Which of the following is not required for connecting to Autonomous Database (ADB) via SQL...

Connecting to Autonomous Database (ADB) via SQL Developer requires specific parameters. The correct answer is:

Connection Name (E):The Connection Name is a user-defined label in SQL Developer to identify the connection in the tool’s interface. It is not a technical requirement for establishing the database connection itself, making it optional in terms of connectivity.

The required parameters are:

Password (A):Essential for user authentication alongside the username.

Service (B):Refers to the service name (e.g., high, medium, low) from the wallet’s tnsnames.ora, specifying the performance level and connection type.

Username (C):Required to identify the database user.

Database name (D):Needed to specify the target database or PDB within the ADB instance, typically provided via the wallet configuration.

Without A, B, C, and D, the connection cannot be established, but E is merely a convenience.
