   An administrator is troubleshooting an access issue on a PowerScale cluster. A user reports that they cannot write to a file, even though they are a member of the group that has write permission in the ACL. The ACL shows: user::rw-, group:dev:rwx, mask::r-x, other::---. What is the most likely cause?

   • AThe user is not the owner of the file.
   • BThe file system is mounted read-only.
   • CThe ACL mask is restricting the group's effective permissions to read and execute.
   • DThe user is also a member of another group that denies write access.
