   A PowerScale cluster is used by both NFS and SMB clients. An administrator changes the POSIX permissions on a file from 644 to 640. How will this affect SMB clients that have been granted access via an ACL that previously allowed 'Everyone' read access?

   • ASMB clients will lose read access because the 'other' permissions are now removed.
   • BSMB clients will still have read access because the ACL is independent of POSIX permissions.
   • CSMB clients will lose all access because POSIX permissions take precedence over ACLs.
   • DSMB clients will retain read access only if the ACL has an entry that grants it, because OneFS evaluates the ACL and the POSIX bits together.
