Which of the following sequences in the vi editor saves the opened document and exits the editor? (Choose TWO correct answers.)

From `vi`'s normal mode, typing `ZZ` (capital Z twice) is a common shortcut command that saves any changes made to the file and then exits the editor.

`ctrl :w!` is incorrect; entering command-line mode is done with Esc then `:`, not Ctrl.

`esc zz` (lowercase z twice) is not a standard `vi` command for saving and exiting; the command is `ZZ` (uppercase).

From `vi`'s normal mode, typing `:` enters command-line mode. The `wq!` command then writes (saves) the file, quits the editor, and the `!` forces the action even if the file is read-only (permissions permitting).

`ctrl XX` is not a standard `vi` command for saving and exiting the editor.
