A client-server application has become very popular and hundreds of users are accessing the Oracle Server daily. Which networking solution should be implemented to ensure that all users can access the Oracle Server?

Oracle Connection Manager is specifically designed to handle large numbers of concurrent client connections through connection pooling and multiplexing. It acts as an intermediary that can efficiently manage hundreds or thousands of client sessions to a single server instance. Dedicated Server (option A) would create one server process per user - resource-intensive for hundreds of users. Directory Naming (option B) is for name resolution, not connection scaling. Heterogeneous Services (option D) is for non-Oracle data source integration.
