答案DF 就是對的。交流3組：1015267481)
