Comprehensive and Detailed Explanation:

To manually pair a Remote Engine with Talend Cloud, you can set the pairing key using the following

methods:

In the Remote Engine web service page (Option B):

Access the Remote Engine's web interface, typically available at http://localhost:8043/configuration.

Enter the pairing key obtained from the Talend Management Console.

Click on PAIR REMOTE ENGINE to establish the connection.

In the key configuration file of the engine (Option C):

Locate the preauthorized.key.cfg file in the Remote Engine's etc directory.

Open the file and paste the pairing key into the remote.engine.pre.authorized.key parameter.

Save the changes and restart the Remote Engine to apply the configuration.

Why not other options?

Option A: Setting the pairing key in Talend Studio's p

is not applicable for pairing a Remote

Engine.

Option D: While it's technically possible to pass the pairing key as a parameter in the engine's run

script, it's not the standard or recommended method.
