How can SSL/TLS be enabled for a MongoDB connection?

Enabling SSL/TLS for a MongoDB connection is accomplished by configuring the server and client connection string. This involves specifying proper parameters in the connection string used by the client, which informs MongoDB to establish a secure connection through SSL/TLS.

For the server side, settings in the MongoDB configuration file (such as mongod.conf) must be adjusted to enable SSL by defining the paths to the necessary SSL certificates and setting the appropriate flags. The client, which may include applications or drivers connecting to MongoDB, must be aware of these configurations to properly negotiate the TLS handshake and maintain a secure communication channel.

The other options do not directly pertain to the enabling of SSL/TLS. For instance, changing the database location does not impact the security of the data in transit. Using a third-party application may add layers of complexity but won't inherently activate SSL/TLS protocols on its own. Upgrading the database version might offer improvements or enhanced features, but the fundamental action to enable SSL/TLS lies within the configuration of both server and client connection strings.
