  2. The Connections close as and when the open transaction completes

  3. The Existing connections are left untouched as the listener only initiates the connections

  4. None of the Above


Correct Option: C

AI Explanation

To answer this question, we need to understand the relationship between the Listener and the database connections.

The Listener is responsible for accepting incoming client connections and establishing a connection between the client and the database server. Once the connection is established, the Listener's role is complete, and it does not actively manage or control the existing connections.

Given the scenario where the Listener is shut down while the database is still running, the existing connections will be left untouched. This means that the connections between the client and the database server will remain open and active, even though the Listener is no longer available.

Therefore, the correct answer is:

C. The existing connections are left untouched as the Listener only initiates the connections.
