Which of the following is the port number for MySQL database service?

• A. 3306
• B. 5432
• C. 8080
• D. 80

Answer: (A)

The MySQL database service primarily operates on port number 3306. This port is designated for MySQL server communications and is the default port used for connecting client applications to the MySQL database. When a client wants to connect to a MySQL database server, it typically sends its requests to this specific port, allowing the server to handle the database operations requested by the client. In contrast, the other port numbers listed are associated with different services. Port 5432 is commonly used for PostgreSQL, a different relational database system. Port 8080 is often used for web services, typically as an alternative to port 80, which is the standard port for HTTP traffic. Thus, recognizing the specific role of each port number is essential in the context of networking and database management.
