It s redirected using a communication method to pass I/O to the other SP.

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


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.
