Which port is the default connection port for MongoDB?

The default connection port for MongoDB is 27017. This port is used by the MongoDB server to listen for incoming connections from clients. When a MongoDB instance is set up, it automatically configures itself to use this port, enabling clients to connect to the database without the need for additional configuration unless specified.

Using this default port simplifies the connection process since developers and applications can communicate with the database seamlessly. While other ports may be utilized for different applications or databases, 27017 is widely recognized as the standard for MongoDB, ensuring compatibility and reducing confusion.
