• Question 397:

  An administrator exports a newly created file system and finds two directories, called etc and lost+found. The administrator does not want these directions to appear in the export. What should the administrator do to address this issue?

  A. The administrator should delete the directories

  B. Create a subdirectory below the root of the file system and export it

  C. Nothing, this is normal and these two directories will show in all exports

  D. The administrator should change the attribute of these directories to hidden

  Correct Answer: B

  Explanation: When an uxfs file system is created, by default it contains at its root level two key directories; .etc and lost +found. These directories are extremely important to the function and integrity of the file system. The .etc directory contains configuration files and lost+found contains files that are restored after a system crash, or when a partition has not been unmounted before a system shutdown. In order to keep these directories safe, export a directory instead of the root file system. This procedure hides theses directories protecting them from being removed, or accessed by non-administrators users on the enterprise network.
