Which database management system is associated with port 5432?

MySQL
MongoDB
Postgres
SQLite

The correct answer is: Postgres

Port 5432 is the default network port for PostgreSQL, which is an object-relational database management system. This association is crucial for database administrators and analysts when configuring firewall settings, connecting applications, or troubleshooting network issues related to database access. Understanding specific ports tied to certain database systems helps in securing the environment and ensuring that only the right traffic can access the database, which is essential in maintaining data integrity and confidentiality. For the other options, MySQL primarily uses port 3306, MongoDB uses port 27017, and SQLite is a file-based database that does not operate over a network port. This distinction highlights why the choice of PostgreSQL is the correct answer.
