Your Windows clients were able to access your CIFS SVM yesterday. Today they are no longer able to access the CIFS SVM on your NetApp cluster. Your IT security team just pushed out a new group policy to enhance security.
In this scenario, which statement is true?
The most likely cause of the issue is that the new group policy enhanced security by disabling older, insecure SMB protocols like SMBv1. If your CIFS SVM is configured to use SMBv1 and SMBv2, the clients will no longer be able to access the CIFS SVM if only newer protocols such as SMBv3 are being allowed by the new security policy.
A - it would not work also the day before. B- enhanced sec by disabling unsecure SMB1
