Microsoft SQL Server typically listens on which port range for database connections?

Explanation:
SQL Server uses port 1433 for direct TCP connections by default. When you connect to a named instance, the SQL Server Browser service helps clients find the correct port by listening on UDP 1434. So using 1433/1434 covers both standard direct connections and instance discovery, which is why this pair is the correct choice. The other options correspond to web traffic (80/443) and SSH (22/23), not database connections.
