A. The WPS process contains a cryptographic vulnerability The original permissions are retained If a file is copied from one location to another, the newly created file will inherit the permissions from the parent object. If a file is moved, however, the only thing that changes is the pointer to the file location; the moved file is essentially the same file, so none of the permissions are modified. The moved file will have the exact same permissions it had before the move. You've moved a file from one folder on an NTFS volume to another folder on the same NTFS volume. What has happened to the permissions of the file after the move? A. The permissions are inherited from the new parent object Smart card A smart card often contains a digital certificate to create a unique card that cannot be duplicated elsewhere.
