ジョー。IT 部門のユーザーは、Linux サーバー上の機密ファイルへの変更を保存できません。1s -1& は次のリストを示します。 次のコマンドのうち、サーバー技術者が他のユーザーに過剰なアクセスを許可せずに Joe にアクセスを許可できる最も適切なコマンドはどれですか?
正解:C
Explanation The chmod command is used to change the permissions of files and directories. The g+w option means to grant write permission to the group owner of the file. Since Joe is a member of the IT group, which is also the group owner of the file, this command will allow him to save changes to the file without affecting the permissions of other users.
