Which of the following is wrong about the configuration of the Huawei Oceanstor 9000 CIFS share?

• A.After the Guest is enabled, the user does not need to enter the username and password when accessing the shared directory on the client
• B.After the mandatory signature is checked, the client will be forced to use the signature function. If the client is not set to start state, Oceantor9000 will reject the client's data access request
• C.After Notify is enabled, a client's change operation in a directory cannot be sensed by other clients that are accessing this directory and its parent directory
• D.When oplock (Opportunistic locking) is enabled, files will be cached locally before being sent to the shared storage, which helps to improve client access efficiency
