An administrator has an existing FlexVol accessed by Linux hosts over NFSv3. A CIFS share to the same FlexVol was created for SMB access. Windows users are unable to view the share. CIFS share permissions allow for read and write access for the Windows users.
What does the administrator need to modify to allow SMB access?
In a scenario where both NFS and SMB access are needed on the same FlexVol, the security style of the FlexVol must be considered. FlexVols can have a security style of NTFS, UNIX, or mixed. Since the shared access is currently configured for Linux hosts using NFSv3 and now needs to be accessed by Windows hosts using SMB, the security style must support both protocols. Setting the security style to 'mixed' allows both NFS and SMB protocols to function correctly by translating permissions appropriately. Therefore, the administrator should modify the security style to 'mixed' to enable SMB access alongside NFS access.
Very interesting question - it can be B - if you configure access protocol as NFS only, you need to add SMB. It can be C - you can change security style to mixed. It can be D - you can add user mapping. All three seems correct.

C also seems legit - if you change security style to mixed you can use normal ntfs permissions and you don't have to map windows users to Unix names
D option
