問題文

Both the client and the server leave the encryption setting in the Oracle Net profile at its default value. Which outcome does the resulting connection have?

選択肢

1. The session falls back to the checksum only.
2. The session runs without encryption because neither of the two sides asks for it.
3. The session fails because the two sides cannot agree on an algorithm.
4. The session runs with encryption because the default value asks for it on both of the sides.
