A: it dipends how it is copied: "A copy of a realm-protected file is not realm-protected unless the copy is made in a security realm-protected directory.
Some applications, such as the vi editor, re-create a file when the file is modified. The modified file is saved as a temporary file, the original file is removed, and temporary file is copied with the original file name as the destination name. This process creates a new file. If the new file is created in a realm-protected directory, the security policies of the realm also apply to the new file. If the new file is not created in a realm-protected directory, then the new file is not realm-protected. If you are planning to copy a realm-protected file, you should ensure that the parent directory is also security realm protected.
"
E is wrong - there is no role separation with acfsutil encr init command.
