What is the standard TCP port that a PostgreSQL server instance listens on by default?
- A 3306 (Standard for MySQL/MariaDB instances)
- B 5432 (Standard for PostgreSQL instances)
- C 6379 (Standard for Redis/Memcached instances)
- D 8080 (Standard for HTTP Proxy/Server instances)
Answer: B. 5432 (Standard for PostgreSQL instances)
5432 is the IANA-assigned default for PostgreSQL. Knowing common ports is essential for firewall configuration and connection string troubleshooting in cloud and local environments.
One system design question a day, with spaced repetition so the ones you miss come back.
